나는 다음과 같은 것이 필요하다고 생각합니다. :

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; 

기능 listagg 나중에 오라클 11g 또는 사용할 수 있습니다.
