Synopsis

Drop database user

Description

If user is the owner of a schema with the same name and if if the schema does not have any underlying objects the schema will be
dropped. If user owns more than one schema, the owner of the schemas that does not have the same name as the user, will be
changed to 'dbo'. If schemas have underlying objects, you must specify the -Force parameter so the user can be dropped.

-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
