IT00929: COLLATION_KEY_BIT MIGHT GENERATE EMPTY STRINGS IN ORACLE MODE IF INPUT STRING CONSISTS OF BLANKS

DB2 Version 10.1 Fix Pack 4 for Linux, UNIX, and Windows
DB2 Version 10.1 Fix Pack 6 for Linux, UNIX, and Windows

APAR status

• Closed as program error.

Error description

• The COLLATION_KEY_BIT function might generate empty strings
  while running in Oracle mode if the input string consists of
  nothing but one or more blank characters. In Oracle there is no
  concept of an empty string. Instead of an empty string,
  the COLLATION_KEY_BIT function should return NULL.
  

Local fix

• Avoid using the COLLATION_KEY_BIT function on blank input
  strings while running in Oracle mode.
