Description

 

i want to create a view schema with mysql lexis, i write sample code like others, but follow error occurs ;

// code placeholder
public static void main(String[] args) throws SQLException {

     Properties info = new Properties();
     info.setProperty("lex", "MYSQL");
     info.setProperty("defaultNullCollation", "LAST");

     info.put(InternalProperty.CASE_SENSITIVE, false);
     info.put(InternalProperty.UNQUOTED_CASING, Casing.UNCHANGED);
     info.put(InternalProperty.QUOTED_CASING,Casing.UNCHANGED);

     Connection connection =
             DriverManager.getConnection("jdbc:calcite:", info);
     CalciteConnection calciteConnection =
             connection.unwrap(CalciteConnection.class);
     SchemaPlus rootSchema = calciteConnection.getRootSchema();

     SchemaPlus schema = rootSchema.add("test", new AbstractSchema());
     TableFunction simple =
             TableFunctionImpl.create(Types.lookupMethod(ViewTest.class, "simple"));
     SchemaPlus s = rootSchema.add("si", new AbstractSchema());
     s.add("simple",simple);

     String sql = " select * from table(si.simple())";

     schema.add("emps_view",
             ViewTable.viewMacro(schema,
                     sql,
                     null, Arrays.asList("test", "emps_view"), null));


     String qrySql = "select *from test.emps_view";

     final PreparedStatement ps = connection.prepareStatement(qrySql);
     ResultSet resultSet = ps.executeQuery();

     PrintUtil.output(resultSet, System.out);
 }
