Specifies a collating sequence for the named domain.

    The OpenVMS National Character Set (NCS) utility provides a
    set of predefined collating sequences and also lets you define
    collating sequences of your own. The COLLATING SEQUENCE clause
    accepts both predefined and user-defined NCS collating sequences.

    Before you use the COLLATING SEQUENCE clause in a CREATE DOMAIN
    statement, you must first specify the NCS collating sequence for
    SQL using the CREATE COLLATING SEQUENCE statement. The sequence-
    name argument in the COLLATING SEQUENCE clause must be the same
    as the sequence-name in the CREATE COLLATING SEQUENCE statement.
