sql 複製表結構和複製整個表資料

1. 複製表結構及其資料:

create table table_name_new as select * from table_name_old

2. 只複製表結構:

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. 只複製表資料:

如果兩個表結構一樣:

insert into table_name_new select * from table_name_old

如果兩個表結構不一樣:

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

SELECT INTO也有這樣的功能;

比如,SELECT * INTO table_new FROM table_old

SELECT * INTO table_new FROM table_old WHERE 1=2
