Help on a query

[Sudhir]

Hi,
Iam trying to figure out the query to achieve the output depicted below

create table master (
iss_dtl_seq_nbr int
)

create table child1(
iss_dtl_seq_nbr int,
line_no int
)

create table child2(
iss_dtl_seq_nbr int,
line_no int
)

insert into master
select 1

insert into child1
select 1, 1
insert into child1
select 1, 2

insert into child2
select 1, 1

insert into child2
select 1, 2

insert into child2
select 1, 3
SELECT MASTER.ISS_DTL_SEQ_NBR,CHILD1.LINE_NO, CHILD2.LINE_NO
FROM CHILD1, CHILD2, MASTER
WHERE MASTER.ISS_DTL_SEQ_NBR = CHILD1.ISS_DTL_SEQ_NBR
AND MASTER.ISS_DTL_SEQ_NBR = CHILD2.ISS_DTL_SEQ_NBR
AND CHILD1.LINE_NO = CHILD2.LINE_NO
ORDER BY CHILD1.LINE_NO, CHILD2.LINE_NO

Expected Output:

ISS_DTL_SEQ_NBR LINE_NO LINE_NO
--------------- ----------- -----------
1 1 1
1 2 2
1 NULL 3

Can anybody help with the query to achieve this?

Thanks.

Hi Sudhir,

Thanks for providing the statements to recreate your table structure and
data. The following query will produce the expected output:

select coalesce(master.iss_dtl_seq_nbr, child2.iss_dtl_seq_nbr) AS
iss_dtl_seq_nbr,
child1.line_no, child2.line_no
from master
inner join child1
on master.iss_dtl_seq_nbr = child1.iss_dtl_seq_nbr
right outer join child2
on child1.iss_dtl_seq_nbr = child2.iss_dtl_seq_nbr
and child1.line_no = child2.line_no
order by child2.line_no, child1.line_no
Best, Hugo

Try this:

select master.iss_dtl_seq_nbr, child1.line_no, child2.line_no
from child1 full outer join child2 on child1.iss_dtl_seq_nbr =
child2.iss_dtl_seq_nbr and child1.line_no = child2.line_no
join master on master.iss_dtl_seq_nbr =
isnull(child1.iss_dtl_seq_nbr, child2.iss_dtl_seq_nbr)
