ANSI SQL 按（印度）财政年度 YTD 分组 - （过去 5 年 YTD）

Question

谁能指出如何对印度财政（4 月至 3 月）截至今天（过去 5 年）的数据进行分组。例如，我需要从表 'aaa' 中提取过去 5 年从 4 月 1 日到今天的日期中的 'field1'、'field2'。我目前的解决方案可以安全运行到 12 月，但稍后会出错

SELECT
         "Date",
         "Daily data",
         "ID",
         "GA%",
         "MA%"
FROM  "table" 
WHERE    month("Date")  >= 4
 AND    month("Date")  <= month(today())
 AND    date("Date")  < date(today())

Expected result format grouped by fiscal years:
FY-1 sum(daily data during the period) sum(GA) sum(MA)
FY-2 sum(daily data during the period) sum(GA) sum(MA)

Answer 1

SELECT
         "Date",
         "Daily data",
         "ID",
         "GA%",
         "MA%"
FROM  "table" 
WHERE    
"Date" between '2021-04-01' and '2021-11-29'
OR
"Date" between '2020-04-01' and '2020-11-29'
OR
"Date" between '2019-04-01' and '2019-11-29'
OR
"Date" between '2018-04-01' and '2018-11-29'
OR
"Date" between '2017-04-01' and '2017-11-29'

未经测试的记事本涂鸦

SELECT
  MIN(`Date`) AS StartDate
, MAX(`Date`) AS EndDate
, COUNT(ID) AS CountId
, SUM(`GA%`) AS `TotalGa%`
, SUM(`MA%`) AS `TotalMa%`
FROM `table` AS aaa
WHERE 
(
  (YEAR(`Date`) BETWEEN YEAR(CURRENT_DATE) - 4 AND YEAR(CURRENT_DATE) - 1) 
  OR 
  (YEAR(`Date`) = YEAR(CURRENT_DATE) AND MONTH(`Date`) <= 11)
  OR
  (YEAR(`Date`) = YEAR(CURRENT_DATE) - 5 AND MONTH(`Date`) > 3)
)
AND 
(
    MONTH(`Date`) NOT IN (12, 1, 2, 3)
    OR
    YEAR(`Date`) = YEAR(CURRENT_DATE)
) 
GROUP BY CASE WHEN MONTH(`Date`) <= 3 THEN YEAR(`Date`) - 1
              ELSE YEAR(`Date`) END
ORDER BY MIN(`Date`) DESC
