------------------------------------
The *div* function binds on this particular expressions

. I am not sure that we can replace it during analysis.
> IntegralDivide's dataType should not depend on SQLConf.get

> Key: SPARK-30858
> URL: https://issues.apache.org/jira/browse/SPARK-30858
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Herman van Hövell
> Priority: Blocker
>
> {{IntegralDivide}}'s dataType depends on the value of
> {{SQLConf.get.integralDivideReturnLong}}. This is a problem because the
> configuration can change between different phases of planning, and this can
> silently break a query plan which can lead to crashes or data corruption.
