SQL—复制表结构及其数据

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
