There may be exceptional cases where you want to allow an error encountered by the Message Agent when applying SQL statements to go unreported. This may arise when you know the conditions under which the error occurs and are sure that it does not produce inconsistent data and that its consequences can safely be ignored.
To allow errors to go unreported, you can create a BEFORE trigger on the action that causes the known error. The trigger should signal the REMOTE_STATEMENT_FAILED SQLSTATE (5RW09) or SQLCODE (-288) value.
For example, if you want to quietly fail INSERT statements on a table that fail because of a missing referenced column, you could create a BEFORE INSERT trigger that signals the REMOTE_STATEMENT_FAILED SQLSTATE when the referenced column does not exist. The INSERT statement fails, but the failure is not reported in the Message Agent log.
