Question

大家好，我正在努力获得2个查询的最终总和。

我将这笔款项以2013年的欧元计算。

这是我的查询http://sqlfiddle.com/#!2/a2638/14。

 JAN    FEB      MAR    APR     MAY     JUN      JUL    AUG     SEP     OCT     NOV     DEC
4900    4900    6400    6400    6400    6400    6400    6400    2400    2400    2400    2400

2013年我将这笔款项兑换成欧元。

这是我的查询http://sqlfiddle.com/#!2/a2638/15。

 JAN    FEB      MAR    APR     MAY      JUN    JUL      AUG    SEP      OCT    NOV DEC
15386   15386   20096   20096   20096   20096   20096   20096   7536    7536    7536    7536

我正试图得到这样的最终总和：

 JAN    FEB      MAR    APR     MAY      JUN    JUL      AUG    SEP      OCT    NOV DEC
20286   20286   26496   26496   26496   26496   26496   26496   9936    9936    9936    9936

以下是解释所有内容http://sqlfiddle.com/#!2/a2638/12

的查询

请有人帮助我吗？

我真的很感激帮助

Answer 1

从SqlFiddle剪切和粘贴：

    select a.Jan * @euro + b.Jan Jan,  a.Feb * @euro + b.Feb Feb.....
    from
    (
      SELECT
      SUM(if (CONCAT(@year, '-01') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance, 0)) Jan,
      SUM(if (CONCAT(@year, '-02') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance, 0)) Feb,
      ....
      1 as Id

      FROM insurances  i
      INNER JOIN policies p ON p.id = i.policy_id 
      WHERE (i.initial_date >= p.date_ini
         AND i.final_date   <= p.date_expired) 
         AND type_money = 1
    ) a
    inner join
    (
      SELECT
      SUM(if (CONCAT(@year, '-01') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance, 0) * @euro) Jan,
      SUM(if (CONCAT(@year, '-02') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance, 0) * @euro) Feb,
      ....
  1 as Id

  FROM insurances  i
  INNER JOIN policies p ON p.id = i.policy_id 
  WHERE (i.initial_date >= p.date_ini
     AND i.final_date   <= p.date_expired) 
     AND type_money = 1
) b on b.Id = a.Id

即。将两个查询放在一起;为每个字段添加一个Id字段，以便它们可以连接，并根据需要添加/乘法。

Answer 2

尝试运行：

SELECT 
SUM(if (CONCAT(@year, '-01') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance * IF (type_money = 2, @euro, 1), 0)) Jan,
SUM(if (CONCAT(@year, '-02') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance * IF (type_money = 2, @euro, 1), 0)) Feb,
SUM(if (CONCAT(@year, '-03') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance * IF (type_money = 2, @euro, 1), 0)) Mar,
SUM(if (CONCAT(@year, '-04') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance * IF (type_money = 2, @euro, 1), 0)) Apr,
SUM(if (CONCAT(@year, '-05') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance * IF (type_money = 2, @euro, 1), 0)) May,
SUM(if (CONCAT(@year, '-06') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance * IF (type_money = 2, @euro, 1), 0)) Jun,
SUM(if (CONCAT(@year, '-07') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance * IF (type_money = 2, @euro, 1), 0)) Jul,
SUM(if (CONCAT(@year, '-08') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance * IF (type_money = 2, @euro, 1), 0)) Aug,
SUM(if (CONCAT(@year, '-09') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance * IF (type_money = 2, @euro, 1), 0)) Sep,
SUM(if (CONCAT(@year, '-10') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance * IF (type_money = 2, @euro, 1), 0)) Oct,
SUM(if (CONCAT(@year, '-11') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance * IF (type_money = 2, @euro, 1), 0)) Nov,
SUM(if (CONCAT(@year, '-12') BETWEEN date_format(date_ini, '%Y-%m') AND date_format(date_expired, '%Y-%m'),i.net_insurance * IF (type_money = 2, @euro, 1), 0)) `Dec`

FROM insurances  i
INNER JOIN policies p ON p.id = i.policy_id 
WHERE (i.initial_date >= p.date_ini
AND i.final_date   <= p.date_expired) 
;

如果你有更多的货币，最好引入'货币表并添加它来加入。看看http://sqlfiddle.com/#!2/46cba/2
