Can I create a new table using strcuture of another existing table ????

Question

hello all -
If I need to create table as the duplicate table for another table. I donot need data from that table, as I am going to populate date later on.
So all need is the structure, constraints of the table to create a new table.
create table new_temp as
select * from old_temp;
above command creates a table with the data, what if I donot want the data, only the defination.
Any help woud really appreciated.
Thanks
Rama

Answer 1

but create table as select..
CAN'T create constraint on new table it copy only data
not constraint
so create new table with structure as well as
constraint use
SELECT dbms_metadata.get_ddl('TABLE','EMP') FROM DUAL;
only in 9i
