确定使用ms-access的ODBC故障(错误3146)的真正原因? [英] Determine real cause of ODBC failure (error 3146) with ms-access?

问题描述

我的客户端使用Access作为SQL Server数据库的前端.他们最近开始不时产生ODBC-运行某些报告时会出现3146错误.据我所知，这只是一个通用的ODBC调用失败错误.

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.

我尝试在启动报告的VB脚本中保留一些错误处理，但是我没有运气获得额外的错误信息.

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.

代码看起来像这样.

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

我还启用了ODBC方面的跟踪功能，但是这使事情陷入了沉迷，到目前为止，我无法重新创建ODBC错误.

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.

我完全愿意就如何诊断这一问题提出建议.

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

推荐答案

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 DAO.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

要启用此代码，请确保在VBA设置中启用了错误处理.

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