语法：INSERT INTO table_name1 (column_list) SELECT (column_list2) FROM table_name2 WHERE (condition);
以下创建 person 和 person_old 两个表，将 person_old 的查询结果然后插入到 person 表中
mysql> CREATE TABLE person # 创建 person 表 -> ( -> id INT UNSIGNED NOT NULL AUTO_INCREMENT, -> name CHAR(40) NOT NULL DEFAULT ‘‘, -> age INT NOT NULL DEFAULT 0, -> info CHAR(50) NULL, -> PRIMARY KEY (id) -> );
mysql> CREATE TABLE person_old # 创建 person_old 表 -> ( -> id INT UNSIGNED NOT NULL NULL AUTO_INCREMENT, -> name CHAR(40) NOT NULL DEFAULT ‘‘, -> age INT NOT NULL DEFAULT 0, -> info CHAR(50) NULL, -> PRIMARY KEY (id) -> );
mysql> INSERT INTO person_old VALUES (1, ‘Harry‘, 20, ‘student‘), (2, ‘Beckham‘, 31, ‘police‘); # 在 person_old 表中插入两条数据
mysql> INSERT INTO person(id, name, age, info) SELECT id, name, age, info FROM person_old; # 将 person_old 的查询结果然后插入到 person 表中
mysql> SELECT * FROM person; # 查询 person 表是否有插入数据
