sql - SQL虚拟列

我收到“ SQL错误：ORA-01733：此处不允许使用虚拟列”

这是我的代码：

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

有任何想法吗？我被困在使用Oracle的过程中，因此发现无法执行Update / From语法...因此我正式圈了圈圈马车

最佳答案

尝试使用等效查询

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
    )
