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')

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

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

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'
