这些视图已经更改了名称,但以下内容应该对sql Azure起作用
select m.name as Member,r.name as Role from sys.database_role_members inner join sys.database_principals m on sys.database_role_members.member_principal_id = m.principal_id inner join sys.database_principals r on sys.database_role_members.role_principal_id = r.principal_id
