Hi,
I want to create random customer ids. I have an auto incremented coulumn but
I would rather have a 6-8 digit/letter id randomly generated that can be
used as a unique identifier across 3 tables. Does anyone have a algorithm to
generate such a string and can you give the odds against 2 duplicate stings
being generated?
I know this is a strange ask.
R.
What about this:

And if you're really concerned about duplication, then check the dB
each time to see if it's already there -- that's what I do.
Cheers,
