我正在开发一个ASPX文件，它将SQL存储过程的结果返回到数据适配器，然后在GridView中显示。但问题是SQL存储过程和Gridview之间的数字不匹配。它们很接近，但仅稍微偏离：千分之三。所以SQL Stored proc给了我0.199，但在Gridview中这个值= .203。而且它似乎也不是一个四舍五入的问题。此外，我查看了Gridview属性，但我没有看到任何导致此问题的内容。这一列的所有值都以相同的余量关闭。
您可以推荐哪些问题排查步骤？我在VS 2008 Shell中使用VB for SSRS，SSIS。这是我在ASPX主文件中的代码：

答案 0 :(得分：1)
您将不得不对此进行调试，以查找有问题的值在哪些步骤。
如果在调试页面时直接查看GlobalFunctions.GlobalF.GetComplaintTrendingList6(FirstMonthDate, LastMonthDate, TheLevel)的结果，有问题的数值是什么样的？
如果你进入该功能并在填充后查看DSPageData的内容，那么数值是什么样的？
如果从cmd获取具有给定参数的命令并直接在数据库上执行，那么数值是什么样的？
如果在数据库上运行跟踪并捕获为存储过程发送的实际执行命令，它是否与您认为应匹配的匹配？完全按照发送到服务器的方式手动运行，看看结果如何。
