You want to do something like...

CREATE OR REPLACE TRIGGER CheckEname
BEFORE UPDATE OF ename ON Emp_Tab
...

You could also optionally include a WHEN clause to further restrict the firing of the trigger on that column if you're going to be dealing with a row-level trigger.

HI,
Can anyone tell me how a trigger is written to fire only when a specific column value in a table has changed.

Thanks
Kirtee
