Hi,

I am trying to create this trigger that is updating the time and data in a table when a flag is changed in another table. This is the trigger.

The erros is : This statemens is not allowed.

Any ideas how can i make it work?

Thanks.
CREATE TRIGGER name
 

	BEFORE UPDATE ON table
 

	REFERENCING OLD AS OLDVAL 
 

	NEW AS NEWVAL 
 

	FOR EACH ROW 
 

	MODE DB2SQL 
 

	
 

	when (OLDVAL.flag != NEWVAL.flag )
 

		UPDATE other_table
 

				SET (FEADAT,FEATIM) = (CURRENT DATE, SUBSTR(CAST(current time AS CHAR(8)),1,2) ||  SUBSTR(CAST(current time AS CHAR(8)),4,2) )
 

					WHERE other_table.id =NEWVAL.id ;

Hi se,

I believe that this kind of trigger needs to be an AFTER trigger.

I agree with Kent. It should be an AFTER trigger.

Also, I think you need a BEGIN and END.

e.g.
 create trigger TR_MyTableAfterUpdate

   after update of flag on MyTable

   referencing new row as NewRow

               old row as OldRow

   for each row

   set option dbgview = *source

 Begin

    update SomeOtherTable s

    .... < some stuff >

    ;

 End;
