If you mean SQL Server table variables, it's just like a normal table:

DECLARE @Foo TABLE
(
  foo int
);

insert into @Foo values (1);
insert into @Foo values (1);
insert into @Foo values (1);
insert into @Foo values (1);

select COUNT(*) from @Foo;

SELECT COUNT(*) OVER ( ) AS 'RowCount' FROM @yourTableVariable

works perfect for table variables!

SELECT COUNT(*) FROM TABLE_NAME;
