inserting parameters from select into procedure - oracle

Question

I've got this select :
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')
which returns :
NAME - VALUE
MAX_WIN - 100
MAX_BET - 50
MIN_BET - 10
And i've got procedure :
get_percentage (i_player_id, o_session_id, royal_tri_win, o_percentage,
o_min_bet,
o_max_bet,
o_max_win,
o_pot
);
Now I need to insert values from select max_win,max_bet and min_bet into procedures parameters o_max_win,o_max_bet and o_bet_bet..
How can I do that ?
PS. this is procedure where is this code from above. and where are defined all parameters that is used in it..
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;
p_active_session NUMBER;
p_parent number;
v_max_win number;
v_min_bet number;
v_max_bet number;
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
);

Answer 1

Use MAX(CASE WHEN) and store each value in 3 variables.
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;

Alternatively if you want to avoid local variables, you may use implicit cursor loop.
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;
