   2  * Description: This module contains functions for setting the data
   3  *              for individual fields (TupleField structure) of a
   4  *              manual result set.
   5  *
   6  * Important Note: These functions are ONLY used in building manual
   7  *              result sets for info functions (SQLTables,
   8  *              SQLColumns, etc.)
