Tabletype as framework for new tables

Question

I am playing with tabletypes and it seems you can only use this for passing tabledata to a stored procedure. It would be nice if a tabletype can be used as a template for tables like:

CREATE TYPE [EnumList] 
AS TABLE (
         ID int identity(1,1) PRIMARY KEY,
         Value varchar(32) NOT NULL UNIQUE,
         IsActive bit NOT NULL DEFAULT(1),
         CreatedBy sysname NOT NULL default SUSER_NAME(),
         CreatedDate smalldatetime NOT NULL default CURRENT_TIMESTAMP
       )
GO

create table enum_valuta as EnumList -- not working
GO

However this gives an error. Am I missing something? If this would work, SQL will become a little more object-oriented :)

You can use the type to declare a table variable though. And then use that to make a table using SELECT INTO...

CREATE TYPE [EnumList] 
AS TABLE (
         ID int identity(1,1) PRIMARY KEY,
         Value varchar(32) NOT NULL UNIQUE,
         IsActive bit NOT NULL DEFAULT(1),
         CreatedBy sysname NOT NULL default SUSER_NAME(),
         CreatedDate smalldatetime NOT NULL default CURRENT_TIMESTAMP
       )
GO

declare @enum_valuta as EnumList

insert into @enum_valuta (Value, IsActive) select 'aaaa',1
insert into @enum_valuta (Value, IsActive) select 'bbbb',1
insert into @enum_valuta (Value, IsActive) select 'cccc',0

select * into Enum_valuta from @enum_valuta

select * from Enum_valuta

drop type [EnumList]
drop table Enum_valuta

Yes, I know, but this is for in memory operations. What confuses me is that this statement is working:

create type SSN_type from varchar(11) go create table person(name varchar(32), SSN SSN_type) go

While my previous example is not working
