mysql創建表並獲取錯誤1064

Question

CREATE TABLE course000 (
id_number int(9) unsigned zerofill NOT NULL default '000000000', 
grade_1 int(3) default NULL, 
grade_2 int(3) default NULL, 
grade_final int(3) default NULL, 
PRIMARY KEY (id_number) 
); 

請幫助我;爲什麼我不能使用這段代碼來構建mysql表？

Answer 1

grade_1 int(3) default NULL//you have missing ,(comma here) 

Answer 2

只是把,後grade_1 INT（3）默認爲NULL

CREATE TABLE course000 (
id_number int(9) unsigned zerofill NOT NULL default '000000000', 
grade_1 int(3) default NULL, 
grade_2 int(3) default NULL, 
grade_final int(3) default NULL, 
PRIMARY KEY (id_number) 
);
