ID GARAGE_NAME
  1    GARAGE_1
  2    GARAGE_2
PERSONS

ID GARAGE_ID NAME
  1         1 NAME1_1
  2         1 NAME1_2
  3         1 NAME1_3

  5         1 NAME1_5
  6         1 NAME1_6
  7         2 NAME2_1

        2    GARAGE_2 CAR2_3 NAME2_3
        2    GARAGE_2 CAR2_4 NAME2_4
        2    GARAGE_2 CAR2_5
        2    GARAGE_2 CAR2_6 How can I achieve this output?
Is it an issue for analytical SQL?
Dear community, I need your help!
Kind regards

Answer 1

Looks like just an outer join..
But how are you jining cars and persons -- based on name?
Or Something like this?
with c as
  select c.garage_id,c.car,g.garage_name g_name,
         row_number() over(partition by c.garage_id order by c.id) rn
  from cars c,garage g
  where c.garage_id = g.id
p as
  select p.garage_id,p.name p_name,g.garage_name g_name,
         row_number() over(partition by p.garage_id order by p.id) rn
  from persons p,garage g
  where p.garage_id = g.id
select nvl(p.garage_id,c.garage_id) garage_id,
       nvl(p.g_name,c.g_name) garage_name,
       car,p_name person
from c
     full outer join p on
      (c.garage_id = p.garage_id and c.rn = p.rn);
GARAGE_ID GARAGE_NAME CAR    PERSON
        1 GARAGE_1    CAR1_1 NAME1_1
        1 GARAGE_1    CAR1_2 NAME1_2
        1 GARAGE_1    CAR1_3 NAME1_3
        1 GARAGE_1    CAR1_4 NAME1_4
        1 GARAGE_1           NAME1_5
        1 GARAGE_1           NAME1_6
        2 GARAGE_2    CAR2_1 NAME2_1
        2 GARAGE_2    CAR2_2 NAME2_2
        2 GARAGE_2    CAR2_3 NAME2_3
        2 GARAGE_2    CAR2_4 NAME2_4
        2 GARAGE_2    CAR2_5        
        2 GARAGE_2    CAR2_6        
12 rows selected If this is not what you want, please explain the logic to reach at your output..
