SQL Exercise: Goals scored by each player during normal play
SQL soccer Database: Joins Exercise-3 with Solution
3. From the following table, write a SQL query to count the number of goals scored by each player within a normal play schedule. Group the result set on player name and country name and sorts the result-set according to the highest to the lowest scorer. Return player name, number of goals and country name.
Sample table: goal_details
Sample table: player_mast
Sample table: soccer_country
Sample Solution:
SQL Code:
SELECT player_name,count(*),country_name
FROM goal_details a
JOIN player_mast b ON a.player_id=b.player_id
JOIN soccer_country c ON a.team_id=c.country_id
WHERE goal_schedule = 'NT'
GROUP BY player_name,country_name
ORDER BY count(*) DESC;
Sample Output:
player_name | count | country_name -------------------------+-------+--------------------- Antoine Griezmann | 5 | France Cristiano Ronaldo | 3 | Portugal Gareth Bale | 3 | Wales Olivier Giroud | 3 | France Alvaro Morata | 3 | Spain Nani | 3 | Portugal Ivan PeriSic | 2 | Croatia Radja Nainggolan | 2 | Belgium Birkir Bjarnason | 2 | Iceland Gareth McAuley | 2 | Northern Ireland Romelu Lukaku | 2 | Belgium Hal Robson-Kanu | 2 | Wales Balazs Dzsudzsak | 2 | Hungary Kolbeinn Sigthorsson | 2 | Iceland Robbie Brady | 2 | Republic of Ireland Bogdan Stancu | 2 | Romania Mario Gomez | 2 | Germany Jakub Blaszczykowski | 2 | Poland Dimitri Payet | 2 | France Adam Szalai | 1 | Hungary Ozan Tufan | 1 | Turkey Aaron Ramsey | 1 | Wales Gerard Pique | 1 | Spain Jamie Vardy | 1 | England Arnor Ingvi Traustason | 1 | Iceland Robert Lewandowski | 1 | Poland Zoltan Gera | 1 | Hungary Birkir Saevarsson | 1 | Iceland Arkadiusz Milik | 1 | Poland Michy Batshuayi | 1 | Belgium Eder | 1 | Italy Julian Draxler | 1 | Germany Neil Taylor | 1 | Wales Paul Pogba | 1 | France Eden Hazard | 1 | Belgium Nolito | 1 | Spain Giorgio Chiellini | 1 | Italy Leonardo Bonucci | 1 | Italy Nikola Kalinic | 1 | Croatia Toby Alderweireld | 1 | Belgium Sam Vokes | 1 | Wales Zoltan Stieber | 1 | Hungary Admir Mehmedi | 1 | Switzerland Armando Sadiku | 1 | Albania Jon Dadi Bodvarsson | 1 | Iceland Ivan Rakitic | 1 | Croatia Wayne Rooney | 1 | England Eric Dier | 1 | England Fabian Schar | 1 | Switzerland Ciaran Clark | 1 | Republic of Ireland Ondrej Duda | 1 | Slovakia TomasNecid | 1 | Czech Republic Mesut ozil | 1 | Germany Wes Hoolahan | 1 | Republic of Ireland Alessandro Schopf | 1 | Austria Luka Modric | 1 | Croatia Thomas Muller | 1 | Germany Burak Yilmaz | 1 | Turkey Gylfi Sigurdsson | 1 | Iceland Xherdan Shaqiri | 1 | Switzerland Renato Sanches | 1 | Portugal Vladimir Weiss | 1 | Slovakia Ashley Williams | 1 | Wales Marek Hamsik | 1 | Slovakia Yannick Carrasco | 1 | Belgium Milan Skoda | 1 | Czech Republic Jerome Boateng | 1 | Germany Axel Witsel | 1 | Belgium Denis Glushakov | 1 | Russia Emanuele Giaccherini | 1 | Italy (70 rows)
Code Explanation:
The given query in SQL that returns a list of player names, the corresponding country names, and the number of goals scored by each player for their country during normal time
The JOIN operations joins the goal_details table with the player_mast and soccer_country tables based on the common player_id and country_id columns, respectively. The selected columns are player_name, country_name, and count(), where count() is an aggregate function that counts the number of rows in the grouped result set.
The WHERE clause filters the result set to only include rows where the goal_schedule column equals 'NT', which likely stands for "normal time".
The GROUP BY clause groups the result set by player_name and country_name, meaning that each unique combination of player and country is treated as a separate group.
The ORDER BY clause sorts the result set in descending order based on the count(*) column, which represents the number of goals scored by each player for their country during normal time.
