python-mysqlHow can I use the "order by" statement in Python to sort data in a MySQL database?
The ORDER BY
statement in Python can be used to sort data in a MySQL database. The syntax for using ORDER BY
is as follows: SELECT * FROM table_name ORDER BY column_name [ASC|DESC];
.
The ORDER BY
statement is used to sort the results of a SELECT
statement in either ascending or descending order. The ASC
keyword is used to sort the results in ascending order, while the DESC
keyword is used to sort the results in descending order.
For example, the following code block can be used to sort a table of student grades in descending order:
SELECT * FROM student_grades ORDER BY grade DESC;
The output of the above code would be a list of student grades sorted in descending order.
