DB2 FOR LUW / DB2FORLUW / B10 - DB2

When using string equality predicates containing strings that 
have differing code units (OCTETS, CODEUNITS16, CODEUNITS32), 
DB2 may return incorrect results. Keep in mind that the default 
code units used may differ depending on the current string_units 
and nchar_mapping database configuration parameters and the 
NLS_STRING_UNITS global variable. 
 
Example (with the default string_units database config parameter 
set to SYSTEM): 
 
CREATE TABLE T1 (a CHAR(2 CODEUNITS32) NOT NULL, b CHAR(5 
CODEUNITS32) NOT NULL) 
 
INSERT INTO T1 VALUES ('12', '345') 
 
SELECT a||b FROM T1 WHERE a='12' AND a||b LIKE '%12345%'

In the example above, either modify the string_units database 
config parameter to match the string constant's code units 
(OCTETS) with the column's (CODEUNITS32), or ensure each string 
reference in the equality expression uses the same code units by 
casting when needed: 
 
SELECT a||b FROM T1 WHERE CHAR(a)='12' AND a||b LIKE '%12345%'
