Jdbc driver can't understand data type "Nothing" and fails to execute query.

[nikhilbhawsar]

Describe the bug

We have table at Clickhouse DB with columns having datatype Nullable(Nothing). We are using Spotfire desktop with latest version of CH drivers (0.6.0). While executing simple select query, it fails and throws error..

Steps to reproduce

1. Create/Add column of type Nullable(Nothing)
2. Use latest version of CH driver and use it at Spotfire
3. Call "select" query for table having that column

Expected behaviour

it should run and show results from that table.

Code example

Error log

com.spotfire.ws.im.IMException: Failed to execute query: Unsupported JDBC data type in query result: Nullable(Nothing)
