DB2 FOR LUW / DB2FORLUW / 970 - DB2

When using a database created with NUMBER compatibility enabled, 
queries that use the distinct aggregation function AVG( DISTINCT 
column_or_expression ) may receive a SQL0901N error when the 
column or expression used in the function is typed as a user 
defined distinct type. 
 
For example 
 
create distinct type t_dec as decimal(10,3) with comparisons; 
create function avg(t_dec) returns t_dec source 
avg(decimal(10,3)); 
create table tbl1 (c1 integer, c2 t_dec); 
select avg(distinct c2) from tbl1 group by c1;

SQL0901N can be avoided by explicitly casting the column to the 
base type in the query. For example: 
select avg(distinct  DECIMAL(c2,10,3)) from tbl1 group by c1
