I am using Magento 2.2.6 version. Am just trying to add an extra column updated_at in setup/upgradeschema.php. But on saving data, it is not updating the timestamp automatically. It is null always. Here is my code,
$installer->getConnection()->addColumn( 'updated_at', \Magento\Framework\DB\Ddl\Table::TYPE_TIMESTAMP, null, ['nullable' => false, 'default' => \Magento\Framework\DB\Ddl\Table::TIMESTAMP_INIT_UPDATE], 'Updated At' );
Adding the above code in
in upgradeschema[But only on creating the whole new table]
works fine. Can someone help?
