-----------------------------------------------------------------

[~jamesstarr], The desired behavior is that SUBSTR will give the semantics of database {{xxx}} based on your connection's {{fun=xxx}} setting.

The JDBC adapter will have to be clever in generating SQL to make sure that that happens. (Meaning: We have some bugs to fix.)

> 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.
