Sample Solution:
-- This SQL query retrieves the count of goals for each match, grouping the results by 'match_no' and ordering them in ascending order.
SELECT match_no, COUNT(*)
-- Selects the 'match_no' column and the count of rows for each group.
FROM goal_details
-- 'goal_details' is the name of the table being queried.
GROUP BY match_no
-- Groups the results by the 'match_no' column.
ORDER BY match_no;
-- Orders the result set based on the 'match_no' column in ascending order.
Sample Output:
match_no | count

Code Explanation:
The said query in SQL that selects the "match_no" and the count of rows from the 'goal_details' table, grouped by the "match_no" column, and sorted the result set in ascending order based on the "match_no" column.
The "GROUP BY" clause groups the rows in the 'goal_details' table by the "match_no" column. "COUNT" is a function that counts the number of rows in each of the groups. As a result of the "ORDER BY" clause, the groups are sorted in ascending order based upon the "match_no" column within the group.
