eteam JOIN game ON (id=team2)
eteam JOIN goal ON (teamid=id)
game JOIN goal ON (id=matchid)
game JOIN goal ON (team1=teamid OR team2=teamid)
2. You JOIN the tables
goal and
eteam in an SQL statement. Indicate the list of column names that may be used in the SELECT line:
gtime, mdate, stadium, matchid
mdate, stadium, id
matchid, teamid, player, gtime, id, teamname, coach
matchid, teamid, player, gtime, mdate, stadium, team1
stadium, team1, team2
3. Select the code which shows players, their team and the amount of goals they scored against Greece(GRE).
SELECT player, teamid, COUNT(*)
FROM game JOIN goal ON matchid = id
WHERE (team1 = "GRE" OR team2 = "GRE")
AND teamid != ‘GRE‘
GROUP BY player, teamid
SELECT player, teamid, COUNT(*)
FROM game JOIN goal ON matchid = id
WHERE (team1 = "GRE") AND teamid != ‘GRE‘
GROUP BY player, teamid
SELECT player, teamid, COUNT(*)
FROM game JOIN goal ON matchid = id
WHERE (team1 = "POL" OR team2 = "POL")
AND teamid != ‘POL‘
GROUP BY player, teamid
SELECT player, teamid, COUNT(*)
FROM game JOIN goal WITH matchid = id
WHERE (team1 = "GRE" OR team2 = "GRE")
AND teamid != ‘GRE‘
GROUP BY player, teamid
SELECT player, teamid
FROM game JOIN goal ON matchid = id
WHERE (team1 = "GRE" OR team2 = "GRE")
AND teamid != ‘GRE‘
GROUP BY player, teamid
4. Select the result that would be obtained from this code:
SELECT DISTINCT teamid, mdate
FROM goal JOIN game on (matchid=id)
WHERE mdate = ‘9 June 2012‘
| DEN |
9 June 2012 |
| GER |
9 June 2012 |
| DEN |
9 June 2012 |
| DEN |
9 June 2012 |
| POL |
9 June 2012 |
| RUS |
9 June 2012 |
| RUS |
9 June 2012 |
| GRE |
9 June 2012 |
| RUS |
9 June 2012 |
| CZE |
9 June 2012 |
5. 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 (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 (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 (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 (team1 = ‘POL‘ OR team2 = ‘POL‘)
AND teamid != ‘POL‘
6. 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 (( teamid = team2 AND team1 != ‘ITA‘) OR ( teamid = team1 AND team2 != ‘ITA‘))
SELECT DISTINCT player, teamid, gtime
FROM game JOIN goal ON matchid = id
WHERE stadium = ‘Stadion Miejski (Wroclaw)‘
AND (( teamid = team2 AND team1 != ‘ESP‘) OR ( teamid = team1 AND team2 != ‘ESP‘))
SELECT DISTINCT player, teamid, gtime
FROM game JOIN goal ON matchid = id
WHERE stadium = ‘Stadion Miejski (Wroclaw)‘
AND (( teamid = team2 AND team1 != ‘ITA‘) OR ( teamid = team1 AND team2 != ‘ITA‘))
SELECT DISTINCT teamid, gtime
FROM game JOIN goal ON matchid = id
WHERE stadium = ‘Stadion Miejski (Wroclaw)‘
AND (( teamid = team2 AND team1 != ‘ITA‘) OR ( teamid = team1 AND team2 != ‘ITA‘))
SELECT DISTINCT player, teamid, gtime
FROM game JOIN goal ON matchid = id
WHERE team1 != ‘ITA‘ AND team2 !=‘ITA‘
7. Select the result that would be obtained from this code:
SELECT teamname, COUNT(*)
FROM eteam JOIN goal ON teamid = id
GROUP BY teamname
HAVING COUNT(*) < 3
