Hi all,  
I have an issue that i can not resolved by myself. I have a parent (called "user") and children (called visit\_competitor and visit\_direct). Each user have an id and can have lot of visits (competitor and direct). I need to dissociate user who have only visit\_direct, or only visit\_competitor, or both. How can I do this?

Thank you!
