I have table emp
and I want to create a duplicate table from the emp
table. I tried the below query, which is copying all the table columns, data and the not null constraints.
create table emp_backup as select * from emp.
Is there any way to duplicate a table along with all constraints?
Here is the base table:
create table emp
(
empno number Primary key,
ename varchar2(50),
deptno number,
constraint emp_deptno_fk foreign key(deptno) references dept(deptno)
)
I need to create a table emp_backup from the emp along with emp_deptno_fk constraint.

You may try to obtain the source table's DDL using:
Select it into a variable, replace table name to one you need (maybe edit or remove something else) and execute.
