I want to join two tables ,
x
booking table
id from_branch to_branch
1 2 4
2 3 4
Branch Table
id name
1 pune
2 mumbai
3 nanded
4 parbhani
5 aurangabad
As above tables show , I joint them with the id common in both tables ( from_branch , to_branch )
My Query:
SELECT booking.id,
booking.from_branch,
booking.to_branch,
branch.branch_id,
branch.branch_name AS "FROM",
branch.branch_name AS "TO"
FROM booking
JOIN branch
ON booking.from_branch = branch.branch_id
WHERE booking.from_branch = branch.branch_id
OR booking.to_branch = branch.branch_id
how i can get result like
id from_branch to_branch FROM TO
1 2 4 Mumbai Parbhani
2 3 4 Nanded Parbhani

Answer
use join with Branch table twice
select b.from_branch,b.to_branch,
bn.name as from_branch_name,
bn1.name as to_branch_name
from booking b join branch bn
on b.from_branch=bn.id
join branch bn1 on b.to_branch=bn1.id
