Обсуждение: SQL syntax for updating tables

I'm trying to figure this out and I'm stumped. Perhaps someone else has 
done it.

I have two tables:
SIGMEMBER
and
MEMBER

The MEMBER table has a USERID field and an EMAIL field. SIGMEMBER has the 
same two fields. I am trying to update SIGMEMBER from MEMBER such that when 
member.userid = sigmember.userid, it replaces sigmember.email with 
member.email.

Any suggestions?

UPDATE sigmember SET sigmember.email=member.email WHERE
sigmember.userid=member.userid;

should work.
