sql - 选择满足两个条件的ID

Question

我一直在尝试从事件表中查询(下面我展示了一个具有预期输出的示例)。

这个表有3个以上的事件类型，但我只显示相关的。这些相关的 3 种类型是:“HRa1”(代码 211)、“HRa2”(代码 12712)和“HRy”(代码 220048)。 'HRa'分为'HRa1'和'HRa2'，因为它们因人将它们插入 table 而异，但它们不会同时发生。

我要选择以下内容:

• 如果只出现这 3 种类型中的一种:如果是 'HRa1' 或 'HRa2'，请选择其所有 'HRa1'/'HRa2' 值(列 valuenum)都在 50 到 110 之间的那些；如果它是“HRy”，则选择所有值(列值)都等于“sinus”的那些。请参阅 ID = 1、2、3、4 和 5。可以存在其他类型的事件，这无关紧要，但只会出现上述 3 种事件之一(请参阅 ID = 3)。

• 如果“HRa1”/“HRa2”和“HRy”都出现，则所有“HRa1”/“HRa2”条目中的“HRa1”/“HRa2”(数值)必须介于 50 和 110 之间，和“HRy”(值)条目必须全部等于“正弦”。 ID = 8 显示了不满足此条件的示例。

• 如果这 3 个都没有出现，当然排除。

我怎样才能做到这一点？

drop table testevents cascade;
create table testevents(
hadm_id int not null,
subject_id int not null,
eventtype int not null,
eventlabel char(30) not null,
value char(360) not null,
valuenum int
);

insert into testevents(hadm_id, subject_id, eventtype, eventlabel, value, valuenum)

output:

3            3
4            4
7            7

我正在尝试以下查询，但对于 ID = 8 它失败了:

select subject_id, hadm_id
from testevents
where eventlabel in ('HRa1', 'HRa2', 'HRy') 
group by subject_id, hadm_id
having ((min(valuenum) >= 50 and max(valuenum) <= 110) or
       (min(value) = 'sinus' and max(value) = 'sinus'))
order by subject_id;

有人可以帮助我吗？ 非常感谢!

Answer 1

你的条件有点复杂。我认为这捕获了逻辑:

select subject_id, hadm_id
from testevents
where eventlabel in ('HRa1', 'HRa2', 'HRy') 
group by subject_id, hadm_id
having (min(eventlabel) = max(eventlabel) and
        min(eventlabel) in ('HRa1', 'HRa2') and
        min(valuenum) >= 50 and
        max(valuenum) <= 110
       ) or
       (min(eventlabel) = max(eventlabel) and
        min(eventlabel) in ('HRy') and
        min(value) = 'sinus' and
        max(value) = 'sinus'
       ) or
       (sum( (eventlabel in ('HRa1', 'HRa2'))::int) > 0 and
        sum( (eventlabel in ('HRy'))::int) > 0 and
        min(case when eventlabel in ('HRa1', 'HRa2') then valuenum end) >= 50 and
        max(case when eventlabel in ('HRa1', 'HRa2') then valuenum end) <= 110 and
        sum( (eventlabel in ('HRy') and value <> 'sinus')::int ) = 0
       )
