[jira] [Commented] (DERBY-672) Re-enable user defined aggregates
[ https://issues.apache.org/jira/browse/DERBY-672?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13447767#comment-13447767 ]

---------------------------------------
Hi Rick,
The user-defined aggregate name will not conflict with builtin function names, right? May be it is not even an issue for user-defined aggregates but I wanted to bring it up anyways. There is a pre-existing jira for conflict between user-defined function names with builtin functions DERBY-5901 (You can declare user-defined functions which shadow builtin functions by the same name. )

> Nicolas Dufour in an email thread titled "functions and list" started on November 2, 2005 requests the ability to create user defined aggregates.
> This functionality used to be in Cloudscape. It was disabled presumably because it was considered non-standard. However, most of the machinery needed for this feature is still in the code. We should re-enable user defined aggregates after we agree on acceptable syntax.
