Another SQLite ORM and query DSL for ActionScript

As3Query

Another SQLite ORM and query DSL for Flex and Adobe Air

Uses Promises/A+ library.

Annotations list:

• Specify table name [Table(name="test")]
• Specify table index (or multiple indices) [Index(name="test_index_1", columns="unsigned,bool", unique="true")]
• Specify table column [Column(primaryKey, nullable="false", unique="true", foreignKey="table(id)", options="deferred", default="1")]

Usage:

1. Put annotations:

       [Table(name="test")]
       [Index(name="test_index_1", columns="unsigned,bool")]
       [Index(name="test_index_2", columns="str", unique="true")]
       public dynamic class TestEntity
       {
           [Column(primaryKey, nullable="false")]
           public var id:int;
   
           [Column(default="1")]
           public var unsigned:uint;
   
           [Column(unique="true")]
           public var date:Date;
   
           [Column]
           public var xml:XML;
   
           [Column]
           public var xmlList:XMLList;
   
           [Column]
           public var object:Object;
   
           [Column]
           public var bool:Boolean;
   
           [Column]
           public var num:Number;
   
           [Column]
           public var str:String;
   
           [Column(foreignKey="table(id)", options="deferred")]
           public var fk_table:int;
       }

2. Map entity:

       var entityManager:EntityMapper = new EntityMapper();
       entityManager.registerEntity(TestEntity);

3. Create tables:

        var connection:SQLConnection = new SQLConnection();
        connection.open(file, SQLMode.CREATE);
        try
        {
           new CreateTables(connection, [TestEntity], mapper).call();
        }
        finally
        {
            if(connection.connected)
            {
                connection.close();
            }
        }

4. Create session:

       var session:Session = new Session(mapper);
       session.open(file.nativePath, SQLMode.UPDATE).then(function ():void{ trace('ok') });

5. Perform different operations:

   Criteria

       session.criteria(TestEntity).by(Order.asc(TestEntity.ATTR_ID)).list.then(function (operation:ISQLOperation):void{ 
           trace(operation.result); 
       });
       session.criteria(TestEntity).when(Restrictions.Eq(TestEntity.ATTR_ID, 1)).unique.then(function (operation:ISQLOperation):void{ 
           trace(operation.result); 
       });
       session.criteria(TestEntity).when(Restrictions.Eq(TestEntity.ATTR_ID, 1)).count.then(function (count:int):void{ 
           trace(count); 
       });

   Create, update

       session.save(testCriteriaEntity1).then(function ():void{ trace('ok') });

   Delete

       session.remove(testCriteriaEntity1).then(function ():void{ trace('ok') });

   Transactions

       var transaction:ITransaction = session.transaction;
   
       transaction.insert(testCriteriaEntity1);
       transaction.insert(testCriteriaEntity2);
       transaction.remove(testCriteriaEntity2);
       
       transaction.run.then(function (operation:ISQLOperation):void{ 
           trace('ok'); 
       });

   Raw queries

      var query:IQuery = session.query;
      query.text = "update test set str=:str where str=:id";
      query.parameters[":id"] = "inserted2";
      query.parameters[":str"] = "inserted3";
      query.run.then(function (operation:ISQLOperation):void{ 
           trace('ok'); 
      });
