What is the significance of using DATE and DATETIME formats in MySQL for storing date values?

Using DATE and DATETIME formats in MySQL for storing date values is significant because it allows for efficient storage and retrieval of date and time information. DATE format stores only the date without the time, while DATETIME format stores both the date and time. Choosing the appropriate format based on the requirements of the application helps in optimizing storage space and query performance. 

// Example of creating a table with DATE and DATETIME columns in MySQL
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

// Check connection
if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}

// Create table
$sql = "CREATE TABLE MyDates (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    date_only DATE,
    date_time DATETIME
)";

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

$conn->close();
