zend framework 查询遇到点小问题,谢谢大神们
$tableUsers_1 = Engine_Api::_()->getDbtable('users', 'user');
$select_companies = $tableUsers_1->select();
$select_companies->where('`'.$table->info('name').'`.`level_id` = ?', 6);  

这样是查询满足level_id=6的条件是吧,那么我想查询既满足level_id=6又满足enabled=1,查询语句该怎么写呢,这两个条件都在这一个表中。还有  where('`'.$table   中的 '`' 是什么意思! 
------解决方案--------------------
$select_companies->where('`'.$table->info('name').'`.`level_id` = ? and `enabled `=1', 6);  

where('`'.$table   中的 '`' 是字符串拼接,`是用來轉義表名,字段名的,因為如果你表名是index(index 是sql關鍵字),直接寫select * from index 會錯,需要寫成 select * from `index`
