How do I alter this SQL, so that the original field remains the same when
there is no match? A case when else end should do it, but I can't get it
right.
UPDATE Table1 SET Field1 =
(SELECT Field2 FROM Table2
WHERE Table1.Field1 = Table2.Field1)
Thanks for any advice.

At the end (outside the subquery), add:
WHERE Field1 IN (SELECT Field1 FROM Table2)
