Oracle Inner Table Query - oracle

Question

I am trying to write a query in Oracle to give totals of active legal entities and inactive legal entities.
The query so far I have is:
select le.Name, b.LE_ID, count(*) As TOTAL, dead.LE_ID as DEAD
from BOOK b
left join Legal_Entity le on le.LE_ID = b.LE_ID
left join
(
select count(LE_ID) as LE_ID
from BOOK
where (Name like '%DUMMY%' or name like '%TEST%' or name like '%DEAD%' or name like '%DO NOT%' or status <> 'Active')
) dead on dead.LE_ID = b.LE_ID
where b.LE_ID = 1234
group by le.Name, b.LE_ID, dead.LE_ID
order by b.LE_ID;
The results I am expecting are:
Name EntityID Total Dead
Entity A 1234 500 200
i.e. for Book.LE_ID = 1234 I would like one row in the result set and a column with the Total number i.e. select * from Book where LE_ID = 1234 and a column with the number of dead books i.e. the inner query
But at the moment, my query is returning NULL for the number of dead rows.
The inner query is working without issue, but I'm clearly missing something here.

Answer 1

I am not sure, but shouldn't it be something like this?
select le.Name, b.LE_ID, count(*) As TOTAL, dead.DEAD as DEAD
from BOOK b
left join Legal_Entity le on le.LE_ID = b.LE_ID
left join
(
select LE_ID, count(LE_ID) as DEAD
from BOOK
where (Name like '%DUMMY%' or name like '%TEST%' or name like '%DEAD%' or name like '%DO NOT%' or status <> 'Active')
group by LE_ID
) dead on dead.LE_ID = b.LE_ID
where b.LE_ID = 1234
group by le.Name, b.LE_ID, dead.LE_ID
order by b.LE_ID;

It is a bit hard to figure out exactly what you are trying to do. After all, you are trying to join between a count and an id, something that is not likely to lead to success.
Your example has a name 'Entity A'. By the rules specified in the query for "dead" entities, there should be none. The name doesn't match this rule.
In all likelihood, you want conditional aggregation. Here is a query that I think gets the totals over all entities:
select count(*) As TOTAL,
sum(case when Name like '%DUMMY%' or name like '%TEST%' or name like '%DEAD%' or name like '%DO NOT%' or status <> 'Active'
then 1 else 0
end) as dead
from BOOK b left join
Legal_Entity le
on le.LE_ID = b.LE_ID;
