How can you order MySQL data by string length using native functions?

Ordering MySQL Data by String Length with Native Functions

The SQL statement provided attempts to order data by string length using the string_length() function. While string_length() is a valid function, it is not a native MySQL function. As such, it is not recommended for use in MySQL queries.

Instead, MySQL provides the CHAR_LENGTH() function to determine the length of a string. This function returns the number of characters in the string, regardless of their byte length. For multi-byte character sets, CHAR_LENGTH() can differ from LENGTH(), which returns the number of bytes occupied by the string.

To order data by string length in MySQL, use the following syntax:

<code class="sql">SELECT *
FROM table
ORDER BY CHAR_LENGTH(column);</code>

This query will order the rows in the table by the length of the specified column, with shorter strings appearing first.
