Setting or Changing Field-Level or Table Rules
You can set new field-level or table rule expressions and rule text, as well as alter rules and text you established with CREATE TABLE or ALTER TABLE commands.
To change an existing rule
In the Table Designer, select the Table tab and enter the new rule expression or rule text in the Rule and Message boxes in the Record validation section.

Use the ALTER TABLE command.
To view the current rule expression and associated text, you can use the DBGETPROP( ) function; these values are read-only for tables and can only be changed using the ALTER TABLE command.
