[jira] [Commented] (DRILL-319) Drill function need specify how to
handle error.
[ https://issues.apache.org/jira/browse/DRILL-319?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13844161#comment-13844161 ]
Rohit commented on DRILL-319:
-----------------------------
I think we should make use of AOP for this for intercepting the exceptions raised. Also provide a mechanism to register exceptions as per 3 categories via different annotations.
Let me know your thoughts.
If no one is working on this. I would like to start on this.

> Currently, drill's built-in function will raise Exception when it catches one, and stops the execution immediately.
> Depending on the nature of the function or the query, we might need allow function behaviors differently :
> -- Issue SQL Error code, and stop the execution.
> -- Issue SQL warning, continue the execution for the next row.
> -- Continue the execution for the next row, and log the # of error / warning for user awareness.
> Therefore, we need have a way to specify the different strategy how to handle error for different function implementation, for either build-in function, or UDF.
