Remarks

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

This namespace, class, or member is supported only in version 2.0 of the Microsoft .NET Framework.

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.
