If everything seems to be going well, you have obviously overlooked something. RonPlease help us, help you -before posting a question please read Before posting a performance problem please read Henrico Bekker SSCrazy Group: General Forum Members Points: 2403 Visits: 3600 even though x=y, and y=x, your case statement catered for the following result:`'v3 = v2'` and no where specifies v2=v3."None of the Above" should be correct as well. ---------------------------------------samaritan is always watching wloong SSCommitted Group: General Forum Members Points: 1916 Visits: 162 I agreed! From the programming logic, "v2 = v3" could not be displayed! In fact, the right answer should be "None of the above". If the editor admit that it is a typo mistake, then both "v2 = v3" and "None of the above" should be correct in order to be fair. Revenant SSCertifiable Group: General Forum Members Points: 6134 Visits: 4767 TomThanks for a REALLY interesting QotD. I wish I came up with this one. Tom Brown Ten Centuries Group: General Forum Members Points: 1426 Visits: 1467 Nice question Tom. CaptainStu72 Old Hand Group: General Forum Members Points: 388 Visits: 113 Must say I agree with Henrico Bekker, the case statements at no point say v2 = v3, but rather v3 = v2. Whilst the mean the same thing, I agree that None of the Above should also be an applicable answer for those who are being pedantic. Cadavre SSCrazy Group: General Forum Members Points: 2902 Visits: 8448 Got it wrong because I believe it should say "v3 = v2" not "v2 = v3" Forever trying to learnFor better, quicker answers on T-SQL questions, click on the following...http://www.sqlservercentral.com/articles/Best+Practices/61537/For better, quicker answers on SQL Server performance related questions, click on the following...http://www.sqlservercentral.com/articles/SQLServerCentral/66909/If you litter your database queries with nolock query hints, are you aware of the side effects?Try reading a few of these links...(*) Missing rows with nolock(*) Allocation order scans with nolock(*) Consistency issues with nolock(*) Transient Corruption Errors in SQL Server error log caused by nolock(*) Dirty reads, read errors, reading rows twice and missing rows with nolockCraig Wilkinson - Software EngineerLinkedIn vinucool35 SSC-Enthusiastic Group: General Forum Members Points: 151 Visits: 18 Answer is v1 > v2 v1 > v3 v3 = v2 v4 > v1and not "v1 > v2 v1 > v3 v2 = v3 v4 > v1" rfr.ferrari Ten Centuries Group: General Forum Members Points: 1415 Visits: 13625 good question and explanation!!!!thanks Tom!!! rfr.ferrariDBA - SQL Server 2008MCITP | MCTS remember is live or suffer twice!the period you fastest growing is the most difficult period of your life!
