> In the page, I found next example.
> -- Introduce a way of "generating" new data values,
> -- using a query which selects from a VALUES clause (which is an
> -- alternate form of a fullselect).
> -- This query shows how a table can be derived called "X" having
> -- 2 columns "R1" and "R2" and 1 row of data.
> SELECT R1,R2
> FROM (VALUES('GROUP 1','GROUP 2')) AS X(R1,R2)
> I think this is not ScalarSubquery because the result have two columns.
