SQL虛擬列

Question

我得到了 'SQL錯誤：ORA-01733：虛擬列這裏不允許使用'

這裏是我的代碼：

update (
    Select g.FIRST300BB from ( 
     select FIRST300BB, row_number() over (order by pitchandeventid) r 
     from gamedata_me 
     where hitterid = 5000 
     and (eventcode = 'BB') 
    ) g 
    where r between 0 and 300 
) t 
set t.FIRST300BB =1 

什麼想法？我堅持使用Oracle所以我發現我不能做更新/從語法......所以我正式盤旋貨車

Answer 1

嘗試例如

update gamedata_me 
    set first300BB=1 
where rowid in(
      Select g.rid from ( 
       select rowid rid, row_number() over (order by pitchandeventid) r 
        from gamedata_me 
       where hitterid = 5000 
       and (eventcode = 'BB') 
       ) g 
    where r between 0 and 300 
    )
