I gues that makes sense. I have a very small database, so I have not really ever considered overhead costs of doing things. Got any suggestions...

I figured that was the general direction you were heading in. A lot of that's improved with the newer updates to the framework. Certainly after them...

Bloody site!

Wiped out...

Funny story guys is that your UDF's don't work.

No matter how hard you try to perfect it.

They don't work by definition.

And nobody can do anything about it.

At least they don't...

Sorin,

Your query returns columns only from table "s".

That could be the answer! In the real world, these numbers are barcoded on envelopes and we send and receive a couple hundred thousand a month. ...

System functions are as bad here as UDFs.

But it does not mean you cannot use functions in WHERE clause at all.

You should not use it to modify values in table...

You can declare computed column using a function.

And function...

There is only risk of fooling yourself.
