Alphabetical sorting in SQL

In SQL, you can use the ORDER BY clause to sort the data in the result set in alphabetical order.

Syntax:

SELECT 列名
FROM 表名
ORDER BY 列名 ASC/DESC;
Copy after login

Parameters:

  • Column name: To press Sorted columns
  • ASC: Sort in ascending order (small to large)
  • DESC: Sort in descending order (large to small)

Example:

Sort the name column in the customers table in ascending order:

SELECT name
FROM customers
ORDER BY name ASC;
Copy after login

Sort the order_date column in the orders table in descending order:

SELECT order_date
FROM orders
ORDER BY order_date DESC;
Copy after login

Note:

  • Default Below, the ORDER BY clause sorts in ascending order.
  • If you want to sort multiple columns, you can use commas to separate the column names. For example:

    ORDER BY name ASC, age DESC;
    Copy after login
