Обсуждение: Timestamp, epoch and a bit confusion
Hello all. I working with postgreSQL for a couple of months, and now I trying to convert timestamp columns in epoch and epoch to timestamp columns. So far I could reach, all SQL I find by 'googling' returns an error. Where can I find some documentation with this convertions fo 8.2.x branch? I think the Manual on the main site is not very helpfull in this case!!! ;-( Thanks in advance. -- Valter Douglas Lisbôa Jr. Sócio-Diretor Trenix - IT Solutions "Nossas Idéias, suas Soluções!" www.trenix.com.br contato@trenix.com.br Tel. +55 19 3402.2957 Cel. +55 19 9183.4244

Thank you, very much. I pass through extract(epoch from x).
