what command is used to create a table by copying the structure of another table including constra..

Answer / a.jyothsna

I know copying the structure of one table but not the
constraints also:
create table newtablename as
select * from oldtablename;

with the above query total data will also be copied.
But to copy only the structure.

create table newtablename as
select * from oldtablename
where 1=2;

Answer / saurabh agrawal

We can only copy the structure of the table and not the
constraints.
Syntax is as below:
Create table newtablename as select * from oldtablename;

In this way only NOT NULL constraint specified on any
column of the OLDTABLE will automatically get copied into
the NEWTABLE but other constraint will have to be created
manually.

Answer / ben

crete view (view_name) as
select * from (table);

In SQL, a view is a virtual table based on the result-set of an SQL statement.

A view contains rows and columns, just like a real table. The fields in a view are fields from one or more real tables in the database.

i think this is the right answer
