>Random and Unique are not the same as I found out a few years ago. At a conference there was to be a contest and we used Rand to generate random badge numbers. When the code was run there were repeating values generated.

I know that Random are not the same as Unique. I made a test where I ran the INT(RAND()* 99999999), 10000 times and I got 10000 different values, so that's why I said 99,99% unique.
