DB2 FOR LUW / DB2FORLUW / 970 - DB2

Under some collating sequences, a query can return incorrect 
results or a SQL0901 error code when a FOR BIT DATA argument is 
passed to a SQL user-defined function expecting mixed data input 
parameters and that parameter is used by a LIKE, LOCATE, 
LOCATE_IN_STRING, INSTR, POSSTR or POSITION built-in function. 
 
The following example should return 'T' but will return 'F' if 
you are using an affected collation prior to the fixpak 
containing the fix. 
 
CREATE FUNCTION F(x varchar(10)) RETURNS varchar(1) 
  deterministic no external action reads sql data 
  return case when x like '%def' then 'T' else 'F' end; 
 
VALUES F( cast( 'abcdef' as varchar(10) for bit data ) );

Cast the function input to MIXED DATA prior to passing it as 
input to the SQL UDF or change the UDF definition to expect BIT 
DATA columns.
