2、功能介绍/Product function introduction

 

查询/Search

 

1、Queryable用于拉姆达操作数据库

 

2、SqlQuery用于执行SQL和存储过程

 

3、Sqlable一种更新近SQL的写法

 

1、Queryable 用于拉姆达表达式操作(支持Join多表)    / Select single table or view

  //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 singleOrDefault = db.Queryable<STUDENT>().SingleOrDefault(c => c.ID == 11111111);        //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(it => it.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(it => it.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(it => it.ID).Skip(2).ToList();        //取前2条        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>:id", new { id = 1 }).ToList();        var student13 = db.Queryable<STUDENT>().Where(c => "a" == "a").Where("id>100 ").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);        //获取最大Id        object maxId = db.Queryable<STUDENT>().Max(it => it.ID);        int maxId1 = db.Queryable<STUDENT>().Max(it => it.ID).ObjToInt();//拉姆达        int maxId2 = db.Queryable<STUDENT>().Max<STUDENT, int>("id"); //字符串写法        //获取最小        int minId1 = db.Queryable<STUDENT>().Where(c => c.ID > 0).Min(it => it.ID).ObjToInt();//拉姆达        int minId2 = db.Queryable<STUDENT>().Where(c => c.ID > 0).Min<STUDENT, int>("id");//字符串写法        //order By         var orderList = db.Queryable<STUDENT>().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<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 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();        //分组查询        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();        List<SexTotal> list9 = db.Queryable<STUDENT>().Where(c => c.ID < 20).GroupBy(it => it.SEX).Select<STUDENT, SexTotal>("SEX,count(*) COUNT").ToList();        List<SexTotal> list10 = 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        //2表关联查询        var jList = db.Queryable<STUDENT>()        .JoinTable<STUDENT, SCHOOL>((s1, s2) => s1.SCH_ID == s2.ID) //默认left join        .Where<STUDENT, SCHOOL>((s1, s2) => s1.ID == 1)        .Select("s1.*,s2.name as schName")        .ToDynamic();        /*等于同于         SELECT s1.*,s2.name as schName         FROM [Student] s1         LEFT JOIN [School] s2 ON s1.sch_id = s2.id         WHERE s1.id = 1 */        //2表关联查询并分页        var jList2 = db.Queryable<STUDENT>()        .JoinTable<STUDENT, SCHOOL>((s1, s2) => s1.SCH_ID == s2.ID) //默认left join          //如果要用inner join这么写          //.JoinTable<Student, School>((s1, s2) => s1.sch_id == s2.id ,JoinType.INNER)        .Where<STUDENT, SCHOOL>((s1, s2) => s1.ID > 1)        .OrderBy<STUDENT, SCHOOL>((s1, s2) => s1.NAME)        .Skip(10)        .Take(20)        .Select("s1.*,s2.name as schName")        .ToDynamic();        //3表查询并分页        var jList3 = db.Queryable<STUDENT>()        .JoinTable<STUDENT, SCHOOL>((s1, s2) => s1.SCH_ID == s2.ID) // left join School s2 on s1.id=s2.id        .JoinTable<STUDENT, SCHOOL>((s1, s3) => s1.SCH_ID == s3.ID) // left join School s3 on s1.id=s3.id        .Where<STUDENT, SCHOOL>((s1, s2) => s1.ID > 1) // where s1.id>1        .Where<STUDENT>(s1 => s1.ID > 0)        .OrderBy<STUDENT, SCHOOL>((s1, s2) => s1.ID) //order by s1.id 多个order可以 .oderBy().orderby 叠加         .Skip(10)        .Take(20)        .Select("s1.*,s2.name as schName,s3.name as schName2")//select目前只支持这种写法        .ToDynamic();        //上面的方式都是与第一张表join,第三张表想与第二张表join写法如下        List<classNew> jList4 = db.Queryable<STUDENT>()         .JoinTable<STUDENT, SCHOOL>((s1, s2) => s1.SCH_ID == s2.ID) // left join School s2 on s1.id=s2.id         .JoinTable<STUDENT, SCHOOL, AREA>((s1, s2, a1) => a1.ID == s2.AREAID)// left join Area a1 on a1.id=s2.AreaId         .Select<STUDENT, SCHOOL, AREA, classNew>((s1, s2, a1) => new classNew { NEWID = s1.ID, STUDENTNAME = s1.NAME, SCHOOLNAME = s2.NAME, AREANAME = a1.NAME }).ToList();        //最多支持5表查询,太过复杂的建议用Sqlable或者SqlQuery,我们的Queryable只适合轻量级的查询        //拼接        var queryable = db.Queryable<STUDENT>().Where(it => true);        if (maxId.ObjToInt() == 1)        {          queryable.Where(it => it.ID == 1);        }        else        {          queryable.Where(it => it.ID == 2);        }        var listJoin = queryable.ToList();        //queryable和SqlSugarClient解耦        var par = new Queryable<STUDENT>().Where(it => it.ID == 1);//声名没有connection对象的Queryable        par.DB = db;        var listPar = par.ToList();        //查看生成的sql和参数        var id=1;        var sqlAndPars = db.Queryable<STUDENT>().Where(it => it.ID == id).OrderBy(it => it.ID).ToSql();        //函数的支持(字段暂不支持函数,只有参数支持) 目前只支持这么多        var par1 = "2015-1-1"; var par2 = "  我 有空格, ";        var r1 = db.Queryable<STUDENT>().Where(it => it.NAME == par1.ObjToString()).ToSql(); //ObjToString会将null转转成""        var r2 = db.Queryable<INSERTTEST>().Where(it => it.D1 == par1.ObjToDate()).ToSql();        var r3 = db.Queryable<INSERTTEST>().Where(it => it.ID == 1.ObjToInt()).ToSql();//ObjToInt会将null转转成0        var r4 = db.Queryable<INSERTTEST>().Where(it => it.ID == 2.ObjToDecimal()).ToSql();        var r5 = db.Queryable<INSERTTEST>().Where(it => it.ID == 3.ObjToMoney()).ToSql();        var r6 = db.Queryable<INSERTTEST>().Where(it => it.V1 == par2.Trim()).ToSql();        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();        var c1 = db.Queryable<STUDENT>().Where(c =>c.NAME.Contains("a")).ToList();        var c2 = db.Queryable<STUDENT>().Where(c => c.NAME.StartsWith("a")).ToList();        var c3 = db.Queryable<STUDENT>().Where(c => c.NAME.EndsWith("a")).ToList();

 

 

 

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

using (var db = SugarDao.GetInstance())      {        //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  id from Student where rownum=1").SingleOrDefault();        //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  id,name from Student where rownum=1").SingleOrDefault();        //存储过程        //var spResult = db.SqlQuery<SCHOOL>(@"begin exec sp_school (:p1,:p2); end;", new { p1 = 1, p2 = 2 });        //获取第一行第一列的值        string v1 = db.GetString("select '张三' as name from dual");        int v2 = db.GetInt("select 1 as name from dual");        double v3 = db.GetDouble("select 1 as name from dual");        decimal v4 = db.GetDecimal("select 1 as name from dual");        //....      }

 

 

3、Sqlable 更贴近SQL的一种编程方式,适用于复杂查询 / Complex query

 //多表查询        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")//可以多个WHERE          .OrderBy("s.id")          .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()          .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);        //多表分页WHERE加子查询        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 as id from dual )" /*这里面写子查询都可以*/)          .SelectToPageList<SCHOOL>("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<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 id from school where rownum<10)");//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);

4、新容器转换 / To new container

 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        var list4 = db.Queryable<STUDENT>().Where(c => c.ID < 10).Select("id as newid, name as newname ,name as xx_name").ToDynamic();//匿名类转换        var jList1 = db.Queryable<STUDENT>()         .JoinTable<STUDENT, SCHOOL>((s1, s2) => s1.SCH_ID == s2.ID) // left join School s2 on s1.id=s2.id         .Where<STUDENT, SCHOOL>((s1, s2) => s1.ID > 1) // where s1.id>1         .OrderBy<STUDENT, SCHOOL>((s1, s2) => s1.ID) //order by s1.id 多个order可以 .oderBy().orderby 叠加          .Skip(1)         .Take(2)         .Select<STUDENT, SCHOOL, classNew>((s1, s2) => new classNew() { NEWID = s1.ID, NEWNAME = s2.NAME, XX_NAME = s1.NAME })//select目前只支持这种写法         .ToList();        var jList2 = db.Queryable<STUDENT>()        .JoinTable<STUDENT, SCHOOL>((s1, s2) => s1.SCH_ID == s2.ID) // left join School s2 on s1.id=s2.id        .Where<STUDENT, SCHOOL>((s1, s2) => s1.ID > 1) // where s1.id>1        .OrderBy<STUDENT, SCHOOL>((s1, s2) => s1.ID) //order by s1.id 多个order可以 .oderBy().orderby 叠加         .Skip(1)        .Take(2)        .Select<STUDENT, SCHOOL, classNew>((s1, s2) => new classNew() { NEWID = s1.ID, NEWNAME = s1.NAME, XX_NAME = s1.NAME })//select目前只支持这种写法        .ToDynamic();        var jList3 = db.Queryable<STUDENT>()        .JoinTable<STUDENT, SCHOOL>((s1, s2) => s1.SCH_ID == s2.ID) // left join School s2 on s1.id=s2.id        .Where<STUDENT, SCHOOL>((s1, s2) => s1.ID > 1) // where s1.id>1        .OrderBy<STUDENT, SCHOOL>((s1, s2) => s1.ID) //order by s1.id 多个order可以 .oderBy().orderby 叠加         .Skip(1)        .Take(2)        .Select<STUDENT, classNew>(s1 => new classNew() { NEWID = s1.ID, NEWNAME = s1.NAME, XX_NAME = s1.NAME })//select目前只支持这种写法        .ToDynamic();      }

 

 

 

添加/Add

      //设置序列,程序起动时设置一次便可      OracleConfig.SequenceMapping = new List<PubModel.SequenceModel>()      {         new PubModel.SequenceModel(){ ColumnName="ID", TableName="STUDENT", Value="SEQ_D"}       };      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<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      }

 

 

更新/Update

      int id = 11;      //设置序列      OracleConfig.SequenceMapping = new List<PubModel.SequenceModel>()      {         new PubModel.SequenceModel(){ ColumnName="IDENTITYFIELD", TableName="TESTUPDATECOLUMNS", Value="SEQ_D"}       };      using (var db = SugarDao.GetInstance())      {        //指定列更新        db.Update<SCHOOL>(new { name = "蓝翔14" }, it => it.ID == 14);        db.Update<SCHOOL, int>(new { name = "蓝翔11 23 12", areaId=2 }, 11, 23, 12);        db.Update<SCHOOL, string>(new { name = "蓝翔2" }, new string[] { "11", "21" });        db.Update<SCHOOL>(new { name = "蓝翔2" }, it => it.ID == id);          //支持字段指定列更新,适合动态权限        var dic =new Dictionary<string, string>();        dic.Add("name","第十三条");        dic.Add("areaId", "1");        db.Update<SCHOOL,int>(dic, 13);        db.Update<SCHOOL>(dic, it => it.ID == 13);        //整个实体更新        db.Update(new SCHOOL { ID = 16, NAME = "蓝翔16", AREAID=1 });        db.Update<SCHOOL>(new SCHOOL { ID = id, NAME = "蓝翔18", AREAID=2 }, it => it.ID == 18);        db.Update<SCHOOL>(new SCHOOL() { ID = 11, NAME = "xx" });        //设置不更新列        db.DisableUpdateColumns = new string[] { "CreateTime" };//设置CreateTime不更新        TESTUPDATECOLUMNS updObj = new TESTUPDATECOLUMNS()        {          VGUID = "542b5a27-6984-47c7-a8ee-359e483c8470",          NAME = "xx",          NAME2 = "xx2",          IDENTITYFIELD = 1,          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.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/ 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

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using OracleSugar;using Models;namespace WebTest.Demo{  /// <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().From<STUDENT>("s").SelectToList<STUDENT>("*");        //同上        //sqlQuery        var list3 = db.SqlQuery<STUDENT>("select * from Student WHERE 1=1");        //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;    }  }}
