On the typeof() campaign trail

Given a table:

CREATE TABLE [person] (
[id] INT IDENTITY(1,1) ,
[name] VARCHAR(100) ,
[age] INT

How nice would it be to be able to do something like this inside your stored procedures?:

[name] typeof([person].[name]) ,
[age] typeof([person].[age])

Or, perhaps, declare something to be of type:

CREATE TYPE [dbo].[person] AS TABLE (
[name]  typeof([person].[name]) ,
[age]   typeof([person].[age])

Maybe you could even wrap it all up as:

CREATE PROC InsertPeople
@person [dbo].[person] READONLY
SELECT  [name],[age]
FROM    @person;

You know what to do.

That is all!

Great idea! Reminds me when I encountered an issue where parameters ranging from varchar(10) to varchar(100) to char(10) (just to mention a few) were used in stored procs referencing a table column of char(2). I had to change several procs to use char(2) parameter. One more vote!
