Personally, I'd do it with a Package. jmodic, chrisrlong or others may have some fancy decode/union/case statement...

Yeah, we play around with DECODE, CASE, etc. to do bounded pivot queries. That is, we can very efficiently pivot the results from many rows into a single row assuming that we know the maximum number of rows to be pivoted. If there is no known bound, then the best solution that I've seen is to use a procedure like Jeff suggested.

Some threads discussing bounded pivot solutions:

    Using CASE. (It's not the main post of the post, but it's in there.)

    Using math tricks.

    Using DECODE. (I can't find one right now, but you should be able to figure it out based upon the others).

Also, the discussion between Jurij and Chris in this thread about DECODE vs. CASE is quite educational.

And here is a thread where Jeff provided a procedure to do this.


HTH,

When these two get into it, watch out. It's a regular battle of the minds...
