SQL Server中的左外连接效率

Question

我的SQL Server数据库有5个表，A, B, C, D, E

这两个左外连接之间有什么区别吗？

A 
(Left Join) B on A.id = B.id 
(Left join) c on B.id = C.id 
(Left join) D on D.id = C.id 
(Left Join) E on D.id = E.id

和

Select * from
(
   A 
   (Left Join) B 
   (Left Join) C
) x,
(
   D (Left Join) E
) y on x.<Something> = y.<something>
