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:
<code class="sql">SELECT 列名 FROM 表名 ORDER BY 列名 ASC/DESC;</code>
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:
<code class="sql">SELECT name FROM customers ORDER BY name ASC;</code>
Sort the order_date
column in the orders
table in descending order:
<code class="sql">SELECT order_date FROM orders ORDER BY order_date DESC;</code>
Note:
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:
<code class="sql">ORDER BY name ASC, age DESC;</code>
