How to update all tables in a database comparing with another database? : <p>I have a database of more than 500 tables and now there is a copy of that database from an old backup.We noticed that there are many missing records in the new database which I would like to update from the old? </p>

<p>Whats the best practice to update all the records from another database, We can do it individually using queries but it's time-consuming and we have a deadline. Is there any alternative or best way to accomplish this. </p>

<p>Regards</p>
