Sql 计算跑步总量的最佳方法是什么？

这是我在3月份运行的SQL查询，它运行得非常完美，但当我在4月份运行它时，它就一直在运行

然而，如果我避免运行total，它会再次运行良好

如果语法错误或设计有替代方案，请提供帮助

计算跑步总量的最佳方法是什么？如何优化上述查询？

我正在按照Tanveer Khan的建议编写游标

只需将CTE的结果插入一个临时表，即可避免计算运行总计

;WITH T AS
(
   -- Your queries 
)
SELECT * INTO #TEMP
FROM T

现在，您需要从上面的临时表中选择结果，以使用游标查找运行总数

现在，运行总数将保存在临时表的一列中，您可以使用

SELECT * FROM #TEMP

请随时询问任何疑问。

最好的祝愿。

你知道问题是什么！您的查询进入循环，请提供一些数据。当您删除SELECT并仅保留时，它如何能够完美运行？SQL Server引擎将报告语法错误。实际上，您正在计算每条记录的运行总数。对于第二条记录->第一条记录+第二条记录，对于第三条记录->第一条记录+第二条记录+第三条记录…等等，它肯定会变慢。需要注意的是，即使游标有性能问题，游标计算running total的速度也比上面提到的要快@Tanveer KhanCan您是否共享实际的查询计划？使用此链接解释运行total的最佳方式这对您有帮助吗@坦韦尔汗

SELECT * FROM #TEMP
