如何求和来自2个查询的值？

Question

大家好，我正试图得到2个查询的最终总和。

我对欧元这笔款项与2013年

这里是我的查询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 

我有这样的总和dolars以欧元，2013年

这里是我的查询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 

我试图让dolars的这样一个最后的总和：

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

下面是查询解释一切http://sqlfiddle.com/#!2/a2638/12

请有人可以帮助我吗？

我会很感激帮助从SqlFiddle

尝试运行此：

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) 
; 

如果你将有更多的货币最好是introducee“货币表，并将其添加到加入。看看http://sqlfiddle.com/#!2/46cba/2

Answer 2

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 

即把两个查询一起;为每个ID添加一个Id字段，以便他们可以加入，并根据需要添加/乘法。
