Thread: Metadata from NEW and OLD constructs?

Greetings,

I was wondering if it's possible to get any of the metadata from the NEW and OLD constructs in a trigger or view rule?  Specifically, I'd like to get the column name or identifier anywhere the new record differs from the old record (i.e. NEW.column_X <> OLD.column_X).  Any advice would be greatly appreciated.

Thanks,
JL

If your trigger is written in C, definitly. If the trigger is in
pl/pgsql, no. For other languages I don't know. which language are you
using?

Have a nice day,
