동일한 키를 사용하여 여러 개의 테이블을 하나의 기본 테이블에 결합하십시오.

Question

현재 Oracle에서 방대한 재무 보고서에 대한 SQL 쿼리를 작성하고 있습니다. 이 정보는 질문에는 필요하지 않지만 배경 지식을 제공 할 수 있습니다. 본질적으로 특정 기간의 모든 gl_JE를 가져 와서 실제 트랜잭션으로 분할합니다.

그래서 6 개의 서브 테이블과 기본 테이블을 생성했습니다.

는

기본 테이블은 PK 및 일부 일반 정보 HEADER_ID 및 LINE_NUM

각 서브 레코드 이러한 두 키와 부가 정보를 포함를 생성하는 두 개의 키를 포함한다. 기본 테이블과 서브 테이블 간에는 일대일 관계가있을 수 있습니다. 그리고 기반의 PK가 여러 서브 테이블에있을 수 있습니다.

하위 테이블의 정보를 추가하고 기본 정보를 그대로 유지하면서이 6 개의 테이블을 함께 결합하고자합니다. 유니온 ALL로이 작업을 수행 할 수 있지만 모든 서브 테이블에 동일한 필드를 넣어야한다는 것을 의미하므로이 필드가 최적이 아닙니다.

여기서 말하는 모든 것이 의미가없는 경우의 데이터 예입니다. 서브 테이블을 3 개만 가지고 간단하게 할 것입니다 :

create table base (Header_id int, 
       line_num int, 
       period_num int); 
create table subtable1 (header_id int, 
         line_num int, 
         cost int, 
         description varchar(50)); 
create table subtable2 (header_id int, 
         line_num int, 
         invoice_num int, 
         description varchar(50)); 
create table subtable3 (header_id int, 
         line_num int, 
         value int, 
         description varchar(50)); 

Insert into base values 
    (1, 1 , 4), 
    (1,2,4), 
    (2,5,4), 
    (2,4,4), 
    (3,1,4), 
    (4,2,5); 

Insert into subtable1 values 
    (1, 1, 50, 'Boat'), 
    (1, 1, 30, 'lifejacket'), 
    (2, 4, 4000, 'lifeinsurance'); 
Insert into subtable2 values 
    (1, 1, 89756, 'Boat supplies') 
    (2,5, 5464, 'fake invoice'); 
Insert into subtable3 values 
    (1, 2, 100, 'im running out') 
    (3, 1, 25, 'of ideas'); 

나는 이것을 반환하고 싶습니다. nulls/field 이름을 제발 무시하십시오.

1. 1,1,4,50,'BOAT' 
2. 1,1,4,30,'lifejacket' 
3. 1,1,4,89756, 'boat supplies' 
4. 1,2,4,100,'im running out' 
5. 2,5,4,5464,'fake invoice' 
6. 2,4,4,4000,'lifeinsurance' 
7. 3,1,4,25,'of ideas' 
8. 4,2,5 

아이디어가 있으십니까?

그냥 UNION ALL 사용 -이 라인을 따라 뭔가 : 지금의 약자로 여기 내 실제 쿼리는 같은

SELECT DISTINCT * FROM 
(
     SELECT 
      base.header_id 
      , base.line_num 
      , base.period_num 
      , subtable1.cost col3 
      , subtable1.description col4 
     FROM 
      base 
      left join subtable1 
      on base.header_id = subtable1.header_id and base.line_num = subtable1.line_num 

    UNION ALL 

     SELECT 
      base.header_id 
      , base.line_num 
      , base.period_num 
      , subtable2.invoice_num 
      , subtable2.description 
     FROM 
      base 
      left join subtable2 
      on base.header_id = subtable2.header_id and base.line_num = subtable2.line_num 

    UNION ALL 

     ... 
) 

난 그냥,이 자유를 썼다하지만 뭔가를 트릭을해야합니다, 나는 믿습니다.
