一、前言
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,而是为了方面的让你去写Sql。
支持Json 、Dynamic、 List<T>、 List<string[]>、 ValueType和 Dictionary 等多种类型的返回值也是一大亮点。
执行十万次【将拉姆达】转成【Sql】只用了1秒多（机型：Surface Pro4 I5 8G）
更多测试（机型：过时机器）
二、功能介绍
查询
1、SqlQuery 用于执行原生SQL和存储过程
//转成list List<Student> list1 = db.SqlQuery<Student>("select * from Student"); //转成list带参 List<Student> list2 = db.SqlQuery<Student>("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.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").Single(); //存储过程 var spResult = db.SqlQuery<School>("exec sp_school @p1,@p2", new { p1=1,p2=2 });Sql查询
2、Queryable 用于单表或者视图查询
//---------Queryable<T>,扩展函数查询---------// //针对单表或者视图查询 //查询所有 var student = db.Queryable<Student>().ToList(); var studentDynamic = db.Queryable<Student>().ToDynamic(); var studentJson = db.Queryable<Student>().ToJson(); //查询单条 var single = db.Queryable<Student>().Single(c => c.id == 1); //查询单条没有记录返回空对象 var single2 = db.Queryable<Student>().Where(c => c.id == 1).SingleOrDefault(); //查询第一条 var first = db.Queryable<Student>().Where(c => c.id == 1).First(); var first2 = db.Queryable<Student>().Where(c => c.id == 1).FirstOrDefault(); //取10-20条 var page1 = db.Queryable<Student>().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<Student>().Where(c => c.id > 10).OrderBy("id").ToPageList(2, 10); //查询条数 var count = db.Queryable<Student>().Where(c => c.id > 10).Count(); //从第2条开始以后取所有 var skip = db.Queryable<Student>().Where(c => c.id > 10).OrderBy("id").Skip(2).ToList(); //取前2条 var take = db.Queryable<Student>().Where(c => c.id > 10).OrderBy("id").Take(2).ToList(); // Not like string conval = "a"; var notLike = db.Queryable<Student>().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<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 => DateTime.Now > Convert.ToDateTime("2015-1-1")).ToList(); var convert4 = db.Queryable<Student>().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<Student>().Where(c => "a" == "a").Where("id>100").ToList(); var student13 = db.Queryable<Student>().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<Student>().Any(c => c.id == 100); bool isAny1 = db.Queryable<Student>().Any(c => c.id == 1); int maxId = db.Queryable<Student>().Max<Student, int>("id"); int minId = db.Queryable<Student>().Where(c => c.id > 0).Min<Student, int>("id"); //In var list1= db.Queryable<Student>().In("id", "1", "2", "3").ToList(); var list2=db.Queryable<Student>().In("id", new string[] { "1", "2", "3" }).ToList(); var list3=db.Queryable<Student>().In("id", new List<string> { "1", "2", "3" }).ToList(); var list4 = db.Queryable<Student>().Where(it=>it.id<10).In("id", new List<string> { "1", "2", "3" }).ToList(); //分组查询 var list5= db.Queryable<Student>().Where(c => c.id < 20).GroupBy("sex").Select<Student, SexTotal>("Sex,Count=count(*)").ToList(); //SELECT Sex,Count=count(*) FROM Student WHERE 1=1 AND (id < 20) GROUP BY Sex --生成结果单表查询
3、Sqlable 用于多表查询
//---------Sqlable,创建多表查询---------// //多表查询 List<School> dataList = db.Sqlable() .Form("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<School/*新的Model我这里没有所以写的School*/>("st.*", new { id = 1 }); //多表分页 List<School> dataPageList = db.Sqlable() .Form("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); //多表分页WHERE加子查询 List<School> dataPageList2 = db.Sqlable() .Form("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<School>("st.*", "s.id", 1, 10); //--------转成List Dynamic 或者 Json-----// //不分页 var list1 = db.Sqlable().Form("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=@id", JoinType.INNER).SelectToDynamic("*", new { id = 1 }); var list2 = db.Sqlable().Form("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=@id", JoinType.INNER).SelectToJson("*", new { id = 1 }); var list3 = db.Sqlable().Form("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().Form("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().Form("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().Form("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().Form<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加子查询 } var pars = new { id = id, name = name }; int pageCount = sable.Count(pars); var list7 = sable.SelectToPageList<Student>("s.*","l.id desc",1,20, pars);多表查询
4、新容器转换
using (SqlSugarClient db = SugarDao.GetInstance()) { var list2= db.Queryable<Student>().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<Student>().Where(c => c.id < 10).Select(c => new { newid = c.id, newname = c.name, xx_name = c.name }).ToDynamic();//匿名类转换 }新容器转换
添加
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**去) List<Student> list = new List<Student>() { 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 } }添加
更新
using (var db = SugarDao.GetInstance()) { //指定列更新 db.Update<School>(new { name = "蓝翔2" }, it => it.id == id); db.Update<School, int>(new { name = "蓝翔2" }, 1, 3, 12); db.Update<School, string>(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<School>(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。 }更新
删除和假删除
using (var db = SugarDao.GetInstance()) { //真删除 db.Delete<School, int>(10);//注意主键必需为实体类的第一个属性 db.Delete<School>(it => it.id > 100); db.Delete<School, string>(new string[] { "100", "101", "102" }); //假删除 //db.FalseDelete<school>("is_del", 100); //等同于 update school set is_del=0 where id in(100) //db.FalseDelete<school>("is_del", it=>it.id==100); }删除
全局过滤器
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
/// <summary> /// 过滤器 /// </summary> 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<Student>().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<Student>().Where("id=@id",new{id=1}) //sqlable var list2 = db.Sqlable().Form<Student>("s").SelectToList<Student>("*"); //同上 //sqlQuery var list3 = db.SqlQuery<Student>("select * from Student"); //同上 } } } /// <summary> /// 扩展SqlSugarClient /// </summary> public class SugarDaoFilter { //禁止实例化 private SugarDaoFilter() { } /// <summary> /// 页面所需要的过滤函数 /// </summary> private static Dictionary<string, Func<KeyValueObj>> _filterParas = new Dictionary<string, Func<KeyValueObj>>() { { "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; } }过滤器
无参模式
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<Student>().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<Student>().Where("id=@id", new { id=Request["id"] }).ToList(); }无参
事务
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; } }事务
公开函数
//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});函数
实体生成
//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） //db.ClassGenerating.CreateClassFiles(db,Server.MapPath("~/Models"),"Models"); //根据表名生成实体类文件 //db.ClassGenerating.CreateClassFilesByTableNames(db, Server.MapPath("~/Models"), "Models" , "student","school"); //根据表名生成class字符串 var str = db.ClassGenerating.TableNameToClass(db, "Student"); //根据SQL语句生成class字符串 var str2 = db.ClassGenerating.SqlToClass(db, "select top 1 * from Student", "student");实体生成
T4模版
请查看Demos文件下的T4
别名表
//-----单个-------// var list = db.Queryable<V_Student>("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<KeyValue> mappingTableList = new List<KeyValue>(){ new KeyValue(){ Key="FormAttr", Value="Flow_FormAttr"}, new KeyValue(){ Key="Student3", Value="Student"} }; db.SetMappingTables(mappingTableList);别名表
多库并行计算功能
using (CloudClient db = CloudDao.GetInstance()) { db.PageMaxHandleNumber = 1500; using (CommittableTransaction trans = new CommittableTransaction())//启用分布式事务 { db.Tran = trans; /*** 增、删、改 ***/ //根据配置的百分比，随机插入到某个节点库 var s = new student() { createTime = DateTime.Now, id = Guid.NewGuid(), name = Guid.NewGuid() + "" }; //db.Insert<student>(s, false/*false表示不是自增列*/); //数据库设计主键为GUID为佳多库计算不会冲突 ////并发请求所有节点找出这条数据更新 //s.name = "改11"; //db.Update<student>(s, it => it.id == s.id);//根据表达示更新 //db.Update<student, Guid>(s, s.id);//根据主键更新 //db.Update<student, Guid>(s, new Guid[] { s.id });//根据主键数组更新 ////并发请求所有节点找出这条数据删除 //db.Delete<student>(it => it.id == s.id); trans.Commit(); } db.TranDispose(); /*** 使用Taskable实现云计算 ***/ //多线程请求所有数据库节点，获取汇总结果 var taskDataTable = db.Taskable<DataTable>("SELECT max(NUM) FROM STUDENT").Tasks; foreach (var dr in taskDataTable)//遍历所有节点数据 { var dt = dr.Result.DataTable;//每个节点的数据 类型为DataTable var connectionName = dr.Result.ConnectionString; } //多线程请求所有数据库节点，获取汇总结果 var taskInt = db.Taskable<int>("SELECT max(NUM) FROM STUDENT").Tasks; foreach (var dr in taskInt)//遍历所有节点数据 { var dt = dr.Result.Value;//获取单个值 var connectionName = dr.Result.ConnectionString; } //多线程请求所有数据库节点，获取汇总结果 var taskEntity = db.Taskable<student>("SELECT top 100 * FROM STUDENT").Tasks; foreach (var dr in taskEntity)//遍历所有节点数据 { var dt = dr.Result.Entities;//获取实体集合 var connectionName = dr.Result.ConnectionString; } // //Taskable实现分组查询 // var groupList = db.Taskable<DataTable>("SELECT name,COUNT(*) AS [count],AVG(num) as num FROM STUDENT WHERE ID IS NOT NULL GROUP BY NAME ") // .Tasks // .SelectMany(it => it.Result.DataTable.AsEnumerable()) // .Select(dr => new { num = Convert.ToInt32(dr["NUM"]), name = dr["NAME"].ToString(), count = Convert.ToInt32(dr["COUNT"]) }) // .GroupBy(dr => dr.name).Select(dt => new { name = dt.First().name, count = dt.Sum(dtItem => dtItem.count), num = dt.Sum(dtItem => dtItem.num) / dt.Sum(dtItem => dtItem.count) }).ToList(); // //输出结果 // foreach (var it in groupList) // { // var num = it.num; // var name = it.name; // var count = it.count; // } // //简化 // var groupList2 = db.Taskable<DataTable>("SELECT NAME,COUNT(*) AS [COUNT],AVG(NUM) as NUM FROM STUDENT WHERE ID IS NOT NULL GROUP BY NAME ") //.MergeTable()//将结果集合并到一个集合 //.Select(dr => new { num = Convert.ToInt32(dr["NUM"]), name = dr["NAME"].ToString(), count = Convert.ToInt32(dr["COUNT"]) }) //.GroupBy(dr => dr.name).Select(dt => new { name = dt.First().name, count = dt.Sum(dtItem => dtItem.count), num = dt.Sum(dtItem => dtItem.num) / dt.Sum(dtItem => dtItem.count) }).ToList(); // //再简化 // List<V_Student> groupList3 = db.Taskable<V_Student>("SELECT name,COUNT(*) AS [count],AVG(num) as num FROM STUDENT WHERE ID IS NOT NULL GROUP BY NAME ") //.MergeEntities()//将结果集合并到一个集合 //.GroupBy(dr => dr.name).Select(dt => new V_Student { name = dt.First().name, count = dt.Sum(dtItem => dtItem.count), num = dt.Sum(dtItem => dtItem.num) / dt.Sum(dtItem => dtItem.count) }).ToList(); //更多简化函数 int maxValue = db.Taskable<int>("SELECT max(NUM) FROM STUDENT").Max();//求出所有节点的最大值 int minValue = db.Taskable<int>("SELECT min(NUM) FROM STUDENT").Min();//求出所有节点的最小值 var dataCount = db.Taskable<int>("SELECT count(1) FROM STUDENT").Count();//求出所有节点数据 // var avg = db.TaskableWithCount<int>("SELECT avg(num)", " FROM STUDENT").Avg(); var all = db.Taskable<student>("select * from student where Contains(name,@name)"/*使用contains需要建全文索引*/, new { name = "张三" }).ToList();//获取所有节点name为张三的数据,转为list var dnSingle = DateTime.Now; var data = db.Taskable<student>("select * from student where id=@id", new { id = id }).ToSingle();//从所有节点中查询一条记录 var timeSingle = (DateTime.Now - dnSingle).TotalSeconds; var dn = DateTime.Now; //单列排序 // var list = db.TaskableWithPage<student>("id", "select * from student "/*使用contains需要建全文索引*/, 2160, 25, ref pageCount, "num", OrderByType.desc, new { name = "\"*李*\"" }); var time = (DateTime.Now - dn).TotalSeconds; //多组排序 order by num,time var dn2 = DateTime.Now; var listMultipleOrderBy = db.TaskableWithPage<student>("id", "select * from student "/*使用contains需要建全文索引*/, 5000, 25, ref pageCount, new List<OrderByDictionary>() { new OrderByDictionary(){ OrderByField="num", OrderByType=OrderByType.asc}, // new OrderByDictionary(){ OrderByField="createTime", OrderByType=OrderByType.desc}, // new OrderByDictionary(){ OrderByField="createTime", OrderByType=OrderByType.asc} }, new { name = "\"*小*\"" }); var time2 = (DateTime.Now - dn2).TotalSeconds; }多库模式
