how to delete database(entity) records? I want to use same application as fresh database??

In my application I was deleted all records, but I created auto generated number in entity. Now I want to remove all existing records in database(using mendix database only)

Deleting the records from the database using retrieve all + Delete activity will only delete the records

It won't reset the auto number. This will carry on with counting from the last generated number
