SQL Guide : Using SQL for database administration : Managing user privileges and roles : User roles
  
User roles
Privileges can also be granted to an entity called a role.
A role is a group of privileges that can be granted to users as one unit. You can create roles and assign users to certain roles. A single user may have more than one role assigned, and a single role may have more than one user assigned.
Note  
▪The same string cannot be used both as a user name and a role name.
▪Once a user role is granted, it takes effect when the user who is granted the role logs on to the database. If the user is already logged on to the database when the role is granted, the role takes effect when the user disconnects and then reconnects to the database.
