php - mysql运行按列分组的付款总额，共享代码

标签 php html mysql

我正在尝试为每个股票/股票投资组合创建连续的付款总额，其中给定股票和投资组合有多个股票购买交易，我需要通过将股票分组为单行股票该行的数量和付款。

下面的表架构和数据以及查询和查询结果

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

下面显示查询，后跟结果

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 test
cross join
( select @row_num := 0, @balance := 0, @prev_pfl := '' ) as InitVarsAlias 
order by portfolio, pdate,code) as SubQueryAlias
cross join 
(select @row_n := 0 ) as InitVarsAlias2 
order by pdate,portfolio,code,row_num;

查询结果，后面是期望的结果

期望的结果如上所述，但 BLND 是唯一具有多于一笔交易的股票，数量和付款按如下方式分组/汇总(2 行汇总为单行)

您可以使用另一个子查询来扩展现有查询，如下所示。

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;

它将根据您的要求提供适当的输出。

row_n   row_num     code    portfolio       pdate       dividend    quantity    payment     balance
