MrciYou are quite right in my Answer
But I have a view and send it to the different conditions By Collection (Asp.net)
I added the condition to Having, but will not display anything.
SELECT FirstName, LastName, CompanyID, NCode, FatherName, nPercent, NationalCode
FROM View_Report_Payesh_Tools
WHERE (Tools = N'Walker') OR
(Tools = N'Cane')
GROUP BY FirstName, LastName, CompanyID, NCode, FatherName, nPercent, NationalCode
HAVING (COUNT(Tools) = 2)
What you posted above has additional columns. I would start by looking at your data. Any differences in the data you are grouping on could be part of the problem.
