kohana直接执行query写法sql语句

// Create a new SELECT query $query =DB::query(Database::SELECT, 'SELECT * FROM users' );   // Create a new DELETE query $query =DB::query(Database:: DELETE , 'DELETE FROM users WHERE id =5' ); // Create a new UPDATE query $query =DB::query(Database:: DELETE , 'UPDATE users SET title=3 WHERE id =5' );

最后要加上执行语句：

$result = $query ->execute();

$query =DB::insert('users',array('username','password'))->values(array('fred','p@5sW0Rd'));INSERT INTO `users` (`username`,`password`) VALUES ('fred','p@5sW0Rd')$query =DB::update('users')->set(array('username' => 'jane'))->where('username','=','john');UPDATE `users` SET `username` ='jane' WHERE `username` ='john'$fields =array('cityname','pinyin','py','p');$query =DB::insert('city',$fields);foreach($data as $k=>$v){$query->values($v);}$query->execute();echo $query;return $query;$result为受影响的数据库记录数。http://www.kofans.org/3.2/guide/database/query/builder#insert
