1  –  connection-name

    Specifies a name for the association between the group of
    databases being attached (the environment) and the database and
    request handles that reference them (the connection).

    You can specify the connection name as the following:

    o  String literal enclosed within single quotation marks

    o  Parameter (in module language)

    o  Variable (in precompiled SQL)

2  –  DEFAULT

    Specifies one or more databases to be attached as a unit.

    Use the DEFAULT keyword to specify the default connection.
    The default connection is all the databases that were attached
    interactively, or all those made known to the module at compile
    time through DECLARE ALIAS statements.
