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

    Derby Info: [Regression]

Verified that this is a regresssion.  Running against  10.2.2.1.545663  I see:


ij> select mytable.id
from mytable
where mytable.id < 100
and mytable.id in ( 2, 15, 19, 20, 21, 48, 49 );
ID

>          Issue Type: Bug

> Tim Dudgeon, on the user list, reports that the following query returns no results in 10.3.1.4 but works correctly in 10.2. I have verified that the query returns no results in the mainline as well. If you eliminate either of the the conjuncts, then the query returns the correct results:
> SELECT MYTABLE.MY_ID
>  FROM MYTABLE
>  WHERE MYTABLE.MY_ID < 100 AND MYTABLE.MY_ID IN (
> 2,15,19,20,21,48,49
> )
> Here is a more complete script which demonstrates the problem:
> drop table mytable;
> create table mytable ( id int primary key );
> insert into mytable ( id )
> values
> ( 0 ), ( 1 ), ( 2 ), ( 3 ), ( 4 ), ( 5 ), ( 6 ), ( 7 ), ( 8 ), ( 9 );
> insert into mytable select id + 10 from mytable;
> insert into mytable select id + 20 from mytable;
> insert into mytable select id + 40 from mytable;
> insert into mytable select id + 100 from mytable;
> select mytable.id
> from mytable
> where mytable.id < 100;
> select mytable.id
> from mytable
> where mytable.id in ( 2, 15, 19, 20, 21, 48, 49 );
> select mytable.id
> from mytable
> where mytable.id < 100
> and mytable.id in ( 2, 15, 19, 20, 21, 48, 49 );
