Hi all,
I try to make a simple triger with PL/pgSQL.
It starts on update and in my table I have a field mname varchar(20).
How can I compare if the new and the old value for this field are the same.
I tryed: if NEW.mname <> OLD.mNAME THEN ....
but it is not working !
Exist any deteilet documentation about the PL/pgSQL.
Many thanks.
