Hi Evans,
thanks for the idea. This brings up a couple more questions:
What if the value has to be a string of numeric characters? Is there a way to generate sequential numbers and convert them to characters?
How can I just return say 10 characters from the newid() function? Or would that then mean the values won't be unique?
