Have you declared your table variables? Assuming you have you still
need to use an alias. Variable names aren't valid as aliases:

DECLARE @a TABLE (someid INT, stuff INT);
DECLARE @b TABLE (someid INT, otherstuff INT);

UPDATE A
SET stuff =
(SELECT B.otherstuff
FROM @b AS B
WHERE B.someID = A.someID)
FROM @a AS A ;

Whenever possible please post enough code to reproduce your problem.
Including CREATE TABLE and INSERT statements usually helps.
State what version of SQL Server you are using and specify the content
of any error messages.
