Drodzy forumowicze, takie coś zwraca mi Doctrine profiler w aplikacji opartej na Zendzie:

[SQL] pobierz, plaintext 
   1. [26.87 ms] connect
   2. [0.15 ms] prepare
   3. [0.61 ms] SELECT b.id AS b__id, b.title AS b__title, c.id AS c__id, c.text AS c__text, c.user_id AS c__user_id, c.book_id AS c__book_id FROM book b LEFT JOIN comment c ON b.id = c.book_id WHERE (b.id = ?)
          * bindings: 1
   4. [0.13 ms] fetch
   5. [0.07 ms] fetch
   6. [0.06 ms] fetch
   7. [6.43 ms] SELECT c.id AS c__id, c.name AS c__name, COUNT(c2.book_id) AS c2__0 FROM category c LEFT JOIN category_book c2 ON c.id = c2.category_id GROUP BY c.id
[SQL] pobierz, plaintext 

Wytłumaczy mi kto co to są za zapytania fetch? Strona powinna mieć tylko 2 zapytania.

Poszukaj w google odnośnie "prepared statement" baz i poczytaj pdo prepared statement
