Altering user-defined table types in SQL Server

Question

How can I alter a user-defined table type in SQL Server ?

Answer 1

As of my knowledge it is impossible to alter/modify a table type.You can create the type with a different name and then drop the old type and modify it to the new name

As per msdn, it is like 'The user-defined table type definition cannot be modified after it is created'.
