A B commented on DERBY-3061:
----------------------------
I ran the repro with svn # 541822 ant it fails with an ASSERT failure:
shared.common.sanity.AssertFailure: ASSERT FAILED All multi-probing result sets
are expected to have a single key that is both the start key AND the stop key,
but that is not the case.
at shared.common.sanity.SanityManager.ASSERT(SanityManager.java(Compiled
Code))
at
impl.sql.execute.MultiProbeTableScanResultSet.<init>(MultiProbeTableScanResultSet.java:158)
...
But that ASSERT was removed as part of changes for DERBY-2740, hence no failure
in 10.3.1.4 nor latest runk. It looks like that fix was intended to allow
different start/stop keys to work (hence the assertion was removed), but
apparently it does not do the correct thing after all.
> Wrong results from query with two conjuncts

> Key: DERBY-3061
> URL: https://issues.apache.org/jira/browse/DERBY-3061
> Project: Derby
> Issue Type: Bug
> Components: SQL
> Affects Versions: 10.3.1.4
> Reporter: Rick Hillegas
> Priority: Critical
>
> 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 );
