Oracle Database Discussions

Hi folks,

My question sounds to be something weird, but wanted to be cautious. I see a lot of users in my environment with multiple roles assigned to them. When i checked the roles of an user who has three roles assigned to him, i noticed that all the roles have some tables in common with the same grants in all the three roles, and all these three roles are assigned to the same user. Will there be any problem?

An example to explain my senerio...

User scott has three roles A,B and C assigned to him. All the three roles have execute on xy.abc procedure and select,insert,update,delete on xy.xyz table. Will there be any problem to the user who is assigned all these three roles. Will there be any confusion from oracle to chooose from which role?

Thanks
