Sql server 行号中的SQL ORDER BY子句错误

我想使用ROW_NUMBER（）函数并获取第一个和最新的值。 我写下面的问题。但我犯了个错误

ORDER BY子句在视图、内联函数、派生表、子查询和公共表表达式中无效，除非还指定了TOP、OFFSET或FOR XML

帮我解决这个问题。下面是sql查询

SELECT *
FROM(
    SELECT OPP_ID,PRJ_ID,
        ROW_NUMBER() OVER (PARTITION BY OPP_ID ORDER BY MAX(CREATION_DATE) DESC) AS RN
    FROM OPPOR
    GROUP BY OPP_ID,PRJ_ID
    ORDER BY MAX(CREATION_DATE) DESC) OP
WHERE OP.RN = 1

row\u number

函数可以自己进行聚合和排序，因此无需在子查询中使用

groupby

或

order by

（

order by

在子查询中不起作用）。不过，有点不清楚您是想通过opp\u id还是opp\u id和prj\u id进行分区。但这应该是你想要的：

SELECT *
FROM(
    SELECT OPP_ID,PRJ_ID,
        ROW_NUMBER() OVER (PARTITION BY OPP_ID ORDER BY CREATION_DATE DESC) AS RN
    FROM OPPOR
    ) OP
WHERE OP.RN = 1

不能在子查询中使用ORDER BY
