Ruben Q L commented on CALCITE-7746:
------------------------------------
[~mbudiu] I managed to come up with an implementation for this, it requires a
bit of extra "intelligence" on the SafeRexVisitor, but it should fix the
problem. Please take a look when you have a bit of time.
> Review operation safety on arithmetic on dates and intervals
> ------------------------------------------------------------
>
> Key: CALCITE-7746
> URL: https://issues.apache.org/jira/browse/CALCITE-7746
> Project: Calcite
> Issue Type: Task
> Components: core
> Reporter: Ruben Q L
> Priority: Major
> Labels: pull-request-available
>
> Currently, arithmetic operations on dates and intervals do not have any
> particular management (they are treated as any other operands).
> However, in this case arithmetic operations (even the standard, non-checked
> ones) can throw at runtime, so they should probably be reviewed and not
> considered "safe" in RexSimply.
> See disabled test with this ticket number in RexProgramTest.
