I know I can return an empty table using the following query :
select * from tbFoo where 1=2
but that code doesn't look nice to me.
Is there a 'standard' way of doing this?
If you're wondering why I want to do such a strange thing, it's because I can't name the datatables I return from a stored procedure, so I need empty placeholders.

The TRUNCATE TABLE statement in SQL is a Data Definition Language (DDL) operation that labels a table's extents for DE allocation (empty for reuse). This procedure removes all data from a table easily, usually bypassing a variety of integrity checking mechanisms.
There are two ways to replace NULL with blank values in SQL Server, function ISNULL(), and COALESCE(). Both functions replace the value you provide when the argument is NULL like ISNULL(column, '') will return empty String if the column value is NULL.
Having just run both:
SELECT TOP 0 * FROM Table
and
SELECT * FROM Table WHERE 1=0
They produce exactly the same execution plan.
