SQL Count the Rows with Order By Clause
The ORDER BY clause is used to sort the results of a SQL query by one or more columns. When used in conjunction with the COUNT() function, the ORDER BY clause can be used to sort the results by the count of a particular column.
For example, let’s say we have a student’s table with columns id, name, email, and phone. We want to count the number of students in each phone and then sort the results in descending order by the count of students in each phone. We can use the following SQL query:
Query:
SELECT phone, COUNT(*) AS num_students
FROM students
GROUP BY phone
ORDER BY num_students ASC;
Output:
