DB2 FOR LUW / DB2FORLUW / 950 - DB2

An example of a query that would cause the problem is: 
 
   select upi,document_id,doctext 
     from documents t1, 
     xmltable 
    ('$c/Document/documentDetailsCollection/documentDetails 
      [effectiveEndTimeStamp = 
xs:dateTime("2199-12-31T23:59:59") 
      and exists(deidentifiedDocumentText)]' 
      passing t1.xmldata as "c" 
      columns 
          doctext clob(2M) path './deidentifiedDocumentText' 
     ) as x ; 
 
  The crash will be more likely to happen when the size of the 
selected document is 87K or more. 
 
  The following error can be seen in the db2diag.log: 
 
  FUNCTION: DB2 UDB, lob manager, sqldxAppendLob, probe:608

Customer can break the column into multiple columns of 87K size 
or less using the substring function.  Example: 
 
select upi,document_id,doctext1,doctext2,.... 
     from documents t1, 
     xmltable 
    ('$c/Document/documentDetailsCollection/documentDetails 
      [effectiveEndTimeStamp = 
xs:dateTime("2199-12-31T23:59:59") 
      and exists(deidentifiedDocumentText)]' 
      passing t1.xmldata as "c" 
      columns 
          doctext1 clob(2M) path 
           './fn:substring(./deidentifiedDocumentText,1,86000)', 
          doctext2 clob(2M) path 
 
'./fn:substring(./deidentifiedDocumentText,86001,86000)', 
           ..... 
     ) as x ;
