我想在程序的开头使用两个游标
这些是table
人。

DECLARE R CURSOR FOR SELECT C.CODE FROM people;  
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done2 = TRUE;
DECLARE classes CURSOR FOR    SELECT DISTINCT a.CODE FROM classes;  
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done1 = TRUE;

给两个循环，一个在另一个里面。。。。。。。。
但我要找回这个信息：
处理程序声明之后的游标声明。。。。。。。。。。。。。

DECLARE v_cdclass INT;
DELCARE v_codperson INT;
DROP TABLE IF EXISTS temp1;
CREATE TEMPORARY TABLE temp1 
(
  id  INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,  
  cdfunc         INT(11),
  class           INT
); 
OPEN R; 
    loop0: LOOP
         FETCH R INTO v_codperson; 
            IF done2 THEN
               LEAVE loop0;
            END IF;

            BLOCO2: BEGIN

              OPEN classes;      
                 loop1: LOOP    
                    FETCH classes INTO v_cdclass ;  
                    IF done1 THEN
                        LEAVE loop1;
                    END IF;
                        INSERT INTO temp1 
                        ( cdfunc,  class )
                        VALUES 
                        ( v_codperson , v_cdclass);  
                  END LOOP loop1;   
                CLOSE classes;        

            END BLOCO2;
    END LOOP ;      
CLOSE R; 
SELECT * FROM temp1;
