备注

The UserDefinedFunction object provides functionality that allows users to programmatically manage functions.

仅 Microsoft .NET Framework 的 2.0 版本支持此命名空间、类或成员。

To get UserDefinedFunction object properties, users can be a member of the public fixed server role.

To set UserDefinedFunction object properties, users must have ALTER permission on the user-defined function.

To create a user-defined function, users must have CREATE FUNCTION permission on the database and ALTER permission on the specified schema.

To drop a user-defined function, users must have CONTROL permission on the user-defined function and ALTER permission on the specified schema.

To grant, deny, or revoke permissions on the user-defined function to other users, users must have CONTROL permission on the user-defined function.
