MySQL創建存儲過程失敗，但所有內部查詢單獨成功？

Question

我剛剛在MySQL中創建了一個簡單的數據庫，並且正在學習如何編寫存儲過程。我熟悉M $ SQL而據我可以看到下面應該工作：

use mydb; 
-- -------------------------------------------------------------------------------- 
-- Routine DDL 
-- -------------------------------------------------------------------------------- 
DELIMITER // 
CREATE PROCEDURE mydb.doStats() 
BEGIN 

CREATE TABLE IF NOT EXISTS resultprobability (
ballNumber INT NOT NULL , 
probability FLOAT NULL, 
PRIMARY KEY (ballNumber)); 

CREATE TABLE IF NOT EXISTS drawProbability (
drawDate DATE NOT NULL , 
ball1 INT NULL , 
ball2 INT NULL , 
ball3 INT NULL , 
ball4 INT NULL , 
ball5 INT NULL , 
ball6 INT NULL , 
ball7 INT NULL , 
score FLOAT NULL , 
PRIMARY KEY (drawDate)); 

TRUNCATE TABLE resultprobability; 

TRUNCATE TABLE drawprobability; 

INSERT INTO resultprobability (ballNumber, probability) 
(select resultset.ballNumber ballNumber,(count(0)/(select count(0) from resultset)) probability 
    from resultset 
    group by resultset.ballNumber); 

INSERT INTO drawProbability (drawDate, ball1, ball2, ball3, ball4, ball5, ball6, ball7, score) 
(select distinct r.drawDate, a.ballnumber ball1, b.ballnumber ball2, 
c.ballnumber ball3, d.ballnumber ball4, e.ballnumber ball5, 
f.ballnumber ball6,g.ballnumber ball7, 
((a.probability + b.probability + c.probability + d.probability + e.probability + f.probability + g.probability)/7) score 
from resultset r 
inner join (select r.drawDate, r.ballNumber, p.probability from resultset r inner join resultprobability p on p.ballNumber = r.ballNumber where r.appearence = 1) a on a.drawdate = r.drawDate 
inner join (select r.drawDate, r.ballNumber, p.probability from resultset r inner join resultprobability p on p.ballNumber = r.ballNumber where r.appearence = 2) b on b.drawdate = r.drawDate 
inner join (select r.drawDate, r.ballNumber, p.probability from resultset r inner join resultprobability p on p.ballNumber = r.ballNumber where r.appearence = 3) c on c.drawdate = r.drawDate 
inner join (select r.drawDate, r.ballNumber, p.probability from resultset r inner join resultprobability p on p.ballNumber = r.ballNumber where r.appearence = 4) d on d.drawdate = r.drawDate 
inner join (select r.drawDate, r.ballNumber, p.probability from resultset r inner join resultprobability p on p.ballNumber = r.ballNumber where r.appearence = 5) e on e.drawdate = r.drawDate 
inner join (select r.drawDate, r.ballNumber, p.probability from resultset r inner join resultprobability p on p.ballNumber = r.ballNumber where r.appearence = 6) f on f.drawdate = r.drawDate 
inner join (select r.drawDate, r.ballNumber, p.probability from resultset r inner join resultprobability p on p.ballNumber = r.ballNumber where r.appearence = 7) g on g.drawdate = r.drawDate 
order by score desc); 

END 
// 
DELIMITER ; 

，而不是我得到以下

Executed successfully in 0.002 s, 0 rows affected. 
Line 1, column 1 

Error code 1064, SQL state 42000: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 26 
Line 6, column 1

    from resultset 
    group by resultset.ballNumber); 

INSERT INTO d' at line 1 
Line 31, column 51 

Error code 1064, SQL state 42000: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') score 
from resultset r 
inner join (select r.drawDate, r.ballNumber, p.probabi' at line 1 
Line 39, column 114 

Execution finished after 0.002 s, 3 error(s) occurred. 

我在做什麼錯？我似乎已經耗盡了我有限的心智能力！

以下有關取出插入...選擇映射，然後重新運行建議後，我收到以下錯誤

「的所有內部查詢成功獨自」

不，他們不，這裏的第一個平常supect失敗，則：

INSERT INTO drawProbability (...) (select... 

失去「（」前選擇，重新運行，複試，解決下一個語法錯誤作爲急於解決的辦法是沒有理由跳過基本呃。如果你不這樣做，尤其不要聲稱已經運行它們。
