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

    The connection name must be unique within your application. Use
    a literal string enclosed within single quotation marks, for
    example:

    CONNECT TO 'ALIAS CORP FILENAME corporate_data' AS 'JULY_CORP_DATA'

    If you do not specify a connection name, SQL generates a unique
    connection name. For example:

    SQL> CONNECT TO
    cont> 'ATTACH FILENAME mf_personnel';
    SQL> SHOW CONNECTIONS
            RDB$DEFAULT_CONNECTION
    ->      SQL$CONN_00000000
