    The attributes shown in this section are based upon and supersede the corresponding older attributes, Group Name, from-sql, and to-sql, while providing additional functionality.

    The older attributes are retained for compatibility with existing applications.

    The from-sql Database and to-sql Database attributes identify the database that contains the external routine that performs the transform function.

    The system returns this set of attributes for each column in the HELP TABLE.
