help with query

Using the included stored procedure I am getting the following result.
However I need this to return the DISTINCT forum.ID from the tables while
maintaining the correct post count, topic count and last post date.

Columns
c_ID t_ID f_ID c_Name f_Titlle TopicCount PostCount LastPostDate

I think that this is what you need:

SELECT C.ID AS c_ID, f.ID AS f_ID, C.Name AS c_Name, F.Title AS
f_Title,
COUNT(DISTINCT t.ID) as TopicCount,
COUNT(*) AS PostCount,
MAX(P.[Date Entered]) AS LastPostDate
FROM Category C
INNER JOIN Forum F ON F.cat_ID = C.ID
INNER JOIN Topic T ON T.f_ID = F.ID
INNER JOIN Post P ON P.t_ID = T.ID
GROUP BY C.ID, f.ID, C.Name, F.Title

It would have been useful if you also posted sample data (as INSERT
statements) and expected results; see: http://www.aspfaq.com/5006
