Specifies that SQL inserts the SQLDA2 into the program. The
    SQLDA2, like the SQLDA, is a collection of variables that
    provides information about dynamic SQL statements to the program
    and information about host language variables in the program to
    SQL. You should use the SQLDA2 in any dynamic statement where the
    column name used in a parameter marker or select list item is one
    of the date-time or interval data types.

    For more information on the SQLDA and SQLDA2, see the Oracle Rdb
    SQL Reference Manual.
