mysql如何在一行上显示每个投资组合、股票的值答案

【问题标题】：mysql how to display values on one row for each portfolio, stockmysql如何在一行上显示每个投资组合、股票的值

【问题描述】：

我需要为每个投资组合/股票组合显示一行，显示每个月的付款，因此如果一家公司在 5 月和 9 月分别支付 441 和 215 每年两次，这将显示在一行中。目前我的查询为每次付款输出一行，列 Jan - Dec

我尝试使用子查询无济于事，我对如何实现这一点没有任何想法。

SELECT
    s.symbol AS Symbol,
    p.code AS Portfolio,
    (case when ANY_VALUE(DATE_FORMAT(d.pdate,'%b')) = 'Jan' then IFNULL(CEILING((SUM(IF(t.transaction_type='Buy',t.quantity,t.quantity * -1)) * ANY_VALUE(d.dividend) ) / 100),0) end) AS Jan,
    (case when ANY_VALUE(DATE_FORMAT(d.pdate,'%b')) = 'Feb' then IFNULL(CEILING((SUM(IF(t.transaction_type='Buy',t.quantity,t.quantity * -1)) * ANY_VALUE(d.dividend) ) / 100),0) end) AS Feb,
    (case when ANY_VALUE(DATE_FORMAT(d.pdate,'%b')) = 'Mar' then IFNULL(CEILING((SUM(IF(t.transaction_type='Buy',t.quantity,t.quantity * -1)) * ANY_VALUE(d.dividend) ) / 100),0) end) AS Mar,
    (case when ANY_VALUE(DATE_FORMAT(d.pdate,'%b')) = 'Apr' then IFNULL(CEILING((SUM(IF(t.transaction_type='Buy',t.quantity,t.quantity * -1)) * ANY_VALUE(d.dividend) ) / 100),0) end) AS Apr,
    (case when ANY_VALUE(DATE_FORMAT(d.pdate,'%b')) = 'May' then IFNULL(CEILING((SUM(IF(t.transaction_type='Buy',t.quantity,t.quantity * -1)) * ANY_VALUE(d.dividend) ) / 100),0) end) AS May,
    (case when ANY_VALUE(DATE_FORMAT(d.pdate,'%b')) = 'Jun' then IFNULL(CEILING((SUM(IF(t.transaction_type='Buy',t.quantity,t.quantity * -1)) * ANY_VALUE(d.dividend) ) / 100),0) end) AS Jun,
    (case when ANY_VALUE(DATE_FORMAT(d.pdate,'%b')) = 'Jul' then IFNULL(CEILING((SUM(IF(t.transaction_type='Buy',t.quantity,t.quantity * -1)) * ANY_VALUE(d.dividend) ) / 100),0) end) AS Jul,
    (case when ANY_VALUE(DATE_FORMAT(d.pdate,'%b')) = 'Aug' then IFNULL(CEILING((SUM(IF(t.transaction_type='Buy',t.quantity,t.quantity * -1)) * ANY_VALUE(d.dividend) ) / 100),0) end) AS Aug,
    (case when ANY_VALUE(DATE_FORMAT(d.pdate,'%b')) = 'Sep' then IFNULL(CEILING((SUM(IF(t.transaction_type='Buy',t.quantity,t.quantity * -1)) * ANY_VALUE(d.dividend) ) / 100),0) end) AS Sep,
    (case when ANY_VALUE(DATE_FORMAT(d.pdate,'%b')) = 'Oct' then IFNULL(CEILING((SUM(IF(t.transaction_type='Buy',t.quantity,t.quantity * -1)) * ANY_VALUE(d.dividend) ) / 100),0) end) AS Oct,
    (case when ANY_VALUE(DATE_FORMAT(d.pdate,'%b')) = 'Nov' then IFNULL(CEILING((SUM(IF(t.transaction_type='Buy',t.quantity,t.quantity * -1)) * ANY_VALUE(d.dividend) ) / 100),0) end) AS Nov

    FROM
    dm_transactions t
    INNER JOIN dm_dividends d ON (d.stock_id = t.stock_id)
    INNER JOIN dm_stocks s ON (s.id = t.stock_id) 
    INNER JOIN dm_portfolios p ON (t.portfolio_id = p.id)
    WHERE
    ANY_VALUE(d.pdate) >= CURDATE()
    AND
    p.code = 'SFT_DEA_CO'
    AND
    s.symbol = 'AV..L'
    AND
    t.user_id =2
    GROUP BY
    s.symbol, d.pdate

输出

Symbol Portfolio  Jan  Feb  Mar  Apr  May  Jun  Jul  Aug  Sep  Oct 
AV..L  SFT_DEA_CO NULL NULL NULL NULL 441  NULL NULL NULL NULL NULL 
AV..L  SFT_DEA_CO NULL NULL NULL NULL NULL NULL NULL NULL 215  NULL

下面需要的输出

Symbol Portfolio  Jan  Feb  Mar  Apr  May  Jun  Jul  Aug  Sep  Oct 
AV..L  SFT_DEA_CO                     441                 215

对于给定的交易品种、投资组合，我需要一行并且没有 NULL 值。

非常感谢任何帮助。

谢谢

您可以在子查询上使用聚合函数

select  t.Symbol, t.Portfolio
  , max(Jan)
  , max(feb)
  , max(Mar)
  , max(Apr)
  , max(May)
  , max(Jun)
  , max(Jul)
  , max(Aug)
  , max(Sep)
  , max(Oct)
  , max(Nov)
from  (
  SELECT
  s.symbol AS Symbol,
  p.code AS Portfolio,
  (case when ANY_VALUE(DATE_FORMAT(d.pdate,'%b')) = 'Jan' then IFNULL(CEILING((SUM(IF(t.transaction_type='Buy',t.quantity,t.quantity * -1)) * ANY_VALUE(d.dividend) ) / 100),0) end) AS Jan,
  (case when ANY_VALUE(DATE_FORMAT(d.pdate,'%b')) = 'Feb' then IFNULL(CEILING((SUM(IF(t.transaction_type='Buy',t.quantity,t.quantity * -1)) * ANY_VALUE(d.dividend) ) / 100),0) end) AS Feb,
  (case when ANY_VALUE(DATE_FORMAT(d.pdate,'%b')) = 'Mar' then IFNULL(CEILING((SUM(IF(t.transaction_type='Buy',t.quantity,t.quantity * -1)) * ANY_VALUE(d.dividend) ) / 100),0) end) AS Mar,
