How do I convert data types

In MySQL, converting data types can be essential for ensuring that your queries return the desired results. Below, you can find a simple explanation and example of how to convert data types using the CAST() and CONVERT() functions.

CAST() and CONVERT() are commonly used functions in MySQL to change the data type of a value to another type.


        // Example of using CAST() and CONVERT() in MySQL
        $query = "SELECT 
                    name, 
                    CAST(age AS CHAR) AS age_in_string, 
                    CONVERT(salary, DECIMAL(10,2)) AS salary_in_decimal 
                  FROM employees";
