MYSQL 简单的循环存储过程

BEGIN
    DECLARE i int DEFAULT 1;
    DECLARE j int DEFAULT 1;
    
    WHILE i<15 DO
        WHILE j<5 DO
            INSERT *** VALUES(NULL,\'***\',i,j,0);
            SET j=j+1;
            IF (i=14 AND j=3) THEN
                SET j=5;
            END IF;
        END WHILE;
        SET j=1;
        SET i=i+1;
