Code Explanation:

The said query in SQL that retrieves information about the player of the match in the final stage of soccer matches, including their name and country from the tables player_mast, match_mast, and soccer_country.
The JOIN clause joins the 'player_mast' table alias as 'a' with the 'match_mast' table alias as 'c' based on the common column "plr_of_match" in 'c' and "player_id" in 'a'. Additionally, only rows where the "play_stage" column in 'c' has the value of 'F' will be joined. Then, the resulting table is joined with the 'soccer_country' table alias as 'b' based on the common column "team_id" in 'a' and "country_id" in 'b'.
