DB2 FOR LUW / DB2FORLUW / 970 - DB2

A SQL query involving nicknames and IN predicate can return 
incorrect result. The number of returned rows can be less than 
the correct number. The query should meet the following 
conditions: 
 
1) The query has nickname involved. 
2) It has IN predicate, which is internally transformed to a 
join. 
3) The data source of nickname is not Oracle or Sybase. 
 
Example: 
SELECT n.col1, n.col2, n.col3, n.col4, n.col5 
FROM USER.NICK n 
WHERE n.col1 in (select col1 from table(values ('abcd') 
,('efgh')) as q1(col1)) 
order by 3;
