[jira] [Created] (SPARK-25457) IntegralDivide (div) should not always return long

Marco Gaido created SPARK-25457:
-----------------------------------

             Summary: IntegralDivide (div) should not always return long
                 Key: SPARK-25457
                 URL: https://issues.apache.org/jira/browse/SPARK-25457
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.5.0
            Reporter: Marco Gaido


The operation {{div}} returns always long. This came from Hive's behavior, which is different to the  one of most of other DBMS (eg. MySQL, Postgres) which return as a datatype the same of the operands.

This JIRA tracks changing our return type and allowing the users to re-enable the old behavior using {{spark.sql.legacy.integralDiv.returnLong}}.

I'll submit a PR for this soon.
