[jira] [Created] (CALCITE-4427) Make SUBSTRING operator comply with ISO standard SQL

Julian Hyde created CALCITE-4427:
------------------------------------

             Summary: Make SUBSTRING operator comply with ISO standard SQL
                 Key: CALCITE-4427
                 URL: https://issues.apache.org/jira/browse/CALCITE-4427
             Project: Calcite
          Issue Type: Bug
            Reporter: Julian Hyde


Make {{SUBSTRING}} operator comply with ISO standard SQL. It currently complies with BigQuery standard SQL, which gives different behavior when start is negative. See discussion in CALCITE-4408.

Add an option to get the BigQuery behavior, for those who want it.
