MySQL存儲過程給運行時錯誤

Question

我已經在MySQL中創建一個存儲過程，如：

delimiter $$ 
drop procedure if exists test9$$ 
Create procedure test9(test_type varchar(20)) 
Reads sql data 
begin 

    Declare 1_id int; 
    Declare 1_date varchar(20); 
    Declare done int default 0; 
    Declare cur1 cursor for 
     select id,name from buyers where ticket_type='test_type'; 
    Declare Continue handler for not found set done=1; 

    Create temporary table if not exists ticketninja.history2(n_id int,n_date varchar(20)); 

    Open cur1; 
     hist_loop:loop 
      fetch cur1 into 1_id,1_date; 

       if done=1 then 
        leave hist_loop; 
       end if; 

     insert into ticketninja.history2(n_id ,n_date) values(1_id,1_date); 
     End loop hist_loop; 
    close cur1; 

    select * from history2; 
    drop table history2; 

End; 

$$ 

delimiter ; 

，但是當我把它用，

call test9('platinum'); 

它返回一個錯誤說：

#1312 - PROCEDURE ticketninja.test1 can't return 
a result set in the given context 

我在做什麼錯在這裏？

我想你需要一個OUT變量（參見第一個代碼示例here）
