Sample Solution:
SQL Code:
SELECT match_no,
play_stage
FROM match_mast
WHERE match_no=
(SELECT match_no
FROM penalty_shootout
WHERE kick_id=23);
Sample Output:
match_no | play_stage
----------+------------
47 | Q
(1 row)
Code Explanation:
The said query in SQL that selects the match number and play stage for a specific match from the match_mast table in which a penalty kick with ID 23 was taken.
The condition compares the match number in the match_mast table to a subquery that selects the match number from the penalty_shootout table where the kick ID is 23. The subquery is enclosed in parentheses to indicate that it returns a single value. The overall effect of this condition is to retrieve data for the match in which the specified penalty kick was taken.
Alternative Solution:
JOIN with Subquery:
SELECT m.match_no, m.play_stage
FROM match_mast m
JOIN (
SELECT match_no
FROM penalty_shootout
WHERE kick_id = 23
) p ON m.match_no = p.match_no;
Explanation:
This query uses an inner join between the match_mast table and a subquery that selects match_no from penalty_shootout where kick_id is 23. The result is filtered based on matching match_no.
Using EXISTS:
SELECT match_no, play_stage
FROM match_mast m
WHERE EXISTS (
SELECT 1
FROM penalty_shootout p
WHERE p.match_no = m.match_no
AND p.kick_id = 23
);
Explanation:
This query uses the EXISTS keyword to check if there exists at least one row in the penalty_shootout table where both match_no and kick_id match the corresponding columns in match_mast.
Using IN:
SELECT match_no, play_stage
FROM match_mast
WHERE match_no IN (
SELECT match_no
FROM penalty_shootout
WHERE kick_id = 23
);
Explanation:
This query uses the IN operator to filter the match_no in match_mast based on the set of match_no values returned by the subquery that selects match_no where kick_id is 23 in the penalty_shootout table.
