1.复制表结构及数据到新表

CREATE TABLE 新表
SELECT * FROM 旧表

2.仅仅复制表结构到新表

CREATE TABLE 新表
SELECT * FROM 旧表 WHERE 1=2
即:让WHERE条件不成立.
方法二:(低版本号的mysql不支持，mysql4.0.25 不支持，mysql5已经支持了)
CREATE TABLE 新表
LIKE 旧表

3.复制旧表的数据到新表(如果两个表结构一样)

INSERT INTO 新表
SELECT * FROM 旧表

4.复制旧表的数据到新表(如果两个表结构不一样)

INSERT INTO 新表(字段1,字段2,…….)
SELECT 字段1,字段2,…… FROM 旧表
