Good Question.... but ,before select statement, he is dropping the table so select statement returns error but there is no option in answer list.
-
My eyes winked when I looked at this code
DROP TABLE [dbo].[IndexTable]SELECT * FROM indextable
Qotd aks about "the output of select statement", but as per the code this will give "error" 🙂
Though I understood the intention and answered accordingly. A nice question otherwise. Thanks Chirag!

Was a good question - but if I had to follow the script it would have resulted in an error as previously pointed out.
Drop was before select ...
Hope this helps...

I wonder what version of SQL this was tested against - running it against my Test box (2008 R2) all goes well until
INSERT INTO [dbo].[IndexTable]VALUES(3, 'Value3')
Then I get the error "Msg 8655, Level 16, State 1, Line 1
The query processor is unable to produce a plan because the index 'PK_IndexTable' on table or view 'IndexTable' is disabled."
Any ideas?

Since table "IndexTable" is a clustered table and before this insert statement, we have disabled the clustered index. This prohibits us to read/write rows into the table. And hence this error message.

+1. A tad misleading given that the table would be dropped before the select statement is executed! Answered correctly though when put into correct context.

Ha.
I missed the DROP TABLE due to the scrolling code window. Otherwise I would have been very confused. But I don't think this distracts from the point the QotD was making.
I had to check whether reorg would re enable the index. And it's only the REBUILD. Which does make sence.
Good question, even with the SELECT and DROP in the wrong order.

This would have been a good question if the author had checked that it produced the expect result before he submitted it, and corrected it when he discovered that instead of 3 rows the select returned an error. As it is, it's not actually as bad as yesterday's question, but it's not really very good either.

I do appreciate the volunteer nature of this...but it is getting very tedious to guess what is wrong with the question and or answers before taking a stab at it.
I suppose that this frustration is very much like my real working life 😉
