I have a table that gets updated thru a cursor using tableupdate(). The table cannot have null values in 2 columns. If the cursor tries to add a blank record to the table, I can trap the error and do a TableRevert(). The problem is - it reverts back changes to all the records and not just the problem record as son as it encounters a problem. How can I ensure it will update all the good changes and discard only the invalid records ?
