我目前正在编写一些代码,可以通过 ADODB 连接访问单独的工作簿。由于速度的原因,我选择了这个而不是其他方法。下面是我的代码:
Sub GetWorksheetData(strSourceFile As String, strSQL As String, TargetCell As range)
Dim cn As ADODB.Connection, rs As ADODB.Recordset, f As Integer, r As Long
If TargetCell Is Nothing Then Exit Sub
Set cn = New ADODB.Connection
On Error Resume Next
cn.Open "DRIVER={Microsoft Excel Driver (*.xls)};DriverId=790;ReadOnly=True;" & _
"DBQ=" & strSourceFile & ";"
' DriverId=790: Excel 97/2000
' DriverId=22: Excel 5/95
' DriverId=278: Excel 4
' DriverId=534: Excel 3
On Error GoTo 0
If cn Is Nothing Then
MsgBox "Can't find the file!", vbExclamation, ThisWorkbook.Name
Exit Sub
End If
' open a recordset
Set rs = New ADODB.Recordset
On Error Resume Next
rs.Open strSQL, cn, adOpenForwardOnly, adLockReadOnly, adCmdText
' rs.Open "SELECT * FROM [SheetName$]", _
cn, adOpenForwardOnly, adLockReadOnly, adCmdText
' rs.Open "SELECT * FROM [SheetName$]", _
cn, adOpenStatic, adLockOptimistic, adCmdText
' rs.Open "SELECT * FROM [SheetName$] WHERE [Field Name] LIKE 'A%'", _
cn, adOpenStatic, adLockOptimistic, adCmdText
' rs.Open "SELECT * FROM [SheetName$] WHERE [Field Name] LIKE 'A%' ORDER BY [Field Name]", _
cn, adOpenStatic, adLockOptimistic, adCmdText
' optional ways of retrieving a recordset
' Set rs = cn.Execute("[A1:Z1000]") ' first worksheet
' Set rs = cn.Execute("[DefinedRangeName]") ' any worksheet
On Error GoTo 0
If rs Is Nothing Then
MsgBox "Can't open the file!", vbExclamation, ThisWorkbook.Name
cn.Close
Set cn = Nothing
Exit Sub
End If
'RS2WS rs, TargetCell
TargetCell.CopyFromRecordset rs ' optional approach for Excel 2000 or later
If rs.State = adStateOpen Then
rs.Close
End If
Set rs = Nothing
cn.Close
Set cn = Nothing
End Sub
现在,这段代码大部分都有效,但是当一行包含混合数据类型时,查询将跳过一些值。例如:
原始数据:
3844774 12505604
3844794 12505604
4266113 3281271
4295817 1307HX
返回数据:
3844774 12505604
3844794 12505604
4266113 3281271
4295817
注意最后一位数据是如何被跳过的。这适用于多个条目,但仅限于包含字母的条目(使其成为文本)。原始表格也将所有内容都设置为文本。有什么建议让它不会跳过这些行吗?
提前致谢!
