Re: in Pl/PgSQL, do commit every 5000 records

Hi Bruno,

You can't do commits inside of a function.

The example I have is:

CREATE OR REPLACE function test() returns boolean AS $$
DECLARE
... ...
  counter                INTEGER := 0;
BEGIN
... ...
  query_value := ' .....' ;
  OPEN curs1 FOR EXECUTE query_value;
  LOOP
     FETCH curs1 INTO studid;
     EXIT WHEN NOT FOUND;

     query_value := ' INSERT INTO ... ...';
EXECUTE query_value ;

     counter := counter + 1 ;
     IF counter%5000 = 0 THEN
        counter := 0;
        COMMIT;
     END IF;

  END LOOP;


CLOSE curs1; ...
END;

... ...

The above function works ok. "can't do commits inside of a function " , do you mean although the function complied ok and run successfully, but it did not really commit insertion actions at every 5000 records?

I think you are misremembering advice about not do inserts with a transaction per row which will have
a lot of overhead for all of the commits.
