Oracle Editors - Members Tab

The Members tab is used in the Oracle Index Editor for Tables and the Oracle Index Editor for Materialized Views. Use the Members tab to select columns within a table or materialized view and assign them to an index. Key groups that you create in a logical model become indexes in a physical model. By default, the columns in each foreign key index include all of the columns that are migrated from the same table or materialized view. If a table or materialized view includes foreign key columns from two different parent tables or parent materialized views, two foreign key indexes are created, one for each parent table or materialized view.

The following describes the options for the Members tab:

Available Columns

Lists all of the columns in the table or materialized view that are not members of the selected index. To move a column to the Index Members list, either double-click a column in this list or select a column and click the button.

Index Members

Lists all of the columns in the table or materialized view that are members of the selected index. To move a column to the Available Columns list, either double-click a column in this list or select a column and click the button. You can move a selected column in the Index Members list up one position by clicking on the button. This button will not be available if the selected column is already at the top of the list. To move a selected column down one position, click the button. This button will not be available if the selected column is already at the bottom of the list.

Sort Type

Click within a field in this column to get a drop-down where you can select either Ascending or Descending as the sort type.
