`table_title` VARCHAR(100) NOT NULL,
`table_author` VARCHAR(40) NOT NULL,
`created_date` DATE,
PRIMARY KEY ( `table_id` )
)ENGINE=InnoDB DEFAULT CHARSET=utf8;

INSERT INTO table_name ( field1, field2,...fieldN ) VALUES ( value1, value2,...valueN );
# 如果数据是字符型,必须使用单引号或者双引号,如:"value"
INSERT INTO demo_table
(table_title, table_author, created_date)
VALUES
("MySQL Tutorials", "xgqfrms", NOW());
# SELECT 语句查询数据表中数据的通用语法
SELECT column_name,column_name
FROM table_name
[WHERE Clause]
[LIMIT N][ OFFSET M];
# UPDATE 语句修改数据表中数据的通用语法
UPDATE table_name SET field1=new-value1, field2=new-value2
