.NET 开源SqlServer ORM框架 SqlSugar 3.0 API

 

3.1.x ,将作为3.X系统的最后一个版本，下面将会开发 全新的功能

更新列表：https://github.com/sunkaixuan/SqlSugar/releases

 

优点：

 

SqlSugar 是一款小巧，并且功能齐全的ORM，并不需要像Dapper一样依赖第三方扩展

 

SqlSugar 语法易用简单 ，有漂亮的拉姆达语法，也支持Dapper SQL和ADO.NET的所有功能

 

SqlSugar 性能达到原生水准，远超 Dapper和EF CORE。

 

SqlSugar 支持.NET CORE , 多个数据库

 

SqlSugar 体积小巧只有150K是EF的30分之1 ，NUGET直接可以下载

 

 

 

特色功能

 

SqlbulkCopy和SqlbulkReplace 这两个函数能够处理海量数据插入和更新 ，也是众多ORM没有集成的功能之一 

 

SQL日志功能 可以方便的对SQL进行监控和写入日志

 

全局过滤器  例如我都有IsDeleted来标识是否删 除， 这样我每查一个表就 要加一个WHERE条件 ，有了全局过滤器就变成非常方便

 

T4+实体生成 可以自定义实体格式 并且可以能过T4模版快速生成实体文件

 

POCO设计   实体类没有任何属性完全原生态

 

 

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

  

连接数据库

 

1.简单用法

 

using(var db = new SqlSugarClient(ConnectionString)){

    //use object
    var list=db.Queryable().ToList();

}

 

 

2.打包用法，推荐

 

/// 

/// SqlSugar
/// 
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; } }

 

使用打包对象

 

using (var db = SugarDao.GetInstance())
{
    var list=db.Queryable().ToList();
}

 

 

 

3.高级玩法，基于IOC和指挥官模式的DEMO

1、使用拉姆达进行查询

                //查询所有
                var student = db.Queryable().ToList();
                var studentDynamic = db.Queryable().ToDynamic();
                var studentJson = db.Queryable().ToJson();


                //查询单条
                var single = db.Queryable().Single(c => c.id == 1);
                //查询单条根据主键
                var singleByPk = db.Queryable().InSingle(1);
                //查询单条没有记录返回空对象
                var singleOrDefault = db.Queryable().SingleOrDefault(c => c.id == 11111111);
                //查询单条没有记录返回空对象
                var single2 = db.Queryable().Where(c => c.id == 1).SingleOrDefault();

                //查询第一条
                var first = db.Queryable().Where(c => c.id == 1).First();
                var first2 = db.Queryable().Where(c => c.id == 1).FirstOrDefault();

                //取11-20条
                var page1 = db.Queryable().Where(c => c.id > 10).OrderBy(it => it.id).Skip(10).Take(10).ToList();

                //取11-20条  等于 Skip(pageIndex-1)*pageSize).Take(pageSize) 等于  between (pageIndex-1)*pageSize and  pageIndex*pageSize
                var page2 = db.Queryable().Where(c => c.id > 10).OrderBy(it => it.id).ToPageList(2, 10);

                //查询条数
                var count = db.Queryable().Where(c => c.id > 10).Count();

                //从第2条开始以后取所有
                var skip = db.Queryable().Where(c => c.id > 10).OrderBy(it => it.id).Skip(2).ToList();

                //取前2条
                var take = db.Queryable().Where(c => c.id > 10).OrderBy(it => it.id).Take(2).ToList();

                //Not like 
                string conval = "a";
                var notLike = db.Queryable().Where(c => !c.name.Contains(conval.ToString())).ToList();

                //Like
                conval = "三";
                var like = db.Queryable().Where(c => c.name.Contains(conval)).ToList();

                //支持字符串Where 让你解决，更复杂的查询
                var student12 = db.Queryable().Where(c => "a" == "a").Where("id>@id", new { id = 1 }).ToList();
                var student13 = db.Queryable().Where(c => "a" == "a").Where("id>100 and id in( select 1)").ToList();


                //存在记录反回true，则否返回false
                bool isAny100 = db.Queryable().Any(c => c.id == 100);
                bool isAny1 = db.Queryable().Any(c => c.id == 1);


                //获取最大Id
                object maxId = db.Queryable().Max(it => it.id);
                int maxId1 = db.Queryable().Max(it => it.id).ObjToInt();//拉姆达
                int maxId2 = db.Queryable().Max<int>("id"); //字符串写法

                //获取最小
                int minId1 = db.Queryable().Where(c => c.id > 0).Min(it => it.id).ObjToInt();//拉姆达
                int minId2 = db.Queryable().Where(c => c.id > 0).Min<int>("id");//字符串写法


                //order By 
                var orderList = db.Queryable().OrderBy("id desc,name asc").ToList();//字符串支持多个排序
                //可以多个order by表达示
                var order2List = db.Queryable().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().Where(it => intArray.Contains(it.name)).ToList();
                var list0 = db.Queryable().In(it => it.id, 1, 2, 3).ToList();
                var list1 = db.Queryable().In(it => it.id, intArray).ToList();
                var list2 = db.Queryable().In("id", intArray).ToList();
                var list3 = db.Queryable().In(it => it.id, intList).ToList();
                var list4 = db.Queryable().In("id", intList).ToList();
                var list6 = db.Queryable().In(intList).ToList();//不设置字段默认主键

                //分组查询
                var list7 = db.Queryable().Where(c => c.id < 20).GroupBy(it => it.sex).Select("sex,count(*) Count").ToDynamic();
                var list8 = db.Queryable().Where(c => c.id < 20).GroupBy(it => it.sex).GroupBy(it => it.id).Select("id,sex,count(*) Count").ToDynamic();
                List list9 = db.Queryable().Where(c => c.id < 20).GroupBy(it => it.sex).Select("Sex,count(*) Count").ToList();
                List list10 = db.Queryable().Where(c => c.id < 20).GroupBy("sex").Select("Sex,count(*) Count").ToList();
                //SELECT Sex,Count=count(*)  FROM Student  WHERE 1=1  AND  (id < 20)    GROUP BY Sex --生成结果

                var time3 = db.Queryable().Where(c => c.d1 > DateTime.Now.AddMonths(1)).ToList();

 

2、使用原生SQL查询

                //转成list
                List list1 = db.SqlQuery("select * from Student");
                //转成list带参
                List list2 = db.SqlQuery("select * from Student where id=@id", new { id = 1 });
                //转成dynamic
                dynamic list3 = db.SqlQueryDynamic("select * from student");
                //转成json
                string list4 = db.SqlQueryJson("select * from student");
                //返回int
                var list5 = db.SqlQuery<int>("select top 1 id from Student").SingleOrDefault();
                //反回键值
                Dictionary<string, string> list6 = db.SqlQuerystring, string>>("select id,name from Student").ToDictionary(it => it.Key, it => it.Value);
                //反回List
                var list7 = db.SqlQuery<string[]>("select top 1 id,name from Student").SingleOrDefault();
                //存储过程
                var spResult = db.SqlQuery("exec sp_school @p1,@p2", new { p1 = 1, p2 = 2 });

                //存储过程加Output 
                var pars = SqlSugarTool.GetParameters(new { p1 = 1,p2=0 }); //将匿名对象转成SqlParameter
                db.IsClearParameters = false;//禁止清除参数
                pars[1].Direction = ParameterDirection.Output; //将p2设为 output
                var spResult2 = db.SqlQuery("exec sp_school @p1,@p2 output", pars);
                db.IsClearParameters = true;//启动请动清除参数
                var outPutValue = pars[1].Value;//获取output @p2的值

                //获取第一行第一列的值
                string v1 = db.GetString("select '张三' 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高级拼接器写法

 using (var db = SugarDao.GetInstance())
            {
                //---------Sqlable,创建多表查询---------//

                //多表查询
                List 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")//可以多个WHERE
                   .OrderBy("id")
                   .SelectToList/*新的Model我这里没有所以写的School*/>("st.*", new { id = 1 });

                //多表分页
                List 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("st.*", "s.id", 1, 10);

                //多表分页WHERE加子查询
                List 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 )" /*这里面写子查询都可以*/)
                    .SelectToPageList("st.*", "s.id", 1, 10);



                //--------转成List Dynmaic 或者 Json-----//

                //不分页
                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 });

                //分页
                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("s").Join("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加子查询
                }
                var pars = new { id = id, name = name };
                int pageCount = sable.Count(pars);
                var list7 = sable.SelectToPageList("s.*", "l.id desc", 1, 20, pars);


            }

 

4、更新

                //指定列更新
                db.Update(new { name = "蓝翔14" }, it => it.id == 14); //只更新name列
                db.Updateint>(new { name = "蓝翔11 23 12", areaId = 2 }, 11, 23, 12);
                db.Updatestring>(new { name = "蓝翔2" }, new string[] { "11", "21" });
                db.Update(new { name = "蓝翔2" }, it => it.id == 100);



                //支持字典更新，适合动态权限
                var dic = new Dictionary<string, string>();
                dic.Add("name", "第十三条");
                dic.Add("areaId", "1");
                db.Updateint>(dic, 13);


                //整个实体更新
                db.Update(new School { id = 16, name = "蓝翔16", AreaId = 1 });
                db.Update(new School { id = 12, name = "蓝翔12", AreaId = 2 }, it => it.id == 18);
                db.Update(new School() { id = 11, name = "青鸟11" });

                //设置不更新列
                db.DisableUpdateColumns = new string[] { "CreateTime" };//设置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将不会被更新
                db.Update(updObj);
                //以前实现这种更新需要用指定列的方式实现，现在就简单多了。



                //批量更新   数据量小时建议使用
                var updateResult = db.UpdateRange(GetUpdateList());

                //批量更新  数据量大时建议使用
                var updateResult2 = db.SqlBulkReplace(GetUpdateList2());

 

5、删除和状态删除

               //删除
                db.Deleteint>(10);
                db.Delete(it => it.id > 100);
                //主键批量删除
                db.Deletestring>(new string[] { "100", "101", "102" });
                //非主键批量删除
                db.Deletestring>(it => it.name, new string[] { "" });
                db.Deleteint>(it => it.id, new int[] { 20, 22 });

                //假删除
                //db.FalseDelete("is_del", 100);
                //等同于 update school set is_del=1 where id in(100)
                //db.FalseDelete("is_del", it=>it.id==100);

 

6、插入

                db.Insert(GetInsertItem()); //插入一条记录 (有主键也好，没主键也好，有自增列也好都可以插进去)


                db.InsertRange(GetInsertList()); //批量插入 支持（别名表等功能）


                db.SqlBulkCopy(GetInsertList()); //批量插入 适合海量数据插入，要求实体与数据库一致，不支持(别名表、排除列等功能)



                //设置不插入列
                db.DisableInsertColumns = new string[] { "sex" };//sex列将不会插入值
                Student s = new Student()
                {
                    name = "张" + new Random().Next(1, int.MaxValue),
                    sex = "gril"
                };
                var id = db.Insert(s); //插入
                //查询刚插入的sex是否有值
                var sex = db.Queryable().Single(it => it.id == id.ObjToInt()).sex;//无值
                var name = db.Queryable().Single(it => it.id == id.ObjToInt()).name;//有值

 

7、枚举支持

  var stuList = db.Queryable().ToList();
                db.Insert(new Student() { sch_id = SchoolEnum.北大青鸟 });
                db.Update(new Student() { sch_id = SchoolEnum.it清华, id = 11 });
                var stuList2 = db.Queryable().Where(it => it.sch_id == SchoolEnum.全智).ToList();

 

8、实体生成加T4

 //可以结合别名表，请看别名表的用法
                //db.SetMappingTables(mappingTableList);

                db.ClassGenerating.CreateClassFiles(db, ("e:/TestModels"), "Models");

                //只生成student和school表的实体
                db.ClassGenerating.CreateClassFilesByTableNames(db, "e:/TestModels2", "Models", new string[] { "student", "school" });

                //根据表名生成class字符串
                var str = db.ClassGenerating.TableNameToClass(db, "Student");

                var dynamicToClassStr = db.ClassGenerating.DynamicToClass(new { id = 1 }, "dyName");

                //根据SQL语句生成class字符串
                var str2 = db.ClassGenerating.SqlToClass(db, "select top 1 * from Student", "student");

                //改变值（lassTemplate.ItemTemplate=XXXX）可以自定义格式
                var tempItem = ClassTemplate.ItemTemplate;//例如可以在生成的实体添加默认构造函数给指定的字段赋默认值或者公司信息等
                var temp = ClassTemplate.Template;



                //设置新格式模板
                //主键Guid.New(),
                //CreateTime为DateTime.Now 
                //IsRemove=0
                //UpdateTime为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";

                //新格式的实体字符串
                var str3 = db.ClassGenerating.TableNameToClass(db, "Student");

9、ADO.NET

  var r1 = db.GetDataTable("select * from student");
                var r2 = db.GetSingle("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");


                //参数支持
                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" } });//目前只支持 Dictionary和Dictionary
                var p3 = db.GetDataTable("select * from student where id=@id", new SqlParameter("@id",1) );

                {
                    //日志记录件事件里面用到数据库操作 IsEnableLogEvent一定要为false否则将引起死循环，并且要新开一个数据实例 像我这样写就没问题。
                    db.IsEnableLogEvent = false;
                    db.ExecuteCommand("select 1");
