Microsoft SSAS Connection Details
Introduction
Connector Version
This documentation is based on version 23.0.8703 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
Use Kerberos
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 Cerberos Credential Cache Files:
- Ensure that the
KRB5CCNAME
variable is present in your environment. - 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. -
To obtain a ticket:
- Open the MIT Kerberos Ticket Manager application.
- Click
Get Ticket
. - Enter your principal name and password.
- 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.
Note
If you would prefer not to edit KRB5CCNAME
, you can use the KerberosTicketCache
property to set the file path manually. After this is set, the connector uses the specified 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 ifUseMDX
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.
Advanced Features
This section details a selection of advanced features of the Microsoft SQL Server Analysis Services connector.
User Defined Views
The connector allows you to define virtual tables, called user defined views, whose contents are decided by a pre-configured query. These views are useful when you cannot directly control queries being issued to the drivers. See User Defined Views for an overview of creating and configuring custom views.
SSL Configuration
Use SSL Configuration to adjust how connector handles TLS/SSL certificate negotiations. You can choose from various certificate formats; see the SSLServerCert
property under "Connection String Options" for more information.
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).
See Query Processing for more information.
User Defined Views
The Jitterbit Connector for Microsoft SQL Server Analysis Services allows you to define a virtual table whose contents are decided by a pre-configured query. These are called User Defined Views, which are useful in situations where you cannot directly control the query being issued to the driver, e.g. when using the driver from Jitterbit. The User Defined Views can be used 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 as follows:
- Each root element defines the name of a view.
- Each root element contains 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
User Defined Views are exposed in the UserViews
schema by default. This is done to avoid the view's name clashing with an actual entity in the data model. You can change the name of the schema used for UserViews by setting 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 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 to do so.
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.

If Kerberos KDC 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 KDC 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 propertiesjava.security.krb5.realm
andjava.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 configured domain name and host.

Designations of certificate stores are platform-dependent.
The following are designations of the most common User and Machine certificate stores in Windows:
Property | Description |
---|---|
MY | A certificate store holding personal certificates with their associated private keys. |
CA | Certifying authority certificates. |
ROOT | Root certificates. |
SPC | Software publisher certificates. |
In Java, the certificate store normally is a file containing certificates and optional private keys.
When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (for example, PKCS12 certificate store).

SSLServerCert
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:
Description | Example |

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.
Property | Description |
---|---|
Location | A path to the directory that contains the schema files defining tables, views, and stored procedures. |
BrowsableSchemas | This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA, SchemaB, SchemaC. |
Tables | This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA, TableB, TableC. |
Views | Restricts the views reported to a subset of the available tables. For example, Views=ViewA, ViewB, ViewC. |
Location
A path to the directory that contains the schema files defining tables, views, and stored procedures.
Data Type
string
Default Value
%APPDATA%\SSAS Data Provider\Schema
Remarks
The path to a directory which contains the schema files for the connector (.rsd files for tables and views, .rsb files for stored procedures). The folder location can be a relative path from the location of the executable. The Location
property is only needed if you want to customize definitions (for example, change a column name, ignore a column, and so on) or extend the data model with new tables, views, or stored procedures.
If left unspecified, the default location is "%APPDATA%\SSAS Data Provider\Schema" with %APPDATA%
being set to the user's configuration directory:
Platform | %APPDATA% |
---|---|
Windows | The value of the APPDATA environment variable |
Mac | ~/Library/Application Support |
Linux | ~/.config |
BrowsableSchemas
This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.
Data Type
string
Default Value
""
Remarks
Listing the schemas from databases can be expensive. Providing a list of schemas in the connection string improves the performance.
Tables
This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC.
Data Type
string
Default Value
""
Remarks
Listing the tables from some databases can be expensive. Providing a list of tables in the connection string improves the performance of the connector.
This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.
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`.
Note that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.
Views
Restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.
Data Type
string
Default Value
""
Remarks
Listing the views from some databases can be expensive. Providing a list of views in the connection string improves the performance of the connector.
This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.
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`.
Note that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.
Miscellaneous
This section provides a complete list of miscellaneous properties you can configure.
Property | Description |
---|---|
Catalog | The Analysis Services catalog to use. This may also be known as a Database from within Analysis Services. |
CustomHeaders | Other headers as determined by the user (optional). |
ExpressionInDescription | Set this to true to report expressions as part of the description on measure columns. |
ExtraProperties | Additional properties to submit on each MDX request to Microsoft SQL Server Analysis Services. |
IncludeJoinColumns | Set this to true to include extra join columns on each table. |
MaxRows | Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses. |
Other | These hidden properties are used only in specific use cases. |
ResponseRowLimit | The number of response rows to allow before erroring. Set to 0 for no limit. |
ShowHiddenEntities | Set this to true to include hidden dimensions, measures and levels. |
SplitMeasures | Set this to true to split Measures table into individual tables. |
Timeout | The value in seconds until the timeout error is thrown, canceling the operation. |
UseMDX | Set this to true to pass MDX queries to Microsoft SQL Server Analysis Services as-is. |
UserDefinedViews | A filepath pointing to the JSON configuration file containing your custom views. |
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
Other headers as determined by the user (optional).
Data Type
string
Default Value
""
Remarks
This property can be set to a string of headers to be appended to the HTTP request headers created from other properties, like ContentType, From, and so on.
The headers must be of the format "header: value" as described in the HTTP specifications. Header lines should be separated by the carriage return and line feed (CRLF) characters.
Use this property with caution. If this property contains invalid headers, HTTP requests may fail.
This property is useful for fine-tuning the functionality of the connector to integrate with specialized or nonstandard APIs.
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
Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.
Data Type
int
Default Value
-1
Remarks
Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.
Other
These hidden properties are used only in specific use cases.
Data Type
string
Default Value
""
Remarks
The properties listed below are available for specific use cases. Normal driver use cases and functionality should not require these properties.
Specify multiple properties in a semicolon-separated list.
Integration and Formatting
Property | Description |
---|---|
DefaultColumnSize | Sets the default length of string fields when the data source does not provide column length in the metadata. The default value is 2000. |
ConvertDateTimeToGMT | Determines whether to convert date-time values to GMT, instead of the local time of the machine. |
RecordToFile=filename | Records the underlying socket data transfer to the specified file. |
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.
Timeout
The value in seconds until the timeout error is thrown, canceling the operation.
Data Type
int
Default Value
60
Remarks
If Timeout
= 0, operations do not time out. The operations run until they complete successfully or until they encounter an error condition.
If Timeout
expires and the operation is not yet complete, the connector throws an exception.
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
A filepath pointing to the JSON configuration file containing your custom views.
Data Type
string
Default Value
""
Remarks
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 as follows:
- Each root element defines the name of a view.
- Each root element contains 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"
