Error description

  • Here is a problem reproducible steps.

db2 -v "create table s1.t1(a int)"
db2 -v "insert into s1.t1 values(3)"
db2look -d db1 -f -m -r -l -a -e -o db2look.txt

In db2look.txt, search keyword WHERE TABNAME = 'T1' AND
TABSCHEMA = 'S1', and one can find there is UPDATE
SYSSTAT.INDEXES statement even if there is no index in
table t1.

This is caused by V11.1 Mod3 FP3 integrated APAR IT17532
regression.

IT17532: SQL1227N CAN OCCUR WHEN APPLYING STATISTICS TAKEN BY
DB2LOOK -M -R
https://www-01.ibm.com/support/docview.wss?uid=swg1IT17532

There is no workaound so users may need to remove that
UPDATE SYSSTAT.INDEXES statement manually.  Or simply ignore.
