给mysql查询添加序号列

select *,(@number := @number+1) AS number from
        (select u.mobile,u.`name`, ROUND((select  sum(r.realAmount) from t_recharge r where r.userid=u.id and  r.status=\'1\' ),2)rechargeSum,           
        ROUND((select  sum(w.realAmount) from t_withdrawal w where w.userid=u.id and  w.status=\'1\' ),2)withdrawalSum,          
        ROUND(sum(f.ownAmount),2)ownAmountSum,          
        ROUND(sum(f.platformFunds),2)platformFundsSum,          
        ROUND((select sum(fd.amount) from t_fund_detail fd where fd.userid=u.id and fd.type=\'3\' ),2)feeSum,             
        ROUND(sum(f.result),2) cashResult ,
        u.balance,u2.`name` as froms               
         from t_user u
        left join t_financing f on f.userid=u.id
        LEFT JOIN t_user u2 ON u2.id = u.fromId
        group by u.id ) temp ,(select @number :=0) b  

用到的是(@number := @number+1) AS number和(select @number :=0) b  ，上面是多个表的例子

但个表的例子如下：
