In MySQL, you can utilize the EXECUTE statement to execute dynamic SQL queries. Here is a basic example:

SET @sql = 'SELECT * FROM employees WHERE department = ?';
SET @department = 'IT';

PREPARE stmt FROM @sql;
EXECUTE stmt USING @department;
DEALLOCATE PREPARE stmt;

In this example, we first define a variable @sql to store the dynamic SQL statement that will be executed. We then define another variable @department as a parameter passed to the EXECUTE statement.

Proceed by preparing the SQL statement to be executed using the PREPARE statement, then execute the SQL statement with the EXECUTE statement, passing the parameter @department. Finally, release the prepared SQL statement using the DEALLOCATE PREPARE statement.

Please note that the EXECUTE statement and the PREPARE statement are often used together with the SET statement to prepare and execute dynamic SQL statements.
