DB2 FOR LUW / DB2FORLUW / A10 - DB2

Fetch first n row clause in a federated query is pushed down. 
This behaviour leads to incorrect results. 
 
Example query: 
 
select * from 
    ( 
        select tab1.col1, tab2.col1 as vcol1 
        from abc123a.tab1 tab1 
        join schema1.tab2 tab2 
        ON tab2.col1 = tab1.col1 
    ) as result1 
    fetch first 5 row only; 
 
where abc123a.tab1 is a nickname 
 
will return incorrect results because 'fetch first 5 row only' 
is pushed down.
