DB2 FOR LUW / DB2FORLUW / B10 - DB2

When the input parameters of an inlined SQL scalar UDF contains 
an OLAP specification, and under any of the following 
situations, wrong results are possible. 
 
(1) When such UDF appears in select clause, and the select 
clause also has "distinct" keyword. 
(2) When such UDF appears in order by clause 
 
You can work around the issue by modifying the query. For 
example, if the query is: 
 
select C2 
from T1 
order by F1(min(C1) over (partition by C2)) 
 
You can modify the query to: 
 
select C2 
from 
( 
select C2, F1(min(C1) over (partition by C2)) as CC 
from T1 
) 
order by CC 
 
If the query is 
 
select distinct F1(min(C1) over (partition by c2)) * 
F1(count(C1) over (partition by c2)) 
from T1 
 
You can modify the query to: 
 
select distinct F1(CC1) * F1(CC2) 
from 
( 
select min(C1) over (partition by c2) as CC1, count(C1) over 
(partition by c2) as CC2 
from T1 
)
