Code:
random_string()
Generates a random string based on the type and length you specify.Could you repeat your question? It's not really understandable.

This will not give you a unique number and it's entirely possible for it to be duplicated.

Your question is entirely too vague. Unique to what? Are you talking distributed, globally unique keys? "Unique" in that no two generated are ever the same? No two consecutive? Numeric? Alphanumeric? Help us help you.

What good reason is there to force 6 characters? If you're talking about distributed keys, you need to use UUIDs, and they will be much longer than 6 characters. If you're not, save yourself the headache and use auto increment.
