Code Explanation:
The said query in SQL that selects the name of the countries whose teams have scored in the match with the highest audience. The innermost subquery retrieves the maximum audience from the match_mast table. The middle subquery retrieves the match number corresponding to that maximum audience. Finally, the outermost query retrieves the country names of the teams that scored in that match.
Alternative Solutions:
Using JOIN and WHERE:
SELECT DISTINCT sc.country_name
FROM soccer_country sc
JOIN goal_details gd ON sc.country_id = gd.team_id
WHERE gd.match_no IN (
SELECT mm.match_no
FROM match_mast mm
WHERE mm.audence = (
SELECT MAX(audence)
FROM match_mast
)
);
Explanation:
This query uses INNER JOIN to connect the soccer_country and goal_details tables. It then uses WHERE to filter for matches that have the maximum audience, and selects the corresponding country names.
Using EXISTS:
SELECT country_name
FROM soccer_country sc
WHERE EXISTS (
SELECT 1
FROM goal_details gd
WHERE gd.team_id = sc.country_id
AND gd.match_no = (
SELECT match_no
FROM match_mast
WHERE audence = (
SELECT MAX(audence)
FROM match_mast
)
)
);
Explanation:
This query uses EXISTS with correlated subqueries to find countries that have participated in matches with the maximum audience.
Using INNER JOIN with Subqueries:
SELECT DISTINCT sc.country_name
FROM soccer_country sc
JOIN goal_details gd ON sc.country_id = gd.team_id
WHERE gd.match_no IN (
SELECT match_no
FROM match_mast
WHERE audence = (
SELECT MAX(audence)
FROM match_mast
)
);
Explanation:
This query uses INNER JOIN with subqueries to find countries that have participated in matches with the maximum audience.
