Public Function ExecuteSQL(ByVal SQL As String, MsgString As String) As ADODB.Recordset
Dim cnn As ADODB.Connection
Dim rst As ADODB.Recordset
Dim sTokens() As String
On Error GoTo ExecuteSQL_Error

sTokens = Split(SQL)

Set cnn = New ADODB.Connection
cnn.Open ConnectString
If InStr("INSERT,DELETE,UPDATE,EXECUTE", UCase$(sTokens(0))) Then
cnn.Execute (SQL)
MsgString = sTokens(0) & " query successful"
Else
Set rst = New ADODB.Recordset
rst.Open Trim$(SQL), cnn, adOpenKeyset, adLockOptimistic
Set ExecuteSQL = rst
MsgString = "查询到" & rst.RecordCount & " 条记录 "
End If
ExecuteSQL_Exit:
Set rst = Nothing
Set cnn = Nothing
Exit Function


ExecuteSQL_Error:
MsgString = "查询错误: " & Err.Description
Resume ExecuteSQL_Exit
End Function

结果调试中 msgtext=“查询错误: [Microsoft][ODBC 驱动程序管理器] 未发现数据源名称并且未指定默认驱动程序”
请问是那里的问题，是SQL服务器？还是我的代码？
再线等！谢谢！
