findFirst conditions with trim function

Hi, i have a problem with phalcon.

Product::findFirst([ 'conditions' => "trim(trailing '/' from url) LIKE :url:", 'bind' => ['url' => '%xxx%'] ]);

and i get

PHP Fatal error: Uncaught Phalcon\Mvc\Model\Exception: Syntax error, unexpected token STRING(/), near to ' from url) LIKE :url: LIMIT :APL0:', when parsing: SELECT [App\Models\Product].* FROM [App\Models\Product] WHERE trim(trailing '/' from url) LIKE :url: LIMIT :APL0: (115) in

That trim syntax is only valid for MySQL, and Phalcon has it's own query abstraction layer (PHQL). Afaik, PHQL implementation only accepts one parameter and trims both leading and trailing characters. The reason for this is to abstract away the DB specific engine.

You should create a dialect class and implement your own trim function (with a different name). Here is a REGEXP example:

As @Lajos said, it's MySQL only feature.

Here is how you can achieve it with raw queries:

$sql = "SELECT * FROM `admin_users` WHERE TRIM(TRAILING '3' FROM username) LIKE :username LIMIT 1";
$params = [
    'username' => '%niki%'
$model = new \Models\AdminUsers();
$test = new \Phalcon\Mvc\Model\Resultset\Simple(
    $model->getReadConnection()->query($sql, $params)

// Result
    [0] => Array
            [id] => 1
            [type] => developer
            [names] => Niki Mihaylov
            [username] => niki
            [password] => $2y$08$WVZIc1U0L1Ezd1BpSytXLucfBK0XWbXXNXd6Zs6m9bo15i/22Hi7m
            [settings] => {"interfaceLanguage":"bg"}
            [last_activity] => 2016-07-18 13:15:57
