You have a few options, but the quickest is probably to just use a dummy value:

SQL

    SELECT chln_prefix,chln_no,chln_name
    FROM PC
EXCEPT
    SELECT prefix,doc_no, 0 AS DummyValue
    FROM PB

Oh, and the data type should probably match. looks like you are expecing a name, so instead of 0 you might want to use 'blah'.
