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 ----------+------- 1 | 3 2 | 1 3 | 3 4 | 2 5 | 1 6 | 1 7 | 2 8 | 1 9 | 2 10 | 2 11 | 2 12 | 2 13 | 3 14 | 2 15 | 2 16 | 3 17 | 2 19 | 1 20 | 4 21 | 3 22 | 3 23 | 2 25 | 1 27 | 3 29 | 1 30 | 1 31 | 2 32 | 3 33 | 3 34 | 6 35 | 1 36 | 1 37 | 2 38 | 1 39 | 1 40 | 3 41 | 3 42 | 4 43 | 2 44 | 3 45 | 2 46 | 4 47 | 2 48 | 7 49 | 2 50 | 2 51 | 1 (47 rows)
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.
