Joining a dual query to another query

Question

dear all;
I am using the following syntax to get a particular user_place from a table which is joined to dual...see syntax below
select distinct ch.user_place from table_one inner join dual on
ch.user_place = 'TEXAS';
which give me the following results below
User_place
TEXAS
now I would like to join this result to another query that gives me the following results below.
syntax for query 2 is
select t2.population_id, t2.male, t2.female from table_zone;
results from query 2
Population Male Female
1000 60% 40%
so that my final result will be
user_place Population Male Female
TEXAS 1000 60% 40%
Hence, can this be done. if so, how can iI do it. Thank you.

select distinct
     ch.user_place
from      table_one
where     ch.user_place     = 'TEXAS'

select distinct
     ch.user_place
,     t2.population_id, t2.male, t2.female
from           table_one
cross join     table_zone
where     ch.user_place     = 'TEXAS'
;This will get the specific results you want in this specific case.
It may get the results you want in general, too, but I can't say for sure because I don't know what the general problem is. If you'd like help, describe what you're trying to do.
