I have two tables lets assume history and Favorites
Favorites
schema is (id int primary key, isFav int) History
schema is (id int) Favorites
table has => songs with id and an int (0 or 1) and history table has => series of id which may be duplicates
I want a SQL statement for selecting ids from favorites which has value = 1 and order by number of occurrence(count) in history table (it may contain or not record with that id)
This should work for you:
SELECT
x.id
, (
SELECT
COUNT(y.id)
FROM y
WHERE y.id = x.id
) as YCount
FROM x
WHERE value = 1
ORDER BY YCount;
