1.简介

全方位介绍: 最全面的介绍文档(点击这里)

为什么选择Moon.Orm?

1)发现实体框架不能满足大型系统中性能需求;(兄台就不要辩论了,咱们已经辩论太多累了:2015年5月1日13:59:46)

2)其他开源框架使用起来配置麻烦,如mybatis,nh..........

3)sql在VS中没有智能感知,如Dapper......

4)某些框架设计的一致性问题,语言晦涩.........

2.使用步骤

1.下载代码生成器生成model;

2.引用model及moon.orm到你的具体项目;

3.填写你的项目中配置文件;(关于配置文件:地址)

4.开始使用;

使用步骤:点击 去看看,这里很久以前的示例,大家可用新版本

注意:

1.请将数据库附加到您的数据库中.数据库下载地址: http://pan.baidu.com/s/1eQjIz7O

2.注意修改对应的配置文件中连接字符串;

  /// <summary> /// 添加实体对象的测试 /// </summary> /// <returns></returns> public static void TestAddEntity(){  using (var db=Db.CreateDefaultDb()) {   var startCount=GetProductCount();   Products p=new Products();   p.ProductName="ProductName"+DateTime.Now;   p.Quantity=100;   p.Remark="标记";   p.Unit="单元";   p.UnitPrice=12m;   p.CategoryId=3;   db.Add(p);   //克隆一个p对象,然后添加到数据库中   var p2=p.Clone<Products>();   db.Add(p2);   var endCount=GetProductCount();   Console.WriteLine("添加条数为:"+(endCount-startCount));  } } /// <summary> /// 删除实体对象的测试 /// </summary> public static void TestRemoveEntity(){  using (var db=Db.CreateDefaultDb()) {   var startCount=GetProductCount();   Products p=new Products();   p.ProductName="ProductName"+DateTime.Now;   p.Quantity=100;   p.Remark="标记";   p.Unit="单元";   p.UnitPrice=12m;   p.CategoryId=3;   db.Add(p);   //删除这条新加的数据   db.Remove<ProductsSet>(ProductsSet.ProductId.Equal(p.ProductId));   var endCount=GetProductCount();   Console.WriteLine("添加条数为:"+(endCount-startCount));  } } public static void TestUpdateEntity(){  using (var db=Db.CreateDefaultDb()) {   db.DebugEnabled=true;   var p=db.GetEntity<Products>(ProductsSet.SelectAll().Top(1));   Console.WriteLine(p.ProductName);   p.ProductName=p.ProductName+DateTime.Now;   p.Quantity=11;   //必须通过设置WhereExpression来指定需要更新哪些数据   //--的确让用户有点误解,但这样可以指定更广泛的合符条件的数据如>100 and a<100   p.WhereExpression=ProductsSet.ProductId.Equal(p.ProductId);   db.Update(p);   var sql=db.CurrentSQL;   p=db.GetEntity<Products>(ProductsSet.SelectAll().Top(1));   Console.WriteLine(p.ProductName);  } } 

2.mql查询语句

1)分组查询

  /// <summary> /// 测试group及having语句 /// </summary> public static DictionaryList TestHaving(){  using (var db=Db.CreateDefaultDb()) {   var mql=OrdersSet.Select(OrdersSet.OrderId.Count(),OrdersSet.CustomerId,OrdersSet.Finished)    .Where(OrdersSet.CustomerId.SmallerThan(20))    .GroupBy(OrdersSet.CustomerId,OrdersSet.Finished)    .Having(OrdersSet.OrderId.Count().BiggerThan(2)).Top(5);   var sql=mql.ToDebugSQL();//等价sql语句   var list=db.GetDictionaryList(mql);   return list;  } } 

SELECT TOP 5 COUNT([Orders].[OrderId]),[Orders].[CustomerId], [Orders].[Finished] FROM [Orders] WHERE  [Orders].[CustomerId]<@p1   GROUP BY [Orders].[CustomerId] ,[Orders].[Finished] HAVING   COUNT([Orders].[OrderId])>@p2  @p1=20 @p2=2

2)连接查询

  /// <summary> /// 测试join语句 /// </summary> public static DictionaryList TestJoin(){  using (var db=Db.CreateDefaultDb()) {   var mql1=CustomersSet.Select(CustomersSet.CustomerName);   var join=mql1.LeftJoin(OrdersSet.SelectAll())    .ON(OrdersSet.CustomerId.Equal(CustomersSet.CustomerId).And(OrdersSet.OrderId.SmallerThan(1000)))    .Where(OrdersSet.OrderId.BiggerThan(1)).Top(10);   var sql=join.ToDebugSQL();//等价sql语句   var list=db.GetDictionaryList(join);   return list;  } } 

SELECT TOP 10 [Customers].[CustomerName],[Orders].* FROM  [Customers] LEFT JOIN [Orders] ON ( [Orders].[CustomerId]= [Customers].[CustomerId]  AND  [Orders].[OrderId]<@p1  ) WHERE   [Orders].[OrderId]>@p2  @p1=1000 @p2=1

3)多连接查询

  /// <summary> /// 测试三条jion的语句 /// </summary> public static DictionaryList TestHighJoinMQL(){  using (var db=Db.CreateDefaultDb()) {   var mql1=CustomersSet.Select(CustomersSet.CustomerName);   var doubleJoin=mql1.LeftJoin(OrdersSet.Select(OrdersSet.OrderId.AS("_OrderId")))    .ON(OrdersSet.CustomerId.Equal(CustomersSet.CustomerId).And(OrdersSet.OrderId.SmallerThan(100)))    ;   var threeJoin=doubleJoin.LeftJoin(OrderDetailsSet.SelectAll())    .ON(OrderDetailsSet.OrderId.Equal(OrdersSet.OrderId).And(OrderDetailsSet.OrderId.BiggerThan(2)))    .Where(OrdersSet.OrderId.SmallerThan(999)).Top(10);   var sql=threeJoin.ToDebugSQL();//等价sql语句   var list=db.GetDictionaryList(threeJoin);   return list;  } } 

SELECT TOP 10 * FROM (SELECT [Customers].[CustomerName],[Orders]. [OrderId] as "_OrderId" , [OrderDetails].*  FROM [Customers] LEFT JOIN  [Orders] ON ( [Orders].[CustomerId]=[Customers].[CustomerId]  AND   [Orders].[OrderId]<@p1  )  LEFT JOIN [OrderDetails] ON [OrderDetails]. [OrderId]=[Orders].[OrderId]  AND  [OrderDetails].[OrderId]>@p2   WHERE  [Orders].[OrderId]<@p3 ) TopTemp1  @p1=100 @p2=2 @p3=999

4)嵌套查询

  /// <summary> /// 嵌套查询 /// </summary> /// <returns></returns> public static DictionaryList QianTao(){  using (var db=Db.CreateDefaultDb()) {   var testBool=OrdersSet.SelectAll().Where(    OrdersSet.CustomerId.In(     CustomersSet.Select(CustomersSet.CustomerId).Where(CustomersSet.CustomerName.Contains("00"))    ).And(OrdersSet.OrderId.BiggerThan(8))   );   var sql=testBool.ToDebugSQL();//等价sql语句   return db.GetDictionaryList(testBool);  } } 

SELECT [Orders].* FROM [Orders] WHERE [Orders].[CustomerId] IN  (SELECT [Customers].[CustomerId] FROM [Customers] WHERE  [Customers].[CustomerName] LIKE @p1 )  AND  [Orders].[OrderId]>@p2  @p1=%00% @p2=8

5)Union查询

/// <summary> /// Union测试 /// </summary> /// <returns></returns> public static DictionaryList TestUnion(){  using (var db=Db.CreateDefaultDb()) {   var mql1=CustomersSet.SelectAll().Where(CustomersSet.CustomerId.BiggerThan(10));   var mql2=CustomersSet.SelectAll().Where(CustomersSet.CustomerId.SmallerThan(10));   var mql3=CustomersSet.SelectAll().Where(CustomersSet.CustomerId.Equal(10));   var mql=mql1.Union(mql2).Union(mql3).Top(1);   var sql=mql.ToDebugSQL();//等价sql语句   return db.GetDictionaryList(mql);  } } 

SELECT TOP 1 * FROM (SELECT [Customers].* FROM [Customers] WHERE   [Customers].[CustomerId]>@p1  UNION  SELECT [Customers].* FROM  [Customers] WHERE  [Customers].[CustomerId]<@p2  UNION  SELECT  [Customers].* FROM [Customers] WHERE [Customers]. [CustomerId]=@p3 ) TopTemp1  @p1=10 @p2=10 @p3=10
