                         bulkCopy.DestinationTableName = tableName;//要插入的表的表名
                         bulkCopy.BatchSize = dt.Rows.Count;
                         bulkCopy.ColumnMappings.Add("ID", "ID");//映射字段名 DataTable列名 ,数据库 对应的列名  
                         bulkCopy.ColumnMappings.Add("primaryDataID", "primaryDataID");
                         bulkCopy.ColumnMappings.Add("SysKeywordID", "SysKeywordID");
