Question

我有一个SQL查询，我希望看到没有与任何行关联的服务类型的声明。我的下面的查询返回符合条件的一行。但是，还有另一条带有服务类型的行，这意味着我不想看到这一点。因为我的查询中的组是看到行并返回它然后分别查看第二行并将其删除

select distinct a.claim_id,
       count(a.receipt_id) as Count_Receipts, 
       sum(a.billed_amount) as Total_Billed_Amount,
       (case 
         when a.service_type_id is null then 
             count(a.receipt_id) 
         else 0 
       end) test
from cd_roc_claim_item a, 
     cd_hospital b , 
     cd_Claim_header c
where a.hospital_id = b.hospital_id
and a.claim_id=c.claim_id (+)
and b.hos_cat_id='PUBL'
and c.claim_status is null
and a.claim_id='123456'
group by a.claim_id, 
         a.service_type_id 
having count(a.receipt_id) =1
       and sum(a.billed_amount) in 
         ('80','160','240','320','400','480','560','640','720','800')
;

Answer 1

如果您只想报告任何声明项目中service_type没有值的声明：

select ci.claim_id
     , count(ci.receipt_id) as count_receipts
     , sum(ci.billed_amount) as total_billed_amount
     , count(*) as claim_items
from   cd_roc_claim_item ci
       left join cd_hospital ho
            on  ho.hospital_id = ci.hospital_id
       left join cd_claim_header cl
            on  cl.claim_id = ci.claim_id
where  cl.claim_status is null
group by ci.claim_id
    -- , ci.service_type_id  -- Edit (following comments): this was part of the problem
having count(ci.service_type_id) = 0
and sum(ci.billed_amount) in (80, 160, 240, 320, 400, 480, 560, 640, 720, 800);

CLAIM_ID   COUNT_RECEIPTS TOTAL_BILLED_AMOUNT CLAIM_ITEMS
---------- -------------- ------------------- -----------
1                       2                 160           2

问题是医院类别，因为每个索赔项目可能适用于具有不同类别的不同医院。您是否只想查看所有项目是针对医院类别PUBL，还是至少有一个或哪些内容的声明？

测试设置：

create table cd_hospital
( hospital_id integer primary key
, hos_cat_id varchar2(10) );

create table cd_claim_header
( claim_id varchar2(10) primary key
, claim_status varchar2(10) );

create table cd_roc_claim_item
( claim_item_id integer generated always as identity primary key
, claim_id references cd_claim_header not null
, hospital_id references cd_hospital not null
, billed_amount number not null
, service_type_id integer
, receipt_id integer );

insert into cd_hospital (hospital_id, hos_cat_id) values (1, 'PUBL');
insert into cd_hospital (hospital_id, hos_cat_id) values (2, 'PRIV');

insert into cd_claim_header(claim_id, claim_status) values (1, null);
insert into cd_claim_header(claim_id, claim_status) values (2, 'CLOSED');

insert into cd_roc_claim_item (claim_id, hospital_id, billed_amount, service_type_id, receipt_id)
select ch.claim_id, ho.hospital_id, 80, null, 1
from   cd_claim_header ch
       cross join cd_hospital ho
where  ch.claim_id = 1
union all
select ch.claim_id, ho.hospital_id, 640, 123, 1
from   cd_claim_header ch
       cross join cd_hospital ho
where  ch.claim_id = 2;

根据评论进行修改：

要包含声明包含和不包含服务类型的项目的情况，我们会更新一行：

update cd_roc_claim_item set service_type_id = null
where  claim_id = 2 and hospital_id = 1;

现在测试数据如下所示：

select ci.claim_id, ch.claim_status, ci.hospital_id, ho.hos_cat_id, ci.service_type_id, ci.receipt_id
from   cd_roc_claim_item ci
       join cd_claim_header ch
            on  ch.claim_id = ci.claim_id
       join cd_hospital ho
            on  ho.hospital_id = ci.hospital_id
order by ch.claim_id;

CLAIM_ID   CLAIM_STATUS  HOSPITAL_ID HOS_CAT_ID  SERVICE_TYPE_ID  RECEIPT_ID
---------- ------------ ------------ ---------- ---------------- -----------
1                                  2 PRIV                                  1
1                                  1 PUBL                                  1
2          CLOSED                  2 PRIV                    123           1
2          CLOSED                  1 PUBL                                  1

据我了解，您希望报告声明1（汇总到一行），因为它的所有项都没有服务类型。不应显示索赔2，因为其中一个项目具有服务类型。
