I was hoping I had solved it
> Lossy CAST is incorrectly simplified
> ------------------------------------
>
> Key: CALCITE-4806
> URL: https://issues.apache.org/jira/browse/CALCITE-4806
> Project: Calcite
> Issue Type: Bug
> Reporter: xuyang
> Assignee: xiong duan
> Priority: Major
>
> the sql is following:
> {code:java}
> // code placeholder
> select cast(1.1 as int) = cast (1 as int){code}
> In SQLite the result is 1 and in postgreSQL the result is true.
> But in calcite the result is false.
> The bug is in RexSimplify and 1.1 and 1 are all converted to
> java.lang.Comparable, and 1.1 doesn't equal to 1. It ignores the source data
> type. The literal 1.1 should be cast to 1(int) first.
