Question

我有以下代码

    using (OracleConnection srcConn = new OracleConnection())
    using (OracleConnection destConn = new OracleConnection())
    {
      srcConn.ConnectionString = AppInfo.SrcConnStr;
      srcConn.Open();
      destConn.ConnectionString = AppInfo.DestConnStr;
      destConn.Open();

      using (OracleCommand destCmd = new OracleCommand("ALTER SESSION SET NLS_DATE_FORMAT = 'yyyy-mm-dd hh24:mi:ss'", destConn))
      using (OracleCommand srcCmd = new OracleCommand("ALTER SESSION SET NLS_DATE_FORMAT = 'yyyy-mm-dd hh24:mi:ss'", srcConn))
      {

        // Non-query
        srcCmd.ExecuteNonQuery();
        destCmd.ExecuteNonQuery();
        if (Timing) { ut.TimeIt(stopwatch, "Get Connection and Command"); }

        srcCmd.CommandTimeout = 0;
        destCmd.CommandTimeout = 0;

        srcCmd.CommandText = "select * from table_name";
        rd = srcCmd.ExecuteReader();
        rd.FetchSize = rd.RowSize * AppInfo.BatchSize; }

        OracleBulkCopy copy = new OracleBulkCopy(destConn);
        copy.DestinationTableName = DestTable;
        copy.BatchSize = AppInfo.BatchSize;
        copy.NotifyAfter = AppInfo.BatchSize;
        copy.OracleRowsCopied += new OracleRowsCopiedEventHandler(OnOracleRowsCopied);
        copy.BulkCopyTimeout = AppInfo.CommandTimeOut;
        copy.WriteToServer(rd);

      }
    }

什么时候复制.WriteToServer（rd）;它给出了以下错误

 System.ArgumentException was caught
 Message='0' is not a valid value for 'Interval'. 'Interval' must be greater than 0.
 Source=System
 StackTrace:
   at System.Timers.Timer.set_Interval(Double value)
   at Oracle.DataAccess.Client.OracleBulkCopy.PerformBulkCopy()
   at Oracle.DataAccess.Client.OracleBulkCopy.WriteDataSourceToServer()
   at Oracle.DataAccess.Client.OracleBulkCopy.WriteToServer(IDataReader reader)

我的问题是，我该如何解决？

感谢任何帮助。

问题可能是将CommandTimeout设置为零。尝试一个合理的数字。我认为这是在几秒钟内指定的。

OracleBulkCopy错误：'0'不是'Interval'的有效值
