Code Explanation:
The said query in SQL that returns a list of match numbers, the corresponding country names, and the goal score for each match by normal goal.
The query uses a JOIN operation to link the match_details and soccer_country tables based on the common country_id column .
The WHERE clause filters the result set to only include rows where the decided_by column equals 'N', which is a normal goal.
The ORDER BY clause sorts the result set in ascending order based on the match_no column.
