I need to take values from a database and put them into a List<Long>
. I made a native query but it doesn’t work correctly. Here’s a picture of the column on my database:
I need to count the same statuses (“W” and “I” represent the same status but are represented by another letter). I prepared a query as shown below:
@Query(value = "SELECT COUNT(CASE WHEN table.status = 'W' OR table.status = 'I' THEN 1 ELSE 0 END) AS WI," " COUNT(CASE WHEN table.status = 'S' THEN 1 ELSE 0 END) AS S," + " COUNT(CASE WHEN table.status = 'N' THEN 1 ELSE 0 END) AS N," + " COUNT(CASE WHEN table.status = 'D' THEN 1 ELSE 0 END) AS D," + " COUNT(CASE WHEN table.status = 'E' THEN 1 ELSE 0 END) AS E," + " COUNT(CASE WHEN table.status = 'T' THEN 1 ELSE 0 END) AS T" + " FROM table.table table" + " WHERE table.id = :id"+ " GROUP BY table.status" + " ORDER BY table.status ASC", nativeQuery = true) List<Long> query1 (Long id);
But it’s not working correctly. When I run the query I get the following result:
But it should be {2(D),2(E),1(N),1(S),1(T),3(W and I). Do you have any idea on how to fix it?

Answer
This query returns what you want:
select count(*) from ( SELECT CASE WHEN status = 'W' OR status = 'I' THEN 'WI' else status end as status FROM @table ) as a group by status order by status
So maybe this is the code you require (you have very complex table names):
@Query(value = "select count(*) from (" + " SELECT CASE WHEN table.status = 'W' OR table.status = 'I' THEN 'WI' else table.status end as status" + " FROM table.table table " + " WHERE table.id = :id"+ " ) as a " + " group by status" + " order by status", nativeQuery = true) List<Long> query1 (Long id);
