sql 複製表結構和複製整個表資料
阿新 • • 發佈:2019-01-11
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
