-------------------------------------
Summary: Use highest input precision for datetimes in
SqlTypeFactoryImpl.leastRestrictive
Key: CALCITE-5478
URL: https://issues.apache.org/jira/browse/CALCITE-5478
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Gian Merlino
For example: {{leastRestrictive(TIMESTAMP(3), TIMESTAMP(0))}} would be
{{TIMESTAMP(3)}}, not {{TIMESTAMP(0)}}.
Some code exists to do this for other types, but not datetimes.
