如何解决VBA代码中的SQL查询？

标签： sql vba ms-access

我制作了一条SQL语句，用于计算我收集的所选字段的总和。我的查询在MS Access中运行，但是当我将其转换为数据库中的VBA编码时，它会吐出编译错误：语法错误。在下面，我附加了我的工作查询以及使用语法的查询。

MS Access中的查询在下面可以正常使用：

SELECT 1,'Passed - Depot' AS QRY, Sum(IIf(([PreStressStackDate]>=[StartDate] And [PreStressStackDate]<=[EndDate]) And (([CurrentLevelOfCompletion]>=5 And [CurrentLevelOfCompletion]<1073741829) Or [CurrentLevelOfCompletion]>1073741829),1,0)) AS [PreStress Stackup], Sum(IIf(([StackCompressionDate]>=[StartDate] And [StackCompressionDate]<=[EndDate]) And (([CurrentLevelOfCompletion]>=21 And [CurrentLevelOfCompletion]<1073741845) Or [CurrentLevelOfCompletion]>1073741845),1,0)) AS [Stack Compression], Sum(IIf(([TestingDate]>=[StartDate] And [TestingDate]<=[EndDate]) And (([CurrentLevelOfCompletion]>85 And [CurrentLevelOfCompletion]<1073741909) Or [CurrentLevelOfCompletion]>1073741909),1,0)) AS Testing, Sum(IIf(([ShroudAssemblyDate]>=[StartDate] And [ShroudAssemblyDate]<=[EndDate]) And (([CurrentLevelOfCompletion]>=341 And [CurrentLevelOfCompletion]<1073742165) Or [CurrentLevelOfCompletion]>1073742165),1,0)) AS [Shroud Assembly], Sum(IIf(([TransformerInstallDate]>=[StartDate] And [TransformerInstallDate]<=[EndDate]) And (([CurrentLevelOfCompletion]>=1365 And [CurrentLevelOfCompletion]<1073743189)),1,0)) AS [Transformer Installation]
FROM TR343DrySide
WHERE (([TransducerSN] Not Like "CR*"));

UNION SELECT 2, 'Failed - Depot' AS QRY, Sum(IIf(([PreStressStackDate]>=[StartDate] And [PreStressStackDate]<=[EndDate]) And [CurrentLevelOfCompletion]=1073741829,1,0)) AS [PreStress Stackup], Sum(IIf(([StackCompressionDate]>=[StartDate] And [StackCompressionDate]<=[EndDate]) And [CurrentLevelOfCompletion]=1073741845,1,0)) AS [Stack Compression], Sum(IIf(([TestingDate]>=[StartDate] And [TestingDate]<=[EndDate]) And [CurrentLevelOfCompletion]=1073741909,1,0)) AS [Testing], Sum(IIf(([ShroudAssemblyDate]>=[StartDate] And [ShroudAssemblyDate]<=[EndDate]) And [CurrentLevelOfCompletion]=1073742165,1,0)) AS [Shroud Assembly], Sum(IIf(([TransformerInstallDate]>=[StartDate] And [TransformerInstallDate]<=[EndDate]) And [CurrentLevelOfCompletion]=1073743189,1,0)) AS [Transformer Installation]
FROM TR343DrySide
WHERE (([TransducerSN] Not Like "CR*"));

运行此查询时，它会汇总所选日期之间的字段总和。

下面，我附加了带有语法编译错误的VBA代码：

Private Sub cmdDrySideRunReport_Click()

    Dim strDrySQL_New, strDrySQL_Depot       As String
    Dim DryStartDate                         As Date
    Dim DryEndDate                           As Date


  '------------------------------------------------------------------------------------------------------
  If IsNull(Me.txtDryStartDate) Or Me.txtDryStartDate = "" Or IsNull(Me.txtDryEndDate) Or Me.txtDryEndDate = "" Then
        If IsNull(Me.txtDryStartDate) Or Me.txtDryStartDate = "" Then
            MsgBox "Please enter the Start Date"
            Me.txtDryStartDate.SetFocus
        End If
        If IsNull(Me.txtDryEndDate) Or Me.txtDryEndDate = "" Then
            MsgBox "Please enter the End Date"
            Me.txtDryEndDate.SetFocus
        End If
    Else
        DryStartDate = Me.txtDryStartDate
        DryEndDate = Me.txtDryEndDate + 1

我相信该语句中会发生错误：

  "Sum(IIf(([TestingDate]>=#" & StartDate & "# And [TestingDate]<=#" & EndDate & "#) &" _
                        " And [CurrentLevelOfCompletion]=1073741909,1,0)) AS [Testing], Sum(IIf(([ShroudAssemblyDate]>=#" & StartDate & "# And [ShroudAssemblyDate]<=#" & EndDate & "#)" & _
                        " And [CurrentLevelOfCompletion]=1073742165,1,0)) AS [Shroud Assembly],"

1 个答案:

答案 0 :(得分：1)

您的字符串不好，并且在这些行中由于字符串中有流氓"而变得无效：

" And [CurrentLevelOfCompletion]=1073741909,1,0)) AS [Testing]", Sum(IIf(([ShroudAssemblyDate]>=#" & StartDate & "# And [ShroudAssemblyDate]<=#" & EndDate & "#)" & _

" And [CurrentLevelOfCompletion]=1073742165,1,0)) AS [Shroud Assembly]", Sum(IIf(([TransformerInstallDate]>=#" & StartDate & "# And [TransformerInstallDate]<=#" & EndDate & "#)" & _
像这样的

MultiLine字符串分配应该用于使代码更具可读性。就您的情况而言，我认为这使内容的可读性和故障排除更加困难。我建议从此sql中构建查询对象，而不是在VBA中构建字符串。仅出于故障排除的目的，如果必须在vba中构建它-请使用结构化，自连接的方式构建字符串。以这种方式查看编译错误要容易得多。

以上代码实际上将debug.print格式化良好的SQL语句；轻松解决问题
