EndPoint Execute a DAX query

Name

execute_dax_query

Description

Executes a DAX query on a Dataset in a default or specified Workspace. [API reference]

Parameters

Parameter Label Required Options Description
Query DAX query YES Your DAX Query. Examples: EVALUATE FILTER('MyTable',true) --OR-- more complex EVALUATE FILTER(''MyTable'', [SomeNameColumn] = "ZZZ" && ([SomeIdColumn] = 10643 || [SomeIdColumn] = 10952 ) )
DatasetId DatasetId NO
WorkspaceId WorkspaceId NO
Option Value
Default

Output Columns

Label Data Type (SSIS) Data Type (SQL) Length Raw Description
There are no Static columns defined for this endpoint. This endpoint detects columns dynamically at runtime.

Input Columns

Label Data Type (SSIS) Data Type (SQL) Length Raw Description
There are no Static columns defined for this endpoint. This endpoint detects columns dynamically at runtime.

Examples

SSIS

Use Power BI Connector in API Source component to read data or in API Destination component to read/write data:

Execute a DAX query using API Source

Power BI
Execute a DAX query
SSIS API Source - Read from table or endpoint

Execute a DAX query using API Destination

Power BI
Execute a DAX query
SSIS API Destination - Access table or endpoint

ODBC application

Use these SQL queries in your ODBC application data source:
