I am using SQL Server 2005 but for this question I know that is not a big deal.

This query gets me my desired results:
SELECT DISTINCT SerialNum, CommentNum
FROM CSSComments WHERE BatchID = 'Test'

It returns four records which is correct.

I just need a count showing that I have 4 records.

I am trying this but I get a syntax error:
SELECT Count(*) as Count FROM
(SELECT DISTINCT SerialNum, CommentNum
FROM CSSComments WHERE BatchID = 'Test')

Msg 102, Level 15, State 1, Line 3
Incorrect syntax near ')'.

How do I get a return value of 4.

Thanks
