Question

I have two SQL queries for counting the rows from the table tContentNode, depending on the type 2 or 3.
Query 1:

SELECT count(*) _countA FROM TCONTENTNODE WHERE type = '2' 
     AND parentid ='02b3abc2-4983-485a-ab09-1a8cb328b9b5';

Query 2:

SELECT count(*) _countB FROM TCONTENTNODE WHERE type = '3' 
     AND parentid ='02b3abc2-4983-485a-ab09-1a8cb328b9b5';

Now I want to get the values of _countA and _countB using only one query. How can I get the counts using one query. Is there any way to do that. I am using SQLite Database.

EDIT:
I want values of _countA and _countB separately, not both together(Not using IN).

Answer 1

Try to use group by

SELECT type,count(*) as cnt
FROM TCONTENTNODE 
WHERE parentid ='02b3abc2-4983-485a-ab09-1a8cb328b9b5';
group by type

for two variables:

SELECT 
  COUNT(case TCONTENTNODE.type when '2' then 1 end) as _countA,
  COUNT(case TCONTENTNODE.type when '3' then 1 end) as _countB
FROM  TCONTENTNODE 
WHERE TCONTENTNODE.parentid ='02b3abc2-4983-485a-ab09-1a8cb328b9b5';
