What Is The Difference Between Item Error () And Db Error ()? |
|
Answer» ITEM Error () occurs when the data supplied to a particular column in a table fails some validation rules. For example a DW column designed to ACCEPT only integer values throws this error if a string VALUE is passed. DB Error () occurs when INSERT/UPDATE/DELETE/RETRIEVE fails. When it occurs, the DW Control throws up a message box DESCRIBING the error to the DBMS. The user can also get the appropriate error code and THROW up message boxes.
