OQL guide

data class:

public class Country implements Declarable {
   String name;
   String capitol;
   Set languages;
   Map province;
   int population;

  public boolean isBigCountry(){
    return population > 100000 && province.size() > 20;
  }
}

region data structure: Region
regionCountry.put(country.getName(), country)

OQL:
debug:
 select * from /Country

list keys:
select * from /Country.keys
select * from /Country.keySet
SELECT key, langs FROM /Country.entrySet entry, entry.value.languages langs WHERE langs.size > 3

invoke java method:
select * from /Country c where c.capitol.equalsIgnoreCase('portland')
select * from /Country c where c.isBigCountry

comments:
SELECT *  FROM /exampleRegion /* here is a comment */ WHERE status = 'active'

MIN, MAX, AVG, AVG, count Function: 
SELECT count(e) FROM /Country e WHERE e.population > 10
-- sales should evaluate to java.lang.Number and java.lang.Comparable

the same result:
SELECT DISTINCT * FROM /Country p WHERE p.name = '1'
SELECT DISTINCT * FROM /Country p WHERE p.Name = '1'
SELECT DISTINCT * FROM /Country p WHERE p.getName() = '1'

like: 
SELECT * FROM /Country p WHERE p.name LIKE 'china'

IN and SET: 
SELECT * FROM /Country WHERE languages = set('eng','chinese','jap')
SELECT * FROM /Country WHERE languages.containsAll(set('eng','chinese','jap'))

SELECT name, capitol FROM /Country WHERE name IN (SELECT id FROM /portfolios WHERE status = 'active')

Map: 
SELECT entry.key, entry.value FROM /Country.entries entry WHERE entry['name'] = 'china'
SELECT entry.key, entry.value FROM /Country.entries entry WHERE entry.province['name'] = 'shanghai'

Map and Array:
SELECT * FROM /exampleRegion p WHERE p.collectionHolderMap.get('1').arr[0] = '0'

--- advance query 

AS:`
SELECT DISTINCT key.ID, key.status AS st FROM /exampleRegion.keys key 
WHERE key.status = 'inactive' ORDER BY key.status desc, key.ID LIMIT 1

Join: 
SELECT portfolio1.ID, portfolio2.status FROM /exampleRegion portfolio1, /exampleRegion2 portfolio2 
WHERE portfolio1.status = portfolio2.status

useing TRUE:
SELECT DISTINCT * FROM /Portfolios WHERE TRUE

Using IMPORT and Using TYPE:
IMPORT package.Position;
SELECT DISTINCT * FROM /exampleRegion, positions.values positions TYPE Position WHERE positions.mktValue >= 25.00

Using ELEMENT
ELEMENT(SELECT DISTINCT * FROM /exampleRegion WHERE id = 'XYZ-1').status = 'active'

Using parameters query:
String queryString = "SELECT DISTINCT * FROM /exampleRegion p WHERE p.status = $1";
Query query = queryService.newQuery(queryString);
Object[] params = new Object[1];
params[0] = "active";
SelectResults results = (SelectResults) query.execute(params);
