WHERE stop2_sec IN (
SELECT MAX(stop2_sec) 
FROM match_mast);

Code Explanation:

The said query in SQL that selects the match number, country name, and stoppage time in seconds for all matches where the stoppage time in seconds is equal to the maximum stoppage time in seconds across all matches from the tables match_mast, match_details, and soccer_country.
The JOIN clause is used to join the tables match_mast and match_details table based on the match_no column and join the soccer_country table with the results of previous join based on team_id columns of match_details table and country_id column of soccer_country table.
The WHERE clause filters the results to only show matches where the stop2_sec column in the match_mast table is equal to the maximum value of stop2_sec in the same table. The subquery inside the WHERE clause is used to get the maximum value of stop2_sec from the match_mast table.
