存儲過程

我有4個表中的過程存儲過程

業務（abnnumber，名）

business_industry（abnnumber，industryid）

業（industryid，蚌）

trade_union使用（unionid）

我被分配到一行中獲得工會職稱，所有企業ABNNUMBER和企業名稱分別在不同行中使用存儲過程。

我嘗試什麼是：

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

需要的輸出應是

UNIONTITLE（一行）

ABNNUMBER BUSINESS NAME（下一行）

你需要的數據表或查詢？ –

程序代碼是**高度特定於供應商的** - 所以請添加一個標籤以指定您是使用mysql，postgresql，sql-server，oracle還是db2還是別的什麼完全。 –

我提供了數據和輸出格式。 –

我懷疑你需要這樣的東西：

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;

功能listagg是在Oracle 11g或更高版本中可用。
