I have a pretty simple query:
Select title, avg(score) from votes group by title order by avg(score) Desc
This returns a result like this:
Abbey Road 4.0
The White Album 3.5
Meet the Beatles 3.0
The values in the score field are always 1, 2, 3, 4, or 5
What I really need from my query is 5 more columns (1, 2, 3, 4, and 5) with a count of how many votes each of those columns received. So the result set might be like this.
Abbey Road 4.0 0 0 1 1 1
The White Album 3.5 0 1 0 0 1
Meet the Beatles 3.0 2 2 2 2 2
I have tried to use the count function, but it counts all the values in the field. I can't figure out how to just count the values that match a certain criteria. When I tried to create subqueries, I got an error that said my subqueries where returning a multiple result sets.
Any suggestions would be greatly appreciated,
Chris
I found a solution using sum and case.
