Not so, not so!
Try the following two PL/pgSQL functions:
DECLARE
h INT;
k INT;
a_row a%ROWTYPE;
BEGIN
h := 1;
k := 3;
SELECT * FROM a INTO a_row
ORDER BY a.1
LIMIT 1 OFFSET (h + k);
END;
... blows up, but ...
DECLARE
h INT;
k INT;
a_row a%ROWTYPE;
BEGIN
h := 1;
k := (3 + h);
SELECT * FROM a INTO a_row
ORDER BY a.1
LIMIT 1 OFFSET k;
END;
... works.
As far as I can tell, PL/pgSQL is not evaluating the expression before
passing it on to the SQL parser. Or is the SQL parser supposed to
accept (1 + 3) ....
Oh, I see what you mean. Sorry! Should I bug-traq this problem?
