expr1: [colA] = [colB], and then have the criteria in the field be equal to false.

It will evaluate to NULL instead of false because Access is whacked out.

Gud, that's the answer. I dislike that it's the answer, since it means I need a more complex WHERE clause to catch nulls and normal inequality. Does "=" have three possible values in most RDBMSs?

Looks like MySQL behaves the same way, and includes a "NULL safe equal" to accomodate it.

I had no idea.

Sometimes the truth hurts.

Yeah, I don't think there's any way around a more complex where. This is cludgy, but...

SELECT TableA.colA, TableA.colB
FROM TableA
WHERE [colA]<>[colB]
OR (IsNull([colA])=True AND IsNull([colB])=False)
OR (IsNull([colB])=True AND IsNull([colA])=False);

You don't need the last bit since your dataset doesn't contain nulls in B, but you would if it might.

Barkley? Is that actually Barkley?

Drawn out of lurking by SQL?

SQL is hot. Don't let the mundanes tell you different.

Okay--flipping tech. Cell phones. I'm a Cingular customer who'd like to have an easier time texting (I have a RAZR, and the T9 is better than the Ericsson that preceded it, but still). I'd like to be able to read email on the thing, but don't care too much about sending it. Camera's good, don't need video or particularly hi-res.

I need Bluetooth, and would like it to be able to serve as a modem.

There's some education I'm missing. 3G? What transmission technologies should I be looking at?

I have an irrational dislike for Windows, so I'm looking at the Pearl.

Does anyone know the delivery dates for the iPhone or the Linux Treo?

SQL is hot. Don't let the mundanes tell you different.

I don't know how the squggles get along without it.

The iPhone is supposed to arrive towards the end part of June. They haven't announced an exact date yet. That's the one that I'm waiting for. Don't try any of the WindowsMobile devices, they really aren't good, I used an 8125 for most of last year until it died about a week ago so I'm using a RAZR V3i until the iPhone comes out and I can snag one.

BTW, cool Podcast ND.

Thanks! I'm glad you like it. We're having a blast recording it. We are watching Ice Pirates and Terror Firmer on Sunday to prep for the next episode.
