oracle如何在oracle中复制表结构和表数据
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
