How to use "and" and "or" in a "Where" clause

Question

I have a query that is gathering information based on a set of conditions. Basically I want to know if a location has paid out more than $50 for the day OR the comment section has the word "filter" in it...

My query is:

SELECT        Store_Id, Paid_Out_Amount, Paid_Out_Comment, Paid_Out_Datetime, Update_UserName, Till_Number
FROM            Paid_Out_Tb
WHERE        (Store_Id = 1929) AND (Paid_Out_Datetime >= DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0)) AND (Paid_Out_Datetime < DATEADD(day, DATEDIFF(day, 0, 
                         GETDATE()), 0)) AND (Paid_Out_Amount > 50) OR
                         (Paid_Out_Comment LIKE N'%' + 'Filter' + '%')

The problem is It returns 460 results and should only return 2.

Answer 1

AND takes precedence over OR. You need to group your conditions if you want to control the precedence. Try this:

SELECT        Store_Id, Paid_Out_Amount, Paid_Out_Comment, Paid_Out_Datetime, Update_UserName, Till_Number
FROM            Paid_Out_Tb
WHERE        (Store_Id = 1929) AND (Paid_Out_Datetime >= DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0)) AND (Paid_Out_Datetime < DATEADD(day, DATEDIFF(day, 0, 
                     GETDATE()), 0)) AND ( (Paid_Out_Amount > 50) OR
                     (Paid_Out_Comment LIKE N'%' + 'Filter' + '%') )

Answer 2

You need to wrap your Paid_Out_Amoutn and Paid_Out_Comment criteria in a second set of parentheses:

SELECT Store_Id, Paid_Out_Amount, Paid_Out_Comment, Paid_Out_Datetime, 
    Update_UserName, Till_Number 
FROM Paid_Out_Tb 
WHERE (Store_Id = 1929) AND (Paid_Out_Datetime >= 
    DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0)) AND 
    (Paid_Out_Datetime < DATEADD(day, DATEDIFF(day, 0, GETDATE()), 0)) AND 
    (
        (Paid_Out_Amount > 50) OR (Paid_Out_Comment LIKE N'%' + 'Filter' + '%')
    )
