Question

我有这个选择：

 SELECT  gp.name, gda.value
          FROM   game_definition_aff gda,
         GAME_PARAMETAR gp,
         game_aff ga,
         game_name gn    
         WHERE   4355 = ga.aff_id 
          AND   ga.id = gda.game_aff_id
          AND   gp.id = gda.game_parametar_id
          AND   15 = ga.game_name_id
          AND   gn.game_name_id = ga.game_name_id
          and gp.name in ( 'MIN_BET','MAX_BET','MAX_WIN')

返回：

NAME       -      VALUE

MAX_WIN    -      100

MAX_BET    -       50

MIN_BET    -       10

我有程序：

get_percentage (i_player_id, o_session_id, royal_tri_win, o_percentage,
                             o_min_bet,
                             o_max_bet,
                             o_max_win,
                             o_pot
                            );

现在，我需要将select max_win，max_bet和min_bet中的值插入过程参数o_max_win，o_max_bet和o_bet_bet。.

我该怎么做？

PS。这是上面代码所在的过程。以及在其中定义的所有参数。

   PROCEDURE open_session_3w (
      i_player_id              NUMBER,
      old_session_id           NUMBER,
      i_ip_address             VARCHAR2,
      i_machine_number         VARCHAR2,
      o_last_bet         OUT   NUMBER,
      o_min_bet          OUT   NUMBER,
      o_max_bet          OUT   NUMBER,
      o_max_win          OUT   NUMBER,
      o_credits          OUT   NUMBER,
      o_session_id       OUT   NUMBER,
      o_state            OUT   VARCHAR2
   )
   IS
      o_percentage       NUMBER;
      o_pot              NUMBER;                    
      pom                weak_cur;

   BEGIN
     select parent_id into p_parent from casino_users where party_id = i_player_id;
      check_pl_sess_3w (i_player_id, old_session_id);
      o_session_id :=

     player.open_new_session (i_player_id, i_ip_address,i_machine_number,'GAME SESSION');

 select MAX( CASE WHEN gp.name = 'MAX_WIN' THEN VALUE END ),
           MAX( CASE WHEN gp.name = 'MAX_BET' THEN VALUE END ),
           MAX( CASE WHEN gp.name = 'MIN_BET' THEN VALUE END )
    INTO v_max_win,v_max_bet,v_min_bet
          FROM   game_definition_aff gda,
         GAME_PARAMETAR gp,
         game_aff ga,
         game_name gn    
         WHERE   i_player_id = ga.aff_id 
          AND   ga.id = gda.game_aff_id
          AND   gp.id = gda.game_parametar_id
          AND   15 = ga.game_name_id
          AND   gn.game_name_id = ga.game_name_id
          and gp.name in ( 'MIN_BET','MAX_BET','MAX_WIN') ;

      player.get_percentage (i_player_id,
                             o_session_id,
                             royal_tri_win,
                             o_percentage,
                             COALESCE(v_min_bet,o_min_bet),
                             COALESCE(v_max_bet,o_max_bet),
                             COALESCE(v_max_win,o_max_win),
                             o_pot
                            );

使用MAX（CASE WHEN），并将每个值存储在3个变量中。

DECLARE
v_max_win NUMBER;
v_max_bet NUMBER;
v_min_bet NUMBER;
BEGIN

    select MAX( CASE WHEN gp.name = 'MAX_WIN' THEN VALUE END ),
           MAX( CASE WHEN gp.name = 'MAX_BET' THEN VALUE END ),
           MAX( CASE WHEN gp.name = 'MIN_BET' THEN VALUE END )
    INTO v_max_win,v_max_bet,v_min_bet
    FROM
    game_definition_aff gda,
             GAME_PARAMETAR gp,
             game_aff ga,
             game_name gn    
    ..

..

get_percentage (i_player_id, o_session_id, royal_tri_win, o_percentage,
                             COALESCE( v_min_bet,o_min_bet),
                             COALESCE( v_max_bet,o_min_bet),
                             COALESCE( v_min_win,o_max_win),
                             o_pot
                            );

END;
/

或者，如果要避免使用局部变量，则可以使用隐式游标循环。

for rec in ( --select query above )
LOOP
   get_percentage (i_player_id, o_session_id, royal_tri_win, o_percentage,
                             COALESCE( rec.min_bet,o_min_bet),
                             COALESCE( rec.max_bet,o_min_bet),
                             COALESCE( rec.min_win,o_max_win),
                             pot
                            );
END LOOP;
