Don't divide by zero. <img src='images/emotions/smile.gif' height='20' width='20' border='0' title='Smile' align='absmiddle'> You need to figure out where you are doing this and fix it.

BWAAA-HAAA!!!! Even if this thread is more than a decade old, I saw the title of this thread and I knew what my answer would be. You beat me too it and I had a great laugh after a tough day. 🙂

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.

Guys you're posting answers to a question asked in 2004. I hope they've fixed the problem by now. :w00t:

It's now more than a decade and if they're anything like the people I've been interviewing lately, the I'd have to say "probably not". 😛

select COALESCE(MIN(Act) / NULLIF(MAX(Act),0), 0) as minvsmaxAct from table_name
This is what I usually do, except that I don't reply to 5 year old threads. :w00t:

I usually don't care when a thread started... especially if someone has a better idea.
