Hi,
I need to convert a single column, result of a query yielding some rows with one column, into single row. I am using SQL 2000. Is it possible to do this with a Query? (Not by procedure)

Since we're going short on details -

are we pivoting or aggregating?

Before and after sample of what you have and what you'd like would be nifty...Thanks!

Your lack of planning does not constitute an emergency on my part...unless you're my manager...or a director and above...or a really loud-spoken end-user..All right - what was my emergency again?

G'day Mate,

I think I need to see an example to make this worth your while, but this type of work sounds like it would be covered by a cursor. Hit "Books online" and look for Cursor under "Transact SQL Reference".

It works by defining a variable data type, and using the process to "fetch" a record and when its done with that, it can "fetch" the next one.

Using a cursor in conjunction with "Cast" or "Convert" and some of the other text functions I'm guessing you'd be able to stitch something together.

I hope this might steer you in the right direction. This is where I would start! But for the life of me I can't think how you would be using data this way 🙂

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.
