How to Use the LIMIT Keyword with MySQL Prepared Statements?

LIMIT Keyword on MySQL with Prepared Statement

The LIMIT clause, used to restrict the number of result rows in MySQL queries, poses a challenge when employing prepared statements. The PDOStatement::execute() function handles input parameters as strings by default. This raises an issue when using the LIMIT keyword since uncasted strings will trigger a parse error.

To resolve this problem, several options are available:

• Bind Parameters Individually: By assigning types to parameters, you can ensure proper casting. Utilize PDO::PARAM_INT for integer parameters.
• Exclude Parameters: Avoid passing LIMIT values as parameters and instead incorporate them directly into the query string using sprintf() or similar methods.
• Disable Emulated Prepares: The MySQL driver has a feature that adds quotes around numerical arguments. This can be disabled using PDO::ATTR_EMULATE_PREPARES.

By following these methods, you can effectively use the LIMIT keyword within MySQL prepared statements.
