Thread: INSERT Return Value?

INSERT Return Value?

From
Greg Lindstrom
Date:
Hello-

I am running Postgres 8.08 on a Linux system.  When I insert data into a
table I generate and store a value in the table via a trigger that fires
after the insert.  Is there a way to retrieve the value that I generate
with the trigger?  In this case, I am generating a broker number and
would like to get it back.  One method would be to grab the sequence
number of the record and then make another query, but I feel there is a
more elegant way to get the field.

Thanks for your help,
--greg

is this a pl/pgsql-trigger-function? You can RAISE NOTICE the generated
number to the font-end.

you can migrate to 8.2 and use the new INSERT | UPDATE | DELETE
returning feature

http://www.postgresql.org/docs/8.2/static/sql-insert.html
http://www.postgresql.org/docs/8.2/static/sql-update.html
http://www.postgresql.org/docs/8.2/static/sql-delete.html
