Julian Hyde commented on CALCITE-585:
-------------------------------------

Yes. 

Rather than throwing directly, can you please call a method: {code}throw 
connection.helper.unsupported();{code}. Then we can add more info by 
refactoring that method. Also, please add a test for one or two of the methods 
to make sure they continue to throw.

> Calcite throw UnsupportedOperationException instead of 
> SQLFeatureNotSupportedException

> 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).
