Example 1

    The following example deletes a single constraint definition:

    INVOKE DATABASE PATHNAME 'PERSONNEL'
    DELETE CONSTRAINT EMP_NUM_CON.

    This statement deletes EMP_NUM_CON from the physical database and
    the data dictionary.

    Example 2

    You can also delete more than one constraint definition at once:

    INVOKE DATABASE FILENAME 'PERSONNEL'
    DELETE CONSTRAINT SAL_CON,SS_NUM_CON.

    This statement deletes the two constraint definitions from the
    physical database.
