Working with table and column constraints in Sybase Central

In Sybase Central, you add, alter, and drop column constraints on the Constraints tab of the table or column property sheet.

To manage constraints

1. Open the Tables folder.

2. In the right pane, double-click the table you want to alter.

3. On the Constraints tab, make the appropriate changes to the constraint you want to modify.

   For example, to add a table or column constraint, click the Constraints tab and choose File > New > Table Check Constraint or File > New > Column Check Constraint.
