DB2 FOR LUW / DB2FORLUW / 970 - DB2

The problem can occur when all the following conditions are 
satisfied: 
 
1. DPF environment with table distributed across > 1 database 
partitions 
2. the query includes a predicate applied to the table access 
that indicates only a single database partition needs to be 
accessed, such as when the hash distribution key is bound to a 
constant value by means of an equality predicate or a predicate 
using the dbpartitionnum() function to filter rows only from a 
single database partition 
3. the query qualifies 0 rows from the table 
 
For example, if table T is hash distributed across multiple data 
partitions on column X, then the following query satisfies 
conditions 1 and 2: 
 
SELECT * 
FROM T 
WHERE X = 1 
 
If the table doesn't contain any rows matching "X=1", then 
condition 3 is satisfied and the section actuals information in 
the db2exfmt output will show "NA":
