Removes a certificate from the database.
Important
A backup of the certificate used for database encryption should be retained even if the encryption is no longer enabled on a database. Even though the database is not encrypted anymore, parts of the transaction log may still remain protected, and the certificate may be needed for some operations until the full backup of the database is performed. The certificate is also needed to be able to restore from the backups created at the time the database was encrypted.
Transact-SQL Syntax Conventions
DROP CERTIFICATE certificate_name
certificate_name
Is the unique name by which the certificate is known in the database.
Certificates can only be dropped if no entities are associated with them.
Requires CONTROL permission on the certificate.
