php - 错误 #1064 - 您的 SQL 语法有错误

Question

无法弄清楚我的 SQL 语句有什么问题，完整的错误消息是

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'NOT NULL , 
    `Sex` BOOLEAN NOT NULL , 
    PRIMARY KEY(userID)
    )' at line 7

实际代码是

CREATE TABLE `car_rental`.`users` ( 
`userID` int(9) AUTO_INCREMENT NOT NULL ,
`First Name` VARCHAR(25) NOT NULL , 
`Last Name` VARCHAR(55) NOT NULL ,
`E-mail Address` VARCHAR(55) NOT NULL , 
`Age` INT NOT NULL , 
`Password` VARCHAR NOT NULL , 
`Sex` BOOLEAN NOT NULL , 
PRIMARY KEY(userID)
) 
ENGINE = InnoDB;

Answer 1

错误主要是因为:

`Password` VARCHAR NOT NULL

将其更改为:

`Password` VARCHAR(60) NOT NULL

希望这有帮助。
