> Handle errors during constant reduction
> ---------------------------------------

> Key: CALCITE-1439
> URL: https://issues.apache.org/jira/browse/CALCITE-1439
> Project: Calcite
> Issue Type: Bug
> Reporter: Julian Hyde
> Assignee: Julian Hyde
> Fix For: 1.12.0
>
>
> A literal is a constant, and so a cast of a literal is also a constant, but
> when we do constant reduction sometimes there are errors if the cast is not
> valid. For example, the query
> {code}
> values cast('' as integer)
> {code}
> gives {{ExceptionInInitializerError}} and, to make matters worse, the Avatica
> JDBC driver does not catch the exception (because it is a
> {{java.lang.Error}}) and wrap it as a {{java.sql.SQLException}} as it ought
> to.
> Note that {{cast('1.2' as integer)}} is also invalid but {{cast(' -1 ' as
> integer)}} is valid.
> This issue probably also applies to divide-by-zero and other exceptions
> evaluating scalar expressions.
