SqlSugar 高性能ORM 2.4 性能超Dapper 5% 和原生一样

因为我是作者所以是原创哈：

1、前言/Preface

SqlSugar从去年到现在已经一年了，版本从1.0升到了现在的2.3 ，这是一个稳定版本 ，有数家公司已经项目上线，在这里我将SqlSugar的功能重新整理成一篇新的贴子，希望大家喜欢。

 公司团队项目、产品已经完全抛弃EF，SqlSugar定位不是ORM,而是为了方便的让你去写Sql。

媲美原生ADO.NET的性能、简洁的语法和支持Json 、Dynamic、 List、 List、 ValueType和  Dictionary 等多种类型的返回值 有很多亮点。

 

SqlSugar from last year to now already a year, version from 1.0 up to now 2.3, which is a stable version, several companies have launched, here I will SqlSugar re consolidation into a new API, I hope everyone likes.

 

2、功能介绍/Product function introduction

查询/Search

 1、SqlQuery 用于执行原生SQL和存储过程   /   Execution of native SQL

           //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").Single();
                //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").Single();
                //存储过程
                var spResult = db.SqlQuery("exec sp_school @p1,@p2", new { p1=1,p2=2 });

 

2、Queryable 用于单表或者视图查询    / Select single table or view

  //---------Queryable,扩展函数查询---------//

                //针对单表或者视图查询

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

                //上一句的简化写法，同样取10-20条
                var page2 = db.Queryable().Where(c => c.id > 10).OrderBy("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("id").Skip(2).ToList();

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

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

                // 可以在拉姆达使用 ToString和 Convert,比EF出色的地方
                var convert1 = db.Queryable().Where(c => c.name == "a".ToString()).ToList();
                var convert2 = db.Queryable().Where(c => c.id == Convert.ToInt32("1")).ToList();// 
                var convert3 = db.Queryable().Where(c => DateTime.Now > Convert.ToDateTime("2015-1-1")).ToList();
                var convert4 = db.Queryable().Where(c => DateTime.Now > DateTime.Now).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>100").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);

                int maxId = db.Queryable().Maxint>("id");
                int minId = db.Queryable().Where(c => c.id > 0).Minint>("id");



                //In
                var list1= db.Queryable().In("id", "1", "2", "3").ToList();
                var list2=db.Queryable().In("id", new string[] { "1", "2", "3" }).ToList();
                var list3=db.Queryable().In("id", new List<string> { "1", "2", "3" }).ToList();
                var list4 = db.Queryable().Where(it=>it.id<10).In("id", new List<string> { "1", "2", "3" }).ToList();

                //分组查询
                var list5= 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

 

3、Sqlable 用于多表查询  / Complex query

//---------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
                   .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、新容器转换 / To new container

 using (SqlSugarClient db = SugarDao.GetInstance())
            {
                var list2= db.Queryable().Where(c => c.id < 10).Select(c => new classNew { newid = c.id, newname = c.name, xx_name = c.name }).ToList();//不支持匿名类转换,也不建议使用

                var list3 = db.Queryable().Where(c => c.id < 10).Select(c => new   { newid = c.id, newname = c.name, xx_name = c.name }).ToDynamic();//匿名类转换
            }

 

 

添加/Add

 using (SqlSugarClient db = SugarDao.GetInstance())//开启数据库连接
            {
                Student s = new Student()
                {
                    name = "张" + new Random().Next(1, int.MaxValue)
                };

                db.Insert(s); //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)


                List list = new List()
                {
                     new Student()
                {
                     name="张"+new Random().Next(1,int.MaxValue)
                },
                 new Student()
                {
                     name="张"+new Random().Next(1,int.MaxValue)
                }
                };

                db.InsertRange(list); //批量插入
            }
        }

 

更新/Update

 using (var db = SugarDao.GetInstance())
            {
                //指定列更新
                db.Update(new { name = "蓝翔2" }, it => it.id == id);
                db.Updateint>(new { name = "蓝翔2" }, 1, 3, 12);
                db.Updatestring>(new { name = "蓝翔2" }, new string[] { "1", "2" });

                //整个实体更新
                db.Update(new School { id = id, name = "蓝翔2" });
                db.Update(new School { id = id, name = "蓝翔2" }, it => it.id == id);


                //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。
               
            }

 

删除和假删除/Delete And False Delete

using (var db = SugarDao.GetInstance())
            {
                //真删除
                db.Deleteint>(10);//注意主键必需为实体类的第一个属性
                db.Delete(it => it.id > 100);
                db.Deletestring>(new string[] { "100", "101", "102" });

                //假删除
                //db.FalseDelete("is_del", 100);
                //等同于 update school set is_del=0 where id in(100)
                //db.FalseDelete("is_del", it=>it.id==100);
            }

 

全局过滤器/ Gobal Filter

这功能主要用于通用权限设计等功能， 当有很多WHERE重复，并且动态 这时候就需要在全局设置好过滤器接口集合，程序中使用只需要设KEY便可

    /// 

    /// 过滤器
    /// 
    public partial class Filter : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            using (SqlSugarClient db = SugarDaoFilter.GetInstance())//开启数据库连接
            {
                //设置走哪个过滤器
                db.CurrentFilterKey = "role";

                //queryable
                var list = db.Queryable().ToList(); //通过全局过滤器对需要权限验证的数据进行过滤
                //相当于db.Queryable().Where("id=@id",new{id=1})


                //sqlable
                var list2 = db.Sqlable().Form("s").SelectToList("*");
                //同上

                //sqlQuery
                var list3 = db.SqlQuery("select * from Student");
                //同上
            }
        }
    }
    /// 

    /// 扩展SqlSugarClient
    /// 
    public class SugarDaoFilter
    {
        //禁止实例化
        private SugarDaoFilter()
        {

        }
        /// 

        /// 页面所需要的过滤函数
        /// 
        private static Dictionary<string, Func> _filterParas = new Dictionary<string, Func>()
        {
          { "role",()=>{
                    return new KeyValueObj(){ Key=" id=@id" , Value=new{ id=1}};
               }
          },
          { "org",()=>{ 
                    return new KeyValueObj(){ Key=" orgId=@orgId" , Value=new{ orgId=1}};
              }
          },
        };
        public static SqlSugarClient GetInstance()
        {
            string connection = System.Configuration.ConfigurationManager.ConnectionStrings[@"sqlConn"].ToString(); //这里可以动态根据cookies或session实现多库切换
            var reval = new SqlSugarClient(connection);
            reval.SetFilterFilterParas(_filterParas);
            return reval;
        }
    }

 

无参模式/No Parameter

将IsGetPageParas设为true之后页面的参数都不需要使用  new{}来赋值

         using (SqlSugarClient db = SugarDao.GetInstance())//开启数据库连接
                {

                    db.IsGetPageParas = true;//使用无参模式直接将Requst中的ID传给@id无需在代码中写出来

                    var list = db.Queryable().Where("id=@id").ToList();

                    //sqlable queryable sqlquery通用

                    //获取页面所有参数到键值对
                    //var kvs= SqlSugarTool.GetParameterDictionary();

                    //以前写法
                    //var xx = db.Queryable().Where("id=@id", new { id=Request["id"] }).ToList();
                }

 

事务 /Transaction

 using (SqlSugarClient db = SugarDao.GetInstance())//开启数据库连接
            {
                db.IsNoLock = true;//启用无锁查询
                db.CommandTimeOut = 30000;//设置超时时间
                try
                {
                    db.BeginTran();//开启事务

                    db.CommitTran();//提交事务
                }
                catch (Exception)
                {
                    db.RollbackTran();//回滚事务
                    throw;
                }
            }

 

公开函数 /Common Method

 //ToJoinSqlInVal
            var par = new string[] { "a", "c", "3" };
            var ids = par.ToJoinSqlInVal();//将数组转成 'a','c','3'  有防SQL注入处理


            //ToSqlValue
            try
            {
                var par2 = "a'";
                var newpar2 = par2.ToSqlValue();//对字符串防注入处理
            }
            catch (Exception ex)
            {

                Response.Write(ex.Message);
            }

            //SqlLikeWordEncode 处理LIKE特殊字符
            var likestr = SqlSugarTool.SqlLikeWordEncode("[%%%");


            //GetParameterArray 获取页面参数所有参数的键和值
            var pars = SqlSugarTool.GetParameterArray();


            //将匿名对象转成SqlParameter
            var par3= SqlSugarTool.GetParameters(new { id=1});

 

实体生成 /Create Entity File

     //根据当前数据库生成所有表的实体类文件 （参数：SqlSugarClient ，文件目录，命名空间）

T4模版

请查看Demos文件下的T4

 

别名表/Rename table name

                //-----单个-------//
                var list = db.Queryable("Student").ToList();//查询的是 select * from student 而我的实体名称为V_Student




                //-----全局多个设置-------//

                //设置 Mapping Table 如果没这方面需求可以传NULL
                List mappingTableList = new List(){
                new KeyValue(){ Key="FormAttr", Value="Flow_FormAttr"},
                new KeyValue(){ Key="Student3", Value="Student"}
                };
                db.SetMappingTables(mappingTableList);
