How to: Add, View, Modify, or Delete a Named Calculation to a Table Using Data Source View Designer

Updated: 14 April 2006

Both Microsoft SQL Server 2005 Analysis Services (SSAS) and SQL Server 2005 Integration Services (SSIS) projects can include data source views, and both support the ability to add named calculations to a table.

  1. In Business Intelligence Development Studio, open the project or connect to the database that contains the data source view in which you wish to define a named calculation.

  2. In Solution Explorer, expand the Data Source Views folder, then open the data source view in Data Source View Designer by doing one of the following:

    • Double-click the data source view.
    • Right-click the data source view and click Open.
    • Click the data source view and then on the View menu, click Open.
  3. Open the Create Named Calculation dialog box by doing one of the following:

    • Right-click the table in which you wish to define the named calculation in either the Tables or the Diagram pane, and then click New Named Calculation.
    • Click the table in which you wish to define the named calculation in either the Tables or the Diagram pane, and then click New Named Calculation on the Data Source View Designer toolbar.
    • Click the table in which you wish to define the named calculation in either the Tables or the Diagram pane, and then click New Named Calculation on the Data Source View menu.

To locate a table or view, you can use the Find Table option by either clicking the Data Source View menu or right-clicking in an open area of the Tables or Diagram panes. For more information, see How to: View Objects in a Data Source View Using Data Source View Designer.

  1. In the Create Named Calculations dialog box, do the following:
    • In the Column name text box, type the name of the new column.

    • On the File menu, click Save Selected Items or Save All.
    • On the Data Source View Designer toolbar, click Save Selected Items or Save All.
    • Close the Data Source View Designer in Business Intelligence Development Studio and then click Save when prompted.
