使用ms-access确定ODBC失败的真正原因（错误3146）？

My client is using Access as a front end to a SQL Server database. They recently started getting ODBC - 3146 errors from time to time when running some reports. From what I can tell, this is just a generic ODBC call failed error.

我的客户端使用Access作为SQL Server数据库的前端。他们最近在运行一些报告时不时开始收到ODBC-3146错误。据我所知,这只是一个通用的ODBC调用失败错误。

I've tried sticking some error handling in the VB script that is launching the reports, but I am not having any luck getting extra error information.

我已经尝试在启动报告的VB脚本中坚持一些错误处理,但我没有运气获得额外的错误信息。

Code looks a bit like this.

代码看起来有点像这样。

Public Function RunReports()
  On Error GoTo MyErrorTrap

  DoCmd.OpenReport "blah", acViewPreview
  DoCmd.Close

  DoCmd.OpenReport "foo", acViewPreview
  DoCmd.Close

Exit_function:
  Exit Function

MyErrorTrap:
  Dim errX As DAO.Error
  Dim MyError As Error
  If Errors.Count > 1   'This always seems to be 0, so no help
    For Each errX In DAO.Errors  'These are empty even if dont check for Errors.Count
      Debug.Print "ODBC Error"
      Debug.Print errX.Number
      Debug.Print errX.Description
    Next errX
  Else
    Debug.Print "VBA Error"
    Debug.Print Err.Number
    Debug.Print Err.Description
  End If

  'Also have tried checking DBEngine.Errors, but this is empty too

End Function

I've also enabled tracing on the ODBC side, but that has bogged things down way too much, and I am so far unable to recreate the ODBC error.

我还在ODBC端启用了跟踪,但这已经让事情陷入困境,我到目前为止无法重新创建ODBC错误。

I am completely open for suggestions on how to diagnose this.

我完全愿意接受有关如何诊断这一问题的建议。

Use the DbEngine.Errors collection.

使用DbEngine.Errors集合。

Sub Update_Temp()
On Error GoTo ErrorTrap
    ' Execute connect code at this point
Exit_errortrap:
    Exit Sub
ErrorTrap:
    Dim myerror As Error
    For Each myerror In DBEngine.Errors
        With myerror
            If .Number <> 3146 Then
                MsgBox .Description
            End If
        End With
    Next
    Resume Exit_errortrap

End Sub

To enable this code, make sure in VBA settings that error handling is turned on.

要启用此代码,请确保在VBA设置中启用了错误处理。
