SQL soccer Database: Joins Exercise-37 with Solution
37. From the following tables, write a SQL query to find the player who took the penalty shot number 26. Return match number, country name, player name.
Sample table: penalty_shootout
Sample table: player_mast
Sample table: soccer_country
SELECT match_no, country_name, player_name FROM penalty_shootout a JOIN player_mast b ON a.player_id=b.player_id JOIN soccer_country c ON b.team_id=c.country_id WHERE kick_id=26;
match_no | country_name | player_name ----------+--------------+---------------- 47 | Italy | Graziano Pelle (1 row)
The said query in SQL that retrieves the match number, country name, and player name from the penalty_shootout table, player_mast table, and soccer_country table respectively, for the kick with kick_id 26.
The JOIN statements joins the penalty_shootout table aliased as "a", and the player_mast table aliased as "b" based on the player_id column, and then join the result with the soccer_country table aliased as "c" based on the team_id and country_id columns.
The WHERE clause filters the results to only include rows where the kick_id column is equal to 26.
