Java Oracle select*和rownum

我试图从表中选择所有值，并在按字母顺序排列后为每一行添加rownum。使用java，这就是查询

Select * FROM
  (Select *, rownum as row_id from
          (Select * FROM emp ORDER BY ename))
                Where row_id>=((?-1)*?)+1 and row_id<=(?*?);

我相信这是因为选择*，rownum作为row_id，这是选择所有字段并添加新字段的正确方法吗？

在Oracle中将*与任何其他列一起使用时，您需要对其进行限定。那么，试试这个：

Select e.*
FROM (Select e.*, rownum as row_id
      from (Select *
            FROM emp
            ORDER BY ename
           ) e
     ) e
Where row_id >= ((?-1)*?)+1 and row_id <= (?*?);

正确，*不能与其他任何东西混合。表。*可能会帮助您！请看我的答案。

Select e.*
FROM (Select e.*, rownum as row_id
      from (Select *
            FROM emp
            ORDER BY ename
           ) e
     ) e
Where row_id >= ((?-1)*?)+1 and row_id <= (?*?);
