我正在运行工资单报告,但无法查询并返回我需要的结果。在报告中,有两列,表格如下:
Date | Costs
2014 | 100000
2015 | 150000
但是,诀窍在于,有两种员工的成本会添加到“成本”列中。一种员工是正常的"他们的员工人数遵循" E00 ......"喜欢" E001,E002,E003等
第二种是经理。他们的员工数量类似于" E99 ...",所以" E990,E991等。
为了查询和返回“费用”列的数据,我目前收回了查询的100%员工费用。但是,我想查询并仅返回50%的E00类型员工以添加到“成本”列中,并且仅返回12.5%的E99类型员工以添加到“成本”列中。
通过这种方式,“成本”列将由添加50%的E00员工成本和增加12.5%的E99员工成本组成。
以下是我的查询,但我无法让它返回任何内容:
select
to_char("Date", 'YYYY') as "Date",
case
when "Type" in ('E001', 'E002', 'E003', 'E004') then 0.5 * sum ("Amount") filter (where "Type" in ('E001', 'E002', 'E003', 'E004'))
when "Type" like 'E9%' then 0.125 * sum("Amount") filter (where "Type" like 'E9%')
end as "Costs"
from "Transactions"
group by 1
order by min("Date");
答案 0 :(得分:1)
为什么不这样呢?
SELECT mydate,
SUM(mysum)
FROM (
(SELECT to_char("Date", 'YYYY') AS mydate,
0.5 * SUM("Amount") AS mysum
FROM "Transactions"
WHERE TYPE LIKE 'E00%'
GROUP BY 1)
UNION ALL
(SELECT to_char("Date", 'YYYY') AS mydate,
0.125 * SUM("Amount")
FROM "Transactions"
WHERE TYPE LIKE 'E9%'
GROUP BY 1)) s1
GROUP BY mydate
ORDER BY mydate;
