Question

我们有应用程序同步某些数据库（sqlserver）。技术人员数据库（SQLExpress 2008 32位）和服务器端SqlServer 2008 R2 64位。

在同步应用程序中我要对某些脚本进行同步。从技术人员到服务器的数据库。现在我收到类似[DBNETLIB] [ConnectionWrite（send（））的错误。]

我已经记录了错误

在日志中，脚本要进行更新。我还在sqlserver的命令提示中设置了一个永恒的ping。当脚本执行更新时，ping会超时。

此错误仅在我有移动宽带连接时才会出现。当技术人员到达公司然后笔记本电脑找到公司的wifi并且脚本可以完成。该错误仅在移动宽带连接中发生。

function TLogFile.SqlExec (StrSql : String; AdoConnection : TADOConnection; ARec: _RecordSet): Integer;
begin
  Result := 0;
  try
    ARec := AdoConnection.Execute(StrSql, cmdText);
  except
    on E : Exception do
    begin
      E.Message:= E.Message+ craConstant.CRLF+
                  'On script: '+StrSql+ craConstant.CRLF+
                  'Connection:'+ AdoConnection.Name;
      if (E.ClassType = EOleException) and (AdoConnection.Errors.Count > 0) then
      begin
        E.Message:= E.Message+ craConstant.CRLF+

      end;
      self.HndException:= E;
      Result := -1;

      raise;
    end;
  end;
end;

我在sqlexec函数中做了一些更改：

function TLogFile.SqlExec (StrSql : String; AdoConnection : TADOConnection): Integer;
var
  oQuerySql: TADOQuery;
begin
  Result := 0;

  oQuerySql:= TADOQuery.Create(Nil);
  try
    oQuerySql.Connection:= AdoConnection;
    oQuerySql.CommandTimeout:= AdoConnection.CommandTimeout;
    oQuerySql.SQL.Add(StrSql);

    try
      oQuerySql.ExecSQL;
    except
      on E : Exception do
      begin
        E.Message:= E.Message+ craConstant.CRLF+
                    'On script: '+StrSql+ craConstant.CRLF+
                    'Connection:'+ AdoConnection.Name;
        if (E.ClassType = EOleException) and (AdoConnection.Errors.Count > 0) then
        begin
          E.Message:= E.Message+ craConstant.CRLF+
                      'Number = '+IntToStr(AdoConnection.Errors[0].Number)+CRLF+
                      'NativeError = '+IntToStr(AdoConnection.Errors[0].NativeError)+CRLF+
                      'Source = '+AdoConnection.Errors[0].Source+CRLF+
                      'Description = '+AdoConnection.Errors[0].Description+CRLF+
                      'Helpfile = '+AdoConnection.Errors[0].HelpFile+CRLF+
                      'SQLState = '+AdoConnection.Errors[0].SQLState+CRLF+
                      'ConnectionTimeOut = '+IntToStr(AdoConnection.ConnectionTimeout) +CRLF+
                      'CommandTimeout = '+IntToStr(AdoConnection.CommandTimeout);
        end;
        self.HndException:= E;
        Result := -1;

        raise;
      end;
    end;
  finally
    FreeAndNil(oQuerySql);
  end;
end;

此更改在3天内没问题，现在我在

等插入脚本上找回错误

我找到了地板上的技术人员。我使用旧函数TLogFile.SqlExec（StrSql：String; AdoConnection：TADOConnection; ARec：_RecordSet）运行旧的同步应用程序：整数; 并且脚本不会给我一个错误。 AdoConnection.Execute（StrSql，cmdText）VS oQuerySql.ExecSQL有什么问题; adoconnection和脚本是在一个线程中完成的。

在较旧的笔记本电脑（Windows XP）上，我没有这个问题。仅适用于装有Windows7的新笔记本电脑。

如果有人可以给我一些澄清或提示在哪里搜索问题。我会很感激的。 “SQL Server Native Client 10.0”和“Microsoft OLE DB Provider for SQL Server”之间是否存在差异。

对于同步，我使用'Microsoft OLE DB Provider for SQL Server'

Answer 1

我向笔记本电脑公司（松下）提出这个问题。松下给我一个固件更新和驱动程序安装，这解决了这个问题。我不再收到网络错误了。
