Magento 2: Filter Field with Date Issue

Question

I have below code

$updatedAtFrom = date("Y-m-d",strtotime($updatedAt['orig_from']));
$updatedAtTo = date("Y-m-d",strtotime($updatedAt['orig_to']));
$this->getCollection()->addFieldToFilter('DATE(main_table.updated_at)', array('from' => $updatedAtFrom,'to' => $updatedAtTo));

When I run query it displays

(`DATE(main_table`.`updated_at)` >= '2017-04-17' AND `DATE(main_table`.`updated_at)` <= '2017-04-17')

So it gives #1054 - Unknown column 'DATE(main_table.updated_at)' in 'where clause'

When I remove DATE then it works fine. I have that field as type timestamp. But I want to compare only Date.

You can try with Zend_Db_Expr.

$queryExpr = new \Zend_Db_Expr("DATE(main_table.updated_at) >= '{$updatedAtFrom}' AND DATE(main_table.updated_at) <= '{$updatedAtTo}'");

$this->getCollection()->getSelect()->where($queryExpr);

Answer 2

You need to format date in Y-m-d H:i:s format. Then use collection filter as follows.

$this->getCollection()->addFieldToFilter('updated_at', ['lteq' => $datetime->format('Y-m-d H:i:s')])
    ->addFieldToFilter('updated_at', ['gteq' => $datetime->format('Y-m-d H:i:s')]);

Where $datetime is object of DateTime.

You can try with Zend_Db_Expr.

$updatedAtFrom = date("Y-m-d",strtotime($updatedAt['orig_from']));
$updatedAtTo = date("Y-m-d",strtotime($updatedAt['orig_to']));
$this->getCollection()->addFieldToFilter(new \Zend_Db_Expr("DATE(main_table.updated_at)"), array('from' => $updatedAtFrom,'to' => $updatedAtTo));
