    In SQL Server 2005 :

    you can have

    1 Clustered Index on a table and

    249 Non Clustered Indexes.

    = 250 Index

    In SQL Server 2008:

    you can have

    1 Clustered Index on a table and

    999 Nonclustered Indexes

    = 1000 Index

    Please Modify the Question Or Answers....!

    I think Raj gave right solution ...!

    I chose an incorrect answer so I could get the llink to this discussion. And then, I was even rewarded with a point.

    To add to the others, the correct answer for SQL Server 2005 (which is mentioned explicitly in the question) is not included. And to correct them, the correct answer for SQL Server 2008 is not listed either.

    For SQL Server 2005:

    Up to 1 clustered index, up to 249 nonclustered indexes, and up to 249 XML indexes (http://msdn.microsoft.com/en-us/library/ms143432%28SQL.90%29.aspx), plus a number of full-text indexes for which I was unable to find a maximum

    For SQL Server 2008:

    Up to 1 clustered index, up to 999 nonclustered indexes, and up to 249 XML indexes (http://msdn.microsoft.com/en-us/library/ms143432.aspx), plus a number of full-text indexes and a number of spatial indexes for which I was unable to find the maximums.

    That makes the correct answers: 499 + max FT indexes for SQL Server 2005, and 1249 + max FT indexes + max spatial indexes for SQL Server 2008.

    (edit - corrected a silly mistake, as pointed out by vk-kirov)

    249 XML indexes, actually.

    The maximum number of spatial indexes can be found here: http://msdn.microsoft.com/en-us/library/ms190197.aspx, and it's 249.

    So the correct answer for SQL Server 2008 is "1 clustered + 999 nonclustered + 249 XML + 249 spatial + some full-text", which is "1498 + some full-text".

    OOPS. That was a very silly mistake I made there. Thanks for correcting me; I edited my original post to reduce the chance of confusion when others read it.

    So far I never asked for a review of the QotD before it is going to be published, as this would mean a big effort for Steve or some other top experts. But today I am joining the Choir of the Dissatisfied.

    http://msdn.microsoft.com/en-us/library/ms143432(SQL.90).aspx shows it clearly: there is a maximum of 250 indices per table, one of them clustered.

    Best regards,

    I got the correct answer of 1000 but only because 250 wasnt there which was the correct answer for SQL SERVER 2005. 1000 is correct for SQL SERVER 2008. Hope this will be the last time there is an incorrect question / answer on the site as I always trust it!

    I got right anwser but it's true for the SQL Server 2008 not for SQL Server 2005.

    Please Change the question or add one more option with 250.

    I've just assumed there was typo and went with the 2008 answer.

    Any of the given options are not correct for SQL Server 2005. it is only suitable for SQL server 2008
