Dynamics CRM查询实体共享给哪些人

在mscrm中，如果想查询一条记录共享给了哪些人，需要用到PrincipalObjectAccess 表，sql如下：

 select u.FullName,a.RC_name,sup.SystemUserId,POA.ObjectId from PrincipalObjectAccess POA inner
 join SystemUserPrincipals sup on POA.PrincipalId = sup.PrincipalId
 inner join SystemUserBase u
 on sup.SystemUserId=u.SystemUserId
 inner join Rc_importList a
 on a.Rc_importListId=POA.ObjectId
 where POA.objecttypecode=10004
 AND ((POA.AccessRightsMask | POA.InheritedAccessRightsMask) & 1)=1
 and POA.ObjectId='790C63D9-56A0-E311-8A54-00188B421B2B'
