I have an audit table that I am trying to get a count of the number of distinct entries per day by the external table key field. I can do a select count(distinct(id)) from audit where timestamp >= '01-may-2007' and get a total count. What I need is a way to group on each day and get a count per day such that the result would be something like date count 01-may-2007 107 02-may-2007 215 03-may-2007 96 04-may-2007 0 I would prefer the 0 entries be included but can live without them. Thanks. Oh, postgres 7.4 by the way. Edward W. Rouse ComSquared Systems, Inc. 770-734-5301
SELECT TIMESTAMP, COUNT(DISTINCT(ID)) FROM AUDIT GROUP BY TIMESTAMP ORDER BY TIMESTAMP ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
