Listed below. ON CERTIFICATE **::***certificate_name* Specifies the certificate on which the permission is being granted. The scope qualifier "::" is required. *database_principal* Specifies the principal to which the permission is being granted. One of the following: - database user - database role - application role - database user mapped to a Windows login - database user mapped to a Windows group - database user mapped to a certificate - database user mapped to an asymmetric key - database user not mapped to a server principal. GRANT OPTION Indicates that the principal will also be given the ability to grant the specified permission to other principals. AS *granting_principal* Specifies a principal from which the principal executing this query derives its right to grant the permission. One of the following: - database user - database role - application role - database user mapped to a Windows login - database user mapped to a Windows group - database user mapped to a certificate - database user mapped to an asymmetric key - database user not mapped to a server principal. ## Remarks A certificate is a database-level securable contained by the database that is its parent in the permissions hierarchy. The most specific and limited permissions that can be granted on a certificate are listed below, together with the more general permissions that include them by implication. |Certificate permission|Implied by certificate permission|Implied by database permission| |----------------------------|---------------------------------------|------------------------------------| |CONTROL|CONTROL|CONTROL| |TAKE OWNERSHIP|CONTROL|CONTROL| |ALTER|CONTROL|ALTER ANY CERTIFICATE| |REFERENCES|CONTROL|REFERENCES| |VIEW DEFINITION|CONTROL|VIEW DEFINITION| ## Permissions The grantor (or the principal specified with the AS option) must have either the permission itself with GRANT OPTION, or a higher permission that implies the permission being granted. If using the AS option, these additional requirements apply. |AS *granting_principal*|Additional permission required| |------------------------------|------------------------------------| |Database user|IMPERSONATE permission on the user, membership in the **db_securityadmin** fixed database role, membership in the **db_owner** fixed database role, or membership in the **sysadmin** fixed server role.| |Database user mapped to a Windows login|IMPERSONATE permission on the user, membership in the **db_securityadmin** fixed database role, membership in the **db_owner** fixed database role, or membership in the **sysadmin** fixed server role.| |Database user mapped to a Windows group|Membership in the Windows group, membership in the **db_securityadmin** fixed database role, membership in the **db_owner** fixed database role, or membership in the **sysadmin** fixed server role.| |Database user mapped to a certificate|Membership in the **db_securityadmin** fixed database role, membership in the **db_owner** fixed database role, or membership in the **sysadmin** fixed server role.| |Database user mapped to an asymmetric key|Membership in the **db_securityadmin** fixed database role, membership in the **db_owner** fixed database role, or membership in the **sysadmin** fixed server role.| |Database user not mapped to any server principal|IMPERSONATE permission on the user, membership in the **db_securityadmin** fixed database role, membership in the **db_owner** fixed database role, or membership in the **sysadmin** fixed server role.| |Database role|ALTER permission on the role, membership in the **db_securityadmin** fixed database role, membership in the **db_owner** fixed database role, or membership in the **sysadmin** fixed server role.| |Application role|ALTER permission on the role, membership in the **db_securityadmin** fixed database role, membership in the **db_owner** fixed database role, or membership in the **sysadmin** fixed server role.| Object owners can grant permissions on the objects they own. Principals with CONTROL permission on a securable can grant permission on that securable. Grantees of CONTROL SERVER permission, such as members of the **sysadmin** fixed server role, can grant any permission on any securable in the server. Grantees of CONTROL permission on a database, such as members of the **db_owner** fixed database role, can grant any permission on any securable in the database. Grantees of CONTROL permission on a schema can grant any permission on any object within the schema. ## See Also [GRANT (Transact-SQL)](../../t-sql/statements/grant-transact-sql.md) [Permissions (Database Engine)](../../relational-databases/security/permissions-database-engine.md) [Principals (Database Engine)](../../relational-databases/security/authentication-access/principals-database-engine.md) [CREATE CERTIFICATE (Transact-SQL)](../../t-sql/statements/create-certificate-transact-sql.md) [CREATE ASYMMETRIC KEY (Transact-SQL)](../../t-sql/statements/create-asymmetric-key-transact-sql.md) [CREATE APPLICATION ROLE (Transact-SQL)](../../t-sql/statements/create-application-role-transact-sql.md) [Encryption Hierarchy](../../relational-databases/security/encryption/encryption-hierarchy.md)
