Knut Anders Hatlen created DERBY-6025:
-----------------------------------------

             Summary: Wrong results with IN lists and indexes in territory based collation
                 Key: DERBY-6025
                 URL: https://issues.apache.org/jira/browse/DERBY-6025
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.9.1.0
            Reporter: Knut Anders Hatlen


The sequence below shows that a query returns 1 row when there is no index on the table, and
it returns 0 rows when an index is created. It should return 1 row regardless of the index's
presence.

ij version 10.9
ij> connect 'jdbc:derby:memory:colldb;create=true;territory=no;collation=TERRITORY_BASED';
ij> create table t(x varchar(40));
0 rows inserted/updated/deleted
ij> insert into t values 'Stranda Idrottslag', 'Aalesunds Fotballklubb';
2 rows inserted/updated/deleted
ij> select * from t where x in ('Aalesunds Fotballklubb', cast('xyz' as char(3)));
X                                       
----------------------------------------
Aalesunds Fotballklubb                  

1 row selected
ij> create index i on t(x);
0 rows inserted/updated/deleted
ij> select * from t where x in ('Aalesunds Fotballklubb', cast('xyz' as char(3)));
X
