I'm creating a users table in my app and don't want the PK of the user to be predictable.  I was thinking along the lines of the SID behind an NT user account.

This seems like a standard type of issue.  Is there a standard approach?  Anyone have an sp_getNextUserSID() proc in their library?



RE: unique random key

Which version of SQL are you using?

If you are using 7.0, try using a GUID datatype with a NEWID() default.

I ran across that over the weekend.  I feel kinda silly that it was right there staring me in face :-o

RE: unique random key

You can use the scalar function Random. Use it to generate a PK. While inserting , it the statement fails, then it means the PK is already there. Make a loop unless the insert statement is successful.

Does it answer your question?
