------------------------------------
Labels: pull-request-available (was: )
> AVG aggregate function return wrong type
> ----------------------------------------
>
> Key: CALCITE-6830
> URL: https://issues.apache.org/jira/browse/CALCITE-6830
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.39.0
> Reporter: Lantao Jin
> Priority: Major
> Labels: pull-request-available
>
> To reproduce (agg.iq)
> {code:java}
> !use post
> !set outputformat mysql
> SELECT avg(deptno) as a FROM emp;
> {code}
> Should return 22.1429, but returns 22.
> This behavior is different from other databases.
> Since the AVG agg with integer argument returns wrong type, the behaviors of
> var_pop, var_samp, stddev_pop, stddev_samp and stddev are wrong either.
