When the statement includes XML predicates such as XMLEXISTS,
filters within XMLTABLE, or native XQuery and it accesses XML
indexes, it may fail with SQL0901N error. This issue is in only
applicable to v10.5 FP5 and v10.5 FP6 and does not affect
earlier fixpaks or releases.
The combination of XML with ROWNUM in a predicate and the FOR
FETCH ONLY clause will be a little more susceptible of this
issue flow.
For example, when processing from JCC, db2 does some checks
for the based on the cursor type and then invokes the processing
equivalent to the FOR FETCH ONLY clause, and the endpoint
SystemOut.log will have the following exception:
ConnectionEve A J2CA0056I: The Connection Manager received a
fatal connection error from the Resource Adapter for resource
jdbc/activities. The exception is:
com.ibm.db2.jcc.am.SqlException: The SQL statement or command
failed because of a database system error. (Reason
"sqlnq_qtbtbuerchild::delpr[ 10]:rc( 0) ").
SQLCODE=-901, SQLSTATE=58004, DRIVER=3.68.61
And the following messsage will be logged in db2diag.log in
this case.
