如何將不同表格中的列加載到光標並顯示它們？

Question

我想顯示GAMETABLE中的所有行，並在HOWTOPLAY中顯示其中一行。我搜索了一遍，但無法弄清楚如何從2個表中加載列到一個光標並顯示它們。

使用oracle 11g。

這是我的存儲過程的代碼：

PROCEDURE GetLotteryGame (lg_id IN number, lg_ref OUT lotg_ref_cursor) IS 
    BEGIN 
    OPEN lg_ref FOR 
    SELECT a.GAMEDETAILSID,a.GAMENAME,a.GAMECOST,a.GAMEDESCRIPTION,a.WHERETOPLAY,b.HOWTOPLAYINFO 
     FROM GAMEDETAILS a 
     INNER JOIN HOWTOPLAY b 
      on b.GAMEDETAILSID = a.GAMEDETAILSID 
    WHERE a.GAMEDETAILSID >= lg_id; 
END GetLotteryGame; 

這是我的電話程序的代碼：

SET SERVEROUTPUT ON size 100000 

DECLARE 
v_cursor    LOTTERYGAMEPKG.lotg_ref_cursor; 
v_gamedetailsid  GAMEDETAILS.gamedetailsID%type; 
v_gamename   GAMEDETAILS.gamename%type; 
v_gamecost   GAMEDETAILS.gamecost%type; 
v_gamedescription GAMEDETAILS.gamedescription%type; 
v_wheretoplay  GAMEDETAILS.wheretoplay%type; 
v_howtoplayinfo  HOWTOPLAY.howtoplayinfo%type; 
BEGIN 
LOTTERYGAMEPKG.GetLotteryGame(lg_id => 1, 
          lg_ref => v_cursor); 

LOOP 
    FETCH v_cursor 
    INTO v_gamedetailsID, v_gamename, v_gamecost, v_gamedescription, v_wheretoplay,   v_howtoplayinfo; 
EXIT WHEN v_cursor%NOTFOUND; 
DBMS_OUTPUT.PUT_LINE(v_gamedetailsID || ',' || v_gamename || ',' || v_gamecost || ',' || v_gamedescription || ',' || v_wheretoplay || ',' v_howtoplayinfo); 
END LOOP; 
CLOSE v_cursor; 
END;

你忘',' v_howtoplayinfo)之間的毗連運算。

應該是',' || v_howtoplayinfo)。

順便說一句，你可以打破這麼長的路線。如果你這樣做，你可以閱讀它們而不必滾動到右側，而且你更有可能自己發現這樣的錯誤。
