RE: SQL UPDATE of SELECTed records

Steve,

You're example code isn't enough.  As other have mentioned the where clause 
doesn't make sense.

This would work fine:

UPDATE library/filea A
SET field1 = 'U'
WHERE
a.field2 in (SELECT B.field1
             FROM library/fileb B
             WHERE conditions)

or for instance (one I just did yesterday),

update mpwipimay2 A                        
set(A.WIIINA, A.WIIOTA, A.WIIYRI, A.WIIYRO) =  ( select  B.WIIINA,    
                                                         B.WIIOTA,
                                                         B.WIIYRI,
                                                         B.WIIYRO 
                                                 from mpwipimay1 B  
                                                 where A.WIIPRT = B.WIIPRT  
                                                   and A.WIICLS = B.WIICLS)

HTH,
