CREATE TABLE user1(

id INT UNSIGNED AUTO_INCREMENT KEY,

username VARCHAR(20) NOT NULL UNIQUE,

age TINYINT UNSIGNED NOT NULL DEFAULT 18,

sex ENUM('男','女','保密')NOT NULL DEFAULT '保密',

addr VARCHAR(20) NOT NULL DEFAULT '北京',

married TINYINT(1) NOT NULL DEFAULT 0,

salary FLOAT(8,2) NOT NULL DEFAULT 0
