Hi,

I have table tblUsers with sample value

UserID Leavedate
1 01\03\2011
1 02\03\2011
1 03\03\2011
1 06\03\2011
1 10\03\2011
1 11\03\2011

I want to retrieve the result set as date range like below structure with comma separtor.If three consecutive dates comes then group it otherwise make it as single .

Excepted Result would be

userID Leavedate
1 01\03\2011 - 03\03\2011,
06\03\2011.10\03\2011 - 11\03\2011

That's actually a PITA to do. The first question is: what data type are you going to return?
You have to return a string: because you are potentially returning a range, or comma separated values.
But because you don't have a return type to indicate if the result is a single or multiple result, you have to post-process your results to work out what dates you actually have.

Mika is correct that you would have to create this as a stored procedure in order to return what you have asked for, but I would suggest that a better way might be to re-think either your database structure, or what you are doing with the data - as the returned row will need re-processing for almost any application you want to use it for.

What are you trying to achieve, that you need this?

Solution 1

Perhaps the simplest way to do this is to create a small procedure and handle the concatenation in the procedure. Then return the result set from the procedure.
