where 怎么写

where 如何写
UPDATE [SRO_VT_ACCOUNT].[dbo].[SK_Silk] 
  set silk_own= silk_own+10 
  where SELECT UserJID,silk_own FROM [SRO_VT_SHARD].[dbo].[_OnOffline] a left join [SRO_VT_SHARD].[dbo].[_User] b on a.CharID = b.CharID where CStatus='ONline'


帮忙看看那怎么写WHERE SELECT的写法错误。应该怎么写
 

[解决办法]

SQL code

UPDATE s   set s.silk_own= t.silk_own+10  --此处不确定你是要用哪一个的 silk_own，是s还是t，你自己改就好了  from [SRO_VT_ACCOUNT].[dbo].[SK_Silk] s  join (       SELECT UserJID, silk_own        FROM [SRO_VT_SHARD].[dbo].[_OnOffline] a        left join [SRO_VT_SHARD].[dbo].[_User] b        on a.CharID = b.CharID where CStatus='ONline'       ) t    on s.JID = t.UserJID
