Question

I have 3 tables

Division 

id    name  
1       A 
2       B


Region

Id       name     Divsion_id
01      Rim          A


Territory

Id       name       region_id

001      a               01
002      b               01
003      c               01

Now I want to write a query such way that user will select division and its respective territories should get displayed.

How can I write this query, as

there is no direct relation between Divsion and Region?

Answer 1

select t.* from territory t
inner join region r on r.id = t.region_id
inner join devision d on d.name = r.division_id
where d.name = 'A'
