Kesalahan: "Sertifikat tidak dapat dijatuhkan karena satu atau lebih entitas ditandatangani atau dienkripsi menggunakannya."

Saya memiliki sertifikat yang ingin saya hapus dari database.

Jika saya mengeluarkan perintah

DROP CERTIFICATE <FooCert>

Saya mendapatkan kesalahan

The certificate cannot be dropped because one or more entities are either signed or encrypted using it

Menurut Jason Strate, saya harus bisa mengetahui apa yang ditandatangani oleh sertifikat.

Kueri berikut mengembalikan 0 baris:

SELECT OBJECT_SCHEMA_NAME(co.major_id) + '.' + OBJECT_NAME(co.major_id)
FROM sys.certificates c 
INNER JOIN sys.crypt_properties co ON c.thumbprint = co.thumbprint
WHERE co.crypt_type_desc = 'SIGNATURE BY CERTIFICATE' 
AND c.name = 'FooCert'

Saya juga mencoba memisahkan entitas per pertanyaan SO ini. /programming/52460/how-do-i-find-and-decouple-entities-from-a-certificate-when-upgrading-ms-sqlserv

Bagaimana saya bisa menghapus dependensi pada sertifikat ini sehingga saya bisa menghapusnya?

Untuk menemukan item yang terkait dengan Sertifikat dan Kunci Asimetris, pertama coba kueri yang diposting di DBA.SE ini.

Temukan prosedur, fungsi, pemicu, rakitan, dan yang ditandatangani sertifikat / kunci asimetris yang ditandatangani

Jika itu tidak mengembalikan objek apa pun, selanjutnya coba pertanyaan berikut yang mencari:

• Info masuk
• Pengguna
• Titik Akhir Pialang Layanan
• Endpoint Mirroring Basis Data
• Kunci Simetris
• Kunci Enkripsi Basis Data (digunakan untuk TDE)

Harap dicatat bahwa Login adalah tingkat Server / Instance sedangkan yang lainnya adalah tingkat Database. Selain itu, Kunci Enkripsi Basis Data, saat berada di level Basis Data, dilaporkan dalam DMV yang mengembalikan data untuk semua basis data, dan karenanya tidak berubah berdasarkan pada Basis Data "saat ini".

Mengalami masalah serupa, bagi saya kueri ini membantu saya menemukan objek yang ditandatangani:

SELECT OBJECT_SCHEMA_NAME(co.major_id) + '.' + OBJECT_NAME(co.major_id), c.name 
FROM sys.certificates c 
INNER JOIN sys.crypt_properties co ON c.thumbprint = co.thumbprint
WHERE co.crypt_type_desc = 'SIGNATURE BY CERTIFICATE'

Sumber

Kemudian saya hanya menggunakan perintah berikut sebagai contoh di mana dbo.sp_nameobjek yang ditandatangani dan STOREDPROCEDURESIGNINGCERTsertifikat penandatanganan.

DROP SIGNATURE FROM OBJECT::dbo.sp_name BY CERTIFICATE STOREDPROCEDURESIGNINGCERT
