Re: For loop

I rewritte the Jonah's function to:

FOR iter IN 1 .. num_iter
LOOP
-- some computations
INSERT INTO carga (descricao) VALUES ('CardPass');
END LOOP;

My ID is now() by default

And it was in 23sec

After I changed the insert to:
INSERT INTO carga (id,descricao) VALUES ('2007-03-13
10:20:20','CardPass');

And it was in:
19485ms

Great don't you ?
