DB2 FOR LUW / DB2FORLUW / 950 - DB2

XMLTABLE may return partially duplicated result when the data 
extracted is extracted as CLOB, when the data length is longer 
than 1800 bytes.  The resulting data looks like it is 
duplicated, but the last few bytes of the first occurence of the 
data are missing. 
 
A sample query that might result in such error is: 
 
SELECT Y.* 
  FROM SYSIBM.SYSXSROBJECTCOMPONENTS AS X, 
  XMLTABLE ( 
    XMLNAMESPACES('http://www.ibm.com/xmlns/prod/db2/xdb1' AS 
"xdb", 
                  'http://www.ibm.com/xmlns/prod/db2/mon'  AS 
"mon"), 
    '$d/xs:schema/xs:annotation/xs:appinfo/xdb:table' 
    passing XMLPARSE(DOCUMENT X.COMPONENT STRIP WHITESPACE) as 
"d" 
    COLUMNS 
     CREATESTMT    CLOB(32672)      PATH 
'upper-case(normalize-space(mon:createStmt/text()))' 
     ) AS Y; 
 
The problem will not happen if CLOB(32672) in the above query is 
replaced with VARCHAR(32672).

Use VARCHAR instead of CLOB when the expected result is greater 
than 1800 bytes
