Dear All,
Following is the description of the problem.
Ex: My table mtab holds the data in the following format
AccountID Account_ServiceNo Description
IND_1 1 This is Desc1
IND_1 5
IND_1 8 This is Desc3
IND_1 10 This is Desc4
Now I want output in following format
AccountID Col1 Col2 Col3 Col4
IND_1 This is Desc1 This is Desc3 This is Desc4
In my table there for a single accountid there may be max of 72 account_serviceno(ie. most of the cases have upto 6 only) and out of these cases some does not have any description. So i want to eliminate all these rows and display in the above format.
Regards

You'll find there's about a million of us that are gonna recommend that you don't do that for way too many reasons to post here. But, if you insist, you'll need to do a dynamic cross-tab. See Books Online for how to do a Cross-Tab and convert it to Dynamic SQL to achieve your goal.

If you actually want tested code that might actually work, please see the URL in my signature for how to present your table structure and some sample data.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

I already did suggest a solution... lookup Crosstab in BOL and convert it to dynamic SQL.
