Select a Nested Table Key Column Dialog Box (Mining Structure View)

Use the Select a Nested Table Key Column dialog box to designate a column that will act as the key for the new nested table. When you exit the dialog box, a new table is added to the mining structure that contains the designated key column. You can add additional columns to the nested table by right-clicking the structure and selecting Add a Column. The dialog box contains different options depending on whether you are working with an OLAP mining model or a relational mining model.

Options

    This is only used for relational mining models.

  • Source column

  • Show column types
