Filepath : ChiragStockproductModelResourceModelTestNewlistcollection.php

< ?php
namespace ChiragStockproductModelResourceModelTest;

class Newlistcollection extends MagentoFrameworkModelResourceModelDbCollectionAbstractCollection
{
    /**
     * Define model & resource model
     */
    protected function _construct()
    {
        $this->_init(
            'ChiragStockproductModelTest',
            'ChiragStockproductModelResourceModelTest'
        );
        /*public function update($argument)
        {
            $argument->addFieldToFilter('emailstatus',array('eq' => '1'));
            return $argument;
        }*/

    }
}
?>

This code give this result :

I want to display data with condition (emailstatus == 1) from my custom table. Here all data display and total row is 15. But there are 3 rows which has emailstatus =0. So I want to display 12 rows instead of 15. All 3 rows not display which has emailstatus=0.

If you want to more code, inform me. I will put it. Thanks in advance…
