DB2 FOR LUW / DB2FORLUW / A50 - DB2

An incorrect result set might be produced when INTRA_PARALLEL is 
enabled for a SQL statement if all of the following conditions 
are met: 
(a) the statement contains an IN predicate referencing a numeric 
column type that is not an integer 
(b) the values list of the IN predicate contains integer values 
(c) the optimizer produces an access plan with a MSJOIN to apply 
the IN predicate as a join 
(d) the query degree of the access plan is > 1 
 
For example, if the column DECCOL is of type decimal, then the 
following IN predicate satisfies conditions (a) and (b): 
DECCOL IN (1,2,3) 
 
You can collect an EXPLAIN of the statement to confirm if a 
MSJOIN operation is performed and the query degree of the access 
plan is a value > 1.

You can attempt to avoid the MSJOIN operation by using an 
optimization guideline to request a different join alternative, 
such as NLJOIN or HSJOIN.

The problem is first fixed in DB2 version 10.5.0.5.
