Bryan Pendleton updated DERBY-1773: ----------------------------------- Attachment: anyVsAll.diff updatedToHeadMarch2016.diff Uhm, I guess I lost track of this issue, for it's been 6 years! :) The first thing I did was to bring the previous patch up to date, since a lot can change in 6 years. 'updatedToHeadMarch2016.diff' is the result, and it builds and passes tests with the head of trunk. Upon closely re-reading Knut Anders's comments from 6 years ago, I remembered that I had not addressed his observation that it would be possible for some, but not all, of the columns in the result list to be aliased, and only those columns which are aliased should be non-updatable; the unaliased columns should still be updatable. After thinking about that for a while, it seemed to me that this merely required changing the proposed ResultColumnList.columnsAreUpdatable() method so that it tested whether *any* columns in the list were updatable, as opposed to requiring that *all* columns in the list were updatable. So I did that, and added a few additional test cases, and the results appear to be satisfactory. The revised patch is attached as anyVsAll.diff. I'm running tests on it now, to see how it behaves. Sorry for the 6 year gap, but if anyone is still interested in this issue, feedback would be gratefully received. > insertRow() and updateRow() fail with syntax error when column has an alias > --------------------------------------------------------------------------- > > Key: DERBY-1773 > URL: https://issues.apache.org/jira/browse/DERBY-1773 > Project: Derby > Issue Type: Bug > Components: JDBC > Affects Versions: 10.2.1.6 > Reporter: Knut Anders Hatlen > Assignee: Bryan Pendleton > Priority: Minor > Labels: derby_triage10_5_2 > Attachments: ASF.LICENSE.NOT.GRANTED--Alias.java, > NoUpdatesToAliasedColumnsWithTest.diff, anyVsAll.diff, > updatedToHeadMarch2010.diff, updatedToHeadMarch2016.diff > > > When the select query used in an updatable result set has column aliases, a > syntax error is thrown when executing ResultSet.insertRow() and > ResultSet.updateRow().
