ストアドプロシージャの

Question

私は手順

事業（abnnumber、名）

business_industry（abnnumber、industryid）

産業（industryid、unionid）

trade_unionで使用される4つのテーブルを持っています

私は、労働組合のタイトルを1行で取得し、すべてのビジネスABNNUMBERとビジネス名を異なる行に割り当てました。ストアドプロシージャ。私が試したどの

である：

CREATE [OR REPLACE] PROCEDURE INDUSTRY_INFORMATION 
[enter image description here][1](P_INDUSTRYID in integer, 
P_UNIONTITLE OUT VARCHAR2, 
P_BUSINESSNAME OUT VARCHAR2) AS 
BEGIN 
SELECT TRADE_UNION.UNIONTITLE, BUSINESS.BUSINESSNAME INTO    
P_UNIONTITLE,P_BUSINESSNAME 
FROM BUSINESS inner join BUSINESS_INDUSTRY ON 
BUSINESS.ABNNUMBER=BUSINESS_INDUSTRY.ABNNUMBER 
INNER JOIN INDUSTRY ON BUSINESS_INDUSTRY.INDUSTRYID=INDUSTRY.INDUSTRYID 
INNER JOIN TRADE_UNION ON INDUSTRY.UNIONID=TRADE_UNION.UNIONID; 
END; 

Sample data is in the link http://www.mediafire.com/file/8c4dwn4n88n8a42/strd_procedure.txt 

必要な出力は、 ``

ABNNUMBERビジネス名（次の行）

UNIONTITLE（1行）であるべきである[1]： https://i.stack.imgur.com/sGuwe.jpg

Answer 1

私はこのようなものが必要だと思う：

create or replace procedure industry_info is 
begin 
    for r in (
    select tu.uniontitle ut, 
      listagg('['||b.abnnumber||'] '||b.businessname, ', ') 
      within group (order by b.businessname) blist 
     from business b 
     join business_industry bi on b.abnnumber = bi.abnnumber 
     join industry i on bi.industryid = i.industryid 
     join trade_union tu on i.unionid = tu.unionid 
     group by tu.uniontitle) 
    loop 
    dbms_output.put_line(r.ut); 
    dbms_output.put_line(r.blist); 
    dbms_output.put_line('-----'); 
    end loop; 
end; 

機能listaggは、Oracle 11g以降で使用できます。
