----------------------------------------------
Hi [~siddteotia], it seems you are describing a bug. Can you change the summary
/description to better explain how and when it appears. If you have an SQL
statement that fails it would be nice to include it also.

> URL: https://issues.apache.org/jira/browse/CALCITE-2829
> Project: Calcite
> Issue Type: Bug
> Reporter: Siddharth Teotia
> Assignee: Julian Hyde
> Priority: Major
>
> Range expressions like <ts> = 'literal' AND <ts> < 'literal' trigger
> ClassCastException as literal are implicitly casted differently between =/<>
> operators and other comparison operators. Apply the same casting rules for
> comparison to =/<> calls when processing ranges, so that all the terms have
> the same type for literals.
