+### Query Keywords
+To add LOW PRIORITY | DELAYED | HIGH PRIORITY | IGNORE and the rest of mysql keywords to INSERT , SELECT , UPDATE, DELETE query:
+```php
+$db->setQueryOption('LOW_PRIORITY');
+$db->insert($table,$param);
+// GIVES: INSERT LOW_PRIORITY INTO table ...

+Also you can use an array of keywords:

+// GIVES: INSERT LOW_PRIORITY IGNORE INTO table ...
