.NET 開源SqlServer ORM框架 SqlSugar 3.0 API

 

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 4.0+ MSSQL https://github.com/sunkaixuan/SqlSugar

 

ASP.NET CORE MSSQL https://github.com/sunkaixuan/ASP_NET_CORE_ORM_SqlSugar

 

ASP.NET 4.0+ MYSQL https://github.com/sunkaixuan/MySqlSugar

 

ASP.NET CORE MYSQL https://github.com/sunkaixuan/ASP_NET_CORE_ORM_MySqlSugar

 

ASP.NET 4.0+ Sqlite https://github.com/sunkaixuan/SqliteSugar

 

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();

                var c3 = db.Queryable<Student>().Where(c => c.name.EndsWith("a")).ToList();
                var c4 = db.Queryable<Student>().Where(c => !string.IsNullOrEmpty(c.name)).ToList();
                var c5 = db.Queryable<Student>().Where(c => c.name.Equals("小杰")).ToList();
                var c6 = db.Queryable<Student>().Where(c => c.name.Length > 4).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

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
