我的表中有以下数据
ID code date amount health_plan 111 A123 20170101 10 BH 111 A123 20100101 -10 BH 311 A124 20170712 20 CVA 311 A124 20170712 -20 CVA 311 A124 20170712 20 CVA 311 A124 20180201 55 CVA
我创建一个查询来显示那些对同一ID,代码和日期都有正值和负值的记录。运行以下查询后,我期待这种类型的输出。
111 A123 20170101 10 BH 111 A123 20100101 -10 BH 311 A124 20170712 20 CVA 311 A124 20170712 -20 CVA
WITH amt_cur
AS (SELECT DISTINCT first_name,
last_name,
birth_date,
gender,
health_plan,
id,
code,
date,
amount
FROM table_a
WHERE (id,
code,
date,
health_plan) IN
(SELECT a.id,
a.code,
a.date,
a.health_plan
FROM table_a a
JOIN table_a b
ON b.health_plan = a.health_plan
AND b.id = a.id
AND b.date = a.date
AND b.code = a.code
AND b.amount <> a.amount
AND (a.amount > 0 AND b.amount < 0)))
SELECT *
FROM amt_cur
ORDER BY id, code, date;
但我得到以下输出
111 A123 20170101 10 BH 111 A123 20100101 -10 BH 311 A124 20170712 20 CVA 311 A124 20170712 -20 CVA 311 A124 20170712 20 CVA
有人可以帮助实现结果吗?
如何简单地使用exists
:
select t.*
from t
where exists (select 1 from t t2 where t2.id = t.id and t2.amount < 0) and
exists (select 1 from t t2 where t2.id = t.id and t2.amount > 0) ;
此查询根据您的规则检索数据:
with t as (
select a.* , count(distinct a.amount)over(partition by a.id,a."DATE",a.code,a.health_plan) "count"
, sum (a.amount) over(partition by a.id,a."DATE",a.code,a.health_plan) "sum"
from table_a a
)
select a.id,a.code,a."DATE",a.amount
from t a where "count">1 and "sum"=0
;
目前它什么都不产生,因为你的数据都不符合规则。 前两行有不同的日期,其中三个有sum!= 0,而last没有一对。
