Hi,

Consider the following structure :

alt text

Ignore the table user_token.

Now, imagine that you need to get all the roles related to an user, wich may be through it's related groups or directly related to him. In case the same role appears related to a group and the user directly, the role related to the user will prevail over the role given by the group.

Is there any chance this could be done in a single query?

Cheers!
