Re: Conditional commit inside functions

Hello!

I tried the following, but still one transaction:

SELECT insert_1Mio();

(parallel select count(id) from employee; is done)

CREATE OR REPLACE FUNCTION insert_some(start_i INTEGER, end_i INTEGER)
RETURNS void
AS $func$
DECLARE
BEGIN
FOR i IN start_i..end_i LOOP
INSERT INTO employee (id, department, firstname, lastname) VALUES (i, i, 'John' || i, 'Smith' || i);
END LOOP;
END;
$func$ LANGUAGE plpgsql;

CREATE OR REPLACE FUNCTION insert_1Mio() RETURNS void
AS $func$
DECLARE
maxcommit INTEGER;
start_i INTEGER;
end_i INTEGER;
now_i INTEGER;
BEGIN
maxcommit := 10000;
start_i :=1;
end_i := 1000000;

now_i := start_i;

FOR i IN start_i..end_i LOOP
IF MOD(i, maxcommit) = 0 THEN
PERFORM insert_some(now_i, i);
now_i := i + 1;
END IF;
END LOOP;
PERFORM insert_some(now_i, end_i);
END;
$func$ LANGUAGE plpgsql;

Any ideas?

Ciao,
Gerhard
