Perhaps we should also put in hints like.... "This is not the right answer" "Don't click this for points" "j/k" "Check this answer to win!"I saw nothing wrong with your question and understand a math joke when I read one. I liked your question, please do not change it at all.It tested much more than peoples knowledge of SQL and questions that can do that are priceless.Tue, 01 Mar 2011 14:30:05 GMTSanDroidRE: The Percent Sign in T-SQLhttp://www.sqlservercentral.com/Forums/Topic1070114-2736-1.aspxOK, the next time I submit a question, I'll be sure that the fluke answer, if there is one included, can in no way be misconstrued as a possible right answer.I think some of you are used to trick questions, so you're looking for a sneaky answer.Tue, 01 Mar 2011 14:24:43 GMTmtillman-921105RE: The Percent Sign in T-SQLhttp://www.sqlservercentral.com/Forums/Topic1070114-2736-1.aspxAmbiguity in the question..!Answer should be both..(1) divide by zero/ (2) remainder.Tue, 01 Mar 2011 14:17:51 GMTSQL-DBA-01RE: The Percent Sign in T-SQLhttp://www.sqlservercentral.com/Forums/Topic1070114-2736-1.aspx[quote][b]SanDroid (2/28/2011)[/b][hr]So happy that over 80 percent of us know math.Can you imagine how hard it would be a SQL developer or DBA if you didn't learn higher level math?[/quote]What's maths got to do with it? The use of % for modulo is a computing term. The mathemetical equivalent would be 'mod', though it's meaning is similar rather than identical.eg 8 % 6 = 2means roughly the same as 8 = 2 (mod 6)or more accurately8 ≡ 2 (mod 6)(note it's 25 years since I graduated so I'm probably about to be humilated when someone points out that I'm talking nonsense :-))Tue, 01 Mar 2011 02:25:55 GMTToreadorRE: The Percent Sign in T-SQLhttp://www.sqlservercentral.com/Forums/Topic1070114-2736-1.aspxThanks for the nice easy start to the week!Mon, 28 Feb 2011 13:15:08 GMTUMG DeveloperRE: The Percent Sign in T-SQLhttp://www.sqlservercentral.com/Forums/Topic1070114-2736-1.aspxthanks for the question - straight forward.Mon, 28 Feb 2011 12:52:37 GMTSQLRNNRRE: The Percent Sign in T-SQLhttp://www.sqlservercentral.com/Forums/Topic1070114-2736-1.aspx[quote][b]mtassin (2/28/2011)[/b][hr][quote]But somebody else could have said "Hey if I modulus 0 by 0 I get a divide by zero error!" and selected the last option, not realizing you were referring to what the % sign looks like.[/quote]Which would mean nothing unless they could find documentation supporting the obvious wrong answer. It was a multiple choice question with one right answer. Test taking 101 tells us to select the answer that is MOST correct.That was answer 3.I like it when there are joke answers that are funny IF you understand the questions, or what you are reading. It has been proven that these questions improve learning.Mon, 28 Feb 2011 09:59:53 GMTSanDroidRE: The Percent Sign in T-SQLhttp://www.sqlservercentral.com/Forums/Topic1070114-2736-1.aspx[quote][b]mtillman-921105 (2/28/2011)[/b]Yeah, I just included the "To divide by zero and get an error" as a joke. If you look at the symbol and take it at face value, that's what the symbol looks like.p.s. To be more clear, it looks like a small zero divided by zero: 0/0.[/quote]Gotta be careful with jokes... as I said, I got this one right.But somebody else could have said "Hey if I modulus 0 by 0 I get a divide by zero error!" and selected the last option, not realizing you were referring to what the % sign looks like. :)Mon, 28 Feb 2011 09:54:23 GMTmtassinRE: The Percent Sign in T-SQLhttp://www.sqlservercentral.com/Forums/Topic1070114-2736-1.aspxI feel so silly for selecting the wrong answer - which was so obviously wrong..I am humbled.
