Unsigned Int datatypes Does Microsoft SQL Server support unsigned integer data types?

I am trying to learn a bit more about the data type choices and helping a friend in his database project, I know that MySQL does.
No. The numeric data types are all signed.

For example an int is from approx. -2^31 to +2^31.

If you have a value just shy of 2^32 you will have to use a larger data type such as bigint. There are finer points here, but out of scope of this discussion.

Why aren&#39;t unsigned integer types available in the top database platforms?
