Hil list,

I have a query but my IDE (Delphi) does not accept "to_char" capability. Is
there a way to reproduce the same query without using to_char function ?

Here is my query:
SELECT to_char(quando,'dd/MM/yyyy HH24:MI'),count(id)
FROM base.tentativa
WHERE (SESSAO_ID = 15)
GROUP BY to_char(quando,'dd/MM/yyyy HH24:MI')
order by 1

Regards ...
