    By increment +1 into last inserted id you may get your new ID – Ronak Chauhan May 18 '17 at 7:25

As per as your comment, you want validate customer mobile no before have whenever new customer is created or record is updated.

In this you can use your customer_save_before event:

and observer may be like this:


<?php
namespace Devamitbera\MobileCheck\Observer;

use Magento\Framework\Event\ObserverInterface;
use Magento\Framework\App\Request\DataPersistorInterface;
use Magento\Framework\App\ObjectManager;
use Magento\Framework\Exception\AlreadyExistsException;

class ValidateMobileNo implements ObserverInterface
{

    protected $_customerCollectionFactory;
    public function __construct(
        \Magento\Customer\Model\ResourceModel\Customer\CollectionFactory $customerCollectionFactory,
    ) {
        $this->_customerCollectionFactory = $customerCollectionFactory;
    }


    /**
     *
     * @param \Magento\Framework\Event\Observer $observer
     * @return void
     */
    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        $customer = $observer->getCustomer();
        $customerCollection= $this->_customerCollectionFactory->create();
        $customerCollection->addAttribuTeToFilter('[YOUR_ATTRUBUTE]',$customer->getData('[YOUR_ATTRUBUTE]'));
        if ($customer->getId()) {   
            $customerCollection->addAttribuTeToFilter('entity_id',array('neq' => (int)$customer->getId()));   
         }   
         if($customerCollection->getSize()>0){
             throw new AlreadyExistsException(
                __('A customer with the same Mobile already exists .')
            );

         }

    }

}

I have not tried it myself but dig into Magento core files and got this solution.

Please look into this class:

Magento\Framework\Model\ResourceModel\Db\AbstractDb

Into the function named saveNewObject() around line number 762

 $object->setId($this->getConnection()->lastInsertId($this->getMainTable()));

using the lastInsertId() one can get the last added Id in particular table by passing the name of the table.

Hope, this will help you.
