    This is far from an optimal solution, but it will work as specified:

    select char(rand()*26+65)+char(rand()*26+65)+char(rand()*26+65)

    Example output:


    generate a GUID and take just the first 15 characters?

    Generate a bunch of random numbers and translate to their ASCII values?
