Define Index Membership for an Oracle Column

In a model based on the Oracle target server, you use the Indexes tab in the Table Column Editor to define index membership for the selected column.

To define index membership for an Oracle column

  1. Right-click a column in the Model Explorer and click Properties.

    The Oracle Table Column Editor opens.

  2. Select the table from the Table drop-down that contains the column for which you want to define index membership.
  3. Select the column in the Navigation Grid that you want to define.

    Note: Click New New icon in property editors to create a new object on the toolbar to create a new column. Use the Enter filter text box to filter a very large list of columns to quickly locate the one that you want to define.

  4. Click the Indexes tab and work with the following options:
    Index Membership

    Displays the list of indexes that are attached to the current table. Selected items in this list show the primary key, alternate key, foreign key, and inversion entry indexes of which the selected column is a member. Select the check box next to an index name to assign the selected column to that index. Clear the check box next to an index name to remove the column from the index. Use the following options on the toolbar to work with this list:

    Table Index Editor Toolbar_Index Sort Order Button Sort

    Sorts the indexes by alphabetic, reverse alphabetic, or index order. You select the method you want using the drop-down menu that opens after you click the Sort button. Visual cues are provided for how the index list is currently sorted:

    Specifies that the index list is sorted in alphabetic order.

    Property editor Reverse Alpha Sort Button

    Specifies that the index list is sorted in reverse alphabetic order.

    Table Index Editor Toolbar_Index Sort Order Button

  5. Click Close.

    Index membership for the column is defined and the Oracle Table Column Editor closes.
