It would be easier if your table was like this:userName answerNo answertest 1 righttest 2 wrongtest 3 rightThen you could use select count(*) where answer = 'right' or select sum(case when answer = 'right' then 1 else 0 end)As it stands you have to check each column separately with case statements, and sum the results.select userName, case when answer1 = 'right' then 1 else 0 end + case when answer2 = 'right' then 1 else 0 end + case when answer3 = 'right' then 1 else 0 end + etc etcWed, 08 Oct 2008 09:17:39 GMTThe Dixie Flatlinehttp://www.sqlservercentral.com/Forums/Topic582379-1291-1.aspxfirst thing that comes to mind is to unpivot to turn the columns into rows then group and count. I've already had issues with getting pivot/unpivot syntax correct, so I won't post any code.the issue here is the DB design, there shouldn't be a column for each answer, they should be on different rows. what if you had 20,30,100,1000,10000000 answers? that'd be a lot of columns.this post should altleast get someone else out there thinking of a full answer.Wed, 08 Oct 2008 09:15:00 GMTbcroncehttp://www.sqlservercentral.com/Forums/Topic582379-1291-1.aspxHello I am inserting into my table into the Columns answer1 to answer10 the string "right" or "wrong". This works fine. for example with a username username answer1 answer2 answer3 answer4 .........Test right wrong right right Is there a possibility with select count to get the rate of right answers for the total : for example 5 of 10 answers right ?
