mysql运行总计付款分组列，共享代码

I am trying to create a running total of payments for each portfolio of stocks/shares, where there are multiple stock purchase transactions for a given stock and portfolio, I need to group the stock into a single line of stock by grouping the quantity and payment for that line.

Table Schema and data below and query and results of query follow

CREATE TABLE `test` (
  `code` varchar(10) DEFAULT NULL,
  `portfolio` varchar(30) DEFAULT NULL,
  `pdate` date DEFAULT NULL,
  `dividend` decimal(12,2) DEFAULT NULL,
  `quantity` int(11) DEFAULT NULL,
  `payment` double(12,2) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

LOCK TABLES `test` WRITE;
/*!40000 ALTER TABLE `test` DISABLE KEYS */;
INSERT INTO `test` VALUES

Desired results, are as above except BLND being the only share having more than one transaction is grouped/summated as follows for quantity and payment (2 lines is summated to a single line)

    You can extend your existing query with another sub-query as follows.

    select
     @row_n := @row_n + 1 as row_n,
     row_num,
     code,
     portfolio,
     pdate,
     dividend,
     quantity,
     payment,
     balance
     from ( select
     @row_num := @row_num + 1 as row_num,
     code,
     portfolio,
     pdate,
     dividend,
     quantity,
     ceiling(dividend*quantity/100) as payment,
     @balance := ceiling(dividend*quantity/100) + if (@prev_pfl = portfolio,@balance,0) as balance,
     @prev_pfl := portfolio as prev_portfolio
    from ( select
     code,
     portfolio,
     pdate,
     dividend,
     sum(quantity) as quantity 
    from test
    group by portfolio, pdate,code, dividend
    order by portfolio, pdate,code, dividend ) as SubQueryAlias1
    cross join
    ( select @row_num := 0, @balance := 0, @prev_pfl := '' ) as InitVarsAlias1 
    order by portfolio, pdate,code) as SubQueryAlias2
    cross join 
    (select @row_n := 0 ) as InitVarsAlias2 
    order by pdate,portfolio,code,row_num;

    and it will provide you with the appropriate output as you requested.

    row_n   row_num     code    portfolio       pdate       dividend    quantity    payment     balance
