您的代码实际上不是PL / SQL，但主要是SQL * plus脚本（特别是 VARIABLE 既不是PL / SQL也不是SQL）。

为什么不把它变成纯PL / SQL：

DECLARE
  StayWorkflow_Id_max number;

BEGIN
  SELECT max(StayWorkflow_Id)+1 into StayWorkflow_Id_max  from MVStayWorkflow;

  insert into MVStayWorkflow (StayWorkflow_Id, Stay_Id, Passage_Id,
            User_Id, RespUnit_Id, Resource_Id, WorkflowAction, CurrentState,
            PreviousState, WorkflowTime, UserStamp, TimeStamp)
        values (StayWorkflow_Id_max, 98485, 129844, 1, '', '', 11, 7, 7, to_char(sysdate, 'YYYYMMDD HH:MI:SS'), 1, to_char(sysdate, 'YYYYMMDD HH:MI:SS'));

  insert into MVStayWorkflow (StayWorkflow_Id, Stay_Id, Passage_Id,
            User_Id, RespUnit_Id, Resource_Id, WorkflowAction, CurrentState,
            PreviousState, WorkflowTime, UserStamp, TimeStamp)
        values (StayWorkflow_Id_max+1, 66311, 114593, 1, '', '', 11, 7, 7, to_char(sysdate, 'YYYYMMDD HH:MI:SS'), 1, to_char(sysdate, 'YYYYMMDD HH:MI:SS'));

  insert into MVStayWorkflow (StayWorkflow_Id, Stay_Id, Passage_Id,
            User_Id, RespUnit_Id, Resource_Id, WorkflowAction, CurrentState,
            PreviousState, WorkflowTime, UserStamp, TimeStamp)
        values (StayWorkflow_Id_max+2, 83742, 110157, 1, '', '', 11, 7, 7, to_char(sysdate, 'YYYYMMDD HH:MI:SS'), 1, to_char(sysdate, 'YYYYMMDD HH:MI:SS'));

  insert into MVStayWorkflow (StayWorkflow_Id, Stay_Id, Passage_Id,
            User_Id, RespUnit_Id, Resource_Id, WorkflowAction, CurrentState,
            PreviousState, WorkflowTime, UserStamp, TimeStamp)
        values (StayWorkflow_Id_max+3, 74421, 98685, 1, '', '', 11, 7, 7, to_char(sysdate, 'YYYYMMDD HH:MI:SS'), 1, to_char(sysdate, 'YYYYMMDD HH:MI:SS'));

  update SYSQLSequence set nextValue = StayWorkflow_Id_max+4 where name = '_MVStayWorkflow_auto_';

正如wallyk指出的那样，你生成ID的方式很可疑。通常，它是这样的：

create sequence StayWorkflow_Id nocache;  /* you only do that once */

insert into MVStayWorkflow (StayWorkflow_Id, Stay_Id, Passage_Id,
        User_Id, RespUnit_Id, Resource_Id, WorkflowAction, CurrentState,
        PreviousState, WorkflowTime, UserStamp, TimeStamp)
    values (StayWorkflow_Id.nextval, 98485, 129844, 1, '', '', 11, 7, 7,
            to_char(sysdate, 'YYYYMMDD HH:MI:SS'), 1, to_char(sysdate, 'YYYYMMDD HH:MI:SS'));


insert into MVStayWorkflow (StayWorkflow_Id, Stay_Id, Passage_Id,
        User_Id, RespUnit_Id, Resource_Id, WorkflowAction, CurrentState,
        PreviousState, WorkflowTime, UserStamp, TimeStamp)
    values (StayWorkflow_Id.nextval, 66311, 114593, 1, '', '', 11, 7, 7,
            to_char(sysdate, 'YYYYMMDD HH:MI:SS'), 1, to_char(sysdate, 'YYYYMMDD HH:MI:SS'));

只需使用StayWorkflow_Id.nextval每次都可以获得一个新的唯一ID，而不会因为没有种族条件而

我没有看到任何与错误信息有关的明显错误。

但是，如果SYSQLSequence是一个序列，那么直接更新它是不寻常的 - 至少 - 在某些Oracle版本中可能不允许。我相信你必须做这样的事情：

~~alter sequence SYSQLSequence increment by 4;~~

更新：好的，这也是有缺陷的，所以我已经把它划掉了。

这个PL / SQL脚本有什么问题？
