I have created the below trigger in Oracle to ensure that a value in a table remains at 180 but I need to restrict this to one row in this table. Is there a way to use an IF statement or a where clause of some type for a particular row in that table? The Row is called ADMIN. Triggers weren't covered in my course so only know a few basic statements.


CREATE OR REPLACE
TRIGGER DAYSAGO_trg
BEFORE UPDATE ON days_ago
FOR EACH ROW
BEGIN
:NEW.days_ago := 180;

END;

Any help or pointers would be greatly appreciated.

try (just a guess)

...
FOR EACH ROW
when new.mycol = 'ADMIN'
BEGIN
...

==========================================
Cursors are useful if you don't know sql.
SSIS can be used in a similar way.
