Purpose

Displays the attributes for a specific named constraint on a table. Use the SHOW TABLE statement to obtain unnamed constraint information. See “SHOW object.”

The HELP CONSTRAINT statement does not report information for row-level security constraints. Specify the CONSTRAINT option with a HELP SESSION request to report the constraint values associated with a session.

Privileges

You must own the table in which the constraint is defined or have at least one privilege on that table.

Use the SHOW privilege to enable a user to perform HELP or SHOW requests only against a specified constraint.
