3 | 37 | 1221 | 160477 | N | 3
4 | 37 | 1213 | 160298 | Y | 4
5 | 37 | 1221 | 160476 | Y | 5
6 | 37 | 1213 | 160281 | Y | 6
7 | 37 | 1221 | 160470 | Y | 7
8 | 37 | 1213 | 160287 | Y | 8
9 | 37 | 1221 | 160469 | Y | 9
.......
37 | 47 | 1208 | 160166 | Y | 18
Sample Solution:
SQL Code:
-- This SQL query calculates the count of rows in the 'penalty_shootout' table
-- where the 'score_goal' column has the value 'N', indicating goals missed or saved by penalty kicks.
-- It aliases the result as "Goal missed or saved by Penalty Kicks".
SELECT COUNT(*) AS "Goal missed or saved by Penalty Kicks"
-- COUNT(*) is an aggregate function that counts the number of rows in a result set, and the alias is set to "Goal missed or saved by Penalty Kicks".
FROM penalty_shootout
-- 'penalty_shootout' is the name of the table being queried.
WHERE score_goal='N';
-- The WHERE clause filters rows where the 'score_goal' column has the value 'N'.
Sample Output:
Goal missed or saved by Penalty Kicks
