![]() ![]() In our example, we first sorted the result by salary in descending order (higher salaries to lower ones) and then by last name in ascending order within those already sorted records. If you want to use descending order, put the DESC keyword after the appropriate column (in the example, we used descending order for the salary column). The SQLite ORDER BY clause can be used without specifying the ASC or DESC modifier. If you want to use ascending (low to high) order, you can use the ASC keyword this keyword is optional, though, as that is the default order when none is specified. You can modify the sorting order (ascending or descending) separately for each column. Then, after a comma, add the second column (in our example, last_name). I first want to sort based on rating limiting results to 20 and then on this resultset want to further apply sort based on name.

Let’s display all information for each employee but sort the records according to salary in descending order first and then by last name in ascending order. Our database has a table named employee with the following columns: id, first_name, last_name, and salary. As mentioned, many professors use it to teach SQL programming for students in majors such as business, IT, software engineering, and data science. This AND & OR example would return all last_name, and first_name values from the employees table whose the first_name is 'Dave' OR whose last_name is Anderson and the first_name is 'Sarah' OR whose employee_id is 1 and last_name is 'Smith'.You need to display records from a given table sorted by two columns.
