Re: MySQL can't find index = really slow query...

What do you mean when you say "MySQL can use only one index"..?

You mean that MySQL try to understand wich index is better between the ones chosen for each table?

And there's a bad news: I can't use .fine as a primary key because it can be NULL (and this is an unchangeable condition...)

any ideas?
