What are the potential pitfalls of storing both first and last names in a single column in a database?

Storing both first and last names in a single column in a database can make it difficult to retrieve and manipulate the data separately. It can also lead to issues with sorting, searching, and displaying the names correctly. To solve this issue, it is recommended to store first and last names in separate columns in the database. 

// Example of storing first and last names in separate columns in a MySQL database

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

$conn = new mysqli($servername, $username, $password, $dbname);

// Create a table with separate columns for first and last names
$sql = "CREATE TABLE Persons (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    first_name VARCHAR(30) NOT NULL,
    last_name VARCHAR(30) NOT NULL
)";

if ($conn->query($sql) === TRUE) {
    echo "Table Persons created successfully";
} else {
    echo "Error creating table: " . $conn->error;
}

// Close the connection
$conn->close();
