SQL 11028
11028 Action statement of trigger trigger-name on table
subject-table-name has failed.
Cause. The execution of a trigger action statement failed.
Effect. The operation fails.
Recovery. This error message will appear with another error message that states
what statement has failed, why it failed, and how to recover.
SQL 11029
11029 Attempt to change the value of column column-name of a
given row more than once in the same statement.
Where column-name is the name of the column.
Note. As of the ABU SPR, this message is no longer generated.
Cause. You attempted to change a column of a particular row from a particular table to
two different values at two different instances. You have designed a set of triggers that
can result in nondeterministic behavior.
Effect. The operation fails.
Recovery. None. Redesign the triggers in such a way that this condition is not raised.
This usually involves following the cascading of triggers and identifying when the
column is being modified more than once. From error 11028, which was raised along
with this error, you can identify the trigger that made the second change to the same
column of a given row.
SQL 11030
11030 Trigger does not exist.
Cause. You attempted to drop or alter a trigger that does not exist.
Effect. The operation fails.
Recovery. None, if the name of the trigger was entered correctly. Otherwise, correct
the trigger name and resubmit.
