Kim Haase updated DERBY-6116:
-----------------------------
Issue & fix info: Patch Available
> Confusing description of limitation on user-defined aggregate names.
> --------------------------------------------------------------------
>
> Key: DERBY-6116
> URL: https://issues.apache.org/jira/browse/DERBY-6116
> Project: Derby
> Issue Type: Bug
> Components: Documentation
> Affects Versions: 10.10.1.1
> Reporter: Rick Hillegas
> Assignee: Kim Haase
> Labels: derby_triage10_11
> Attachments: DERBY-6116.diff, rrefsqljcreateaggregate.html
>
>
> The Reference Manual section titled "CREATE DERBY AGGREGATE statement" makes
> the following ambiguous claim:
> "An unqualified UDA name may not be the name of an aggregate defined in part
> 2 of the SQL Standard, section 10.9"
> The term "unqualified UDA name" is supposed to mean the name of the UDA
> without any schema name. So if the full, schema qualified name of the UDA is
> MYSCHEMA.FOO, then FOO may not be a SQL Standard aggregate name like MAX,
> MIN, ANY, etc..
> This was not clear during buddy-testing of UDAs. From the wording in the
> Reference Manual, the buddy-tester expected to be able to create an aggregate
> called APP.ANY.
