MySQL SELECT two records from other table?

NOTE: This is not the same as this question, as I need to get data from two other records, not two fields from one one other record!

MySQL newb. I have two tables, and I want to get data from both of them so I have the following:

wp_bowling_fixtures

fixture_id | fixture_date | home_team_id | away_team_id
-----------+--------------+--------------+-------------
1          | 2017-12-12   | 1            | 2
2          | 2017-12-12   | 3            | 4
3          | 2017-12-12   | 5            | 6
4          | 2017-12-12   | 7            | 8
5          | 2017-12-12   | 9            | 10

wp_bowling_teams

team_id | name   | division | archived
--------+--------+----------+---------
1       | Team A | 1        | 0
2       | Team B | 1        | 0
3       | Team C | 2        | 1
4       | Team D | 2        | 0
5       | Team E | 3        | 0
6       | Team F | 3        | 0
7       | Team G | 4        | 0
8       | Team H | 4        | 1
9       | Team I | 4        | 0
10      | Team J | 4        | 0

The result I want a SELECT query to produce:

fixture_id | fixture_date | home_team_id | home_team_name | home_team_archived | home_team_division | away_team_id | away_team_name | away_team_archived | away_team_division
-----------+--------------+--------------+----------------+--------------------+--------------------+--------------+----------------+--------------------+-------------------
1          | 2017-12-12   | 1            | Team A         | 0                  | 1                  | 2            | Team B         | 0                  | 1

I also want it ordered by fixture_date DESC, home_team_division ASC, home_team_name ASC.

Hope that makes sense.

TIA,

Nick.

SELECT f.fixture_id, f.fixture_date, h.team_id as home_team_id, h.name as home_team_name, h.archived as home_team_archived, h.division as home_team_division, a.team_id as away_team_id, a.name as away_team_name, a.archived as away_team_archived, a.division as away_team_division FROM wp_bowling_fixtures f, wp_bowling_teams h, wp_bowling_teams a where f.home_team_id = h.team_id and f.away_team_id = a.team_id order by f.fixture_date desc, h.division asc, h.name asc;

Works.

Nothing in sql stops you joining a table twice but if you do so you must alias them .

You're looking for a query that uses 

fixtures f 
JOIN teams h ON f.home_team_id = h.team_id
JOIN teams a ON f.away_team_id = a.team_id

I gave the teams h (for home) and a (for away) aliases so I could tell them apart. Give it a go at filling it out
