Question

我正在更新两张桌子（卡片）和（accountcomment）。

首先查询：

     update card set cardstatusid = 3 where cardstatusid = 1 and card num in ('123', '456', '789');'

第二次查询：

           Update accountcomment set text = 'CARDS EXPIRED' WHERE commentcategory = 10 and accountid in ('aaa', 'bbb', 'ccc');'

由于存在大量的卡片和帐号，我需要声明一个游标并使用PL / SQL语句。

所以我写了以下内容：

    declare
    cursor c1 is select personid from card where cardstatusid = 1 and card 
    num in ('123', '456', '789');

     cursor c2 is select accountid from personaccount where personid in 
     (select personid from card where cardstatusid = 1 and card num in 
     ('123', '456', '789'));

      begin

      for r1 in c1
      loop
      update card set cardstatusid = 3
      where personid = r1.personid;
      end loop;

      for r2 in c2
      insert into accountcomment 
      values ('CARDS EXPIRED', r2.accountid, 10);
      end loop;

      end;

它给了我一个错误.....我不确定我是否使用游标错误或某些声明......我不能在accountcomment中使用更新声明，因为commentcategory 10还没有退出那张桌子。

如果我可以使用一个很棒的光标。否则在修复当前的pl / sql时会有所帮助。

谢谢！

card num不是有效的column_name（空格）。你也错过了一个＆＃34;循环＆＃34;。

这样的东西？

declare
   cursor c1 is
      select personid
        from card
       where cardstatusid = 1 and **cardnum** in ('123', '456', '789');

   cursor c2 is
      select accountid
        from personaccount
       where personid in (select personid
                            from card
                           where cardstatusid = 1 and **cardnum** in ('123', '456', '789'));
begin
   for r1 in c1 loop
      update card
         set cardstatusid = 3
       where personid = r1.personid;
   end loop;

   for r2 in c2 **loop**
      insert into accountcomment
           values ('CARDS EXPIRED', r2.accountid, 10);
   end loop;
end;

PL / SQL语句中的错误.....不给我输出
