| Problembeschreibung: | |
The issue can be reproduced in the following scenario:
1.
create table test1( a BIGINT NOT NULL,
b INTEGER NOT NULL)
distribute by hash(a)
partition by range (b)
(PART "PART0" STARTING('1') ENDING('10'),
PART "PART1" STARTING('11') ENDING('20'));
create index indx1 on sahanant.test1 (b);
runstats on table sahanant.test1 and indexes all set profile
only;
load from data.del of del MESSAGES "msgfile" REPLACE into
sahanant.test1 statistics use profile;
select substr(indname, 1, 10), nlevels, indcard, numrids from
syscat.indexpartitions where indname='INDX1'
1 NLEVELS INDCARD NUMRIDS
---------- ------- -------------------- --------------------
INDX1 0 3 3
INDX1 1 0 0
2 record(s) selected.
select substr(indname, 1, 10), nlevels, indcard, numrids from
syscat.indexes where indname='INDX1'
1 NLEVELS INDCARD NUMRIDS
