Extract is not the same as PostgreSQL date_trunc. Extract returns the requested value as an integer, while date_trunc returns a DATE or TIMESTAMP truncated to the requested date field, example from http://www.postgresql.org/docs/current/static/functions-datetime.html#FUNCTIONS-DATETIME-TRUNC : SELECT date_trunc('hour', TIMESTAMP '2001-02-16 20:38:40'); Result: 2001-02-16 20:00:00 SELECT date_trunc('year', TIMESTAMP '2001-02-16 20:38:40'); Result: 2001-01-01 00:00:00 > On Tuesday, February 11, 2014 4:42 PM, Maximiliano Robaina > <maxi_roba...@yahoo.com.ar> wrote: > > Hi, > > Is there an equivalent function to trunc datetime fields in firebird ? > Something like date_trunc in postgre [1]
