PHP MySQL Order By

PHP mysql_query() function is used to execute select query with order by clause. Since PHP 5.5, mysql_query() function is deprecated. Now it is recommended to use one of the 2 alternatives.

  • mysqli_query()
  • PDO::__query()

The order by clause is used to fetch data in ascending order or descending order on the basis of column.

Let's see the query to select data from emp4 table in ascending order on the basis of name column.

snippet
SELECT * FROM emp4 order by name

Let's see the query to select data from emp4 table in descending order on the basis of name column.

snippet
SELECT * FROM emp4 order by name desc
