As I said, it was my understanding that the SQL optimizer did not do that for simple (non-query) expressions connected by boolean operators, that it evaluated left-to-right.

Hmm, don't see much wrong, except maybe:

WHERE ID = @liMaxMaxID + 1

You're checking for a specific ID value, not just the first value greater than the prev max. Is...

I thought SQL Server did always...

That's not practical in this type of situation.

If the log is already bloated because it previously wasn't backed...

What about an approach that used a generic stored proc to dynamically create static code for a specific table?

That is, the code could handle any table name passed to it,...

How many rows are in the temp table?

How many average duplicates are there of each ID, roughly, in each table? That is, what is the value of:

SELECT COUNT(DISTINCT ID)...

I agree. Qods have become so careless and subjective as to be worthless.

As everyone else has noted, wth does "dob" have to do with "join" date?

Because then the exact same check that works...

Wouldn't L.A. fall under CA law?

Where...

But even your own "timeanddate.com" link makes it clear that the official birthdate is Mar 1 in non-leap years:

while others celebrate their birthday on March 1 because they do...

So when someone asks you how old you are, you count days before you answer? Nonsense.

The best...

Well, I guess it's nice to see that there are still places where low standards prevail and former govt employees can find actual work.

I admit I don't care for all the "uber-geeky" solutions; it's just too hard later for s/o later to verify that the code produces a correct result.

But leap year birthdays...

That's for sure. I love "experts" who don't know how to tell what the current SQL activity on the box is.

Interesting. I guess my concern is that if a (very) large table(s) need updated, you could see a significant hit to your performance from autoupdate of stats. Also,...
