IT31278: DB2LOOK -M -R CREATE UPDATE SYSSTAT.INDEXES STATEMENT FOR TABLE EVEN WHEN TABLE HAS NO INDEX

APAR status

• Closed as program error.

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.
