Originally Said By: Eric Mittman

Unless you know that you need a specific type of join you should probably just use a JOIN by itself. I only use inner and left type of joins when I have a specific need for them.

thanks eric, so when would you for example use an inner or left join?

i looked up the article but very vague and just wondering if you could give a simple answer to when you would use one or the other?

does any of them make a difference to performance?

many thanks
