      // FrameworksTest.java
       @Test public void testMinMax() throws Exception {
       Table table = new TableImpl();
       final SchemaPlus rootSchema = Frameworks.createRootSchema(true);
       SchemaPlus schema = rootSchema.add("x", new AbstractSchema());
       schema.add("MYTABLE", table);
       List<RelTraitDef> traitDefs = new ArrayList<>();
       traitDefs.add(ConventionTraitDef.INSTANCE);
       traitDefs.add(RelDistributionTraitDef.INSTANCE);
       SqlParser.Config parserConfig =
       SqlParser.configBuilder(SqlParser.Config.DEFAULT)
       .setCaseSensitive(false)
       .build();
      final FrameworkConfig config = Frameworks.newConfigBuilder()
       .parserConfig(parserConfig)
       .defaultSchema(schema)
       .traitDefs(traitDefs)
       // define the rules you want to apply
       .ruleSets(
       RuleSets.ofList(AbstractConverter.ExpandConversionRule.INSTANCE, ProjectTableScanRule.INSTANCE))
       .programs(Programs.ofRules(Programs.RULE_SET))
       .build();
      executeQuery(config, " select min(id) as mi, max(id) as ma from mytable where id=1 group by id",
       CalciteSystemProperty.DEBUG.value());
