liu ming commented on TRAFODION-1676:
-------------------------------------
The first improvement can be done in hive_scan.
It seems only SCAN operator knows the line number, or row id of a given row.
One general improvement can be to add messages to show which column the data is
related.
> support better runtime error message when a SQL function meet fital error

> Key: TRAFODION-1676
> URL: https://issues.apache.org/jira/browse/TRAFODION-1676
> Project: Apache Trafodion
> Issue Type: Improvement
> Components: sql-exe
> Reporter: liu ming
> Assignee: liu ming
> Priority: Minor
>
> A sql contains some SQL function, for example UPPER(), when the input data of
> UPPER() contains invalid data, UPPER() will fail. In this case, the whole
> query abort, and the error message cannot tell which row has invalid data, so
> it is very hard to fix the problem.
> It will be good to have row id or the real value of the error row in the
> error message to help trouble shooting.
