Question

我正在使用Tarazc4 sp来计算我的应用程序的资产负债表，但是当我的记录达到50000（超时错误）时非常耗时，请帮忙！现在已经不在我的脑海了!!!

SELECT *

FROM dbo.topics_getlevel()

SELECT *

GROUP BY Accounting.Topics.TopicID, Accounting.Topics.ParentID, Accounting.Topics.Code, Accounting.Topics.Description

ORDER BY Accounting.Topics.TopicID

并使用＆＃34; dbo.subtopics_getsum＆＃34;在Tarazc4 sp中运行以获得每个帐户的总和，请查看plz：

实际上，我的主题和文档表就像下面的图像一样，我只需要从documentdetail表中计算我的主题的资产负债表，并将其显示为我主题的层次结构（亲子）！ enter image description here

Answer 1

我在列中反复看到dbo.subtopics_getsum(Accounting.Topics.TopicID,@FromDate,@ToDate)。作为一个讨厌的解决方法，您也可以将其转储到像＃t1这样的临时表中，尽管它可能已经充分缓存了。

此外，我还没有看到TOP (100) PERCENT的需要，尽管它可能没什么区别。这是在某个阶段复制出来的吗？

您确实需要正确地重构此代码。

最后，我想出了这个代码，并且令人惊讶地提高了我的性能但是如果还有其他任何有助于提高性能的要点，请查看它吗？
