有人可以帮我看看这个SQL查询

Question

我想在SQL创建一个临时表，但有一个我无法识别的错误。

CREATE TEMPORARY TABLE Guest(ID INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY, 
ticket_id NOT NULL VARCHAR(255), 
event_id NOT NULL INT (11), 
user_id NOT NULL INT (11), 
fullname NOT NULL VARCHAR(255), 
delivery NOT NULL VARCHAR(255), 
ticket_type NOT NULL VARCHAR(255), 
ticket_price NOT NULL DECIMAL(19,4), 
fees NOT NULL DECIMAL(19,4), 
total_price NOT NULL DECIMAL(19,4), 
barcode NOT NULL VARCHAR(255), 
purchase_time NOT NULL datatime, 
person_pickup NOT NULL varchar(80), 
Qty NOT NULL INT(11)); 

以下是错误消息：

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to usenear 'NOT NULL VARCHAR(255),event_id NOT NULL INT (11),user_id NOTNULL INT (11),fulln' at line 1 

Answer 1

1 - 将 “NOT NULL” 字段类型后：

CREATE TEMPORARY TABLE Guest(ID INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY, 
ticket_id VARCHAR(255) NOT NULL, 
event_id INT (11) NOT NULL, 
user_id INT (11) NOT NULL, 
fullname VARCHAR(255) NOT NULL, 
delivery VARCHAR(255) NOT NULL, 
ticket_type VARCHAR(255) NOT NULL, 
ticket_price DECIMAL(19,4) NOT NULL, 
fees DECIMAL(19,4) NOT NULL, 
total_price DECIMAL(19,4) NOT NULL, 
barcode VARCHAR(255) NOT NULL, 
purchase_time datetime NOT NULL, 
person_pickup varchar(80) NOT NULL, 
Qty INT(11) NOT NULL); 

2 - 你的 “DATETIME” 有一个错字
