   `table_title` VARCHAR(100) NOT NULL,
   `table_author` VARCHAR(40) NOT NULL,

# CREATE TABLE table_name (column_name column_type, ..., column_name column_type, );

   `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 语句插入数据表中数据的通用语法

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
