Question

I need to count the no.of rooms in eachbuilding, each floor and in each zone..(like this in below picture)

I have tried using distinct and group by, but I am not getting required result.

Answer 1

You have not supplied the actual SQL you have trued, but something like this should work (obviously with the correct field / table names)

SELECT BuildingNo, Floor, Zone, COUNT(Rooms) AS NoOfRooms
FROM myTable
GROUP BY BuildingNo, Floor, Zone
ORDER BY BuildingNo, Floor, Zone
