Combine two mysql group queries - php

Question

I'm making a web app to create tournaments and as i have learned PHP in the course of this project, so my skills aren't probably the best.
I have an identifier in my database day2_semifinal or day2_additional which basically identifies the type of semifinal.
So my first query is:
$numberquery = mysql_query("
SELECT *
FROM tourneyplayers
INNER JOIN results
on (resultid=r_id)
INNER JOIN players
ON (p_id=playerid)
INNER JOIN tourneys
on (T_Id=tourneyid)
WHERE tourneyid='$tourneyid' and
in_day2 = 1 and
day2_semifinal IS NOT NULL
GROUP BY day2_semifinal
ORDER BY agegroupid",$connection);
This will get me all the semifinal groups, i'll iterate over them and query all the players in group:
$semigroup = $group['day2_semifinal'];
$playerQuery = mysql_query("
SELECT *
FROM tourneyplayers
INNER JOIN results
on (r_id=resultid)
INNER JOIN players
on (p_id=playerid)
WHERE tourneyid='$tourneyid' AND
day2_semifinal = '$semigroup' and
in_day2 = 1
ORDER BY day2startplace",$connection);
Now after i've created tables and echoed all the data from player queries for day2_semifinal, i run another query:
$numberquery = mysql_query("SELECT * FROM tourneyplayers INNER JOIN results on (resultid=r_id) INNER JOIN players ON (p_id=playerid) WHERE tourneyid='$tourneyid' and in_day2 = 1 and day2_additional_nosemi IS NOT NULL AND day2_additional_nosemi <> 0 GROUP BY day2_additional_nosemi ORDER BY agegroupid",$connection);
Which is fairly similar to the first one, only thing different is day2_semifinal identifiers have changed to day2_additional. After that query, i'll again, iterate over the day2_additional_nosemi groups and query the players inside of them:
$additionalgroup = $group['day2_additional_nosemi'];
$playerQuery = mysql_query("SELECT * FROM tourneyplayers INNER JOIN results on (r_id=resultid) INNER JOIN players on (p_id=playerid) WHERE tourneyid='$tourneyid' AND day2_additional_nosemi = '$additionalgroup' and in_day2 = 1 ORDER BY day2startplace",$connection);
Now this works, but this creates an issue with ordering, since the first query orders them by agegroupid but only for players in day2_semifinal (and i'd like to have day2_additional players ordered together with day2_semifinal). If i run another query the previous data has already been echoed and ordering is not right. How could i concatenate two $numberquery queries in order to select players after them as well?

Answer 1

I'm answering my own question as i figured out a way to do this. What i did, was removed ORDER BYfrom both queries and created a new query which concatenated the two with UNION:
SELECT * FROM (
SELECT *
FROM tourneyplayers as tp1
INNER JOIN results as r1
on (tp1.resultid=r1.r_id)
INNER JOIN players as p1
ON (p1.p_id=tp1.playerid)
WHERE tp1.tourneyid=96 and
tp1.in_day2 = 1 and
r1.day2_semifinal IS NOT NULL
GROUP BY r1.day2_semifinal
UNION ALL
SELECT *
FROM tourneyplayers as tp2
INNER JOIN results as r2
on (tp2.resultid=r2.r_id)
INNER JOIN players as p2
ON (p2.p_id=tp2.playerid)
WHERE tp2.tourneyid=96 and
tp2.in_day2 = 1 and
r2.day2_additional_nosemi IS NOT NULL AND
r2.day2_additional_nosemi <> 0
GROUP BY r2.day2_additional_nosemi
) t ORDER BY t.agegroupid;
