Pressenna commented on CALCITE-3230:
------------------------------------
[~danny0405], I apologise.
It turned out that Calcites definition of AVG did not match our internal
definition of AVG.
Calcite expects AVG(input type) return a vale of input type.
Our internal implementation always returns a double for AVG.
Again, i apologise.
I close this ticket as invalid and will make sure to create reproducible tests
before submitting more issues.
> Explicit CASTs by user are not applied.

> Project: Calcite
> Issue Type: Bug
> Components: core
> Reporter: Pressenna
> Priority: Major
>
> For some reason casting is not working correctly with aggregate functions.
> for example:
> {code:java}
> SELECT CAST(AVG(double_column) AS float) FROM foo GROUP BY group_coulmn;
> {code}
> does not apply the cast. We currently have to circumvent this by using
> following dummy construct.
> {code:java}
> SELECT CAST( (AVG(double_column) + 0.0) AS float) FROM foo GROUP BY
> group_coulmn;
> {code}
