You can drop multiple database in a single command. The syntax is

Create two databases Sales & Purchase as shown below

You can drop both of them using

Drop Database if Exists

IF EXISTS Applies to: SQL Server 2016 and above

If you try to delete a non-existent database, you will see the following error message. For Example, run the command drop database hr and you will see the following error message

Cannot drop the database 'HR', because it does not exist or you do not have permission.

You can use the IF EXISTS Clause, which will not raise the error. For example, the following query will drop the database HR, only if exists else it does nothing

The database cannot be removed if in use

We cannot delete the database, which is in use. This means some user is reading or writing to the database.

For Example run the following query

The above example is a simple use case. You can run the use master to use the master database, which stops using the sales database. And then drop the sales database as shown below

But if you forcefully remove all the users, who are using the database using the command. SET SINGLE_USER forces the database be work in Single User mode. It logs out all other users. Now you can safely drop the database.
