Hi Stephan >> So, how can I get the same result above without using time() ?? >>Or if it not possible, how can I extract (yes, I tried with extract() >>function too) time from a timestamp column? >> I know it's quite simple question... but I haven't find any clue! >> > > In general you could probably use CAST(materiadata as time) I'd guess. > I believe that at this point you can still use the functions, you just > need to double quote them ("time"(materiadata)) to differentiate them > from the type specifiers. > Well, it seems to work only with "timestamp without time zone" type. But worked. Thanks a lot.For me it's a new approching not using functions such as time, but "casting" it to a "time" type ( like <sql>select materiadata::time from materia;</sql>).If PostgreSQL development group change it's point of view, I suppose there's some advantage. Do you know some advantages ?? bests regards -- []'s Lucas Brasilino brasilino@recife.pe.gov.br http://www.recife.pe.gov.br Emprel - Empresa Municipal de Informatica (pt_BR) Municipal Computing Enterprise (en_US) Recife - Pernambuco - Brasil Fone: +55-81-34167078
