Hi Jeff

Thanks for the input.

The code I'm (trying to) write needs to check the sequence of the codes in post #1.

I don't think the code I posted from my WHERE clause is quite right (although I think the theory is sound).

I'd be grateful for any advice you could give.

Have you tried going for a fancier pattern? If all you want is to find the pattern, no sense in parsing the string

I kind of think this is what you want:

select code from #test where patindex('%Q2[234]%Q0[78]%',code)>0

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?

Thanks Matt

That looks to have done the trick.

I'll have to double-check but it looks good at first pass.

I'll second Matt's solution over splitting the data. Even if you use a CLR to do the split, it'll still be really expensive compared to Matt's solution.

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.
