How can the use of primary keys in MySQL tables impact the ability to update records in a sortable interface created with jQuery in PHP?

When using primary keys in MySQL tables, it is important to ensure that they are properly indexed for efficient updates in a sortable interface created with jQuery in PHP. Without properly indexed primary keys, updating records in a sortable interface can be slow and inefficient. To solve this issue, make sure to include the primary key in the WHERE clause of the SQL update statement to target the specific record that needs to be updated. 

// Assuming $primaryKey is the primary key value of the record to be updated
// Assuming $newData is an array containing the updated data

// Connect to the database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Update query with properly indexed primary key in the WHERE clause
$query = "UPDATE table_name SET column1 = '{$newData['column1']}', column2 = '{$newData['column2']}' WHERE primary_key_column = '{$primaryKey}'";

// Execute the query
mysqli_query($connection, $query);

// Close the database connection
mysqli_close($connection);
