Replace a Table or a Named Query in a Data Source View (Analysis Services)

  • Άρθρο

Applies to: SQL Server Analysis Services Azure Analysis Services Fabric/Power BI Premium

In Data Source View Designer, you can replace a table, view, or named query in a data source view (DSV) with a different table or view from the same or a different data source, or with a named query defined in the DSV. When you replace a table, all other objects in an SQL Server Analysis Services database or project that have references to the table continue to reference the table because the object ID for the table in the DSV does not change. Any relationships that are still relevant (based on name and column-type matching) are retained. In contrast, if you delete and then add a table, references and relationships are lost and must be recreated.

To replace a table with another table, you must have an active connection to the source data in Data Source View Designer in project mode.

You most frequently replace a table in the data source view with another table in the data source. However, you can also replace a named query with a table. For example, you previously replaced a table with a named query, and now want to revert to a table.

Important

If you rename a table in a data source, follow the steps for replacing a table and specify the renamed table as the source of the corresponding table in the DSV before you refresh a DSV. Completing the replacement and renaming process preserves the table, the table's references, and the table's relationships in the DSV. Otherwise, when you refresh the DSV, a renamed table in data source is interpreted as being deleted. For more information, see Refresh the Schema in a Data Source View (Analysis Services).

Replace a table with a named query

  2. In Solution Explorer, expand the Data Source Views folder, and then double-click the data source view.

  3. Open the Create Named Query dialog box. In either Tables or Diagram pane, right-click the table that you wish to replace, point to Replace Table and then click With New Named Query.

  4. In the Create Named Query dialog box, define the named query and then click OK.

  5. Save the modified data source view.
