1. Select the code which shows player and mdate for players which scored during 9th June 2012 to 11th June 2012.

	SELECT player, mdate FROM goal JOIN eteam ON (teamname=id) WHERE mdate IN ('9 June 2012','10 June 2012','11 June 2012')
	SELECT player, mdate FROM goal JOIN game ON (matchid=id) WHERE mdate IN ('9 July 1912','10 July 1912','11 July 1912')
	SELECT player, mdate FROM goal JOIN game ON (matchid=id) WHERE mdate IN ('9 June 2012','10 June 2012','11 June 2012')
	SELECT player, mdate FROM goal JOIN game ON (matchid=id) WHERE mdate LIKE ('9 June 2012','10 June 2012','11 June 2012')
	SELECT stadium, mdate FROM goal JOIN game ON (matchid=id) WHERE mdate IN ('9 June 2012','10 June 2012','11 June 2012')

2. Select the code which shows player, coach and COUNT(*) for players who scored in the first half of a match (0 - 45 minutes).

	SELECT player, coach, COUNT(*) FROM goal JOIN eteam ON (id=teamid) WHERE gtime > 0 AND gtime < 45
	SELECT player, coach, COUNT(*) FROM goal JOIN eteam ON (id=teamid) WHERE gtime > 0 AND gtime < 45 GROUP BY player
	SELECT player, coach, COUNT(*) FROM goal JOIN eteam ON (id=teamid) WHERE gtime < 0 AND gtime > 45 GROUP BY player
	SELECT player, coach, COUNT(*) FROM goal JOIN eteam ON (id=teamid) WHERE gtime > 0 AND gtime < 90 GROUP BY player
	SELECT player, stadium, COUNT(*) FROM goal JOIN game ON (id=matchid) WHERE gtime > 0 AND gtime < 45 GROUP BY player

3. Select the code which shows players, their team and the amount of goals they scored against Greece(GRE).

	SELECT player, COUNT(*), teamid FROM game JOIN goal ON matchid = id WHERE (team1 = "GRE" OR team2 = "GRE") AND teamid != 'GRE' GROUP BY player
	SELECT player, COUNT(*), teamid FROM game JOIN goal ON matchid = id WHERE (team1 = "GRE") AND teamid != 'GRE' GROUP BY player
	SELECT player, COUNT(*), teamid FROM game JOIN goal ON matchid = id WHERE (team1 = "POL" OR team2 = "POL") AND teamid != 'POL' GROUP BY player
	SELECT player, COUNT(*), teamid FROM game JOIN goal WITH matchid = id WHERE (team1 = "GRE" OR team2 = "GRE") AND teamid != 'GRE' GROUP BY player
	SELECT player, teamid FROM game JOIN goal ON matchid = id WHERE (team1 = "GRE" OR team2 = "GRE") AND teamid != 'GRE' GROUP BY player

4. Select the code which would show the player and their team for those who have scored against Poland(POL) in National Stadium, Warsaw.

	SELECT DISTINCT player, teamid FROM game JOIN goal ON matchid = id WHERE stadium = 'National Stadium, Warsaw' AND mdate IN (SELECT mdate FROM game WHERE team1 = 'GER' OR team2 = 'GER')AND teamid != 'GER'
	SELECT DISTINCT player, teamid FROM game JOIN goal ON matchid = id WHERE stadium = 'National Stadium, Warsaw' AND mdate IN (SELECT mdate FROM game WHERE team1 = 'POL' OR team2 = 'POL')AND teamid != 'POL'
	SELECT DISTINCT player, teamid FROM game JOIN goal ON matchid = id WHERE stadium = 'National Stadium, Warsaw' AND teamid != 'POL'
	SELECT DISTINCT player, teamid FROM game JOIN goal ON matchid = id WHERE stadium = 'Stadion Miejski (Wroclaw)' AND mdate IN (SELECT mdate FROM game WHERE team1 = 'POL' OR team2 = 'POL')AND teamid != 'POL'
	SELECT DISTINCT stadium, mdate FROM game JOIN goal ON matchid = id WHERE stadium = 'National Stadium, Warsaw' AND mdate IN (SELECT mdate FROM game WHERE team1 = 'POL' OR team2 = 'POL')AND teamid != 'POL'

5. Select the code which shows the player, their team and the time they scored, for players who have played in Stadion Miejski (Wroclaw) but not against Italy(ITA).

	SELECT DISTINCT player, teamid, gtime FROM game JOIN goal ON matchid = id WHERE stadium = 'National Stadium, Warsaw' AND (team1 != 'ITA' AND team2 !='ITA')
	SELECT DISTINCT player, teamid, gtime FROM game JOIN goal ON matchid = id WHERE stadium = 'Stadion Miejski (Wroclaw)' AND (team1 != 'ESP' AND team2 !='ESP')
	SELECT DISTINCT player, teamid, gtime FROM game JOIN goal ON matchid = id WHERE stadium = 'Stadion Miejski (Wroclaw)' AND (team1 != 'ITA' AND team2 !='ITA')
	SELECT DISTINCT teamid, gtime FROM game JOIN goal ON matchid = id WHERE stadium = 'Stadion Miejski (Wroclaw)' AND (team1 != 'ITA' AND team2 !='ITA')
	SELECT DISTINCT player, teamid, gtime FROM game JOIN goal ON matchid = id WHERE team1 != 'ITA' AND team2 !='ITA'
