DB2 FOR LUW / DB2FORLUW / 970 - DB2

In similar queries where we are doing an INSERT FROM SELECT 
during DPF we might encounter an instance crash because temp 
records are prematurely cleaned up in coordinator node. 
 
Sample Query: 
 
select 
case when exists 
        ( select prj.PROJECT_ID from project prj 
        INNER JOIN irb_protocol irbp on irbp.PROJECT_ID = 
prj.PROJECT_ID AND prj.PROJECT_ID = ? 
        INNER JOIN RULE_IRB_PROTOCOL rirbp on 
rirbp.IRB_PROTOCOL_ID = irbp.IRB_PROTOCOL 
        INNER JOIN RULE r on rirbp.RULE_ID = r.RULE_ID AND 
r.FILTER = 'Filter 5' 
        where 'Y' = 
            ( Select Coalesce(researchOptOut, 'N') 
            from Demographics d, 
xmltable('$d/Person/demographicsCollection/demographics 
                                [(effectiveStartTimeStamp <= 
$curruntT) and (effectiveEndTimeStamp >= $curruntT)]' 
                                passing  current timestamp as 
"curruntT", d."XMLDATA" as "d" 
                                columns researchOptOut 
VARCHAR(24) path './../../researchOptOut' ) ex 
                                where upi = (Select ex.upi 
                                            from 
xmltable('$d/child::node()/personUpi' 
                                            passing  cast(? as 
XML) as "d" 
                                            columns upi 
VARCHAR(24) path '.') ex ) 
            ) 
        ) 
then 1 else 0 end from sysibm.sysdummy1
