In MySQL, % does not represent a decimal.

Detailed description:

In MySQL, % is widely used for wildcard matching and can match any number of any characters. For example:

• LIKE '�c%' matches any string that contains the "abc" substring.
• WHERE name LIKE 'J%' Matches all names starting with the letter "J".

However, % cannot be used to represent decimals. Therefore, the following query will not work correctly:

<code class="sql">SELECT * FROM table WHERE price = 10.5%;</code>

To match decimals, use the BETWEEN operator or comparison operators like >= and <code><= . For example:

SELECT * FROM table WHERE price BETWEEN 10 AND 11;
SELECT * FROM table WHERE price >= 10.5;
