The MYSQL ORDER BY Clause is used to sort the records in ascending or descending order.
Syntax:
SELECT expressions FROM tables [WHERE conditions] ORDER BY expression [ ASC | DESC ];
expressions: It specifies the columns that you want to retrieve.
tables: It specifies the tables, from where you want to retrieve records. There must be at least one table listed in the FROM clause.
WHERE conditions: It is optional. It specifies conditions that must be fulfilled for the records to be selected.
ASC: It is optional. It sorts the result set in ascending order by expression (default, if no modifier is provider).
DESC: It is also optional. It sorts the result set in descending order by expression.
If you use MySQL ORDER BY clause without specifying the ASC and DESC modifier then by default you will get the result in ascending order.
Execute the following query:
SELECT * FROM officers WHERE address = 'Lucknow' ORDER BY officer_name;
Output:
Let's take an example to retrieve the data in ascending order.
Execute the following query:
SELECT * FROM officers WHERE address = 'Lucknow' ORDER BY officer_name ASC;
Output:
SELECT * FROM officers WHERE address = 'Lucknow' ORDER BY officer_name DESC;
Execute the following query:
SELECT officer_name, address FROM officers WHERE officer_id < 5 ORDER BY officer_name DESC, address ASC;
Output:
