I was trying to make a basic for loop sample. Couldn't find what I did wrong. Can you please help:
BEGIN
FOR i_ IN 1..100 LOOP
INSERT INTO "MYSHM".aaa values (i_,i_ + 1 ,i_ + 2,i_ + 3);
END LOOP;
END
[ERROR ] 2.0-2: syntax error, unexpected character
Procedural code is only allowed inside a DO statement or a function body.
Using the default procedural language PL/pgSQL (but there are many other options):
DO
$do$
BEGIN
FOR i IN 1..100 LOOP
INSERT INTO "MYSHM".aaa -- column definition list ?!
VALUES (i, i + 1, i + 2, i + 3);
END LOOP;
END
$do$;
Or, better, recast your problem as set-based operation with generate_series():
INSERT INTO "MYSHM".aaa -- column definition list ?!
SELECT i, i + 1, i + 2, i + 3
FROM generate_series(1,100) i;
