Syntax options:

       FLAGGER ON
       FLAGGER SQL89
       FLAGGER SQL92_ENTRY
       FLAGGER MIA

    Controls the output of informational messages that indicate
    nonstandard syntax, that is, extensions to the ANSI/ISO standard
    syntax or the MIA standard syntax.

    If you specify SET FLAGGER ON, which is the same as specifying
    SET FLAGGER SQL92_ENTRY ON, SQL sends you an informational
    message if you issue a subsequent interactive SQL statement that
    contains syntax that is an extension to the ANSI/ISO standard.

    If you specify SET FLAGGER MIA ON, SQL sends you an informational
    message if you issue a subsequent interactive SQL statement that
    contains syntax that is an extension to the MIA standard.

    The flaggers are independent of each other and any combination of
    flaggers can be set at one time.

    The default is FLAGGER OFF if you do not explicitly set a flagger
    on.
