Update语句根据选择

Question

我必须声明

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) 

它扔我的错误

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

你看看有什么可以导致此错误？

我试图用这个声明，但其设定状态4对所有客户端

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

试试这个

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

你的第二个查询应该是

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)
