1.复制表结构及数据到新表
复制代码 代码如下:
CREATE TABLE 新表
SELECT * FROM 旧表
2.只复制表结构到新表
复制代码 代码如下:
CREATE TABLE 新表
SELECT * FROM 旧表 WHERE 1=2
即:让WHERE条件不成立.
方法二:(低版本的mysql不支持,mysql4.0.25 不支持,mysql5已经支持了)
复制代码 代码如下:
CREATE TABLE 新表
LIKE 旧表
3.复制旧表的数据到新表(假设两个表结构一样)
复制代码 代码如下:
INSERT INTO 新表
SELECT * FROM 旧表
4.复制旧表的数据到新表(假设两个表结构不一样)
复制代码 代码如下:
INSERT INTO 新表(字段1,字段2,…….)
SELECT 字段1,字段2,…… FROM 旧表
