For example, if you want to update a table called 'node__field_graduate_title' and remove the html:

$connection = \Drupal\Core\Database\Database::getConnection();

	$results = $connection->query('select bundle, entity_id, revision_id, field_graduate_title_value from node__field_graduate_title;')->fetchAll();

	if ($results) {    
		foreach ($results as $record) {

			$graduate_title = strip_tags($record->field_graduate_title_value);
			$connection->update('node__field_graduate_title')
				->fields(array(
					'field_graduate_title_value' => $graduate_title,
					))
				->condition('bundle', $record->bundle, '=')
				->condition('revision_id', $record->revision_id, '=')
				->condition('entity_id', $record->entity_id, '=')
				->execute();  
		}  
	}
