Question

我有两个存储过程，都是用SQL Server 2012编写的，都是在SQL Server Management Studio中执行的，它们将结果生成为xml。

但是，当这两个过程被导入到实体数据模型中，然后调用它们映射到的函数时，只有一个产生与从ssms执行时相同的结果。

我认为这必须与其中一个输入参数有关，但鉴于它们实际上并没有那么不同，我不知道为什么会发生这种情况。

这两个存储过程如下所示。 SPA在从两个环境执行时工作，SPB在ssms中执行时运行，参数对话框中输入的日期值如此“2015-07-05”，但在添加为日期值时失败（从日期下拉中获取）控制）产生类似这样的参数＃5/7/2015 12:00:00 AM＃。

任何人都可以在spb中看到一些明显的失礼，这会阻止它在从代码调用时执行但仍允许ssms正确执行它。

当通过模型中创建的功能从我的应用程序执行时，它会生成以下内容;

<PurchaseOrders/>

我欢迎任何建议。

        End Function

并在我的代码中调用它：

 Using ftpe = New FishTrackerProfessionalEntities
        Try
            Dim result = ftpe.CreateErsSalesAddSubmissionXmlByDateRange("uname", "pword", "B", "INSERT", String.Empty, String.Empty, ErsStartDate, ErsEndDate)
            xmlValue = String.Join(String.Empty, result.Select(Function(r) r.XMLF52E2B6118A111d1B10500805F49916B))
        Catch Ex As Exception

ErsStart和结束日期是Date绑定到日期编辑控件的类型的属性。

对于Spb，我们有：

Public Overridable Function GetLandingsToBePurchasedByDateAndPln (ByVal startDate As Global.System.Nullable(Of System.DateTime), ByVal endDate As Global.System.Nullable(Of System.DateTime), ByVal VesselPln As String) As ObjectResult(Of CreateErsSalesAddSubmissionXmlByDateRangeResult)
        Dim startDateParameter As ObjectParameter
        If (startDate.HasValue) Then
            startDateParameter = New ObjectParameter("startDate", startDate)
        Else
            startDateParameter = New ObjectParameter("startDate", GetType(Global.System.Nullable(Of System.DateTime)))
        End If
        Dim endDateParameter As ObjectParameter
        If (endDate.HasValue) Then
            endDateParameter = New ObjectParameter("endDate", endDate)
        Else
            endDateParameter = New ObjectParameter("endDate", GetType(Global.System.Nullable(Of System.DateTime)))
        End If
        Dim VesselPlnParameter As ObjectParameter
        If (Not VesselPln Is Nothing) Then
            VesselPlnParameter = New ObjectParameter("VesselPln", VesselPln)
        Else
            VesselPlnParameter = New ObjectParameter("VesselPln", GetType(String))
        End If
        Return DirectCast(Me, IObjectContextAdapter).ObjectContext.ExecuteFunction(Of CreateErsSalesAddSubmissionXmlByDateRangeResult)("FishTrackerProfessionalEntities.GetLandingsToBePurchasedByDateAndPln", startDateParameter, endDateParameter, VesselPlnParameter)
    End Function

它被称为是这样的;

 Using ftpe = New FishTrackerProfessionalEntities
        Try
            Dim result = ftpe.GetLandingsToBePurchasedByDateAndPln(StartDate, EndDate, VesselPln)
            xmlValue = String.Join(String.Empty, result.Select(Function(r) r.XMLF52E2B6118A111d1B10500805F49916B))
        Catch Ex As Exception

开头和结束日期是日期类型的属性。

Answer 1

问题很可能就是参数，根据我的经验，日期总是一团糟......

最常见的问题是月 - 日倒置，它发生在各种情况下，例如日期和日期时间之间的隐式转换。
看看这个：

declare @d1 date = '2016-02-03'
declare @d2 datetime = '2016-02-03'
select FORMAT(@d1, 'yyyy-MMMM-dd') ParDate, FORMAT(@d2, 'yyyy-MMMM-dd') ParDateTime

结果很有趣：

ParDate             ParDateTime
2016-febbraio-03    2016-marzo-02

因此，您可以尝试调试SPB，修改SPB中WHERE的{{1}}子句。
暂时撤消PATH ('Owner')和@startDate/@endDate

上的条件

@VesselPln

然后尝试从您的应用中调用它，它应该返回所有结果然后在-- AND (LandingDate1 BETWEEN @startDate AND @endDate) -- AND LandingHeaders.VesselPLN = RTRIM(@VesselPln)重新添加条件，测试它，我认为它仍会输出一些东西。

如果没有，您已经发现了问题，可能是与多字节字符串@VesselPln相关的问题，或者与ansi填充和尾随空格相关的问题。

如果是，请将nchar(10)和@startDate添加到@endDate的{{1}}部分，以查看SPB如何查看这些内容：

SELECT

这样你就应该在你的xml输出中看到问题所在。

我希望这会有所帮助。

存储过程在SSMS中执行时都会返回结果，但只有一个在从代码
