Question

How to create a table by copying only the columns from multiple tables??

eg. t1 with fields (A1,A2,A3)

t2 with fiedls (D1,D2,D3)

t3 with fields (Z1,Z2,Z3)

Now I’ve to create a new table using only the fields not the values from the above three tables i.e.

new_tbl (A1,A2,A3,D1,D2,D3,Z1,Z2,Z3)

How can I do it??

Answer 1

try this:

create table new_tbl as
select * 
from   t1
join   t1 on 1=2
join   t3 on 1=2

the condition 1=2 is always false.. so it will not return any data but the column header..
