To fetch or display the data in sorted ascending or descending or we use SQL ORDER BY clause. And by default the ORDER BY sorting give support for Ascending order.
SQL SORTING Results
Syntax To use the basic ORDER BY clause follow, this syntax:
SELECT column_name_x .... FROM table_name WHERE [condition] ORDER BY [column1, column2, .. columnN] [ASC | DESC];
Example For the example consider this table of students:
+------+--------+------+--------+-------+----------+ | id | name | age | grades | marks | Trade | +------+--------+------+--------+-------+----------+ | 1 | Luffy | 16 | A | 970 | Science | | 2 | Naruto | 18 | A | 960 | Humanity | | 3 | Zoro | 20 | A | 940 | Commerce | | 4 | Sanji | 21 | B | 899 | Humanity | | 5 | Nami | 17 | B | 896 | Science | | 6 | Robin | NULL | B | 860 | Humanity | +------+--------+------+--------+-------+----------+
Query: Display the Students records and sort them in ascending order by their names.
SELECT * FROM students ORDER BY name;
Output
+------+--------+------+--------+-------+----------+ | id | name | age | grades | marks | Trade | +------+--------+------+--------+-------+----------+ | 1 | Luffy | 16 | A | 970 | Science | | 5 | Nami | 17 | B | 896 | Science | | 2 | Naruto | 18 | A | 960 | Humanity | | 6 | Robin | NULL | B | 860 | Humanity | | 4 | Sanji | 21 | B | 899 | Humanity | | 3 | Zoro | 20 | A | 940 | Commerce | +------+--------+------+--------+-------+----------+
here we did not mention the wildcard ASC or DESC but the SQL show the students record in ascending order according to their names. Query: Display students names and marks, and sort them in descending order by name.
SELECT name, marks FROM students ORDER BY name DESC;
Output
+--------+-------+ | name | marks | +--------+-------+ | Zoro | 940 | | Sanji | 899 | | Robin | 860 | | Naruto | 960 | | Nami | 896 | | Luffy | 970 | +--------+-------+
