How can the SQL syntax error in the query string be resolved?

To resolve the SQL syntax error in the query string, you should carefully review the SQL query for any syntax errors such as missing quotes, incorrect table or column names, or improper formatting. Make sure to properly escape any user input to prevent SQL injection attacks. Additionally, consider using prepared statements or ORM libraries to handle SQL queries more securely.

// Example PHP code snippet to resolve SQL syntax error
$query = "SELECT * FROM users WHERE username = 'John'";
$result = mysqli_query($connection, $query);

if ($result) {
    // Process the query result
} else {
    echo "Error: " . mysqli_error($connection);
}
