------------------------------------
Assignee: Mihai Budiu
> RexCall should carry source position information for runtime error reporting
> ----------------------------------------------------------------------------

> Key: CALCITE-6071
> URL: https://issues.apache.org/jira/browse/CALCITE-6071
> Project: Calcite
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.35.0
> Reporter: Mihai Budiu
> Assignee: Mihai Budiu
> Priority: Minor
> Labels: pull-request-available
>
> Currently runtime errors, such as division by zero, cannot report the
> position in the original source code where the original operator was. RexNode
> does not carry such information. By adding the required information in
> RexNode we can report much better runtime errors to users.
> Here is an additional comment from [~jhyde] on the dev mailing list:
> The RexCall to such throwable functions would have a hidden ‘pos’ parameter.
> The parameter should be populated at Sql-to-rel time, and if it is not
> present, SqlOperator.validareRexOperands should throw. Associating the
> position with the particular function call seems to me much more robust than
> associating it with the RelNode that contains the call.
