Subject [jira] Updated: (DERBY-2500) Assertion failure preparing query with AND and OR in where clause
Date Thu, 29 Mar 2007 23:45:25 GMT

     [ https://issues.apache.org/jira/browse/DERBY-2500?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

A B updated DERBY-2500:

    Attachment: d2500_v2.patch

Realized after I uploaded the patch that the comments for the test case in DistinctTest need
to be updated to reflect the changes made in this issue.  Other than this change to the comments,
v1 and v2 are identical.

>    Affects Versions:
>            Reporter: Andrew McIntyre
>         Assigned To: A B
>         Attachments: d2500_v1.patch, d2500_v1.stat, d2500_v2.patch
> See commented out test in DistinctTest, DistinctTest.testResultSetInOrderWhenUsingIndex.
> The actual assert is:
> ASSERT FAILED Found IN-list probing (NLR.LUSERNAME = <expr>) while generating HASH
join, which should not happen.
> I was able to simplify the query a little:
> SELECT DISTINCT nb.name AS name, nb.summary AS summary FROM netbutton1 nb, netbuttonlibraryrole1
nlr, library_netbutton ln WHERE nlr.netbuttonlibrary_id = ln.netbuttonlibrary_id AND (nlr.lusername
= ? OR nlr.lusername =?)
> Removing nlr.netbuttonlibrary_id = ln.netbuttonlibrary_id clause but leaving the 'nb.lname
= ln.lname' in front of the AND did not reproduce the problem.
