As long as you have a column to match them on, it's as simple as

select a.col1, b,col2, ...
from tablea a
join tableb b on a.col1 = b.col2

So let's say you have a Purchase Order table where there's a PO Header and a PO Item table with multiple line items:

select a.po_no, b.po_item, b.qty, b.item_price
from po_hdr a
join po_item b
on a.po_no = b.po_no

Try the following:
select a.*, b.* from a left join b on a.KeyID = b.KeyID

KeyID is the common identifier that creates the join between the 2 tables.
