Sample Solution:
SQL Code:
-- This query selects specific columns from the match_mast, match_details, and soccer_country tables.
SELECT
a.match_no, -- Selecting the match number from the match_mast table aliased as 'a'
c.country_name, -- Selecting the country name from the soccer_country table aliased as 'c'
a.stop2_sec -- Selecting the stoppage time from the match_mast table aliased as 'a'
FROM
match_mast a -- Specifying the match_mast table with an alias 'a'
JOIN
match_details b ON a.match_no = b.match_no -- Joining the match_details table with the match_mast table based on the match number
JOIN
soccer_country c ON b.team_id = c.country_id -- Joining the soccer_country table with the match_details table based on the team_id
WHERE
(2 - 1) = ( -- Checking if the difference between 2 and 1 is equal to
SELECT
COUNT(DISTINCT(b.stop2_sec)) -- Counting the distinct stoppage times from the match_mast table aliased as 'b'
FROM
match_mast b -- Specifying the match_mast table for the subquery aliased as 'b'
WHERE
b.stop2_sec > a.stop2_sec -- Filtering stoppage times greater than the stoppage time in the main query
);
Sample Output:
match_no | country_name | stop2_sec

15 | France | 374
15 | Albania | 374
(2 rows)
Code Explanation:
The said query in SQL that retrieves data from the tables match_mast, match_details, and soccer_country. It selects the match number, country name, and stop2_sec columns from the respective tables.
The JOIN clause joins the table match_mast on match_no with match_details, and match_details on team_id with soccer_country.
Filters the data based on the condition that the difference between the number 2 and the number 1 is equal to the count of distinct stop2_sec values in match_mast table that are greater than the stop2_sec value in the current row of match_mast table.
Alternative Solutions:
Using a Self-Join:
-- This query selects specific columns from the match_mast, match_details, and soccer_country tables.
SELECT
a.match_no, -- Selecting the match number from the match_mast table aliased as 'a'
c.country_name, -- Selecting the country name from the soccer_country table aliased as 'c'
a.stop2_sec -- Selecting the stoppage time from the match_mast table aliased as 'a'
FROM
match_mast a -- Specifying the match_mast table with an alias 'a'
JOIN
match_details b ON a.match_no = b.match_no -- Joining the match_details table with the match_mast table based on the match number
JOIN
soccer_country c ON b.team_id = c.country_id -- Joining the soccer_country table with the match_details table based on the team_id
JOIN
match_mast d ON a.stop2_sec < d.stop2_sec -- Joining the match_mast table with itself to find matches with stoppage time greater than the current match
GROUP BY
a.match_no, c.country_name, a.stop2_sec -- Grouping the results by match number, country name, and stoppage time
HAVING
-- Filtering the groups where there's exactly one distinct stoppage time greater than the current match's stoppage time
COUNT(DISTINCT d.stop2_sec) = 1;
Explanation:
This query uses a self-join on match_mast (alias d) with a condition that compares stop2_sec. It then groups the results by match_no, country_name, and stop2_sec. The HAVING clause ensures that only matches with a single unique stop2_sec value are selected.
Using a JOIN with Subquery:
-- This query selects specific columns from the match_mast, match_details, and soccer_country tables.
SELECT
a.match_no, -- Selecting the match number from the match_mast table aliased as 'a'
c.country_name, -- Selecting the country name from the soccer_country table aliased as 'c'
a.stop2_sec -- Selecting the stoppage time from the match_mast table aliased as 'a'
FROM
match_mast a -- Specifying the match_mast table with an alias 'a'
JOIN
match_details b ON a.match_no = b.match_no -- Joining the match_details table with the match_mast table based on the match number
JOIN
soccer_country c ON b.team_id = c.country_id -- Joining the soccer_country table with the match_details table based on the team_id
JOIN
(
-- Subquery to select distinct stoppage times
SELECT DISTINCT
stop2_sec -- Selecting distinct stoppage times
FROM
match_mast
) d ON a.stop2_sec < d.stop2_sec -- Joining the distinct stoppage times with the match_mast table to find matches with stoppage time greater than the current match
GROUP BY
a.match_no, c.country_name, a.stop2_sec -- Grouping the results by match number, country name, and stoppage time
HAVING
-- Filtering the groups where there's exactly one record, indicating that the stoppage time is unique
COUNT(*) = 1;
Explanation:
This query uses a subquery (d) to get a distinct list of stop2_sec values. It then joins this subquery with the main tables and applies the condition b.stop2_sec < d.stop2_sec. The result is grouped and only matches with a count of 1 are selected.
