One more problem :)
I wrote my tables and variables and it looks like that:
SELECT CASE WHEN cena=0 AND cenaeur<>0 THEN cena=cenaeur
*(SELECT eur FROM devizni ORDER BY eur OFFSET 20 LIMIT 1)
ELSE cena END AS cena, CASE WHEN cenaeur=0 AND cena<>0
THEN cenaeur=cena/(SELECT eur FROM devizni ORDER BY eur
OFFSET 20 LIMIT 1) ELSE cenaeur END AS cena_eur from oglasi
ORDER BY posr, id_regije;
cena, cenaeur and eur are all double precision.
When I try to execute it, I get following error:
ERROR: CASE types "float8" and "bool" not matched
I have no boolean in neither table... ok, comparision is binary,
but why do I get that error?
What can I do to make it work? :/
Tnx,
May
