UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Support What is the "MUL" key in MySQL?

Howdy,

What does "MUL" mean in MySQL for the key?

How does it get created when the create procedure doesn't state this?

I see that it has something to do with it being "indexed", but what does it mean/do?

I'm guessing maybe "multiple" instances?

Any insight would be appreciated...

Thanks, Bill
