Foreign Keys Page

•

The Columns page can be considered the primary page of Table Editor just as columns and rows are central to tables. The following image shows the Columns page of Table Editor. The table below the image describes the GUI objects. Click an area of the image for which you want more information.

See also Columns Tasks for the tasks that you perform on the page.

The Indexes page allows you to add and delete indexes. The Indexes page is explained within the context of the tasks that you perform for indexes. See Indexes Tasks.

Foreign Keys Page

The Foreign Keys page allows you to add and delete foreign keys. The Foreign Keys page is explained within the context of the tasks that you perform for foreign keys. See Foreign Keys Tasks.

The SQL View page displays, and allows you to copy, the SQL statements used to create or alter the table. The CREATE TABLE panel displays the SQL with which you could create the same table. The ALTER TABLE panel reflects any editing changes to an existing table that you make with Table Editor. When you save the table changes, the ALTER TABLE panel is cleared and the ALTER statement(s) becomes part of the CREATE TABLE statement.

The SQL View page is further explained within the context of the tasks that you can perform. See SQL View Tasks.
