> Methods {{Statement#getMoreResults}} and {{Statement#getMoreResults(int)}} are currently throwing a {{SQLFeatureNotSupportedException}}, but at least one tool (DataGrip) is calling the first method after each SQL request.
> Avatica doesn't support multiple {{ResultSet}} for a given {{Statement}} (see [https://github.com/apache/calcite-avatica/blob/master/core/src/main/java/org/apache/calcite/avatica/AvaticaDatabaseMetaData.java#L1148]), so a basic implementation could close the current open result set (if any), and return {{false}} for both methods (unless the int argument is equal to {{Statement.KEEP_CURRENT_RESULT}} or {{Statement.CLOSE_ALL_RESULTS}}).
