Question

I have 2 tables:
First (Cases)
Second (Comments)

in one to many relation ; I’m storing the comments of each case in Comments table.

I need to select case information from Cases table which are presented in Comments table, but I want each case to be displayed ONCE ordered by comments added date (cDate)

I tried:

SELECT TOP 10  
     Cases.*,  
     comments.cDate  
FROM  
     Cases 
INNER JOIN comments 
     ON Cases.Case_ID = comments.Case_ID 
WHERE comments.Case_ID IN 
        (
           SELECT DISTINCT 
              Case_ID 
           FROM 
             comments
         ) 
 ORDER BY cDate DESC

but its retrieving the case multiple times if it has many comments. I need it to appear one time only

Thank you all, you helped alot ,,
I just added

Cases.Case_ID IN (SELECT Case_ID FROM comments) 

and it worked perfectly.

Select statement is like this now:

SELECT top 10 Cases.*,
(SELECT MAX(comments.cDate) 
       FROM comments 
       WHERE Cases.Case_ID = comments.Case_ID  ) AS cDate 
FROM Cases
WHERE Cases.Case_ID 
                 IN (SELECT Case_ID FROM comments) 
ORDER BY cDate DESC 

Thanks once again 🙂
