Question

This query:

select *
from table_a
, table_b
where table_a.id = table_b.id(+)
   and table_b.name = 'BENEFICIARY'

returns me no records. table_b has no records with name=’BENEFICIARY’. But the outer join should return all records from table_a regardless . No?
The below query returns records from table_a as expected:

select *
from table_a
, (select *
   from table_b
   where table_b.name = 'BENEFICIARY') AS table_b1
where table_a.id = table_b1.id(+)

Why is the first query not returning records?

Answer 1

In the first query, the filter is being applied to the results, after the join.

Try

select * 
from table_a
     left join table_b 
     on table_a.id=table_b.id
     and table_b.name='BENEFICIARY'
