使用的版本為SubSonic 3.0,測試的相關資料請看這篇。
下面就是以 SubSonic 去做 Insert / Select Top / Where In 的範例,如果有效率更好的寫法,麻煩請跟我說,感謝。
Insert
public static void SubSonicInsert(string name, int score) { Data.tbl_Speed_Test st= new Data.tbl_Speed_Test(); st.name = name; st.score = score; st.Save(); }語法超短的,相當於SQL Command的
insert into [Died_Test].[dbo].[tbl_Speed_Test] (name,score) values(@name,@score)SubSonic對有預設值的欄位也需要手動對ActiveRecord.cs(如果你是用ActiveRecord)改點設定,詳情可以見這篇"Linq to SQL, Entity Framework, SubSonic 3.0 對於預設欄位的處理方式"。
Select Top
public static void SubSonicSelectTop(int score) { var result = Data.tbl_Speed_Test.Find(x => x.score == score).Take(1); foreach (var item in result) { Console.WriteLine(item.guid + "\t" + item.name + "\t" + item.score); } }相當於SQL Command的
select top 1 * from [Died_Test].[dbo].[tbl_Speed_Test] where [score]=@score
Where In
public static void SubSonicSelectIn(int[] score) { List<Data.tbl_Speed_Test> result = new Data.Died_TestDB().Select.From<Data.tbl_Speed_Test>() .Where(Data.tbl_Speed_TestTable.scoreColumn).In(score).OrderAsc(Data.tbl_Speed_TestTable.scoreColumn).ExecuteTypedList<Data.tbl_Speed_Test>(); foreach (var item in result) { Console.WriteLine(item.guid + "\t" + item.name + "\t" + item.score); } }相當於SQL Command的
select * from [Died_Test].[dbo].[tbl_Speed_Test] where [score] in (@score1,@score2,@score3.....) order by [score]
