SQL批量复制中的异常和内存问题

Question

我们使用SQL批量复制将近1000万行插入到SQL Server表中.

我们在7400000次插入后收到此例外:

链接服务器'(null)'的OLE DB提供程序'STREAM'返回列'[!BulkInsert] .Amount'的无效数据.

如果可以解决,请告诉我们.

还有内存泄漏问题.

以下是我们的代码:

try
{
            using (SqlConnection SQlConn = new SqlConnection(Common.SQLConnectionString))
            {                   
                DataTable dt1 = FillEmptyDateFields(dtDestination);

                //SqlTableCreator ObjTbl = new SqlTableCreator(SQlConn);

                //ObjTbl.DestinationTableName = DestinationTable;

                using (System.Data.SqlClient.SqlBulkCopy bulkCopy = new System.Data.SqlClient.SqlBulkCopy(SQlConn,SqlBulkCopyOptions.TableLock,null))
                {

                    //bulkCopy = new System.Data.SqlClient.SqlBulkCopy(SQlConn);
                    bulkCopy.DestinationTableName = DestinationTable;
                    bulkCopy.BulkCopyTimeout = 0;
                    bulkCopy.BatchSize = dt1.Rows.Count; // Batch Size Added.
                    Logger.Log("DATATABLE FINAL :" + dt1.Rows.Count.ToString(), Logger.LogType.Info);
                    if (SQlConn.State == ConnectionState.Closed || SQlConn.State == ConnectionState.Broken)
                        SQlConn.Open();
                    bulkCopy.WriteToServer(dt1);
                    SQlConn.Close();
                    SQlConn.Dispose();
                    bulkCopy.Close();
                    if (bulkCopy != null)
                    {
                        ((IDisposable)bulkCopy).Dispose();
                    }                        
                }
                dt1.Dispose(); 
                dt1 = null;                           
            }

            dtDestination.Dispose();
            System.GC.Collect();
            dtDestination = null;                

}
catch (Exception ex)
{
    Logger.Log(ex, Logger.LogType.Error);
    throw ex;
}

根据您的代码，您似乎将 BatchSize 设置为数据表的大小，大概是 1000 万行。您可能想尝试使用 5000 之类的值。
