You can modify a minischema by removing tables or joins from it.
You can follow the dialog box-based procedure described in Adding or Removing Tables in a Minischema to remove tables from a minischema. Or, you can use the process described below to remove tables or selected joins.
Note: | When you want to remove a minischema table that has user-defined joins, Oracle recommends that you always delete those joins first, then delete the minischema table. |
To remove tables or joins from a minischema:
If not already opened, open the minischema (see Opening a Minischema).
Optional: In the minischema work area, right-click the table object you want to remove and select Remove.
Repeat this step for all tables you want to remove.
Optional: To remove a join, right-click the join in the minischema work area and select Remove.
Repeat this step for all joins you want to remove.
To save the minischema, right-click in the minischema work area and select Save Minischema.
