C# 存储过程获取正确的行，但SqlDataAdapter不填充相同数量的行

我有一个VS2010.NET4.0Web服务，它应该返回记录的数据表。到今天为止，它似乎一直工作得很好。如果我通过SQLServerManagementStudio将5个参数（3个int和2个datetimes）传递给它，我将得到预期的所有行。但是，当我运行服务并检查ds.Fill（MyTable）行上的变量时，有些行将不显示

我刚刚注意到一些奇怪的事情，当我搜索标记号为1-270的项目时，我得到了SSMS和.Fill中的所有行。每当我尝试返回标记号介于271和300之间的项目时，所有这些行都显示在SSM中，但没有一行返回到.Fill中。我已经检查了300多个项目，这两个项目都符合预期

这是我的存储过程。我看不出有什么特别的

因此，在SSMS中，当我运行以下命令时：

FetchLicenseReceiptData 2013、270、271、“2012-01-01”、“2012-12-31”

我有两张唱片。当通过.Fill运行时，我只得到一个（270）

当我在SSMS中运行以下命令时：

FetchLicenseReceiptData 2013，271300，'2012-01-01'，'2012-12-31'

我得到全部30行。但通过.Fill，它不会返回任何值

最后，如果我运行以下命令：

FetchLicenseReceiptData 2013、301、310、“2012-01-01”、“2012-12-31”

我在SSM和.Fill中都得到了10分

作为返回数据的示例，这里是在SSMS中返回的270和271数据。我用波浪号（~）字符替换了选项卡

这个很奇怪。希望你们中的一位大师能帮助我

解决方案： 感谢@EJBrennan对SQL分析器的建议。我以前从未使用过它，但它为我指明了正确的方向。以下是实际发送到SQL的数据：

exec FetchLicenseReceiptData@ForYear=2013、@StartNumber=270、@EndNumber=271、@StartDate='2012-01-01 00:00:00'、@EndDate='2012-12-13 00:00:00'

当我跑的时候，它给了我1排而不是2排。基本上，除了时间的00:00:00之外，这些值是相同的。最后，我将以下内容添加到存储过程的顶部，以强制执行正确的操作：

SET @StartDate = DATEADD(DAY, DATEDIFF(DAY, 0, @StartDate), 0) -- Beginning of given Date
SET @EndDate   = DATEADD(DAY, DATEDIFF(DAY, 0, @EndDate),   1) -- End of given Date

这将获取传入的@StartDate并将其强制为当天的0:0:0。然后将@EndDate设置为第二天，并将时间设置为0:0:0

同样在WHERE子句中SP的底部，我更改了“您应该使用SQL事件探查器跟踪和复制/粘贴从应用程序发送到SQL server的SQL”。捕获后，将其粘贴到SSMS中，查看结果是否与手动键入SSMS的结果相同或不同-您需要排除“用户”错误。您还需要确保应用程序运行的数据库和服务器与SSMS运行的数据库和服务器相同，而不是数据库的测试或开发版本。例如，请尝试填充数据集而不是数据表，然后查看数据集中的内容。特别是，检查数据集以查看是否创建了多个表。

SET @StartDate = DATEADD(DAY, DATEDIFF(DAY, 0, @StartDate), 0) -- Beginning of given Date
SET @EndDate   = DATEADD(DAY, DATEDIFF(DAY, 0, @EndDate),   1) -- End of given Date
