      Wrong query result

      Description

      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
      ----------------------------------------

      ij> create index i on t;
      0 rows inserted/updated/deleted
