I quetion one more time. I must have a function ? Isn't another way to
implement it without using functions ?
Not in PostgreSQL. Here's a sample of something similar to what you were doing.
CREATE LANGUAGE plpgsql;
CREATE TABLE carga (
id NUMERIC,
desc_txt TEXT,
PRIMARY KEY (id));
CREATE OR REPLACE FUNCTION for_loop_func (num_iter INTEGER)
RETURNS void AS
$$
DECLARE
iter NUMERIC;
tmp_num NUMERIC;
BEGIN
FOR iter IN 1 .. num_iter
LOOP
-- some computations
tmp_num = iter * 2;
INSERT INTO carga
(id, desc_txt)
VALUES (tmp_num, 'My Text for ' || iter || '*2 = ' || tmp_num);
END LOOP;
RETURN;
END;
$$ LANGUAGE plpgsql;
--SELECT for_loop_func(1000000);
SELECT for_loop_func(10);
