3.4.1.6 Table Constraints Pane

Specifies one or more check constraints for the table.

A check constraint specifies a condition that must be met when a row is inserted into the table or when an existing row is modified.

• Name: Name of the check constraint definition.

• Check Condition: Condition that must be met for a row to fulfil the check constraint. You can use any valid CHECK clause (without the CHECK keyword). For example, to indicate that the value in a numeric column named RATING must be from 1 to 10, you can specify rating >=1 and rating <= 10.

• Enabled: If this option is checked, the check constraint is enforced.
