--------------------------------------
I have a fix for this issue, but it needs a fix for [CALCITE-5921] first, so I
will submit that one first.
> Explicit cast to numeric type doesn't check overflow
> ----------------------------------------------------
>
> Key: CALCITE-5990
> URL: https://issues.apache.org/jira/browse/CALCITE-5990
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.35.0
> Reporter: Runkang He
> Assignee: Runkang He
> Priority: Blocker
> Fix For: 1.36.0
>
>
> Explicit cast to numeric type doesn't check overflow, and this issue can be
> reproduced by sqlline:
> {code:sql}
> select cast(empno as tinyint), cast(130 as tinyint) from emps where
> name='Alice'; -- empno is 130
> {code}
> The empno is INT type. The result is wrong:
> {code:sql}
> -126, -126{code}
> I think it should throw exception when overflow, instead of returning wrong
> result to user.
> At last, this issue was found when to turn on runtime check for
> CalciteSqlOperatorTest in CALCITE-5921.
