I am trying to write a query that connects 3 tables.

The first table is info about each festival The second table is the number of votes for each festival The third table is reviews for each festival

I want to join all 3 tables so i get all the feilds from table1, join table1 with table2 on the festivalid but i also need to count the number of records in table 3 that applys to each festival.

The first 2 tables give me a result becuase they both have data in them but table 3 is empty becuase there are no reviews yet so adding that to my query fives me no results

SELECT  f.*,
        v.total,
        v.votes,
        v.festivalid,
        r.reviewcount as count
    FROM festivals f
INNER
    JOIN vote v
        ON f.festivalid = v.festivalid
INNER 
    JOIN (SELECT festivalid,
                 count(*) as reviewcount
            FROM reviews)
            GROUP BY festivalid) as r

        on r.festivalid = v.festivalid
