Re: Need help with query William,
If I understand your results correctly what you want to do is something
like this:
SELECT
DATEADD( dd, -1 * DATEPART( dw, Date ), Date ),
Explanation,
SUM( TotalCount )
FROM
DSL_History
WHERE
Date BETWEEN '3/1/03' AND '6/6/03'
GROUP BY
DATEADD( dd, -1 * DATEPART( dw, Date ), Date ),
Explanation,
Regards,
