Wow that's the first time I heard the "Reply".wav after someone responded to one of my messages on UT. I think they should've used a deep masculine voice, instead. That really would've blown me away.
No triggers or rules. They are multiple replaces over 8 million records. I know how to optimize this and will when time permits. But I've got to get this and about 30 other methods :) with similar problems completed in a very short time.
And the biggest question is why is it different from machine to machine. Other than the hardware and the upgrade, everything else is identical.
