Creates a result set for a table, which is the column list for the specified table or tables. When you request columns for a PUBLIC synonym, you must have set the SYNONYMCOLUMNS connection attribute and specified an empty string as the szTableOwner argument. When returning columns for PUBLIC synonyms, the driver sets the TABLE NAME column to an empty string. The result set contains an additional column, ORDINAL POSITION, at the end of each row. This value is the ordinal position of the column in the table.
