Sample Solution:
SQL Code:
SELECT a.match_no,
b.player_name,
a.kick_no
FROM penalty_shootout a,
player_mast b
WHERE a.player_id=b.player_id
AND kick_no=7
AND match_no=
(SELECT match_no
FROM penalty_shootout
WHERE team_id =
(SELECT country_id
FROM soccer_country
WHERE country_name='Portugal' )
GROUP BY match_no)
GROUP BY match_no,
player_name,
kick_id;
Sample Output:
match_no | player_name | kick_no
----------+-------------+---------
45 | Nani | 7
(1 row)
Code Explanation:
The said query in SQL that selects the match number, player name, and kick number for penalty shootout kicks that occurred in the 7th round of penalty kicks for a specific match
from penalty_shootout and player_mast table in which Portugal was one of the teams playing.
The first condition joins the two tables based on the player_id column.
The second condition specified in the query should only retrieve data for the 7th kick in the penalty shootout.
The third condition retrieves data for a specific match in which Portugal was one of the teams playing. This condition uses a subquery to find the match_no for the specified match. The GROUP BY clause groups the data by match_no, player_name, and kick_id.
Alternative Solution:
Subquery with MAX and HAVING:
SELECT a.match_no, b.player_name, a.kick_no
FROM penalty_shootout a
JOIN player_mast b ON a.player_id = b.player_id
WHERE a.kick_no = 7
AND a.match_no = (
SELECT match_no
FROM penalty_shootout
WHERE team_id = (
SELECT country_id
FROM soccer_country
WHERE country_name = 'Portugal'
)
GROUP BY match_no
HAVING COUNT(*) > 0
)
GROUP BY a.match_no, b.player_name, a.kick_no;
JOIN with Subquery:
SELECT a.match_no, b.player_name, a.kick_no
FROM penalty_shootout a
JOIN player_mast b ON a.player_id = b.player_id
JOIN (
SELECT match_no
FROM penalty_shootout
WHERE team_id = (
SELECT country_id
FROM soccer_country
WHERE country_name = 'Portugal'
)
GROUP BY match_no
HAVING COUNT(*) > 0
) c ON a.match_no = c.match_no
WHERE a.kick_no = 7
GROUP BY a.match_no, b.player_name, a.kick_no;
Using EXISTS:
SELECT a.match_no, b.player_name, a.kick_no
FROM penalty_shootout a
JOIN player_mast b ON a.player_id = b.player_id
WHERE a.kick_no = 7
AND EXISTS (
SELECT 1
FROM penalty_shootout p
WHERE p.match_no = a.match_no
AND p.team_id = (
SELECT country_id
FROM soccer_country
WHERE country_name = 'Portugal'
)
)
GROUP BY a.match_no, b.player_name, a.kick_no;
Using JOIN with Subquery:
SELECT a.match_no, b.player_name, a.kick_no
FROM penalty_shootout a
JOIN player_mast b ON a.player_id = b.player_id
JOIN (
SELECT match_no
FROM penalty_shootout
WHERE team_id = (
SELECT country_id
FROM soccer_country
WHERE country_name = 'Portugal'
)
GROUP BY match_no
HAVING COUNT(*) > 0
) c ON a.match_no = c.match_no
WHERE a.kick_no = 7
GROUP BY a.match_no, b.player_name, a.kick_no;
