DB2 - Problem description

Problem IT19976 Status: Closed

SQL QUERIES WITH IN OR NOT IN CLAUSE MAY PRODUCE INCORRECT RESULTS FOR A
COLUMN-ORGANIZED TABLE

product:
DB2 FOR LUW / DB2FORLUW / B10 - DB2
Problem description:
Additional space is added in rewritten query to string predicate 
when we use "NOT IN" clause,  thus we get wrong results from 
query. 
This only happens when we have table organized by columns 
 
Example: 
     create table t(c varchar(5)) organize by column; 
     insert into t values('x'); 
 
     select substr(c,1) from t where substr(c,1) not in 
(CHAR('abc'),CHAR('x')); 
 
     1 
     ----- 
     x 
 
       1 record(s) selected. ==>incorrect result
