Question

I started using Zend_Paginator,
it works everything fine but I noticed that there is one more query which slows the load time down.
The additional query:

SELECT COUNT(1) AS `zend_paginator_row_count` FROM `content`

The normal query:

SELECT `content`.`id`, `content`.`name` FROM `content` LIMIT 2

PHP:

$adapter = new Zend_Paginator_Adapter_DbSelect($table->select()->from($table, array('id', 'name')));
$paginator = new Zend_Paginator($adapter);

Could I merge the two querys into one (for better performance)?

Answer 1

Merging the two wouldn’t really have much of a performance increase if any. The actual select content has the limit statement in it (as you are trying to get a subset of the entire table in the database) where the count needs to count all rows in the database. The reason it is done like this is to prevent having to select a very large set of data simply to get the count.
