If everything seems to be going well, you have obviously overlooked something.

Thanks for the question. It seems that the catch block is just for confusing 🙂 coz. the select query in the catch block doesn't execute

yes, nice question; try and catch doesn't hold anything.. even if you put the above code in a transaction it would still give 11.

well, instead of 10/0.00001 try using 10/0 , guess what the answer could be 😀

Thanks.

well, instead of 10/0.00001 try using 10/0 , guess what the answer could be 😀

Initially I thought this division is the key to answer this question; as "0.00001" is nearly equal to zero, the statement 10/0.00001 will introduce "divide by zero" error and hence catch block will come into picture :hehe:

All these wacky thoughts went away and I marked the correct answer. Thanks to the "Espresso Coffee" which did the magic 😀

well yes, catch block would come into the picture ; and the answer would be 4 ; the loop continues till codition breaks that.

Declare @ctr int

select @ctr = 1

while @ctr <= 10

begin

select '1'

if @ctr = 4

select 10/0

select @ctr = @ctr+1

end

end try

begin catch

select @ctr

end catch

select @ctr 'Counter'

Decent question with lots of red herrings, many thanks 🙂

Note to developers:
CAST(SUBSTRING(CAST(FLOOR(NULLIF(ISNULL(COALESCE(1,NULL),NULL),NULL)) AS CHAR(1)),1,1) AS INT) == 1
So why complicate your code AND MAKE MY JOB HARDER??!:crazy:

Please illustrate diffrent between "Begin Catch" And "Try Except"

You can read about TRY ... CATCH here: http://msdn.microsoft.com/en-us/library/ms175976.aspx

In T-SQL, "Try Except" is invalid syntax. I have no idea what language this comes from and what it does, but it sounds as just a slightly different way to solve the same problem (error handling).

Thank you for the question.

I was almost choosing the error answer because of the 10/0.00001 but then I drank some coffee and thought about it for one more second. 😀
