challenge

Hey folks,

i have a large user Database (13k+), and for some reason i need to create random names. The users table has "first_name" and "last_name". Now i want to have 10 concats of full_name and last_name of two completely random rows. Is that even possible with SQL?

My other idea was just to create a full_names and last_names table … but that would'nt be as much challenging.

Oh, and it should not take up too much performance :) (so order by rand() is not an option ;))
