If you run a XQUERY with a substring function as below example
to a table which has multi-byte charactors, you may see below
messages at db2diag.log and the associated trap file
(t4539.000) has similar stack trace (CALLSTCK) as belows.
The XQUERY can not be run and will not return rows but SQL901N
error.
An example XQUERY:
---------------------------------------------------------------
XQUERY (for $a in db2-fn:xmlcolumn("REPORT.REPORTDOC")/
reportdoc where $a/status = "AAA" and $a/approve_info/
appCurrentInfo[@userID = "BBB" and @domain = "BPR"]
order by $a/date/sDate descending return <doc> {$a/@pdocID}
{$a/contents/subject} <body>{substring($a/contents/body, 1,
100)}</body> {$a/owner_info/name} {$a/date/sDate} </doc> )
[position() <= 50];
---------------------------------------------------------------
