Question

i’m a bit stuck and would appreciate the help….. i’m sure i need to use a sub query but when i try i m getting errors saying returning more than one row….

So this is the code

SELECT to_char(p.releasedate, 'YYYY') AS releaseyear , t.genre
, COUNT(*) AS "Number of awards"
FROM dbf11.film p
JOIN dbf11.genre t
ON p.filmID = t.filmID
GROUP BY p.releasedate, t.genre
ORDER BY p.releasedate, t.genre ;

What i’m trying to do is…. for each year display the no. of films for each genre

What i’m currently getting is

2010 Action 1
2010 Comedy 1
2010 Comedy 1
2011 Action 1
2011 Action 1
2011 Action 1

What i want it to display is

2010 Action 1
2010 Comedy 2
2011 Action 3

Answer 1

SELECT to_char(p.releasedate, 'YYYY') AS releaseyear, 
    t.genre.
    COUNT(*) AS "Number of awards"
FROM dbf11.film p
INNER JOIN dbf11.genre t ON p.filmID = t.filmID
GROUP BY to_char(p.releasedate, 'YYYY'), t.genre
HAVING COUNT(*) > 1
ORDER BY to_char(p.releasedate, 'YYYY'), t.genre;
