## ORMX
Convertir datos entre el sistema de tipos utilizado en un lenguaje de programación orientado a objetos
## Ejemplos
Simple CRUD
```java
@TableInfo(name = "tb_nota")
public class Nota {
// Variables
@ColumnInfo(primaryKey = true, autoIncrement = true)
public long id;
@ColumnInfo
public long fecha;
@ColumnInfo
public String texto;
// Constructor
public Nota() {
// TODO Auto-generated constructor stub
}
// Funciones
/**
* @return una lista del recurso.
*/
public static List getAll() {
DB db = DB.db;
try {
return db.queryBuilder()
.order_by("fecha", "desc")
.get_list(Nota.class);
} finally {
db.close();
}
}
/**
* Guarda el registro.
*
* @param o modelo
*
* @return boolean TRUE exito FALSE fallo
*/
public static boolean save(Nota o) {
return (o.id == 0) ? insert(o) : update(o);
}
/**
* Inserta un registro en la db.
*
* @param o modelo
*
* @return boolean TRUE exito FALSE fallo
*/
public static boolean insert(Nota o) {
DB db = DB.db;
try {
return db.dao(Nota.class)
.insert(o);
} finally {
db.close();
}
}
/**
* Actualiza un registro en la db.
*
* @param o modelo
*
* @return boolean TRUE exito FALSE fallo
*/
public static boolean update(Nota o) {
DB db = DB.db;
try {
return db.dao(Nota.class)
.update(o) > 0;
} finally {
db.close();
}
}
/**
* Elimina un registro.
*
* @param id identificador
*
* @return boolean TRUE exito FALSE fallo
*/
public static boolean delete(long id) {
DB db = DB.db;
try {
return db.dao(Nota.class)
.deleteById(id) > 0;
} finally {
db.close();
}
}
public static OrmIterator query(String q, Date date) throws SQLException {
DB db = DB.db;
QueryBuilder query = db.dao(Nota.class).queryBuilder()
//.select("*")
//.distinct()
//.from("tb_nota")
.where("CAST(fecha AS DATE)", "=", date.getTime())
.like("texto", q)
//.where_in("id", 50, 60, 30)
//.or_where_in("id", 22, 44)
//.where("id", ">", 14)
//.where_not_in("id", 50, 60, 30)
//.or_where_not_in("id", 22, 44)
//.not_like("texto", "jet")
//.join("tb_nota b", "tb_nota.id = b.id")
//.join("tb_nota c", "tb_nota.id = c.id", "LEFT")
.order_by("fecha", "DESC").order_by("id", "DESC")
//.group_by("tb_nota.id")
//.group_by("tb_nota.texto")
//.having("tb_nota = 'Hello world'")
//.limit(7, 25)
;
return query.get_it(Nota.class); // Iterator
// return query.get_list(Nota.class); // List
// return query.get(Nota.class); // OrmResult
// return query.get_first(Nota.class); // Nota
// return query.get_select_count("*"); // long
}
}
```
### Config database
```java
public class DB extends OrmDataBase {
// Constantes
public static final String NAME = "notas.db";
public static final int VERSION = 1;
public static DB db = null;
// Constructor
private DB(Context context) {
super(context, NAME, null, VERSION);
}
// Funciones
@Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("CREATE TABLE tb_nota ("
+ "id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, "
+ "fecha INTEGER, "
+ "texto TEXT)");
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
if (oldVersion < newVersion) {
db.execSQL("DROP TABLE IF EXISTS tb_nota");
this.onCreate(db);
}
}
public static void init(Context applicationContext) {
db = new DB(applicationContext);
db.getWritableDatabase();
}
}
```
```java
DB.init(getApplicationContext());
```
