摘要：
一、前言该公司的团队项目和产品已经完全放弃了EF。SqlSugar的定位不是ORM，而是让您编写Sql。支持多种类型的返回值，如Json、Dynamic、List、List、ValueType和Dictionary也是一大亮点。
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
Sql查询2、Queryable 用于单表或者视图查询
单表查询3、Sqlable 用于多表查询
多表查询4、新容器转换
新容器转换添加
添加更新
更新删除和假删除
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
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
无参事务
事务公开函数
函数实体生成
实体生成T4模版
请查看Demos文件下的T4
别名表
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

}等Core成熟将第一时间兼容Core版本,本人小学毕业有错别字请见谅
