Is it necessary to update all fields in a database record when using the UPDATE statement in MySQL through PHP?

When using the UPDATE statement in MySQL through PHP, it is not necessary to update all fields in a database record. You can selectively update specific fields by specifying them in the SET clause of the UPDATE statement. 

<?php

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";
$conn = new mysqli($servername, $username, $password, $dbname);

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

// Update specific fields in a database record
$sql = "UPDATE table_name SET field1 = 'new_value1', field2 = 'new_value2' WHERE id = 1";

if ($conn->query($sql) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $conn->error;
}

$conn->close();

?>
