Subject [jira] Commented: (DERBY-5005) Error when fully qualifying a field from a view in an ORDER BY clause
Date Mon, 14 Feb 2011 09:38:57 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5005?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12994245#comment-12994245
] 

Lukas Eder commented on DERBY-5005:
-----------------------------------

Should I verify the correctness of the fix before closing it? I'd have to wait for a release
(10.8, I guess) before I could close it. What's your preferred process?

> I have a strange issue that can be reproduced easily with the following objects in schema
"test":
> create table a (a integer);
> insert into a (a) values(1);
> create view v as select * from a;
> This works:
> select test.a.a from test.a where test.a.a <> 2 order by test.a.a asc;
> This doesn't work:
> select test.v.a from test.v where test.v.a <> 2 order by test.v.a asc;
> But this does:
> select test.v.a from test.v where test.v.a <> 2 order by v.a asc;
> This is the error I get:
> Error: 'TEST.V' is not an exposed table name in the scope in which it appears.
> SQLState:  42X10
> ErrorCode: -1
> I've tried quite a few SELECT clauses, and I think the ORDER BY clause is the only one
having this issue.
