Important

Data mining was deprecated in SQL Server 2017 Analysis Services and now discontinued in SQL Server 2022 Analysis Services. Documentation is not updated for deprecated and discontinued features. To learn more, see Analysis Services backward compatibility.

For all models that support drillthrough, you can retrieve case data and structure data by creating a DMX query in SQL Server Management Studio or any other client that supports DMX.

Warning

To view the data, drillthrough must have been enabled, and you must have the necessary permissions.

Specifying Drillthrough Options

The general syntax is for retrieving model cases and structure cases is as follows:

SELECT <model column list>, StructureColumn('<structure column name') FROM <modelname>.CASES

For additional information about using DMX queries to return case data, see SELECT FROM <model>.CASES (DMX) and SELECT FROM <structure>.CASES.

Examples

The following DMX query returns the case data for a specific product series, from a time series model. The query also returns the column Amount, which was not used in the model but is available in the mining structure.

SELECT [DateSeries], [Model Region], Quantity, StructureColumn('Amount') AS [M200 Pacific Amount]  
FROM Forecasting.CASES  
WHERE [Model Region] = 'M200 Pacific'

Note that in this example, an alias has been used to rename the structure column. If you do not assign an alias to the structure column, the column is returned with the name 'Expression'. This is the default behavior for all unnamed columns.
