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

I agree, such methods should throw SQLFeatureNotSupportedException. Feel free to submit a patch.

> The unsupported JDBC method are throwing UnsupportedOperationException.
> This cause calcite jdbc client program fail to catch the exception and goes to unhandled exception routine.  
> For example 
> AvaticaStatement.java
> public boolean getMoreResults() throws SQLException {
>     throw new UnsupportedOperationException();
>   }
> The expected exception for this is SQLFeatureNotSupportedException (a subclass of SQLException).
