Controls whether double quotation marks are interpreted as string
    literals or delimited identifiers. If you specify SQLV40, SQL
    interprets double quotation marks as literals. All other dialects
    interpret double quotation marks as delimited identifiers. The
    default is SQLV40.

    Use the QUOTING RULES clause, rather than the SQLOPTIONS = ANSI_
    QUOTING qualifier because the qualifier will be deprecated in a
    future release.
