Please forgive help with this
If I have an instance with several tables and it is damaged, well and create another instance to be able to create a new database that I need and that I can not access by the damaged instance
as I try to restore a backup of the database that I need in the new instance but it marks me an error saying that this database already exists then my doubts would be:
1) the 2 instances are connected only in the databases (so if I do something in a database in the 2 instances affected)
2) but if I choose to delete one instance it does not affect the other or if
3) If you let me know it already exists, why can not I see the database in the new instance?
thanks
