Error in comparison test when using "group by"

[GoogleCodeExporter]

Hi,

I am using the version H2 1.3.175.
Here are the requests to reproduce the issue:

CREATE TABLE TEST(ID INT PRIMARY KEY, NAME VARCHAR(255));
insert into test values (1, 'test1');
insert into test values (2, 'test2');

select * from test;

Output:
ID      NAME  
1   test1
2   test2

select id,
name IN ('test2','test3') col
from test;

Output:
ID      COL  
1   FALSE
2   TRUE

select id,
name IN ('test2','test3') col
from test
group by id;

Expected output:
ID      COL  
1   FALSE
2   TRUE

Seen output:
ID      COL  
1   TRUE
2   TRUE

Thanks and regards.

Hi,

I finally had time to look at it and fixed the problem (in the trunk).

Regards,
Thomas

Should be fixed with version 1.4.187

Hello Thomas,

I think there is some regression caused by this fix, we have a request:

     SELECT 
       id, 
       COUNT(something), 
       CASE WHEN status in THEN SUM(something) ... END
     FROM ...
     GROUP BY id

And with 1.4.187, the driver throw an exception asking to put "status" in the 
"group by" (and that seems not correct). This was working fine with 1.4.186.

Best regards, 

Régis.

Hi,

If you have an error to report, please open a new issue (at GitHub, not here). 
And please include a _complete_, simple test case.

I think your query is not valid. I tested with PostgreSQL and it fails:

drop table test;
create table test(id int, something int, status int);
insert into test values(1, 1, 1);
insert into test values(2, 2, 2);

    SELECT 
       id, 
       COUNT(something), 
       CASE WHEN status in(1, 3) THEN SUM(something) else 0 END
     FROM test
     GROUP BY id;

Please don't reply to this. The Google Code project is closed.
