hasRole([roleType,] roleName)Security Functions
Security functions provide the ability to interact with the security system.
HASROLE
Whether the current caller has the Teiid data role roleName.
roleName must be a string, the return type is boolean.
The two argument form is provided for backwards compatibility. roleType is a string and must be `data'.
Role names are case-sensitive and only match Teiid Data Roles. JAAS roles/groups names are not valid for this function - unless there is corresponding data role with the same name.
