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;

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

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.

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

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
