RES: How to add days to date - Mailing list pgsql-general

Michael :

I change my query to this :

SELECT CAST( '2006-08-01' AS DATE ) + FP.carencia + ( FP.prazo * (
MFP.parcela - 1 )) AS vencimento
  FROM fi_mov_formas_pagamento MFP
       LEFT OUTER JOIN fi_formas_pagamento FP ON ( MFP.idformapagamento =
FP.idformapagamento AND MFP.idempresa = FP.idempresa )
       INNER JOIN hd_cabecalho HDC ON ( MFP.idmovimento = HDC.idhelpdesk AND
MFP.idempresa = HDC.idempresa )
  WHERE MFP.idmovimento = 1
 AND MFP.idempresa = 1
 AND MFP.idtipomovimentacao = 1

And i run ok now.

Thanks for your help.

Alejandro
