insert into where not exists in hive

Question

I need the hive syntax for this equivalent in ansi sql

insert into tablea
(id)
select id 
from tableb
where id not in (select id from tablea)

Answer 1

Use left outer join with a filter that the tableA.id is null:

insert overwrite into tableA (id)
select b.id from tableB b left outer join tableA a
 on a.id = b.id
where a.id is null
