Jacques Nadeau commented on DRILL-3540:
---------------------------------------
A short term solution may be to add JDBC support for using the convert to JSON
functionality that the ODBC driver uses. We could then add to default
connection strings so that SQLLine isn't calling tostring on a complex object.
> SQLline calls toString to convert complex columns into JSON. This
> translation doesn't work for some types
