Oracle same user same library copy table structure ____oracle

First, copy the syntax of the table:
Create table table name as (subquery)

Example: Copy oracel the table EMP in the default database Scott after installation

CREATE TABLE Myemp as (SELECT * from EMP);

This example represents the table structure and the contents of the table copied over together.

II. Replication Table Structure

The CREATE table name as (subquery where 1=2), which adds a condition that is never possible (1=2) on the basis of the above, represents a copy-only table structure, but does not copy the contents of the table.

Example: Create TABLE MYEMP2 as (SELECT * from EMP where 1=2);
