MySql Query build using Kohana's ORM

Question

I'm having a hard time to translate the following query into kohana's ORM.

So, if I do the following works fine:

$query = DB::query(Database::SELECT, 'SELECT id_book, MATCH(title, author, isbn) AGAINST (:str) AS score FROM tab_books WHERE status = 1 AND MATCH(title, author, isbn) AGAINST (:str) HAVING score > '.$score.' ORDER BY score DESC LIMIT 100');

However, I need to use an specific class model. So far I have:

$books = new Model_Book();
$books = $books->where('status', '=', 1);
$books = $books->where(DB::expr('MATCH(`title`,`author`,`isbn`)'), 'AGAINST', DB::expr("(:str)"))->param(':str', $search_terms);

Which works fine, except for the fact that I'm unable to use the score value. I need the score because since I changed the table engine to InnoDB, the 2nd query is returning a lot of results.

Thank you for your time.

So, you don't use query builder , but ORM object finding . In first case you take result array on second array of objects.

Trust me, you don't want use list objects. (It's extremely slow)

$sq = DB::expr('MATCH(title, author, isbn) AGAINST (:str) AS score')
      ->param(":str", $search_terms);
$wq = DB::expr('MATCH(title, author, isbn)');
$query = DB::select('id_book', $sq)
  ->from('tab_books') // OR ->from($this->_table_name) for model method
    ->where('status','=',1) ->where($wq, 'AGAINST ', $search_terms)
  ->order_by('score', desc)->limit(100) //->offset(0)
  ->having('score', '>', $score);
$result = $query->execute()->as_array();

for query test:

die($query->compile(Database::instance()));

OT: Use

$books = ORM::factory('Book')->full_text($search_terms, $score);

instead $books = new Model_Book();
