Yup, it definitely goes back a couple of years. Do I see a question series coming? 😉

Does anyone have any real-world examples of using bitwise functions in SQL Server? I've never used them before, but maybe there were times I could/should have and just didn't know enough about them.

The whole table and column thing is a bit of overkill. You get the same result with:

select 250 | 255

I use bitwise operators occasionally, but moving towards using XML instead.

Still enjoy bitwise logic.

Thanks for the question.

Not a lot of call (that I've ever seen) for them in query language. They're useful for writing operating systems and compilers, and when you're in a tight space like an embedded system. They are also useful for RDD (resumé driven development).

I've seen it done to control flow through a set of rows, but that's about it. I've not had to implement it anywhere.

Nice question, but the explanation is little sloppy; as the columns are ints, their binary representations each have 32 bits, not the 16 povided i teh explnation. Of course the missing bits re all zero, but still ...

A new week-end question but as Carlo noticed it , an easy one for programmers in C# ( or more generally C ).

Thanks for it.
