A user-defined SQLDA group variable that the OpenESQL preprocessor did not recognize was specified for compilation from the
Visual Studio IDE. This is usually due to a variable defined with COMP instead of COMP-5.
Resolution:
Recompile specifying the SQL(USER-SQLDA=option) directive, where
option can be NONE, ANSI, or MAINFRAME. See the
USER-SQLDA topic for details.
