sql复制表结构和复制整个表数据
阅读:539 输入:2019-01-09 20:10:18

1. 复制表结构及其数据

create table table_name_new as select * from table_name_old

2. 只复制表结构

create table table_name_new as select * from table_name_old where 1=2;

或者:

create table table_name_new like table_name_old

3. 只复制表数据

如果两个表结构一样:

insert into table_name_new select * from table_name_old

如果两个表结构不一样:

insert into table_name_new(column1,column2...) select column1,column2... from table_name_old

SELECT INTO也有这样的功能;

比如,SELECT * INTO table_new FROM table_old

SELECT * INTO table_new FROM table_old WHERE 1=2
