Update語句根據選擇

Question

我必須聲明

update Clients 
set StatusID= 4 
from (select c.clientid 
from Clients c 
where CategCode = 'CH' and StatusID in (1,2,6) and DATEDIFF(YEAR,dob,GETDATE())>5) 

它扔我的錯誤

Msg 102, Level 15, State 1, Line 5 
Incorrect syntax near ')'. 

你看看有什麼可以導致此錯誤？

我試圖用這個聲明，但其設定狀態4對所有客戶端

update Clients 
set StatusID= 4 
WHERE EXISTS( 
select clientid,DOB,DATEDIFF(YEAR,dob,GETDATE()) 
from Clients 
where CategCode = 'CH' and StatusID in (1,2,6) and DATEDIFF(YEAR,dob,GETDATE())>5 

Answer 1

試試這個

update c 
set c.StatusID= 4 
from Clients c 
where CategCode = 'CH' and StatusID in (1,2,6) 
and DATEDIFF(YEAR,dob,GETDATE())>5 

你的第二個查詢應該是

update c 
set StatusID= 4 
from Clients c 
WHERE EXISTS( 
select 1 
from Clients x 
where CategCode = 'CH' and StatusID in (1,2,6) and x.clientid = c.clientid)
