我正在尝试使用VBA和ADO选项从另一个文件查询Excel文件。当我运行此代码时,它会抛出错误“无法更新,数据库或对象只读”:

Public Function fnExecuteXlQuery _
    (ByVal strPath As String,  _
    ByVal strQuery As String) As ADODB.Recordset

Dim rs As ADODB.Recordset
Dim conStr As String

On Error GoTo ErrorHandler

conStr = "Provider=Microsoft.Jet.OLEDB.4.0; " _ 
      & "Data Source=" & strPath & "; Extended Properties=Excel 8.0"

Set rs = New ADODB.Recordset
rs.Open strQuery, conStr, adOpenDynamic

Set fnExecuteXlQuery = rs

Exit Function
ErrorHandler:
Set fnExecuteXlQuery = Nothing
fnDisplayError Error(Err) & "Unable to fetch data from DTS...", ERROR_TYPE_ERROR
End Function

strPath ”是源Excel文件,“ strquery ”具有以下SQL代码:

Select [Activity],[Name],[Date],[Hours Spent] 
from [Time sheet$] 
where [Activity] = 'Billable Activities' 
Order by Name,date

答案 0 :(得分:1)

也许所有评论中所说的内容都需要再次写出来,以确保您真正得到解决方案:

Option Explicit

Public Sub ConnectionToExcel()
Dim rstResult As ADODB.Recordset
Dim strConnectin As String
Dim strPath As String
Dim strSQL As String

strPath = "C:\Data\YourFile.xlsm"

strConnectin = "Provider=Microsoft.ACE.OLEDB.12.0;" & _
    "Data Source='" & strPath & "';Extended Properties=""Excel 12.0 XML;HDR=YES;IMEX=1"" "
Debug.Print strConnection

strSQL = "SELECT * FROM [Time sheet$] "

Set rstResult = New ADODB.Recordset
rstResult.Open strSQL, strConnectin, adOpenForwardOnly, adLockReadOnly, adCmdText

Sheet1.Range("A1").CopyFromRecordset rstResult

End Sub

请注意,我一步一步:(1)我使用的是sub而不是功能。 (2)select已经简化为测试连接,可以稍后扩展。 (3)只需将结果写回第一张纸。 (4)进一步限制记录集仅限adOpenForwardOnlyadLockReadOnly

此外,请注意,上述代码使用早期绑定,因此您需要在Microsoft ActiveX Data Objects 2.8 Library - >中设置对Tools(或更晚)的引用。 References...
