Sql server SQL Server分页复杂查询

我想给他的核心表格编页码。我有两张桌子：

gs\U分数表

id (auto increment int)
project_id (int)
game_id (int)
user_id (int)
entry_date (datetime)
score (int)

用户

id (auto increment int)
user_name (varchar)

我想要的是通过

scores DESC

获得他的核心列表和订单列表，但我总是在第5行中得到错误（这是：

ROW\u NUMBER（）（order by total\u scores DESC）作为RowNumber

），说：

列名称“total_score”无效

谁能帮忙吗

SELECT TOP 50
    *
FROM
    (SELECT
        ROW_NUMBER() OVER (ORDER BY total_score DESC) AS RowNumber,
        gs.user_id,
        users.user_name,
        SUM(gs.score) AS total_score, 
        (SELECT COUNT(gs2.id) FROM gs_score_table AS gs2 WHERE gs2.user_id = gs.user_id AND gs2.game_id = 1) AS games_played,
        TotalRows=Count(*) OVER()
    FROM
        gs_score_table AS gs
    INNER JOIN
        users ON users.id = gs.user_id
    WHERE
        gs.project_id = 2
        AND gs.game_id = 1
        AND CAST(gs.entry_date AS date) BETWEEN '2012-04-23' AND '2012-04-23'
    GROUP BY
        gs.user_id, users.user_name) _tmpInlineView WHERE RowNumber >= 1

您不能在ROW\ U NUMBER ORDER BY子句中使用别名“total\ U score”。相反，您需要：

ROW_NUMBER() OVER (ORDER BY SUM(gs.score) DESC) AS RowNumber

非常感谢你。就这样。
