Question

I have the following tables:

TableA (id, tableB_id, tableC_id)
TableB (id, expirationDate)
TableC (id, expirationDate)

I want to retrieve all the results from TableA ordered by tableB.expirationDate and tableC.expirationDate. How can I do this?

Answer 1

select ta.*
from TableA ta
inner join TableB tb on ta.tableB_id = tb.id
inner join TableC tc on ta.tableC_id = tc.id
order by tb.expirationDate, tc.expirationDate

Update:

If you are not getting all the records, then you’ll need to use a left outer join:

select ta.*
from TableA ta
left outer join TableB tb on ta.tableB_id = tb.id
left outer join TableC tc on ta.tableC_id = tc.id
order by tb.expirationDate, tc.expirationDate
