DB2 FOR LUW / DB2FORLUW / 970 - DB2

When you use SET SESSION AUTHORIZATION or SET SESSION_USER with 
a 
string constant inside of an SQL routine, compiling the routine 
will cause your instance to terminate abnormally. 
 
For example: 
 
CREATE PROCEDURE SP_TEST 
LANGUAGE SQL 
BEGIN 
  SET SESSION_USER = 'UNIUSR';  -- will cause a trap when 
compiled 
END 
 
CREATE PROCEDURE SP_TEST 
LANGUAGE SQL 
BEGIN 
  SET SESSION_USER = UNIUSR; -- will compile successfully 
END
