DB2 FOR LUW / DB2FORLUW / 970 - DB2

In a VARCHAR2 enabled database, an assignment of an empty string 
value to a CHAR, VARCHAR, GRAPHIC or VARGRAPHIC should produce a 
NULL value.  However, if a string literal is not empty, consists 
of all blanks is passed as an argument to the scalar functions 
CHAR, VARCHAR, GRAPHIC or VARGRAPHIC, and has a specified length 
of 0, then an empty string is returned instead of the expected 
NULL.  The returned string might look like the following sample: 
 
values char('   ',0) 
 
1 
- 
 
 
  1 record(s) selected.

Change the string literal to an empty string.  For example, 
changing the string literal to CHAR('',0) will fix this issue.
