SQL Backend

[Antar1011]

Resolves #18

SQLite implementation of a backend for Onix.

Before merging I might want to add some "pipeline" tests that verify expected operation from start to finish

In case anyone's interested, this is the compiled SQL query for get_usage_by_species:

SELECT anon_1.species, sum(anon_1.weight) AS sum 
FROM (SELECT anon_2.bid AS bid, anon_2.side AS side, anon_2.weight AS weight, count(anon_2.slot) AS count, anon_2.species AS species 
FROM (SELECT anon_3.bid AS bid, anon_3.side AS side, anon_3.weight AS weight, teams.idx AS slot, teams.sid AS sid, CASE group_concat(formes.species) WHEN ? THEN ? WHEN ? THEN ? WHEN ? THEN ? WHEN ? THEN ? ELSE ? || group_concat(formes.species) END AS species 
FROM (SELECT anon_4.bid AS bid, anon_4.side AS side, anon_4.pid AS pid, anon_4.tid AS tid, CASE WHEN (ifnull(anon_4.rprd, ?) > ?) THEN ? ELSE weight(ifnull(anon_4.rpr, ?), ifnull(anon_4.rprd, ?), ?) END AS weight 
FROM (SELECT anon_5.id AS bid, battle_players.side AS side, battle_players.pid AS pid, battle_players.tid AS tid, battle_players.w AS w, battle_players.l AS l, battle_players.t AS t, battle_players.elo AS elo, battle_players.r AS r, battle_players.rd AS rd, battle_players.rpr AS rpr, battle_players.rprd AS rprd 
FROM (SELECT battle_infos.id AS id 
FROM battle_infos 
WHERE battle_infos.format = ? AND battle_infos.date BETWEEN ? AND ? AND battle_infos.turns >= ?) AS anon_5 JOIN battle_players ON anon_5.id = battle_players.bid) AS anon_4) AS anon_3 JOIN teams ON anon_3.tid = teams.tid JOIN moveset_forme ON teams.sid = moveset_forme.sid JOIN formes ON moveset_forme.fid = formes.id GROUP BY anon_3.bid, anon_3.side, teams.idx) AS anon_2 GROUP BY anon_2.bid, anon_2.side, anon_2.species) AS anon_1 GROUP BY anon_1.species ORDER BY sum DESC

Crud. This structure doesn't support ordering ('camerupt,cameruptmegax' is just a matter of alphabetical sorting, but how can we do 'charizardmegay,charizardmegax'?)

[Antar1011]

I can handle this the same way it's handled for team members (in fact, it looks like there's a way to handle this more cleanly), but I honestly think this might be the impetus I need to tackle #48.

[Antar1011]

LOL. I've been doing this kind of ordering all over the place (see: battle_players), but w/e--I feel like the core approach is cleaner
