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.
