Prototype (C/C++)

HRESULT Revoke(
SQLDMO_PRIVILEGE_TYPE iPrivileges, 
SQLDMO_LPCSTR RevokeeNames, 
BOOL GrantGrant, 
BOOL RevokeGrantOption, 
SQLDMO_LPCSTR AsRole);

Settings

Set Privileges by using these SQLDMO_PRIVILEGE_TYPE values. To specify more than a single permission, combine values by using an OR logical operator.

16

주의

When a user is a member of more than a single role, the user can have permission to grant access to a user-defined function under one role and not under another. In this case, SQL Server security mechanisms prevent execution of the Revoke method on the UserDefinedFunction object referencing that user-defined function. Use the AsRole argument to specify the role under which permission to execute the grant exists.

Granting permissions to database users and roles by using the Revoke method of the UserDefinedFunction object requires appropriate privilege. The SQL Server login used for SQLServer object connection must be granted the ability to execute GRANT referencing the user-defined function, the owner of the user-defined function, or a member of a role with greater privilege.

For more information about setting multistring parameters, see Using SQL-DMO Multistrings.

[!참고] If an application call the Revoke method of the UserDefinedFunction object on an instance of SQL Server version 7.0, NULL is returned.
