Microsoft SSAS Connection Details

Introduction

Connector Version

This documentation is based on version 25.0.9368 of the connector.

Get Started

Microsoft SQL Server Analysis Services Version Support

The connector wraps the complexity of connecting to Microsoft SQL Server Analysis Services in a standard driver: Authenticate with HTTP, Windows (NTLM), or Kerberos. You can then execute SQL-92 queries or pass through MDX queries from relational tools.

Establish a Connection

Connect to Microsoft SQL Server Analysis Services

To connect, set the URL property to a valid Microsoft SQL Server Analysis Services endpoint and provide authentication. The connector must connect to Microsoft SQL Server Analysis Services instances hosted over HTTP with XMLA access. See the Microsoft documentation to configure HTTP access to Microsoft SQL Server Analysis Services.

Authenticate to Microsoft SQL Server Analysis Services

The connector supports the major authentication schemes, including HTTP and Windows.

Set AuthScheme to use the following authentication types.

Anonymous Authentication

If anonymous authentication is available, set AuthScheme to none to avoid authentication.

Basic

Set SQL Server database User and Password and set AuthScheme to "BASIC".

Windows (NTLM)

Set the Windows User and Password and set AuthScheme to "NTLM".

Kerberos

Please see Using Kerberos for details on how to authenticate with Kerberos.

Secure Microsoft SQL Server Analysis Services Connections

By default, the connector attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.

Use Kerberos

Kerberos

To authenticate to Microsoft SQL Server Analysis Services with Kerberos, set AuthScheme to NEGOTIATE.

Authenticating to Microsoft SQL Server Analysis Services via Kerberos requires you to define authentication properties and to choose how Kerberos should retrieve authentication tickets.

Retrieve Kerberos Tickets

Kerberos tickets are used to authenticate the requester's identity. The use of tickets instead of formal logins/passwords eliminates the need to store passwords locally or send them over a network. Users are reauthenticated (tickets are refreshed) whenever they log in at their local computer or enter kinit USER at the command prompt.

The connector provides three ways to retrieve the required Kerberos ticket, depending on whether or not the KRB5CCNAME and/or KerberosKeytabFile variables exist in your environment.

MIT Kerberos Credential Cache File

This option enables you to use the MIT Kerberos Ticket Manager or kinit command to get tickets. With this option there is no need to set the User or Password connection properties.

This option requires that KRB5CCNAME has been created in your system.

To enable ticket retrieval via MIT Kerberos Credential Cache Files:

1. Ensure that the KRB5CCNAME variable is present in your environment.
2. Set KRB5CCNAME to a path that points to your credential cache file. (For example, C:\krb_cache\krb5cc_0 or /tmp/krb5cc_0.) The credential cache file is created when you use the MIT Kerberos Ticket Manager to generate your ticket.

3. To obtain a ticket:

   1. Open the MIT Kerberos Ticket Manager application.
   2. Click Get Ticket.
   3. Enter your principal name and password.
   4. Click OK.

   If the ticket is successfully obtained, the ticket information appears in Kerberos Ticket Manager and is stored in the credential cache file.

The connector uses the cache file to obtain the Kerberos ticket to connect to Microsoft SQL Server Analysis Services.

Keytab File

If your environment lacks the KRB5CCNAME environment variable, you can retrieve a Kerberos ticket using a Keytab File.

To use this method, set the User property to the desired username, and set the KerberosKeytabFile property to a file path pointing to the keytab file associated with the user.

User and Password

If your environment lacks the KRB5CCNAME environment variable and the KerberosKeytabFile property has not been set, you can retrieve a ticket using a user and password combination.

To use this method, set the User and Password properties to the user/password combination that you use to authenticate with Microsoft SQL Server Analysis Services.

Enable Cross-Realm Authentication

More complex Kerberos environments can require cross-realm authentication where multiple realms and KDC servers are used. For example, they might use one realm/KDC for user authentication, and another realm/KDC for obtaining the service ticket.

To enable this kind of cross-realm authentication, set the KerberosRealm and KerberosKDC properties to the values required for user authentication. Also, set the KerberosServiceRealm and KerberosServiceKDC properties to the values required to obtain the service ticket.

Fine-Tuning Data Access

Fine Tuning Data Access

Set the following other properties may also be useful in certain situations:

• UseMDX: Indicates if MDX queries are being submitted. By default this is false, which will cause the driver to accept only SQL-92 compliant queries. Setting this property to true will cause all queries to be passed through directly to Microsoft SQL Server Analysis Services.

• ExtraProperties: Additional properties to submit along with an MDX query. Only meaningful if UseMDX is true.

• IncludeJoinColumns: Boolean indicating if extra columns used to make ON conditions with joins should be added.

  These do not come back with any values - they are added purely to enable tools that require them in order to automatically set up relationships between tables when creating joins.

• ResponseRowLimit: Sets a calculated limit on the number of rows to allow the user to select before returning an error.

  Because queries are being translated to MDX, selecting only a few columns may exponentially multiply the number of expected results.

  For this reason, ResponseRowLimit is available to try and give some guidance on what types of queries are likely to result in a Timeout. May be disabled by setting to 0.

Retrieve Analysis Services Data

Microsoft SQL Server Analysis Services is an OLAP database that exposes data as cubes, which you query with MDX (multidimensional expressions). The connector models these cubes in relational views that you can query with SQL-92. The following mapping is for the layout of the model:

• Catalog - Displayed in the connector as a Catalog.
• Cube - Displayed in the connector as a Schema.
• Measure - Available in the connector under the special Measures view.
• Dimension - Each dimension is exposed as a view.
• Level - Each individual level of a hierarchy is exposed as a column on the appropriate dimension view.

Join Measures and Dimensions

In order to retrieve measures per specific level value, issue a join between the Measure view and any Dimension or set of dimensions. For example, issuing the following will retrieve the number of customers in each city:

SELECT m.[Customer Count], c.[City]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m

Note that there is no ON condition necessary. That is because tables are already related appropriately in Microsoft SQL Server Analysis Services. If you are using a tool that requires ON conditions, set IncludeJoinColumns to true. This will append a number of foreign key columns to each view which will relate them to one another another. These columns will not return data on their own, but may be picked up on automatically with tools to construct the ON conditions for joins where needed.

Aggregate Data

Data stored in Microsoft SQL Server Analysis Services is already aggregated. In many cases, attempting to retrieve an aggregate may be syntactically equivalent to not specifying anything. For example, the following query will return the exact same data as the previous:

SELECT SUM(m.[Customer Count]), c.[City]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m
GROUP BY c.[City]

The exception to this rule is when an aggregation of filtered results is requested. In such cases, a calculation will be requested from Microsoft SQL Server Analysis Services. For example, to calculate the sum and average of customers in France and Germany:

SELECT SUM(m.[Customer Count]), AVG(m.[Customer Count]), c.[Country]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m
WHERE c.[Country] IN ('France', 'Germany')
GROUP BY c.[Country]

Select Multiple Hierarchies

In Microsoft SQL Server Analysis Services, individual dimensions are made up of hierarchies which may have one or more levels. For instance, the AdventureWorks Customers table has City, Country and Gender. City and Country are part of the same hierarchy while Gender is its own hierarchy.

When selecting multiple hierarchies, the method to support this is to cross join the values in MDX. While not obvious from a relational table model of the data as the connector presents, this can cause for very expensive queries to be executed. For example, executing the following:

SELECT c.[Country], m.[Customer Count]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m

Will result in 6 rows. However, selecting Gender as well:

SELECT c.[Country], c.[Gender], m.[Customer Count]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m

Will now result in 12 rows. It is because Gender and Country are on different hierarchies, thus a crossjoin is required in order to return both together. Each additional hierarchy added to the SELECT will multiply the total results by the number of available values in that hierarchy. Thus to get a count of how many rows to expect, one can execute the following:

SELECT (Count(c.[Country])*COUNT(c.[Gender])) AS totalrows
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c 

Response Row Limit

Due to how selecting multiple hierarchies will multiply the total number of result rows, it is possible to balloon the number of response rows very quickly, which will result in timeouts. In order to try and give some visibility into what queries will be very expensive, the ResponseRowLimit connection property has been added as a mechanism to try and guide users into better practices. When set, it will calculate how many rows to expect before any query is executed. If the number of predicted rows exceeds the limit, an error will be thrown indicating how many rows to expect back with the query.

It is recommended to select only the columns required or to apply a WHERE criteria. Both can significantly reduce the number of response rows, which will have a huge impact on performance. If you are already familiar with the connector and what queries may be expensive, ResponseRowLimit may be disabled by setting it to 0.

Important Notes

Configuration Files and Their Paths

• All references to adding configuration files and their paths refer to files and locations on the Jitterbit agent where the connector is installed. These paths are to be adjusted as appropriate depending on the agent and the operating system. If multiple agents are used in an agent group, identical files will be required on each agent.

Advanced Features

This section details a selection of advanced features of the Microsoft SQL Server Analysis Services connector.

User Defined Views

The connector supports the use of user defined views, virtual tables whose contents are decided by a pre-configured user defined query. These views are useful when you cannot directly control queries being issued to the drivers. For an overview of creating and configuring custom views, see User Defined Views.

SSL Configuration

Use SSL Configuration to adjust how connector handles TLS/SSL certificate negotiations. You can choose from various certificate formats. For further information, see the SSLServerCert property under "Connection String Options".

Proxy

To configure the connector using private agent proxy settings, select the Use Proxy Settings checkbox on the connection configuration screen.

Query Processing

The connector offloads as much of the SELECT statement processing as possible to Microsoft SQL Server Analysis Services and then processes the rest of the query in memory (client-side).

For further information, see Query Processing.

Log

For an overview of configuration settings that can be used to refine logging, see Logging. Only two connection properties are required for basic logging, but there are numerous features that support more refined logging, which enables you to use the LogModules connection property to specify subsets of information to be logged.

User Defined Views

The Jitterbit Connector for Microsoft SQL Server Analysis Services supports the use of user defined views: user-defined virtual tables whose contents are decided by a preconfigured query. User defined views are useful in situations where you cannot directly control the query being issued to the driver; for example, when using the driver from Jitterbit.

Use a user defined view to define predicates that are always applied. If you specify additional predicates in the query to the view, they are combined with the query already defined as part of the view.

There are two ways to create user defined views:

• Create a JSON-formatted configuration file defining the views you want.
• DDL statements.

Define Views Using a Configuration File

User defined views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The connector automatically detects the views specified in this file.

You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the connector.

This user defined view configuration file is formatted so that each root element defines the name of a view, and includes a child element, called query, which contains the custom SQL query for the view.

For example:

{
    "MyView": {
        "query": "SELECT * FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer WHERE MyColumn = 'value'"
    },
    "MyView2": {
        "query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
    }
}

Use the UserDefinedViews connection property to specify the location of your JSON configuration file. For example:

"UserDefinedViews", "C:\Users\yourusername\Desktop\tmp\UserDefinedViews.json"

Define Views Using DDL Statements

The connector is also capable of creating and altering the schema via DDL Statements such as CREATE LOCAL VIEW, ALTER LOCAL VIEW, and DROP LOCAL VIEW.

Create a View

To create a new view using DDL statements, provide the view name and query as follows:

CREATE LOCAL VIEW [MyViewName] AS SELECT * FROM Customers LIMIT 20;

If no JSON file exists, the above code creates one. The view is then created in the JSON configuration file and is now discoverable. The JSON file location is specified by the UserDefinedViews connection property.

Alter a View

To alter an existing view, provide the name of an existing view alongside the new query you would like to use instead:

ALTER LOCAL VIEW [MyViewName] AS SELECT * FROM Customers WHERE TimeModified > '3/1/2020';

The view is then updated in the JSON configuration file.

Drop a View

To drop an existing view, provide the name of an existing schema alongside the new query you would like to use instead.

DROP LOCAL VIEW [MyViewName]

This removes the view from the JSON configuration file. It can no longer be queried.

Schema for User Defined Views

In order to avoid a view's name clashing with an actual entity in the data model, user defined views are exposed in the UserViews schema by default. To change the name of the schema used for UserViews, reset the UserViewsSchemaName property.

Work with User Defined Views

For example, a SQL statement with a user defined view called UserViews.RCustomers only lists customers in Raleigh:

SELECT * FROM Customers WHERE City = 'Raleigh';

An example of a query to the driver:

SELECT * FROM UserViews.RCustomers WHERE Status = 'Active';

Resulting in the effective query to the source:

SELECT * FROM Customers WHERE City = 'Raleigh' AND Status = 'Active';

That is a very simple example of a query to a user defined view that is effectively a combination of the view query and the view definition. It is possible to compose these queries in much more complex patterns. All SQL operations are allowed in both queries and are combined when appropriate.

SSL Configuration

Customize the SSL Configuration

By default, the connector attempts to negotiate TLS with the server. The server certificate is validated against the default system trusted certificate store. You can override how the certificate gets validated using the SSLServerCert connection property.

To specify another certificate, see the SSLServerCert connection property.

Client SSL Certificates

The Microsoft SQL Server Analysis Services connector also supports setting client certificates. Set the following to connect using a client certificate.

• SSLClientCert: The name of the certificate store for the client certificate.
• SSLClientCertType: The type of key store containing the TLS/SSL client certificate.
• SSLClientCertPassword: The password for the TLS/SSL client certificate.
• SSLClientCertSubject: The subject of the TLS/SSL client certificate.

Data Model

Microsoft SQL Server Analysis Services is an OLAP database that exposes data as cubes, which you query with MDX (multidimensional expressions). The connector models these cubes in relational views that you can query with SQL-92, or MDX.

Accessing Cubes as Views

Microsoft SQL Server Analysis Services is fundamentally different from a relational database; reflecting these differences, the Jitterbit Connector for Microsoft SQL Server Analysis Services does not support many SQL-92 features found in a driver for an RDBMS. To bypass any limitations with query translation, you can submit pass-through MDX queries from the connector.

See Retrieving Analysis Services Data for query limitations and more information on querying Microsoft SQL Server Analysis Services.

Modeling Views Dynamically

You can query all of the cubes in your Microsoft SQL Server Analysis Services instance; when you connect, the connector retrieves the metadata from Microsoft SQL Server Analysis Services and displays the available dimensions and measures as columns for the views (cubes). The connector dynamically updates the schemas over subsequent connections.

Measure Attributes

By default, all measure attributes are listed in a 'Measures' view. However, you can set SplitMeasures to 'true' to split the measures view; the result is each measure attribute is included in its respective view based on the Measure Group value. Further classification based on 'Measure Directories' is not included.

Accessing Schema Information

Query the System Tables to access schema information and other connector metadata.

Dynamic Management Views

Dynamic Management Views (DMVs) are queries that return information about model objects, server operations, and the server health of your Analysis Services instance. These objects can be queried through the connector by setting UseMDX to 'true' and issuing the desired query:

SELECT * FROM $System.DBSchema_Tables
WHERE TABLE_TYPE = 'SCHEMA'
ORDER BY TABLE_NAME ASC  

Note that the DMV query syntax is based on a SQL SELECT statement, but does not support its full syntax. See the Analysis Services documentation on DMVs for more information.

System Tables

You can query the system tables described in this section to access schema information, information on data source functionality, and batch operation statistics.

Advanced Configurations Properties

The advanced configurations properties are the various options that can be used to establish a connection. This section provides a complete list of the options you can configure. Click the links for further details.

Authentication

Kerberos

SSL

Schema

Miscellaneous

Authentication

This section provides a complete list of authentication properties you can configure.

AuthScheme

The scheme used for authentication. Accepted entries are NTLM, Basic, Digest, None, and Negotiate.

Possible Values

NTLM, Basic, Digest, None, Negotiate

Data Type

string

Default Value

NTLM

Remarks

Together with Password and User, this field is used to authenticate against the server. NTLM is the default option. Use the following options to select your authentication scheme:

• NTLM: Set this to use your Windows credentials to authenticate.
• Basic: Set this to use HTTP Basic authentication.
• Negotiate: If AuthScheme is set to Negotiate, the connector will negotiate an authentication mechanism with the server. Set AuthScheme to Negotiate to use Kerberos authentication.
• Digest: Set this to use HTTP Digest authentication.

URL

The URL used to connect to the Microsoft SQL Server Analysis Services.

Data Type

string

Default Value

""

Remarks

The HTTP or HTTPS URL used to connect to the Microsoft SQL Server Analysis Services.

The connector must connect to Microsoft SQL Server Analysis Services instances hosted over HTTP with XMLA access. See the Microsoft documentation to configure HTTP access to Microsoft SQL Server Analysis Services.

User

Specifies the user ID of the authenticating Microsoft SQL Server Analysis Services user account.

Data Type

string

Default Value

""

Remarks

The authenticating server requires both User and Password to validate the user's identity.

Password

Specifies the password of the authenticating user account.

Data Type

string

Default Value

""

Remarks

The authenticating server requires both User and Password to validate the user's identity.

Kerberos

This section provides a complete list of Kerberos properties you can configure.

KerberosKDC

Identifies the Kerberos Key Distribution Center (KDC) service used to authenticate the user. (SPNEGO or Windows authentication only).

Data Type

string

Default Value

""

Remarks

The Kerberos properties are used when using SPNEGO or Windows Authentication. The connector requests session tickets and temporary session keys from the Kerberos KDC service, which is usually co-located with the domain controller.

If KerberosKDC is not specified, the connector tries to detect these properties automatically from the following locations:

• KRB5 Config File (krb5.ini/krb5.conf): If the KRB5_CONFIG environment variable is set and the file exists, the connector obtains the KDC from the specified file. If it is not found there, the connector tries to read from the default MIT location based on the OS: C:\ProgramData\MIT\Kerberos5\krb5.ini (Windows) or /etc/krb5.conf (Linux).
• Java System Properties: Using the system properties java.security.krb5.realm and java.security.krb5.kdc.
• Domain Name and Host: If the Kerberos Realm and Kerberos KDC cannot be inferred from another location, the connector infers them from the configured domain name and host.

KerberosRealm

Identifies the Kerberos Realm used to authenticate the user.

Data Type

string

Default Value

""

Remarks

A realm is a logical network, similar to a domain, that defines a group of systems under the same master KDC. Some realms are hierarchical, where one realm is a superset of the other realm, but usually realms are nonhierarchical (or “direct”) and the mapping between the two realms must be defined. Kerberos cross-realm authentication enables authentication across realms. Each realm only needs to have a principal entry for the other realm in its KDC.

The Kerberos properties are used when using SPNEGO or Windows Authentication. The connector requests session tickets and temporary session keys from the Kerberos KDC service, which is usually co-located with the domain controller. The Kerberos Realm can be configured by an administrator to be any string, but it is usually based on the domain name.

If Kerberos Realm is not specified, the connector will attempt to detect these properties automatically from the following locations:

• KRB5 Config File (krb5.ini/krb5.conf): If the KRB5_CONFIG environment variable is set and the file exists, the connector will obtain the default realm from the specified file. Otherwise, it will attempt to read from the default MIT location based on the OS: C:\ProgramData\MIT\Kerberos5\krb5.ini (Windows) or /etc/krb5.conf (Linux)
• Java System Properties: Using the system properties java.security.krb5.realm and java.security.krb5.kdc.
• Domain Name and Host: If the Kerberos Realm and Kerberos KDC could not be inferred from another location, the connector will infer them from the user-configured domain name and host. This might work in some Windows environments.

KerberosSPN

Identifies the service principal name (SPN) for the Kerberos Domain Controller.

Data Type

string

Default Value

""

Remarks

If the SPN on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, use this property to set the SPN to the KDC's URL.

KerberosKeytabFile

Identifies the Keytab file containing your pairs of Kerberos principals and encrypted keys.

Data Type

string

Default Value

""

Remarks

A keytab (short for “key table”) stores long-term keys for one or more principals. In most cases, end users authenticate to the KDC using their client secret (password). However, in situations where authentication or re-authentication happen using automated scripts and applications, it may be more efficient to use a keytab, which sends passwords to the KDC in encrypted form, automatically.

Keytabs are normally represented by files in a standard format, and named using the format type:value. Usually type is FILE and value is the absolute pathname of the file. The other possible value for type is MEMORY, which indicates a temporary keytab stored in the memory of the current process.

A keytab contains one or more entries, where each entry consists of a timestamp (indicating when the entry was written to the keytab), a principal name, a key version number, an encryption type, and the encryption key itself. They can be generated using kutil.

For example:

[admin@myhost]# ktutil

ktutil: addent -password -p starlord/myhost.galaxy.com@GALAXY.COM -k 1 -e aes256-cts-hmac-sha1-96
Password for starlord/myhost.galaxy.com:

ktutil: addent -password -p starlord/myhost.galaxy.com@GALAXY.COM -k 1 -e aes128-cts-hmac-sha1-96
Password for starlord/myhost.galaxy.com:

ktutil: addent -password -p starlord/myhost.galaxy.com@GALAXY.COM -k 1 -e des3-cbc-sha1
Password for starlord/myhost.galaxy.com:
ktutil: wkt /path/to/starlord.keytab

To display a keytab, use klist -k.

SSL

This section provides a complete list of SSL properties you can configure.

SSLClientCert

Specifies the TLS/SSL client certificate store for SSL Client Authentication (2-way SSL). This property works in conjunction with other SSL-related properties to establish a secure connection.

Data Type

string

Default Value

""

Remarks

This property specifies the client certificate store for SSL Client Authentication. Use this property alongside SSLClientCertType, which defines the type of the certificate store, and SSLClientCertPassword, which specifies the password for password-protected stores. When SSLClientCert is set and SSLClientCertSubject is configured, the driver searches for a certificate matching the specified subject.

Certificate store designations vary by platform. On Windows, certificate stores are identified by names such as MY (personal certificates), while in Java, the certificate store is typically a file containing certificates and optional private keys.

The following are designations of the most common User and Machine certificate stores in Windows:

For PFXFile types, set this property to the filename. For PFXBlob types, set this property to the binary contents of the file in PKCS12 format.

SSLClientCertType

Specifies the type of key store containing the TLS/SSL client certificate for SSL Client Authentication. Choose from a variety of key store formats depending on your platform and certificate source.

Possible Values

USER, MACHINE, PFXFILE, PFXBLOB, JKSFILE, JKSBLOB, PEMKEY_FILE, PEMKEY_BLOB, PUBLIC_KEY_FILE, PUBLIC_KEY_BLOB, SSHPUBLIC_KEY_FILE, SSHPUBLIC_KEY_BLOB, P7BFILE, PPKFILE, XMLFILE, XMLBLOB, BCFKSFILE, BCFKSBLOB

Data Type

string

Default Value

USER

Remarks

This property determines the format and location of the key store used to provide the client certificate. Supported values include platform-specific and universal key store formats. The available values and their usage are:

SSLClientCertPassword

Specifes the password required to access the TLS/SSL client certificate store. Use this property if the selected certificate store type requires a password for access.

Data Type

string

Default Value

""

Remarks

This property provides the password needed to open a password-protected certificate store. This property is necessary when using certificate stores that require a password for decryption, as is often recommended for PFX or JKS type stores.

If the certificate store type does not require a password, for example USER or MACHINE on Windows, this property can be left blank. Ensure that the password matches the one associated with the specified certificate store to avoid authentication errors.

SSLClientCertSubject

Specifes the subject of the TLS/SSL client certificate to locate it in the certificate store. Use a comma-separated list of distinguished name fields, such as CN=www.server.com, C=US. The wildcard * selects the first certificate in the store.

Data Type

string

Default Value

*

Remarks

This property determines which client certificate to load based on its subject. The connector searches for a certificate that exactly matches the specified subject. If no exact match is found, the connector looks for certificates containing the value of the subject. If no match is found, no certificate is selected.

The subject should follow the standard format of a comma-separated list of distinguished name fields and values. For example, CN=www.server.com, OU=Test, C=US. Common fields include the following:

SSLServerCert

Specifies the certificate to be accepted from the server when connecting using TLS/SSL.

Data Type

string

Default Value

""

Remarks

If using a TLS/SSL connection, this property can be used to specify the TLS/SSL certificate to be accepted from the server. Any other certificate that is not trusted by the machine is rejected.

This property can take the following forms:

If not specified, any certificate trusted by the machine is accepted.

Certificates are validated as trusted by the machine based on the System's trust store. The trust store used is the 'javax.net.ssl.trustStore' value specified for the system. If no value is specified for this property, Java's default trust store is used (for example, JAVA_HOME\lib\security\cacerts).

Use '*' to signify to accept all certificates. Note that this is not recommended due to security concerns.

Schema

This section provides a complete list of schema properties you can configure.

Location

Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path.

Data Type

string

Default Value

%APPDATA%\SSAS Data Provider\Schema

Remarks

The Location property is only needed if you want to either customize definitions (for example, change a column name, ignore a column, etc.) or extend the data model with new tables, views, or stored procedures.

If left unspecified, the default location is %APPDATA%\SSAS Data Provider\Schema, where %APPDATA% is set to the user's configuration directory:

BrowsableSchemas

Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.

Data Type

string

Default Value

""

Remarks

Listing all available database schemas can take extra time, thus degrading performance. Providing a list of schemas in the connection string saves time and improves performance.

Tables

Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC.

Data Type

string

Default Value

""

Remarks

Listing all available tables from some databases can take extra time, thus degrading performance. Providing a list of tables in the connection string saves time and improves performance.

If there are lots of tables available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those tables. To do this, specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.

Views

Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.

Data Type

string

Default Value

""

Remarks

Listing all available views from some databases can take extra time, thus degrading performance. Providing a list of views in the connection string saves time and improves performance.

If there are lots of views available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those views. To do this, specify the views you want in a comma-separated list. Each view should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.

Miscellaneous

This section provides a complete list of miscellaneous properties you can configure.

Catalog

The Analysis Services catalog to use. This may also be known as a Database from within Analysis Services.

Data Type

string

Default Value

""

Remarks

This input is optional as catalogs will be displayed by default. However, if if you have UseMDX set to true, this value will ensure the MDX queries are submitted to the correct catalog.

CustomHeaders

Specifies additional HTTP headers to append to the request headers created from other properties, such as ContentType and From. Use this property to customize requests for specialized or nonstandard APIs.

Data Type

string

Default Value

""

Remarks

Use this property to add custom headers to HTTP requests sent by the connector.

This property is useful when fine-tuning requests to interact with APIs that require additional or nonstandard headers. Headers must follow the format "header: value" as described in the HTTP specifications and each header line must be separated by the carriage return and line feed (CRLF) characters. Important: Use caution when setting this property. Supplying invalid headers may cause HTTP requests to fail.

ExposeMemberKeys

Determines if each level should be converted into a measure, allowing calculations to be performed on the measure.

Data Type

bool

Default Value

false

Remarks

By default, all levels are of type String. Enabling this option allows a level to be resolved down to its key property, creating a measure that has the level's DBType data type. Calculations can then be performed on the measure.

ExpressionInDescription

Set this to true to report expressions as part of the description on measure columns.

Data Type

bool

Default Value

false

Remarks

The connector reports the remarks for several types of entities (dimensions, measures, measure groups and heirarchies) as table and column descriptions. By default, the connector will include only the remarks in measure column descriptions.

If this option is enabled, then the measure expression is included in the measure column description, along with the remarks. The descriptions on other types of entities are not affected.

ExtraProperties

Additional properties to submit on each MDX request to Microsoft SQL Server Analysis Services.

Data Type

string

Default Value

""

Remarks

When setting UseMDX to true, properties may be specified using this connection property to fill out extra values in the PropertiesList of the XMLA request. Use name=value pairs separated by a semicolon to submit the properties. For example, Catalog=MyCatalog;Cube=MyCube;.

A list of properties may be found by executing SELECT * FROM $System.DISCOVER_PROPERTIES.

IncludeJoinColumns

Set this to true to include extra join columns on each table.

Data Type

bool

Default Value

false

Remarks

Some tools may require an ON condition (or generate them automatically) based on foreign key references. By setting IncludeJoinColumns to true, every table will include a foreign key reference to the other tables. These columns will not return any data and are not useful for anything other than passing as ON conditions to perform joins upon.

In Microsoft SQL Server Analysis Services, the dimensions and measures making up the tables are already related naturally. There is no context on which to join them provided. Therefore, the Jitterbit Connector for Microsoft SQL Server Analysis Services supports joining without specifying an ON condition, so they are optional to specify.

MaxRows

Specifies the maximum rows returned for queries without aggregation or GROUP BY.

Data Type

int

Default Value

-1

Remarks

This property sets an upper limit on the number of rows the connector returns for queries that do not include aggregation or GROUP BY clauses. This limit ensures that queries do not return excessively large result sets by default.

When a query includes a LIMIT clause, the value specified in the query takes precedence over the MaxRows setting. If MaxRows is set to "-1", no row limit is enforced unless a LIMIT clause is explicitly included in the query.

This property is useful for optimizing performance and preventing excessive resource consumption when executing queries that could otherwise return very large datasets.

Other

Specifies additional hidden properties for specific use cases. These are not required for typical provider functionality. Use a semicolon-separated list to define multiple properties.

Data Type

string

Default Value

""

Remarks

This property allows advanced users to configure hidden properties for specialized scenarios. These settings are not required for normal use cases but can address unique requirements or provide additional functionality. Multiple properties can be defined in a semicolon-separated list.

Specify multiple properties in a semicolon-separated list.

Integration and Formatting

ResponseRowLimit

The number of response rows to allow before erroring. Set to 0 for no limit.

Data Type

int

Default Value

100000

Remarks

Selecting a lot of columns results in a number of crossjoins occurring under the hood when translated to something that is acceptable for Microsoft SQL Server Analysis Services. This is not intuitive if you are not familiar with MDX. It can easily result in very large responses that time out. The ResponseRowLimit is designed to try and alert the user to understand what can be very expensive requests.

ShowHiddenEntities

Set this to true to include hidden dimensions, measures and levels.

Data Type

bool

Default Value

false

Remarks

By default the connector does not report entities that Microsoft SQL Server Analysis Services marks as hidden. Enabling this option allows you to query them.

SplitMeasures

Set this to true to split Measures table into individual tables.

Data Type

bool

Default Value

false

Remarks

All measures are currently grouped into a single table 'Measures'. Set this to true to split Measures table into individual tables (if a table only contains measures) and include measures into respective dimensions tables.

SplitMeasuresOn

Use this property in conjunction with SplitMeasures to set the priority for how measures should be organized into tables.

Data Type

string

Default Value

MeasureGroup

Remarks

This property controls the order in which measure storage attributes are used to sort them into subtables when SplitMeasures is true. Provide a comma-delimited list of storage methods in the order they should be prioritized. Available values are:

• MeasureGroup
• DisplayFolder

Split-Measure tables will be named according to whichever attribute comes first in the list, or sorted into a generic 'Measures' table if none of the values in the list are populated for the measure.

Timeout

Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout.

Data Type

int

Default Value

60

Remarks

This property controls the maximum time, in seconds, that the connector waits for an operation to complete before canceling it. If the timeout period expires before the operation finishes, the connector cancels the operation and throws an exception.

The timeout applies to each individual communication with the server rather than the entire query or operation. For example, a query could continue running beyond the timeout value if each paging call completes within the timeout limit.

Setting this property to 0 disables the timeout, allowing operations to run indefinitely until they succeed or fail due to other conditions such as server-side timeouts, network interruptions, or resource limits on the server. Use this property cautiously to avoid long-running operations that could degrade performance or result in unresponsive behavior.

UseMDX

Set this to true to pass MDX queries to Microsoft SQL Server Analysis Services as-is.

Data Type

bool

Default Value

false

Remarks

You can execute SQL-92 SELECT queries to the views modeled by the connector; set this property to instead execute MDX queries directly to Microsoft SQL Server Analysis Services. If you are using MDX queries directly, it is recommended to also specify the Catalog to ensure MDX queries are submitted to the correct catalog.

See Retrieving Analysis Services Data for more information on querying Microsoft SQL Server Analysis Services through the connector.

UserDefinedViews

Specifies a filepath to a JSON configuration file defining custom views. The provider automatically detects and uses the views specified in this file.

Data Type

string

Default Value

""

Remarks

This property allows you to define and manage custom views through a JSON-formatted configuration file called UserDefinedViews.json. These views are automatically recognized by the connector and enable you to execute custom SQL queries as if they were standard database views. The JSON file defines each view as a root element with a child element called "query", which contains the SQL query for the view. For example:

{
    "MyView": {
        "query": "SELECT * FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer WHERE MyColumn = 'value'"
    },
    "MyView2": {
        "query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
    }

}

You can define multiple views in a single file and specify the filepath using this property. For example: UserDefinedViews=C:\Path\To\UserDefinedViews.json. When you use this property, only the specified views are seen by the connector.

Refer to User Defined Views for more information.
