SQL ORDER BY ASC

Introduction

The ORDER BY clause is used in SQL to specify the sorting order of the result set returned by a query. By default, the ORDER BY clause sorts the result set in ascending order. The ASC keyword is used to explicitly specify ascending order.

Syntax

The basic syntax for using ORDER BY in SQL is as follows:

SELECT column1, column2, ...
FROM table_name
ORDER BY column_name ASC;

The ORDER BY clause is used after the FROM clause and before the optional LIMIT or OFFSET clauses.

Example

Consider a table named employees with the following columns: id, name, and salary. We can use the ORDER BY clause to sort the employees by their salaries in ascending order.

SELECT * 
FROM employees
ORDER BY salary ASC;

This will return the employees sorted in ascending order of their salaries.

Usage

The ORDER BY ASC is commonly used when you want to retrieve data in a specific sorted order. It is often used in combination with the SELECT statement to retrieve a sorted result set from a table.

The ASC keyword is optional and can be omitted since ascending order is the default sorting order. However, specifying it explicitly improves the readability and clarity of the code.

Conclusion

The ORDER BY ASC clause is a powerful feature in SQL that allows you to sort the result set in ascending order. It is commonly used to retrieve data in a specific sorted order and can significantly enhance the readability of the code.
