使用連接時DELETE查詢中的錯誤

Question

註釋DELETE語句並嘗試使用SELECT語句時，代碼運行正常。 請幫助

DELETE FROM 
--select * from 
Site as s 
join 
(select SiteID,Code, Name, Dense_rank() over (partition by Code order by SiteID) as Rank from Site 
) as t 
on s.SiteID = t.SiteID 
WHERE t.Rank != 1 

獲得以下錯誤消息

Msg 156, Level 15, State 1, Line 5 
Incorrect syntax near the keyword 'as'. 
Msg 156, Level 15, State 1, Line 8 
Incorrect syntax near the keyword 'as'. 

Answer 1

你不能別名delete表，但delete可以參考的別名。取而代之的是：

delete from Site as s 
... 

嘗試：

delete from s 
from Site as s 
...
