DB2 FOR LUW / DB2FORLUW / A10 - DB2

DB2 might produce SQL0901N when the following conditions are 
true: 
1. There is a NOT IN subquery 
2. The NOT IN subquery contains one or more scalar subqueries 
which have correlation 
3. The parent of the NOT IN subquery, i.e. the column on which 
NOT IN predicate is applied is nullable 
4. There is another table in the query which is joined to the 
parent table 
 
eg. 
create table X(col1 int, col2 int); <--------- condition 3 
 
SELECT 
col1 
FROM 
X,  <-------------- parent table 
Y   <-------------- condition 4 
WHERE 
X.col1 = Y.col1 AND 
X.col1 NOT IN (         <----------------- condition 1 
        SELECT 
        col1 
        FROM 
        A, D 
        WHERE 
        A.col2 = D.col2 AND 
        A.col3 = D.col3 AND 
        D.col4 = (  SELECT   <----------------- condition 2 
                         MAX(col4) 
                         FROM  E 
                         WHERE 
                         E.col2 = D.col2  ) 
        );
