> JDBC ResultSetMetadata methods getPrecision(...), getScale(...), and getColumnDisplaySize() are not implemented, currently because required data is not available in the RPC-level data.
> The required data includes:
> - string type lengths (N in VARCHAR(N), BINARY(N))
> - interval qualifier information (which units, leading digit precision, fractional seconds precision
> - datetime type fractional seconds precision
