You can use the ALTER TABLE statement to add a security constraint column, for example:
ALTER TABLE table_name ADD constraint_name CONSTRAINT ;
where:
| Syntax Element | Description |
|---|---|
| constraint_name | Specifies an existing CONSTRAINT object name.
You cannot add a security constraint column to a table with a hash index or join index.
|
| CONSTRAINT | The CONSTRAINT keyword identifies the constraint_name as an existing constraint object. |
