sql server - Is there anyway to reset the identity of a Table Variable?

Question

Say I have a table variable:

DECLARE @MyTableVar TABLE (ID INT IDENTITY(1,1), SomeData NVARCHAR(300))

After I have inserted 250 rows, I need to "Start Over" with the table. I do this:

DELETE FROM @MyTableVar

Is there anything I can do to the table variable so that this:

insert into @MyTableVar Values("TestData")
select * from @MyTableVar

will return this:

_______________________________
|    ID     |    SomeData     |
|___________|_________________|
|           |                 |   
|     1     |    TestData     |        
|___________|_________________|

instead of this:

_______________________________
|    ID     |    SomeData     |
|___________|_________________|
|           |                 |   
|    251    |    TestData     |        
|___________|_________________|

Answer 1

Instead relying on an Identity, why not use the new ranking functions such as Row_Number

Insert @MyTableVar( Id, Value )
Select Row_Number() Over ( Order By Value )
    , Value
From SomeOtherTable
