sql_implementation_info
   The table sql_implementation_info contains
   information about various aspects that are left
   implementation-defined by the SQL standard.  This information is
   primarily intended for use in the context of the ODBC interface;
   users of other interfaces will probably find this information to be
   of little use.  For this reason, the individual implementation
   information items are not described here; you will find them in the
   description of the ODBC interface.
