Re: Update query

UPDATE "MYLIB"/"F1TABLE"                                   
SET                                                          
      F1CODE  = (SELECT F2CODE                                 
                       FROM "MYLIB"/"F2TABLE"              
                       WHERE  (F1KEYFLD1  = F2KEYFLD1    AND   
                                      F1KEYFLD2  =  F2KEYFLD2))   
WHERE EXISTS                                                 
             (SELECT F2CODE
                       FROM "MYLIB"/"F2TABLE"              
                       WHERE  (F1KEYFLD1  = F2KEYFLD1    AND   
                                      F1KEYFLD2  =  F2KEYFLD2))   

note:  if you know you have every F1 record matching 
in the F2 file,  the "where" statement is not needed,
just let the 1=1 default take over, all you need is the update/set commands.
