有人可以帮我看看这个SQL查询

Question

我正在尝试创建一个临时表SQL,但是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));

这是错误消息:

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 - 在字段类型后面加上"NOT NULL":

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 - 你有关于"DATETIME"的错字
