Creating Self-Joins Automatically

Creating Self-Joins Automatically

If a table has a reflexive relationship in the database, you can join it to itself automatically.

To create a self-join automatically

1. Add to the Diagram pane the table you want to work with.
   
   
2. Add the same table again, so that the Diagram pane shows the same table twice within the Diagram pane.
   The Query Designer assigns an alias to the second instance by adding a sequential number to the table name. In addition, the Query Designer creates a join line between the two rectangles representing the two different ways the table participates in the query.
