Thanks, but that is my problem actually !
I've got few tables that have complex primary keys. I know that this
shouldn't be, but I have to work with it (no choice, much pain !). Since
I've got to write a php program that will have to work for both type of
tables (many with simple keys, and few with complex ones), how can I
have a same querry work with both ?
