Thanks Brenden, I think I got it:
SELECT *
FROM CMS_ACL
Join CMS_ACLItem on CMS_ACL.ACLID = CMS_ACLItem.ACLID
Join CMS_role on CMS_ACLItem.RoleID = CMS_Role.RoleID
Join CMS_Tree on CMS_Tree.NodeACLID = CMS_ACL.ACLID
where ACLInheritedACLs = '' and NodeIsACLOwner = 1 and RoleDisplayName like 'Giving Editor%'
