Question

I have an app which allows users to vote and have two tables

Video

|id|uri_code|filename|created_on|deleted|

Votes

|id|video_id|ip|created_on|

I’d like to be able to select all the video information and have the total number of votes for each video, is this possible with an sql statement or would I be best off doing it with the server side code?

Answer 1

It’s certainly possible with SQL – this sort of thing is exactly what SQL is great at! You want to “group” a count of all votes by video, so the GROUP BY clause is exactly what you’re after:

SELECT Video.*, COUNT(*)
FROM Video JOIN Votes ON Votes.video_id = Video.id
GROUP BY Video.id;
