Final answer:
To find goals scored by players named Mario, perform a SQL query that joins the 'goals', 'players', and 'matches' tables, using the LIKE operator to filter for the player's name. Include team1 and team2 in the SELECT statement to display the teams for each goal.
Step-by-step explanation:
To show the team1, team2, and player for every goal scored by a player named Mario, you need to run a SQL query that joins the appropriate tables together. The SQL query should include a JOIN clause (which might be an INNER JOIN, LEFT JOIN, etc., depending on your previous question) and a WHERE clause to filter the results for players with the name that starts with 'Mario'.
Here's an example of what the SQL query might look like:
SELECT matches.team1, matches.team2, players.player
JOIN matches ON goals.match_id = matches.id
This query assumes that there are three tables: 'goals', 'players', and 'matches', and that these tables are related through a 'player_id' field in the 'goals' table that relates to an 'id' in the 'players' table, and a 'match_id' in the 'goals' table that relates to an 'id' in the 'matches' table. The WHERE clause filters for player names that begin with 'Mario'.
