What are the drawbacks of using ASCII values for bit fields in MySQL databases and how can developers optimize data retrieval in such cases?

Using ASCII values for bit fields in MySQL databases can lead to increased storage space and slower data retrieval. To optimize data retrieval in such cases, developers can use bitwise operators in their SQL queries to efficiently manipulate and retrieve the data. 

// Example of optimizing data retrieval for ASCII values in MySQL bit fields using bitwise operators
$query = "SELECT * FROM table_name WHERE (bit_field & 1) = 1";
$result = mysqli_query($connection, $query);

// Loop through the results
while ($row = mysqli_fetch_assoc($result)) {
    // Process the retrieved data
}
