Proposed syntax change

[MattCremeens]

I believe you need to change

SqlOperatorTable operatorTable = ChainedSqlOperatorTable.of( SqlStdOperatorTable.instance() );

to

SqlOperatorTable operatorTable = SqlOperatorTables.chain(SqlStdOperatorTable.instance());

Additionally, I believe the new approach requires a change from

SqlToRelConverter.Config converterConfig = SqlToRelConverter.configBuilder()
            .withTrimUnusedFields(true)
            .withExpand(false) // https://issues.apache.org/jira/browse/CALCITE-1045
            .build();

to

SqlToRelConverter.Config converterConfig = SqlToRelConverter.config()
                .withTrimUnusedFields(true)
                .withExpand(false);
