Julian Hyde commented on CALCITE-6265:
--------------------------------------
Sure, it shows up in Calcite, but it's due to Avatica not doing (what I claim
to be) its job. If Avatica has a method that it says returns positive integers,
and Calcite divides by the result of that method, Avatica is at fault, even
though the divide-by-zero exception comes from Calcite code.

> Key: CALCITE-6265
> URL: https://issues.apache.org/jira/browse/CALCITE-6265
> Project: Calcite
> Issue Type: Bug
> Components: core
> Reporter: Tim Nieradzik
> Assignee: Tim Nieradzik
> Priority: Major
> Labels: pull-request-available
>
> The _empid_ column is of type {_}INT{_}. When providing a _short_ value as a
> placeholder, a _ClassCastException_ is thrown.
> *Test case:*
> {{ final String sql =}}
> {{ "select \"empid\" from \"hr\".\"emps\" where \"empid\" in (?,
> ?)";}}{{ CalciteAssert.hr()}}
> {{ .query(sql)}}
> {{ .consumesPreparedStatement(p -> {}}
> {{ p.setShort(1, (short) 100);}}
> {{ p.setShort(2, (short) 110);}}
> {{ })}}
> {{ .returnsUnordered("empid=100", "empid=110");}}
> *Stack trace:*
> {{java.lang.ClassCastException: class java.lang.Short cannot be cast to class
> java.lang.Integer (java.lang.Short and java.lang.Integer are in module
> java.base of loader 'bootstrap')}}
> {{ at Baz$1$1.moveNext(Unknown Source)}}

> org.apache.calcite.linq4j.Linq4j$EnumeratorIterator.<init>(Linq4j.java:679)}}
