3.1.x ,將作為3.X系統的最後一個版本，下面將會開發 全新的功能
更新列表：https://github.com/sunkaixuan/SqlSugar/releases
優點：
SqlSugar 是一款小巧，並且功能齊全的ORM，並不需要像Dapper一樣依賴第三方擴充套件
SqlSugar 語法易用簡單 ，有漂亮的拉姆達語法，也支援Dapper SQL和ADO.NET的所有功能
SqlSugar 效能達到原生水準，遠超 Dapper和EF CORE。
SqlSugar 支援.NET CORE , 多個資料庫
SqlSugar 體積小巧只有150K是EF的30分之1 ，NUGET直接可以下載
特色功能
SqlbulkCopy和SqlbulkReplace 這兩個函式能夠處理海量資料插入和更新 ，也是眾多ORM沒有整合的功能之一
SQL日誌功能 可以方便的對SQL進行監控和寫入日誌
全域性過濾器 例如我都有IsDeleted來標識是否刪 除， 這樣我每查一個表就 要加一個WHERE條件 ，有了全域性過濾器就變成非常方便
T4+實體生成 可以自定義實體格式 並且可以能過T4模版快速生成實體檔案
POCO設計 實體類沒有任何屬性完全原生態
所有版本：

ASP.NET CORE Sqlite https://github.com/sunkaixuan/ASP_NET_CORE_ORM_MySqlSugar
ASP.NET 4.0+ ORACLE https://github.com/sunkaixuan/OracleSugar
連線資料庫
1.簡單用法
using(var db = new SqlSugarClient(ConnectionString)){
//use object
var list=db.Queryable<T>().ToList();
}
2.打包用法，推薦
/// <summary>
/// SqlSugar
/// </summary>
public class SugarDao
{
private SugarDao()
{
}
public static string ConnectionString
{
get
{
string reval = "server=.;uid=sa;pwd=sasa;database=SqlSugarTest";
return reval;
}
}
public static SqlSugarClient GetInstance()
{
var db = new SqlSugarClient(ConnectionString);
db.IsEnableLogEvent = true;//Enable log events
db.LogEventStarting = (sql, par) => { Console.WriteLine(sql + " " + par+"\r\n"); };
return db;
}
}
使用打包物件
using (var db = SugarDao.GetInstance())
{
var list=db.Queryable<T>().ToList();
}
3.高階玩法，基於IOC和指揮官模式的DEMO

1、使用拉姆達進行查詢
//查詢所有 var student = db.Queryable<Student>().ToList(); var studentDynamic = db.Queryable<Student>().ToDynamic(); var studentJson = db.Queryable<Student>().ToJson(); //查詢單條 var single = db.Queryable<Student>().Single(c => c.id == 1); //查詢單條根據主鍵 var singleByPk = db.Queryable<Student>().InSingle(1); //查詢單條沒有記錄返回空物件 var singleOrDefault = db.Queryable<Student>().SingleOrDefault(c => c.id == 11111111); //查詢單條沒有記錄返回空物件 var single2 = db.Queryable<Student>().Where(c => c.id == 1).SingleOrDefault(); //查詢第一條 var first = db.Queryable<Student>().Where(c => c.id == 1).First(); var first2 = db.Queryable<Student>().Where(c => c.id == 1).FirstOrDefault(); //取11-20條 var page1 = db.Queryable<Student>().Where(c => c.id > 10).OrderBy(it => it.id).Skip(10).Take(10).ToList(); //取11-20條 等於 Skip(pageIndex-1)*pageSize).Take(pageSize) 等於 between (pageIndex-1)*pageSize and pageIndex*pageSize var page2 = db.Queryable<Student>().Where(c => c.id > 10).OrderBy(it => it.id).ToPageList(2, 10); //查詢條數 var count = db.Queryable<Student>().Where(c => c.id > 10).Count(); //從第2條開始以後取所有 var skip = db.Queryable<Student>().Where(c => c.id > 10).OrderBy(it => it.id).Skip(2).ToList(); //取前2條 var take = db.Queryable<Student>().Where(c => c.id > 10).OrderBy(it => it.id).Take(2).ToList(); //Not like string conval = "a"; var notLike = db.Queryable<Student>().Where(c => !c.name.Contains(conval.ToString())).ToList(); //Like conval = "三"; var like = db.Queryable<Student>().Where(c => c.name.Contains(conval)).ToList(); //支援字串Where 讓你解決，更復雜的查詢 var student12 = db.Queryable<Student>().Where(c => "a" == "a").Where("id>@id", new { id = 1 }).ToList(); var student13 = db.Queryable<Student>().Where(c => "a" == "a").Where("id>100 and id in( select 1)").ToList(); //存在記錄反回true，則否返回false bool isAny100 = db.Queryable<Student>().Any(c => c.id == 100); bool isAny1 = db.Queryable<Student>().Any(c => c.id == 1); //獲取最大Id object maxId = db.Queryable<Student>().Max(it => it.id); int maxId1 = db.Queryable<Student>().Max(it => it.id).ObjToInt();//拉姆達 int maxId2 = db.Queryable<Student>().Max<int>("id"); //字串寫法 //獲取最小 int minId1 = db.Queryable<Student>().Where(c => c.id > 0).Min(it => it.id).ObjToInt();//拉姆達 int minId2 = db.Queryable<Student>().Where(c => c.id > 0).Min<int>("id");//字串寫法 //order By var orderList = db.Queryable<Student>().OrderBy("id desc,name asc").ToList();//字串支援多個排序 //可以多個order by表達示 var order2List = db.Queryable<Student>().OrderBy(it => it.name).OrderBy(it => it.id, OrderByType.desc).ToList(); // order by name as ,order by id desc //In var intArray = new[] { "5", "2", "3" }; var intList = intArray.ToList(); var listnew = db.Queryable<Student>().Where(it => intArray.Contains(it.name)).ToList(); var list0 = db.Queryable<Student>().In(it => it.id, 1, 2, 3).ToList(); var list1 = db.Queryable<Student>().In(it => it.id, intArray).ToList(); var list2 = db.Queryable<Student>().In("id", intArray).ToList(); var list3 = db.Queryable<Student>().In(it => it.id, intList).ToList(); var list4 = db.Queryable<Student>().In("id", intList).ToList(); var list6 = db.Queryable<Student>().In(intList).ToList();//不設定欄位預設主鍵 //分組查詢 var list7 = db.Queryable<Student>().Where(c => c.id < 20).GroupBy(it => it.sex).Select("sex,count(*) Count").ToDynamic(); var list8 = db.Queryable<Student>().Where(c => c.id < 20).GroupBy(it => it.sex).GroupBy(it => it.id).Select("id,sex,count(*) Count").ToDynamic(); List<StudentGroup> list9 = db.Queryable<Student>().Where(c => c.id < 20).GroupBy(it => it.sex).Select<StudentGroup>("Sex,count(*) Count").ToList(); List<StudentGroup> list10 = db.Queryable<Student>().Where(c => c.id < 20).GroupBy("sex").Select<StudentGroup>("Sex,count(*) Count").ToList(); //SELECT Sex,Count=count(*) FROM Student WHERE 1=1 AND (id < 20) GROUP BY Sex --生成結果 //2表關聯查詢 var jList = db.Queryable<Student>() .JoinTable<School>((s1, s2) => s1.sch_id == s2.id) //預設left join .Where<School>((s1, s2) => s1.id == 1) .Select("s1.*,s2.name as schName") .ToDynamic(); /*等於同於 SELECT s1.*,s2.name as schName FROM [Student] s1 LEFT JOIN [School] s2 ON s1.sch_id = s2.id WHERE s1.id = 1 */ //2表關聯查詢並分頁 var jList2 = db.Queryable<Student>() .JoinTable<School>((s1, s2) => s1.sch_id == s2.id) //預設left join //如果要用inner join這麼寫 //.JoinTable<School>((s1, s2) => s1.sch_id == s2.id ,JoinType.INNER) .Where<School>((s1, s2) => s1.id > 1) .OrderBy(s1 => s1.name) .Skip(10) .Take(20) .Select("s1.*,s2.name as schName") .ToDynamic();

//上面的方式都是與第一張表join，第三張表想與第二張表join寫法如下 List<V_Student> jList4 = db.Queryable<Student>() .JoinTable<School>((s1, s2) => s1.sch_id == s2.id) // left join School s2 on s1.id=s2.id .JoinTable<School, Area>((s1, s2, a1) => a1.id == s2.AreaId)// left join Area a1 on a1.id=s2.AreaId 第三張表與第二張表關聯 .JoinTable<Area, School>((s1, a1, s3) => a1.id == s3.AreaId)// left join School s3 on a1.id=s3.AreaId 第四第表第三張表關聯 .JoinTable<School>((s1, s4) => s1.sch_id == s4.id) // left join School s2 on s1.id=s4.id .Select<School, Area, V_Student>((s1, s2, a1) => new V_Student { id = s1.id, name = s1.name, SchoolName = s2.name, AreaName = a1.name }).ToList(); //等同於 //SELECT id = s1.id, name = s1.name, SchoolName = s2.name, AreaName = a1.name //FROM [Student] s1 //LEFT JOIN School s2 ON ( s1.sch_id = s2.id ) //LEFT JOIN Area a1 ON ( a1.id = s2.AreaId ) //第三張表與第二張表關聯 //LEFT JOIN School s3 ON ( a1.id = s3.AreaId ) //第四張表與第三張表關聯 //LEFT JOIN School s4 ON ( s1.sch_id = s4.id ) //WHERE 1=1 //Join子查詢語句加分頁的寫法 var childQuery = db.Queryable<Area>().Where("id=@id").Select(it => new { id = it.id }).ToSql();//建立子查詢SQL string childTableName =SqlSugarTool.PackagingSQL(childQuery.Key);//將SQL語句用()包成表 var queryable = db.Queryable<Student>() .JoinTable<School>((s1, s2) => s1.sch_id == s2.id) //LEFT JOIN School s2 ON ( s1.sch_id = s2.id ) .JoinTable(childTableName, "a1", "a1.id=s2.areaid", new { id = 1 }, JoinType.INNER) //INNER JOIN (SELECT * FROM [Area] WHERE 1=1 AND id=@id ) a1 ON a1.id=s2.areaid .OrderBy(s1 => s1.id); var list = queryable.Select<School, Area, V_Student>((s1, s2, a1) => new V_Student { id = s1.id, name = s1.name, SchoolName = s2.name, AreaName = a1.name }) .ToPageList(0, 200); var count2 = queryable.Count(); //拼接例子 var queryable2 = db.Queryable<Student>().Where(it => true); if (maxId.ObjToInt() == 1) { queryable2.Where(it => it.id == 1); } else { queryable2.Where(it => it.id == 2); } var listJoin = queryable2.ToList(); //queryable和SqlSugarClient解耦 var par = new Queryable<Student>().Where(it => it.id == 1);//聲名沒有connection物件的Queryable par.DB = db; var listPar = par.ToList(); //檢視生成的sql和引數 var id = 1; var sqlAndPars = db.Queryable<Student>().Where(it => it.id == id).OrderBy(it => it.id).ToSql(); //拉姆達支援的函式操作 var par1 = "2015-1-1"; var par2 = " 我 有空格A, "; var r1 = db.Queryable<Student>().Where(it => it.name == par1.ObjToString()).ToList(); //ObjToString會將null轉轉成"" var r2 = db.Queryable<InsertTest>().Where(it => it.d1 == par1.ObjToDate()).ToList(); var r3 = db.Queryable<InsertTest>().Where(it => it.id == 1.ObjToInt()).ToList();//ObjToInt會將null轉轉成0 var r4 = db.Queryable<InsertTest>().Where(it => it.id == 2.ObjToDecimal()).ToList(); var r5 = db.Queryable<InsertTest>().Where(it => it.id == 3.ObjToMoney()).ToList(); var r6 = db.Queryable<InsertTest>().Where(it => it.v1 == par2.Trim()).ToList(); var convert1 = db.Queryable<Student>().Where(c => c.name == "a".ToString()).ToList(); var convert2 = db.Queryable<Student>().Where(c => c.id == Convert.ToInt32("1")).ToList(); var convert3 = db.Queryable<Student>().Where(c => c.name == par2.ToLower()).ToList(); var convert4 = db.Queryable<Student>().Where(c => c.name == par2.ToUpper()).ToList(); var convert5= db.Queryable<Student>().Where(c => DateTime.Now > Convert.ToDateTime("2015-1-1")).ToList(); var c1 = db.Queryable<Student>().Where(c => c.name.Contains("a")).ToList(); var c2 = db.Queryable<Student>().Where(c => c.name.StartsWith("a")).ToList(); var c3 = db.Queryable<Student>().Where(c => c.name.EndsWith("a")).ToList();

var time = db.Queryable<InsertTest>().Where(c => c.d1>DateTime.Now.AddDays(1)).ToList(); var time2 = db.Queryable<InsertTest>().Where(c => c.d1 > DateTime.Now.AddYears(1)).ToList(); var time3 = db.Queryable<InsertTest>().Where(c => c.d1 > DateTime.Now.AddMonths(1)).ToList();
2、使用原生SQL查詢
//轉成list List<Student> list1 = db.SqlQuery<Student>("select * from Student"); //轉成list帶參 List<Student> list2 = db.SqlQuery<Student>("select * from Student where id=@id", new { id = 1 }); //轉成dynamic dynamic list3 = db.SqlQueryDynamic("select * from student"); //轉成json string list4 = db.SqlQueryJson("select * from student"); //返回int var list5 = db.SqlQuery<int>("select top 1 id from Student").SingleOrDefault(); //反回鍵值 Dictionary<string, string> list6 = db.SqlQuery<KeyValuePair<string, string>>("select id,name from Student").ToDictionary(it => it.Key, it => it.Value); //反回List<string[]> var list7 = db.SqlQuery<string[]>("select top 1 id,name from Student").SingleOrDefault(); //儲存過程 var spResult = db.SqlQuery<School>("exec sp_school @p1,@p2", new { p1 = 1, p2 = 2 }); //儲存過程加Output var pars = SqlSugarTool.GetParameters(new { p1 = 1,p2=0 }); //將匿名物件轉成SqlParameter db.IsClearParameters = false;//禁止清除引數 pars[1].Direction = ParameterDirection.Output; //將p2設為 output var spResult2 = db.SqlQuery<School>("exec sp_school @p1,@p2 output", pars); db.IsClearParameters = true;//啟動請動清除引數 var outPutValue = pars[1].Value;//獲取output @p2的值 //獲取第一行第一列的值 string v1 = db.GetString("select '張三' as name"); int v2 = db.GetInt("select 1 as name"); double v3 = db.GetDouble("select 1 as name"); decimal v4 = db.GetDecimal("select 1 as name");
3、SQL高階拼接器寫法
using (var db = SugarDao.GetInstance()) { //---------Sqlable,建立多表查詢---------// //多表查詢 List<School> dataList = db.Sqlable() .From("school", "s") .Join("student", "st", "st.id", "s.id", JoinType.INNER) .Join("student", "st2", "st2.id", "st.id", JoinType.LEFT) .Where("s.id>100 and s.id<@id") .Where("1=1")//可以多個WHERE .OrderBy("id") .SelectToList<School/*新的Model我這裡沒有所以寫的School*/>("st.*", new { id = 1 }); //多表分頁 List<School> dataPageList = db.Sqlable() .From("school", "s") .Join("student", "st", "st.id", "s.id", JoinType.INNER) .Join("student", "st2", "st2.id", "st.id", JoinType.LEFT) .Where("s.id>100 and s.id<100") .SelectToPageList<School>("st.*", "s.id", 1, 10); //多表分頁WHERE加子查詢 List<School> dataPageList2 = db.Sqlable() .From("school", "s") .Join("student", "st", "st.id", "s.id", JoinType.INNER) .Join("student", "st2", "st2.id", "st.id", JoinType.LEFT) .Where("s.id>100 and s.id<100 and s.id in (select 1 )" /*這裡面寫子查詢都可以*/) .SelectToPageList<School>("st.*", "s.id", 1, 10); //--------轉成List Dynmaic 或者 Json-----// //不分頁 var list1 = db.Sqlable().From("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=@id", JoinType.INNER).SelectToDynamic("*", new { id = 1 }); var list2 = db.Sqlable().From("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=@id", JoinType.INNER).SelectToJson("*", new { id = 1 }); var list3 = db.Sqlable().From("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=@id", JoinType.INNER).SelectToDataTable("*", new { id = 1 }); //分頁 var list4 = db.Sqlable().From("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=@id", JoinType.INNER).SelectToPageDynamic("s.*", "l.id", 1, 10, new { id = 1 }); var list5 = db.Sqlable().From("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=@id", JoinType.INNER).SelectToPageTable("s.*", "l.id", 1, 10, new { id = 1 }); var list6 = db.Sqlable().From("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=@id", JoinType.INNER).SelectToPageDynamic("s.*", "l.id", 1, 10, new { id = 1 }); //--------拼接-----// Sqlable sable = db.Sqlable().From<Student>("s").Join<School>("l", "s.sch_id", "l.id", JoinType.INNER); string name = "a"; int id = 1; if (!string.IsNullOrEmpty(name)) { sable = sable.Where("s.name=@name"); } if (!string.IsNullOrEmpty(name)) { sable = sable.Where("s.id=@id or s.id=100"); } if (id > 0) { sable = sable.Where("l.id in (select top 10 id from school)");//where加子查詢 } var pars = new { id = id, name = name }; int pageCount = sable.Count(pars); var list7 = sable.SelectToPageList<Student>("s.*", "l.id desc", 1, 20, pars); }
4、更新
//指定列更新 db.Update<School>(new { name = "藍翔14" }, it => it.id == 14); //只更新name列 db.Update<School, int>(new { name = "藍翔11 23 12", areaId = 2 }, 11, 23, 12); db.Update<School, string>(new { name = "藍翔2" }, new string[] { "11", "21" }); db.Update<School>(new { name = "藍翔2" }, it => it.id == 100); //支援字典更新，適合動態許可權 var dic = new Dictionary<string, string>(); dic.Add("name", "第十三條"); dic.Add("areaId", "1"); db.Update<School, int>(dic, 13); //整個實體更新 db.Update(new School { id = 16, name = "藍翔16", AreaId = 1 }); db.Update<School>(new School { id = 12, name = "藍翔12", AreaId = 2 }, it => it.id == 18); db.Update<School>(new School() { id = 11, name = "青鳥11" }); //設定不更新列 db.DisableUpdateColumns = new string[] { "CreateTime" };//設定CreateTime不更新 TestUpdateColumns updObj = new TestUpdateColumns() { VGUID = Guid.Parse("542b5a27-6984-47c7-a8ee-359e483c8470"), Name = "xx", Name2 = "xx2", IdentityField = 0, CreateTime = null }; //CreateTime將不會被更新 db.Update(updObj); //以前實現這種更新需要用指定列的方式實現，現在就簡單多了。 //批量更新 資料量小時建議使用 var updateResult = db.UpdateRange(GetUpdateList()); //批量更新 資料量大時建議使用 var updateResult2 = db.SqlBulkReplace(GetUpdateList2());
5、刪除和狀態刪除
//刪除 db.Delete<School, int>(10); db.Delete<School>(it => it.id > 100); //主鍵批量刪除 db.Delete<School, string>(new string[] { "100", "101", "102" }); //非主鍵批量刪除 db.Delete<School, string>(it => it.name, new string[] { "" }); db.Delete<School, int>(it => it.id, new int[] { 20, 22 }); //假刪除 //db.FalseDelete<school>("is_del", 100); //等同於 update school set is_del=1 where id in(100) //db.FalseDelete<school>("is_del", it=>it.id==100);
6、插入
db.Insert(GetInsertItem()); //插入一條記錄 (有主鍵也好，沒主鍵也好，有自增列也好都可以插進去) db.InsertRange(GetInsertList()); //批量插入 支援（別名表等功能） db.SqlBulkCopy(GetInsertList()); //批量插入 適合海量資料插入，要求實體與資料庫一致，不支援(別名表、排除列等功能) //設定不插入列 db.DisableInsertColumns = new string[] { "sex" };//sex列將不會插入值 Student s = new Student() { name = "張" + new Random().Next(1, int.MaxValue), sex = "gril" }; var id = db.Insert(s); //插入 //查詢剛插入的sex是否有值 var sex = db.Queryable<Student>().Single(it => it.id == id.ObjToInt()).sex;//無值 var name = db.Queryable<Student>().Single(it => it.id == id.ObjToInt()).name;//有值
7、列舉支援
var stuList = db.Queryable<Student>().ToList(); db.Insert<Student>(new Student() { sch_id = SchoolEnum.北大青鳥 }); db.Update<Student>(new Student() { sch_id = SchoolEnum.it清華, id = 11 }); var stuList2 = db.Queryable<Student>().Where(it => it.sch_id == SchoolEnum.全智).ToList();
8、實體生成加T4
//可以結合別名表，請看別名表的用法 //db.SetMappingTables(mappingTableList); db.ClassGenerating.CreateClassFiles(db, ("e:/TestModels"), "Models"); //只生成student和school表的實體 db.ClassGenerating.CreateClassFilesByTableNames(db, "e:/TestModels2", "Models", new string[] { "student", "school" }); //根據表名生成class字串 var str = db.ClassGenerating.TableNameToClass(db, "Student"); var dynamicToClassStr = db.ClassGenerating.DynamicToClass(new { id = 1 }, "dyName"); //根據SQL語句生成class字串 var str2 = db.ClassGenerating.SqlToClass(db, "select top 1 * from Student", "student"); //改變值（lassTemplate.ItemTemplate=XXXX）可以自定義格式 var tempItem = ClassTemplate.ItemTemplate;//例如可以在生成的實體新增預設建構函式給指定的欄位賦預設值或者公司資訊等 var temp = ClassTemplate.Template; //設定新格式模板 //主鍵Guid.New(), //CreateTime為DateTime.Now //IsRemove=0 //UpdateTime為DateTime.Now ClassTemplate.Template = "using System;\r\nusing System.Linq;\r\nusing System.Text;\r\n\r\nnamespace $namespace\r\n{\r\n public class $className\r\n {\r\n public $className() \r\n { \r\n this.CreateTime = DateTime.Now;\r\n this. = 0;\r\n this.UpdateTime=DateTime.Now;\r\n this.$primaryKeyName=Guid.NewGuid().ToString(\"N\").ToUpper();\r\n }\r\n $foreach\r\n }\r\n}\r\n"; //新格式的實體字串 var str3 = db.ClassGenerating.TableNameToClass(db, "Student");
使用T4
詳細教程：
http://www.cnblogs.com/sunkaixuan/p/5751503.html
9、ADO.NET
var r1 = db.GetDataTable("select * from student"); var r2 = db.GetSingle<Student>("select top 1 * from student"); var r3 = db.GetScalar("select count(1) from student"); var r4 = db.GetReader("select count(1) from student"); r4.Dispose(); var r5 = db.GetString("select top 1 name from student"); var r6 = db.ExecuteCommand("select 1"); //引數支援 var p1 = db.GetDataTable("select * from student where id=@id", new {id=1 }); var p2 = db.GetDataTable("select * from student where id=@id", new Dictionary<string, object>() { { "id", "1" } });//目前只支援 Dictionary<string, object>和Dictionary<string, string> var p3 = db.GetDataTable("select * from student where id=@id", new SqlParameter("@id",1) );
10、日誌記錄功能
//日誌記錄功能 public class Log : IDemos { public void Init() { Console.WriteLine("啟動Log.Init"); using (var db = SugarDemoDao.GetInstance()) { var a1 = db.Queryable<Student>().Where(it => it.id == 1).ToList(); var a2 = db.Queryable<Student>().OrderBy(it => it.id).ToList(); } } public class SugarConfigs { public static Action<string, string> LogEventStarting = (sql, pars) => { Console.WriteLine("starting:" + sql + " " + pars); using (var db = SugarDemoDao.GetInstance()) { //日誌記錄件事件裡面用到資料庫操作 IsEnableLogEvent一定要為false否則將引起死迴圈，並且要新開一個資料例項 像我這樣寫就沒問題。 db.IsEnableLogEvent = false; db.ExecuteCommand("select 1"); } }; public static Action<string, string> LogEventCompleted = (sql, pars) => { Console.WriteLine("completed:" + sql + " " + pars); }; } /// <summary> /// SqlSugar /// </summary> public class SugarDemoDao { public static SqlSugarClient GetInstance() { var db = new SqlSugarClient(SugarDao.ConnectionString); db.IsEnableLogEvent = true;//啟用日誌事件 db.LogEventStarting = SugarConfigs.LogEventStarting; db.LogEventCompleted = SugarConfigs.LogEventCompleted; return db; } } } }
11、別名表功能
using System; using System.Collections.Generic; using System.Linq; using System.Text; using NewTest.Dao; using Models; using System.Data.SqlClient; using SqlSugar; namespace NewTest.Demos { //別名表的功能 public class MappingTable : IDemos { public void Init() { Console.WriteLine("啟動MappingTable.Init"); //單個設定 using (var db = SugarDao.GetInstance()) { var list = db.Queryable<V_Student>("Student").ToList();//查詢的是 select * from student 而我的實體名稱為V_Student } //全域性設定 using (var db = SugarFactory.GetInstance()) { var list = db.Queryable<V_Student>().ToList();//查詢的是 select * from student 而我的實體名稱為V_Student } } /// <summary> /// 全域性配置類 /// </summary> public class SugarConfigs { //key類名 value表名 public static List<KeyValue> MpList = new List<KeyValue>(){ new KeyValue(){ Key="FormAttr", Value="Flow_FormAttr"}, new KeyValue(){ Key="Student3", Value="Student"}, new KeyValue(){ Key="V_Student", Value="Student"} }; } /// <summary> /// SqlSugar例項工廠 /// </summary> public class SugarFactory { //禁止例項化 private SugarFactory() { } public static SqlSugarClient GetInstance() { string connection = SugarDao.ConnectionString; //這裡可以動態根據cookies或session實現多庫切換 var db = new SqlSugarClient(connection); db.SetMappingTables(SugarConfigs.MpList);//設定關聯表 (引用地址賦值，每次賦值都只是儲存一個記憶體地址) return db; } } } }
12別名列功能
using System; using System.Collections.Generic; using System.Linq; using System.Text; using NewTest.Dao; using System.Data.SqlClient; using SqlSugar; namespace NewTest.Demos { //別名列的功能 public class MappingColumns : IDemos { public void Init() { Console.WriteLine("啟動MappingColumns.Init"); //全域性設定 using (var db = SugarFactory.GetInstance()) { var list = db.Queryable<Student>().Where(it=>it.classId==1).ToList(); } } public class Student { //id public int classId { get; set; } //name public string className { get; set; } //sch_id public int classSchoolId { get; set; } public int isOk { get; set; } } /// <summary> /// 全域性配置別名列（不區分表） /// </summary> public class SugarConfigs { //key實體欄位名 value表欄位名 ，KEY唯一否則異常 public static List<KeyValue> MpList = new List<KeyValue>(){ new KeyValue(){ Key="classId", Value="id"}, new KeyValue(){ Key="className", Value="name"}, new KeyValue(){ Key="classSchoolId", Value="sch_id"} }; } /// <summary> /// SqlSugar例項工廠 /// </summary> public class SugarFactory { //禁止例項化 private SugarFactory() { } public static SqlSugarClient GetInstance() { string connection = SugarDao.ConnectionString; //這裡可以動態根據cookies或session實現多庫切換 var db = new SqlSugarClient(connection); //注意：只有啟動屬性對映才可以使用SetMappingColumns db.IsEnableAttributeMapping = true; db.SetMappingColumns(SugarConfigs.MpList);//設定關聯列 (引用地址賦值，每次賦值都只是儲存一個記憶體地址) return db; } } } }
13通過屬性來設定別名表和別名列
using System; using System.Collections.Generic; using System.Linq; using System.Text; using NewTest.Dao; using Models; using System.Data.SqlClient; using SqlSugar; namespace NewTest.Demos { //通過屬性的方法設定別名表和別名欄位（主鍵和自添列都無需設定 SQLSUGAR會幫你自動處理） //注意:【屬性對映和 (SetMappingTables、SetMappingColumns)方式對映 2種選其中一，不清楚底層快取機質不建議同時使用】 public class AttributesMapping : IDemos { public void Init() { Console.WriteLine("啟動AttributesMapping.Init"); using (var db = DBManager.GetInstance()) { //查詢 var list = db.Queryable<TestStudent>() .Where(it => it.className.Contains("小")).OrderBy(it => it.classSchoolId).Select<V_Student>(it => new V_Student() { id = it.classId, name = it.className }).ToList(); var list2 = db.Queryable<TestStudent>() .JoinTable<TestSchool>((s1, s2) => s1.classSchoolId == s2.classId) .OrderBy<TestSchool>((s1, s2) => s1.classId) .Select<TestStudent, TestSchool, V_Student>((s1, s2) => new V_Student() { id = s1.classId, name = s1.className, SchoolName = s2.className }).ToList(); //新增 TestStudent s = new TestStudent(); s.className = "屬性名"; s.classSchoolId = 1; var id = db.Insert(s); s.classId = id.ObjToInt(); //更新 db.Update(s); db.Update<TestStudent, int>(s, 100); db.Update<TestStudent>(s, it => it.classId == 100); db.SqlBulkReplace(new List<TestStudent>() { s }); //刪除 db.Delete<TestStudent>(it => it.classId == 100); } } /// <summary> /// 屬性只作為初始化對映，SetMappingTables和SetMappingColumns可以覆蓋 /// </summary> [SugarMapping(TableName = "Student")] public class TestStudent { [SugarMapping(ColumnName = "id")] public int classId { get; set; } [SugarMapping(ColumnName = "name")] public string className { get; set; } [SugarMapping(ColumnName = "sch_id")] public int classSchoolId { get; set; } public int isOk { get; set; } /// <summary> /// 資料庫並沒有這一列 /// </summary> public string errorField { get; set; } } [SugarMapping(TableName = "School")] public class TestSchool { [SugarMapping(ColumnName = "id")] public int classId { get; set; } [SugarMapping(ColumnName = "name")] public string className { get; set; } public int AreaId = 1; } } public class DBManager { public static SqlSugarClient GetInstance() { var db = new SqlSugarClient(SugarDao.ConnectionString); db.IsEnableAttributeMapping = true;//啟用屬性對映 db.IsIgnoreErrorColumns = true;//忽略非資料庫列 db.IsEnableLogEvent = true;//啟用日誌事件 db.LogEventStarting = (sql, par) => { Console.WriteLine(sql + " " + par + "\r\n"); }; return db; } } }
14、行列過濾 (行過濾器可以設定多個，以逗號隔開)
using System; using System.Collections.Generic; using System.Linq; using System.Text; using NewTest.Dao; using Models; using System.Data.SqlClient; using SqlSugar; namespace NewTest.Demos { //行過濾加列過濾 //許可權管理的最佳設計 public class Filter2 : IDemos { public void Init() { Console.WriteLine("啟動Filter2.Init"); using (SqlSugarClient db = SugarDaoFilter.GetInstance())//開啟資料庫連線 { //設定走哪個過濾器 db.CurrentFilterKey = "role1"; //queryable var list = db.Queryable<Student>().ToJson(); //where id=1 , 可以檢視id和name //設定走哪個過濾器 db.CurrentFilterKey = "role2"; //queryable var list2 = db.Queryable<Student>().ToJson(); //where id=2 , 可以檢視name } } /// <summary> /// 擴充套件SqlSugarClient /// </summary> public class SugarDaoFilter { //禁止例項化 private SugarDaoFilter() { } /// <summary> /// 頁面所需要的過濾行 /// </summary> private static Dictionary<string, Func<KeyValueObj>> _filterParas = new Dictionary<string, Func<KeyValueObj>>() { { "role1",()=>{ return new KeyValueObj(){ Key=" id=@id" , Value=new{ id=1}}; } }, { "role2",()=>{ return new KeyValueObj() { Key = " id=@id", Value = new { id = 2 } }; } }, }; /// <summary> /// 頁面所需要的過濾列 /// </summary> private static Dictionary<string, List<string>> _filterColumns = new Dictionary<string, List<string>>() { { "role1",new List<string>(){"id","name"} }, { "role2",new List<string>(){"name"} }, }; public static SqlSugarClient GetInstance() { string connection = SugarDao.ConnectionString; //這裡可以動態根據cookies或session實現多庫切換 var reval = new SqlSugarClient(connection); //支援sqlable和queryable reval.SetFilterFilterParas(_filterParas); //列過濾只支援queryable reval.SetFilterFilterParas(_filterColumns); return reval; } } } }
15、自動排除非資料庫列
//排除錯誤列 public class IgnoreErrorColumns : IDemos { public void Init() { Console.WriteLine("啟動IgnoreErrorColumns.Init"); using (var db = SugarDao.GetInstance()) { db.IsIgnoreErrorColumns = true; //Student表並沒有 AreaName var id= db.Insert<STUDENT>(new STUDENT() { name = "張三", AreaName = "北大" }); db.Update<STUDENT>(new STUDENT() { id=id.ObjToInt() ,name = "張三2", AreaName = "北大" }); } } public class STUDENT { /// <summary> /// Desc:- /// Default:- /// Nullable:False /// </summary> public int id { get; set; } /// <summary> /// Desc:- /// Default:- /// Nullable:True /// </summary> public string name { get; set; } /// <summary> /// Desc:學校ID /// Default:- /// Nullable:True /// </summary> public int? sch_id { get; set; } /// <summary> /// Desc:- /// Default:- /// Nullable:True /// </summary> public string sex { get; set; } /// <summary> /// Desc:- /// Default:- /// Nullable:True /// </summary> public Boolean? isOk { get; set; } public string SchoolName { get; set; } public string AreaName { get; set; } public string SubjectName { get; set; } } }
16、事務
using System; using System.Collections.Generic; using System.Linq; using System.Text; using NewTest.Dao; using Models; using System.Data.SqlClient; using SqlSugar; namespace NewTest.Demos { //事務 public class Tran : IDemos { public void Init() { Console.WriteLine("啟動Tran.Init"); using (SqlSugarClient db = SugarDao.GetInstance())//開啟資料庫連線 { db.IsNoLock = true;//啟用無鎖查詢 db.CommandTimeOut = 30000;//設定超時時間 try { db.BeginTran();//開啟事務 //db.BeginTran(IsolationLevel.ReadCommitted);+3過載可以設定事世隔離級別 db.CommitTran();//提交事務 } catch (Exception) { db.RollbackTran();//回滾事務 throw; } } } } }
17、流水號功能
using System; using System.Collections.Generic; using System.Linq; using System.Text; using NewTest.Dao; using Models; using System.Data.SqlClient; using SqlSugar; namespace NewTest.Demos { //流水號的功能 public class SerialNumber : IDemos { public void Init() { Console.WriteLine("啟動SerialNumber.Init"); using (SqlSugarClient db = SugarFactory.GetInstance())//開啟資料庫連線 { var dientityValue = db.Insert<Student>(new Student() { }); var name = db.Queryable<Student>().Single(it => it.id == dientityValue.ObjToInt()).name; Console.WriteLine(name); var dientityValue2 = db.Insert<School>(new School() { }); var name2 = db.Queryable<School>().Single(it => it.id == dientityValue2.ObjToInt()).name; Console.WriteLine(name2); ; } } /// <summary> /// 全域性配置類 /// </summary> public class SugarConfigs { public static List<PubModel.SerialNumber> NumList = new List<PubModel.SerialNumber>(){ new PubModel.SerialNumber(){TableName="Student", FieldName="name", GetNumFunc=()=>{ //GetNumFunc在沒有事中使用 return "stud-"+DateTime.Now.ToString("yyyy-MM-dd"); }}, new PubModel.SerialNumber(){TableName="School", FieldName="name", GetNumFuncWithDb=db=>{ //事務中請使用GetNumFuncWithDb保證同一個DB物件,不然會出現死鎖 return "ch-"+DateTime.Now.ToString("syyyy-MM-dd"); }} }; } /// <summary> /// SqlSugar例項工廠 /// </summary> public class SugarFactory { //禁止例項化 private SugarFactory() { } public static SqlSugarClient GetInstance() { string connection = SugarDao.ConnectionString; //這裡可以動態根據cookies或session實現多庫切換 var db = new SqlSugarClient(connection); db.SetSerialNumber(SugarConfigs.NumList);//設定流水號 return db; } } } }
18、多庫平行計算功能
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using SqlSugar; using System.Configuration; using System.Data; using System.Threading.Tasks; using System.Transactions; using System.Threading; namespace WebTest.Demo { /// <summary> /// /*******************************************************************分散式計算 demo**************************************************************/ /// </summary> public partial class Cloud : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { var id = Guid.Parse("4FC950EC-7C23-480F-9545-443EBDCA32E9");
