SQL虛擬列

Question

我收到“ SQL錯誤：ORA-01733：此處不允許使用虛擬列”

這是我的代碼：

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

有任何想法嗎？ 我被困在使用Oracle的過程中，因此發現無法執行Update / From語法...因此我正式圈了圈車

嘗試使用等效查詢

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
    )
