Sample Solution:
SQL Code:
-- This SQL query retrieves the country names from the 'soccer_country' table
-- for teams that participated in the 'F' (Finals) stage and are not Portugal.
SELECT country_name
-- Selects the 'country_name' column.
FROM soccer_country
-- 'soccer_country' is the name of the table being queried.
WHERE country_id = (
-- The WHERE clause filters rows where 'country_id' matches the result of the subquery.
SELECT team_id
-- The subquery selects the 'team_id' column.
FROM match_details
-- 'match_details' is the name of the table involved in the subquery.
WHERE play_stage = 'F'
-- Further filters rows in the subquery where 'play_stage' is 'F' (Finals).
AND team_id <> (
-- Further filters rows in the subquery where 'team_id' is not equal to the country ID for Portugal in the sub-subquery.
SELECT country_id
-- This sub-subquery selects the 'country_id' column.
FROM soccer_country
-- 'soccer_country' is the name of the table involved in the sub-subquery.
WHERE country_name = 'Portugal'
-- Further filters rows in the sub-subquery where 'country_name' is 'Portugal'.
)
);
Sample Output:
country_name -------------- France (1 row)
Code Explanation:
The said query in SQL that selects the names of countries that played in the soccer final but did not have a team with the name "Portugal".
The WHERE clause of the outer query filters the rows where the country_id is equal to the result of a subquery.
The subquery selects the team_id from the match_details table where the play_stage is 'F' (final) and the team_id is not equal to the country_id of the row in the soccer_country table where the country_name is 'Portugal'.
In other words, the query is finding the country names of teams that played in the final, but not Portugal.
Alternative Solutions:
Using JOIN and WHERE:
SELECT sc.country_name
FROM soccer_country sc
JOIN match_details md ON sc.country_id = md.team_id
WHERE md.play_stage = 'F'
AND md.team_id <> (
SELECT country_id
FROM soccer_country
WHERE country_name = 'Portugal'
);
Explanation:
This query uses JOIN to combine soccer_country and match_details based on country_id and team_id. It then applies conditions in the WHERE clause to filter for matches in the final stage (play_stage='F') and ensures that the team is not Portugal.
Using EXISTS:
SELECT country_name
FROM soccer_country sc
WHERE EXISTS (
SELECT 1
FROM match_details md
WHERE md.team_id = sc.country_id
AND md.play_stage = 'F'
AND md.team_id <> (
SELECT country_id
FROM soccer_country
WHERE country_name = 'Portugal'
)
);
Explanation:
This query uses a correlated subquery with EXISTS to check if there exists a match in the final stage (play_stage='F') where the team is not Portugal.
Using JOIN and Subqueries:
SELECT sc.country_name
FROM soccer_country sc
JOIN match_details md ON sc.country_id = md.team_id
WHERE md.play_stage = 'F'
AND md.team_id NOT IN (
SELECT country_id
FROM soccer_country
WHERE country_name = 'Portugal'
);
Explanation:
This query uses a subquery with NOT IN to find countries that are not Portugal. It then applies conditions to filter for matches in the final stage.
Using JOIN and Subqueries with ANY:
SELECT sc.country_name
FROM soccer_country sc
JOIN match_details md ON sc.country_id = md.team_id
WHERE md.play_stage = 'F'
AND md.team_id <> ANY (
SELECT country_id
FROM soccer_country
WHERE country_name = 'Portugal'
);
Explanation:
This query uses the <> ANY syntax to achieve the same result as NOT IN. It filters for matches in the final stage and ensures the team is not Portugal.
