Answer of the question is wrong !!

select @@VERSION

create table #t1 (col int not null)

create table #t2 (col int not null)

create table #t3 (col int not null)

insert #t1 values (1),...

As far I know, Primary key, constraints & index - all are valid only for temporary table (#Table) where as only first 2 are valid for table variable (@Table).
