通过VBA将日期格式更改为SQL查询

Question

我有一个我无法回答的问题，我的问题是我有一个使用SQL查找来访问SQL数据库并提取信息的宏。在excel中，总是将日期强制为DD / MM / YYYY（你可以强制格式化，但是当它传递到SQL方面时它仍然以DD / MM / YYYY形式出现，即使格式在视觉上看起来正确）。

我已尝试对我的代码进行一些更改以尝试“强制”它但是我没有运气我是否使其复杂化或是否应该更难做到这一点？洛尔。

我将提供我的VB代码和“属性”，以了解使用宏创建的“连接”。

作为一个注释，格式需要是YYYY-MM-DD，因为这是它存储在数据库中的方式。目前解决这个问题的唯一方法就是使用日期前面的“'”（例如'2013-12-01）强制它，否则它将转到2013年12月1日。

有什么想法吗？我一直在绞尽脑力lol。

如果需要该信息，则服务器是SQLEXPRESS服务器。

以下代码：

Sub CustomisedSQLQuery()
'
' SQL Query to allow user customisation. 
'

'
Dim FileName As String
Dim User As String
Dim StartDate As String
Dim EndDate As String
Dim Category As String


Dim Confirm As Variant
Confirm = MsgBox("Have you made sure that at least one of the search criteria's is populated? If so your excel may crash or you may kill the database.", vbQuestion + vbYesNo, "Wait....")
If Confirm = vbNo Then ActiveWorkbook.Sheets("Input Sheet").Activate
If Confirm = vbNo Then Exit Sub



FileName = Worksheets("Input Sheet").Cells(10, 1)
User = Worksheets("Master DATA").Cells(1, 1)
StartDate = Worksheets("Input Sheet").Cells(10, 3)
EndDate = Worksheets("Input Sheet").Cells(10, 4)
Category = Worksheets("Master DATA").Cells(1, 5)

MyStr = Format(StartDate, "yyyy/mm/dd")
MyStr = Format(EndDate, "yyyy/mm/dd")

    Sheets("Output Sheet").Select
    Cells.Select
    Selection.ClearContents
    Range("A1").Select
    With ActiveSheet.ListObjects.Add(SourceType:=0, Source:= _
        "ODBC;DRIVER=SQL Server;SERVER=SERVERADDRESS;UID=USERNAME;PWD=PASSWORD;APP=Microsoft Office 2010;WSID=ID" _
        , Destination:=Range("$A$1")).QueryTable
        .CommandText = Array( _
        "SELECT DocumentsRead.userID, DocumentsRead.fileName, DocumentsRead.category, DocumentsRead.downloadedByUser, DocumentsRead.timeDownloaded, DocumentsRead.timeR" _
        , _
        "ead" & Chr(13) & "" & Chr(10) & "FROM EndUsers.dbo.DocumentsRead DocumentsRead" & Chr(13) & "" & Chr(10) & "WHERE (DocumentsRead.fileName Like '" & FileName & "') AND (DocumentsRead.category='" & Category & "') AND (DocumentsRead.timeRead Is Null) " _
        , "AND (DocumentsRead.timeDownloaded Between {ts '" & StartDate & " 00:00:01'} An" _
        , "d {ts '" & EndDate & " 00:00:01'})")
        .RowNumbers = False
        .FillAdjacentFormulas = False
        .PreserveFormatting = True
        .RefreshOnFileOpen = False
        .BackgroundQuery = True
        .RefreshStyle = xlInsertDeleteCells
        .SavePassword = False
        .SaveData = True
        .AdjustColumnWidth = True
        .RefreshPeriod = 0
        .PreserveColumnInfo = True
        .Refresh BackgroundQuery:=False
    End With

Sheets("Input Sheet").Select
End Sub

这是SQL

的连接属性

SELECT DocumentsRead.userID, DocumentsRead.fileName, DocumentsRead.category, DocumentsRead.downloadedByUser, DocumentsRead.timeDownloaded, DocumentsRead.timeRead
FROM EndUsers.dbo.DocumentsRead DocumentsRead
WHERE (DocumentsRead.fileName Like 'GB') AND (DocumentsRead.category='Notices') AND (DocumentsRead.timeRead Is Null) AND (DocumentsRead.timeDownloaded Between {ts '01/12/2013 00:00:01'} And {ts '08/11/2013 00:00:01'})

输入表格如下：

看起来您的问题在于StartDate / EndDate的格式。这是你的代码：

MyStr = Format(StartDate, "yyyy/mm/dd")
MyStr = Format(EndDate, "yyyy/mm/dd")

以下是我想你要做的事情：

StartDate = Format(StartDate, "yyyy-mm-dd")
EndDate = Format(EndDate, "yyyy-mm-dd")

我相信你也可以告诉Access字符串是一个日期，将它包装在＃中。如

"and DocumentsRead.timeDownloaded >= #" & StartDate & "#" & vbcrlf & _
"and DocumentsRead.timeDownloaded <  #" & EndDate & "#"
