 How many rows were affected?
[GENERAL] pl-pgsql question     24-Apr-2003

In pl/pgsql, you can find out how many rows were affected by a statement
by using GET DIAGNOSTICS immediately after the statement in question.

This is how the statement is used with ROW_COUNT. With ROW_COUNT, the
statement before the GET DIAGNOSTICS must be an INSERT, UPDATE or
DELETE.

    DECLARE
        rowcount    integer;
        ...
    BEGIN
        [INSERT | UPDATE | DELETE] ....
        GET DIAGNOSTICS rowcount = ROW_COUNT;

The GET DIAGNOSTICS statement can also be used with LAST_OID to fetch
the OID of the last INSERT statement, if it had an OID. If the table
did not have OIDS, it returns 0.
