Question

由于某种原因，下面的代码返回结果，但输入顺序不正确。

任何人都有任何想法，因为我已经看了几个小时并且还没有发现问题：

    BEGIN
        SELECT @TotalPages = CEILING(COUNT(*)/@PageSize)
        FROM MemberMail

        WITH InMailsCDDESC AS

            SELECT ROW_NUMBER() OVER(ORDER BY a.CreateDate DESC) AS RowNum,
            a.MemberMailID,     -- 1

            AND a.FromDeletedFlag = 0
        )
        SELECT * FROM InMailsCDDESC
        WHERE RowNum BETWEEN (@PageNum - 1) * @PageSize + 1 AND @PageNum * @PageSize
    END

非常感谢您提供的任何帮助。非常感谢，保罗

Answer 1

如果您需要特定订单，则需要在SELECT语句中使用ORDER BY。

由于您没有在SELECT语句中指定ORDER BY，因此数据库可以按照自己喜欢的顺序自由返回行。

修改

我正在添加Lamak的评论以完成这个答案：

ORDER BY窗口定义中的row_number()仅用于计算row_number()函数的结果。它不用于对整体结果进行排序（这是窗口函数之美的一部分）

要按计算的row_number()排序，您需要在最终的SELECT语句中添加ORDER BY RowNum。

Answer 2

我相信您需要在最终的select语句中添加orderby，可能是通过rownum命令？

SQL语句输出顺序不正确，不确定原因？
