How to check if a Credential exists in a SQL Server instance?

Question

How can you check if a Credential already exists in a SQL Server instance, so as to avoid an error when running a DROP CREDENTIAL ?

Normally I use the SCRIPT AS ... and DROP And CREATE To feature in SSMS to create the script, but the CREDENTIAL doesn't have that option

Answer 1

if exists (select * from sys.credentials where name = 'CredName')
    drop credential CredName
