Hi,
I frequently have a need to insert new rows into a table that are
based on existing rows but with small changes.
This is easy using something like
insert into foo (a,b,foo_date)
select a,b,now() from foo old where ....
returning oid
However in the application layer, I need to know which new record
corresponds with which original record
So ideally, I'd like to be able to do
insert into foo (a,b,foo_date)
select a,b,now() from foo old where ....
returning oid, old.oid
...but this doesn't work. It seems you only have access to the table
being modified in a returning clause. Is there a way I can return a
simple mapping between old oids and new oids as part of the statement
that inserts the new ones?
Cheers,
Andy
