DB2 FOR LUW / DB2FORLUW / A50 - DB2

The upgrade code was trying to construct runstats profile 
command checking for NULLability 
of statistics_profile column. But in reality , the runstats 
profile is deleted via view regeneration code. 
 
Simple repro script to see this behavior : 
 
In v97 , 
 
create db test 
connect to test 
create table t(c1 int, c2 int, c3 int) 
insert into t values(1,1,1) 
create view v as select * from t 
alter view v enable query optimization 
runstats on table samadesa.v WITH DISTRIBUTION ON COLUMNS(c1,c2) 
set profile 
select name , creator, substr(statistics_profile,1,50) from 
sysibm.systables where name ='V' 
alter view v disable  query optimization 
alter table t drop column c2 
select name , creator, substr(statistics_profile,1,50) from 
sysibm.systables where name ='V' 
connect reset 
 
db2cat -d test -p table -n V -s SAMADESA -t|egrep "^Table:|^ 
Stats Profile Offset"|gnugrep -B1 ": 0" 
 
hotel85:/home/hotel85/samadesa> |^ Stats Profile Offset"|gnugrep 
-B1 ": 0"   <

Now upgrade to v10 and you will get a trap in the same function 
while constructing runstats command.
