这是一个无所不包的查询，有很多关于它的文章，盖尔·肖（Gail Shaw）像她的文章How to Confuse the SQL Server Query Optimizer一样写了好几次。没有简单的方法可以优化此查询。我的建议是使用动态SQL简化条件。您似乎也只共享了整个过程的一部分。之所以认为动态SQL是一种解决方法，而并非每次都重新编译，是因为查询非常复杂，并且可能在完全优化之前超时。 您的某些列检查是通过以下方式编写的：
AND (
-------------For BatchNo Check
------- For BatchNo Check Is Not Null
(
(a.var64_60 = @BatchNo)
AND (@BatchNo IS NOT NULL)
)
OR
----For BatchNo Check Is Null
(
(@BatchNo IS NULL)
AND (1 = 1)
)
)
可以简化为以下形式：
AND (a.var64_60 = @BatchNo OR @BatchNo IS NULL)
这类似于与表值参数中的多个值进行比较。
AND (j.ProductCode IN ( SELECT * FROM @ProductCodes) OR @ProductCodesCount = 0)
使用动态代码还将简化引擎的@ReportTypeVar条件。
请注意，即使使用动态SQL，您也需要能够对查询进行参数设置，以防止进行任何形式的SQL注入。
