Answer 1

You can use this query:

SELECT a.id,a.code,a.name,
max(case when b.month=1 then 1 else "-" end) as month1,
max(case when b.month=2 then 1 else "-" end) as month2,
max(case when b.month=3 then 1 else "-" end) as month3
FROM `table_a` as a
left join table_b as b on a.name= b.name
group by a.name
