#6041: Model->find "NOT" does not work as expected ---------------------------+------------------------------------------------ Reporter: datac0re | Owner: Type: Bug | Status: new Priority: Medium | Milestone: 1.2.x.x Component: Model | Version: 1.2 Final Severity: Normal | Resolution: Keywords: Model NOT | Php_version: PHP 5 Cake_version: 1.2.0.7962 | ---------------------------+------------------------------------------------ Comment (by datac0re):
(I apologize if this double posts, but the formatting of the original ticket messes up what I'm trying to say) In 1.2.0.7962 when crafting the following conditions, the generated SQL does not match with what I would expect. Maybe this is a bug, maybe it's by design, but if it is by design, I feel that the behavior is counter- intuitive and may cause people to not get what they are looking for (it happened to me!). Example: {{{ $model->find('all', array( 'conditions' => array( 'id >' => 25 'NOT' => array( 'src' => '', 'lastapp' => 'MeetMe' ) ) )); }}} I would expect the SQL to generate the following: {{{ 1. WHERE id > 25 AND NOT (src = '' and lastapp = 'MeetMe') }}} instead, this is what is generated: {{{ 2. WHERE id > 25 AND (NOT (`src` = '') AND NOT (`lastapp` = 'MeetMe')) }}} The two statements are NOT equal (i.e. the NOT operator isn't distributive) See the following tests: {{{ Ex 1: src = '' lastapp = 'MeetMe' Query 1: NOT (TRUE and TRUE) = FALSE Query 2: NOT (TRUE) and NOT (TRUE) = FALSE Ex 2: src = 'anything' lastapp = 'MeetMe' Query 1: NOT (FALSE AND TRUE) = TRUE Query 2: NOT (FALSE) and NOT (TRUE) = FALSE Ex 3: src = '' lastapp = 'anything' Query 1: NOT (TRUE AND FALSE) = TRUE Query 2: NOT (TRUE) and NOT (FALSE) = FALSE Ex 4: src = 'anything' lastapp = 'anything Query 1: NOT (FALSE AND FALSE) = TRUE Query 2: NOT (FALSE) and NOT (FALSE) = TRUE }}} Example 2 and 4 show that the statements are not equal. I've verified it by also doing both versions of the queries and getting counts back that differ. -- Ticket URL: <https://trac.cakephp.org/ticket/6041#comment:1> CakePHP : The Rapid Development Framework for PHP <https://trac.cakephp.org/> Cake is a rapid development framework for PHP which uses commonly known design patterns like ActiveRecord, Association Data Mapping, Front Controller and MVC.
