mysql_insert_id()寻找上一次插入的id

例子：

 $query_batch = 'INSERT INTO table_change_log_batch (BatchTableName,BatchOperator,BatchComments,BatchCreationTime,BatchAction,BatchPrimaryKeyValue) 
               VALUES ("'.$table_name.'","'.$user.'","'.$BatchComments.'","'.$timeNow.'","EDIT","0")';
        
       
        mysql_query($query_batch);
        $select = mysql_insert_id();//$select[0]就是最后插入的id值了，mysql_insert_id()必须紧接在insert或者update之后执行
