- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我有两个存储过程,都是用 SQL Server 2012 编写的,都在 SQL Server Management Studio 中执行,并以 xml 形式生成结果。
但是,当这两个过程导入到实体数据模型中,然后调用它们映射到的函数时,只有一个过程会产生与从 ssms 执行时相同的结果。
我认为这一定与其中一个输入参数有关,但考虑到它们并没有那么不同,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都有效,SPB 在 ssms 中执行时运行,并在参数对话框中输入日期值,如“2015-07-05”,但在添加为日期值(从日期下拉列表中派生)时失败控制),产生像这样的参数 #5/7/2015 12:00:00 AM#。
任何人都可以在 spb 中发现我的一些明显的错误,这些错误会阻止它在从代码调用时执行,但仍然允许 ssms 正确执行它。

这是由 Devart 的 SPA 实体开发人员创建的代码
Public Overridable Function CreateErsSalesAddSubmissionXmlByDateRange (ByVal uname As String, ByVal pword As String, ByVal sntype As String, ByVal action As String, ByVal salesContractRef As String, ByVal auctionId As String, ByVal startDate As Global.System.Nullable(Of System.DateTime), ByVal endDate As Global.System.Nullable(Of System.DateTime)) As ObjectResult(Of CreateErsSalesAddSubmissionXmlByDateRangeResult)

End Function
它在我的代码中被这样调用:
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 end 日期是绑定(bind)到日期编辑控件的 Date 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
它的名字是这样的;
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
开始日期和结束日期是日期类型的属性。
最佳答案
问题很可能是参数,根据我的经验,日期总是一团糟。
最常见的问题是月日反转,它发生在各种场景中,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
所以你可以尝试调试你的SPB,修改SPB中PATH ('Owner')
的WHERE
子句。
暂时重置 @startDate/@endDate
和 @VesselPln
-- AND (LandingDate1 BETWEEN @startDate AND @endDate)
-- AND LandingHeaders.VesselPLN = RTRIM(@VesselPln)
然后尝试从您的应用程序调用它,它应该返回所有结果。
然后在@VesselPln
上重新添加条件,测试一下,我想它仍然会输出一些东西。
如果没有,您已经找到了问题,可能与多字节字符串 nchar(10)
相关,或者不太可能与 ansi 填充和尾随空格相关。
如果是,请将 @startDate
和 @endDate
添加到 PATH ('Owner')
的 SELECT
部分查看 SPB 如何看待它们:
FORMAT(@startDate, 'yyyy-MMMM-dd') as '@StartDate',
FORMAT(@endDate, 'yyyy-MMMM-dd') as '@EndDate',
这样您应该可以在 xml 输出中看到问题所在。
我希望这会有所帮助。
