Phalcon datetime in model query error - php

Question

I am trying to execute a query like this:
Select * from table where created_at > DATE_SUB(NOW(), INTERVAL 1 DAY) in phalcon model query form. But i keep getting the following error:
Syntax error, unexpected token INTEGER(1), near to ' DAY)',
By query building is like below
$donations = Donations::query()
->where('created_at > DATE_SUB(NOW(), INTERVAL 1 DAY)')
->execute();
The above code gives me that error. Now i have tried like below
$donations = Donations::query()
->where('created_at > :holder:')
->bind(["holder" => 'DATE_SUB(NOW(), INTERVAL 1 DAY)'])
->execute();
Although this binding does not give me an error, it gives me a 0 result but i have a few rows inserted into the table to check this and when i execute the query in phpmyadmin it works correctly, So i assumed there might be a datetime mix up in the phalcon library setup of mine but when i changed from 1 DAY to 1 MONTH there is still not result. Can someone guide me on this.

Answer 1

INTERVAL, DATE_SUB, NOW() and other similar are MySQL only features and are not supported by PHQL.
You have two options:
1) Rewrite your WHERE condition by using PHP date:
$date = date('Y-m-d', strtotime('-1 DAY')); // Modify according to your date format
$donations = Donations::query()
->where('created_at > :holder:')
->bind(["holder" => $date)
->execute();
2) Extend MySQL with a dialect class:
$di->set('db', function() use ($config) {
return new \Phalcon\Db\Adapter\Pdo\Mysql(array(
"host" => $config->database->host,
"username" => $config->database->username,
"password" => $config->database->password,
"dbname" => $config->database->name,
"dialectClass" => '\Phalcon\Db\Dialect\MysqlExtended'
));
});
