Queries :: How To Convert 5 Into 1 Query

I have three tables in a database horse, entry, prize and I am supposed to get the result by one query. A list is required of horses that have career winnings better than that of the average horse. List the horse_id, horse name and the career winnings.

A career winning is the sum of all money won by a horse. The solution must include horses that have not won any prizes when calculating average winnings. Remember to exclude the dummy horse entries for Unknown Sire and Unknown Mare.It is way too complicated for me to get the result by one queries as its nested critera.my solutuin is to create 5 queries with each one getting to the result a bit closer.bit by bit, basing on every previous query, my final query gets the result.Below are my 5 queries in numeric order:

1:SELECT entry.event_id, entry.horse_id, prize.Money, horse.Horse_name FROM horse INNER JOIN (prize INNER JOIN entry ON (prize.event_id = entry.event_id) AND (prize.place = entry.place)) ON horse.Horse_id = entry.Horse_id;

2:SELECT horse.Horse_name, [careerwinningssub1].horse_id, Sum([careerwinningssub1].Money) AS careerwinnings
FROM careerwinningssub1 INNER JOIN horse ON [careerwinningssub1].horse_id=horse.Horse_id
GROUP BY horse.Horse_name, [careerwinningssub1].horse_id
ORDER BY [careerwinningssub1].horse_id;

3:SELECT horse.Horse_id, horse.Horse_name, careerwinningssub2.careerwinnings
FROM horse LEFT JOIN careerwinningssub2 ON horse.Horse_id = careerwinningssub2.horse_id
GROUP BY horse.Horse_id, horse.Horse_name, careerwinningssub2.careerwinnings
HAVING (((horse.Horse_name) Not Like "unknow*"))
ORDER BY horse.Horse_id;
