5、带有实体生成函数和T4模版生成实体
6、无需任何配置 ，还你一个干净的model
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 == );
//查询单条没有记录返回空对象
var singleOrDefault = db.Queryable<STUDENT>().SingleOrDefault(c => c.ID == );
//查询单条没有记录返回空对象
var single2 = db.Queryable<STUDENT>().Where(c => c.ID == ).SingleOrDefault(); //查询第一条
var first = db.Queryable<STUDENT>().Where(c => c.ID == ).First();
var first2 = db.Queryable<STUDENT>().Where(c => c.ID == ).FirstOrDefault(); //取10-20条
var page1 = db.Queryable<STUDENT>().Where(c => c.ID > ).OrderBy(it => it.ID).Skip().Take().ToList(); //上一句的简化写法，同样取10-20条
var page2 = db.Queryable<STUDENT>().Where(c => c.ID > ).OrderBy(it => it.ID).ToPageList(, ); //查询条数
var count = db.Queryable<STUDENT>().Where(c => c.ID > ).Count(); //从第2条开始以后取所有
var skip = db.Queryable<STUDENT>().Where(c => c.ID > ).OrderBy(it => it.ID).Skip().ToList(); //取前2条
var take = db.Queryable<STUDENT>().Where(c => c.ID > ).OrderBy(it => it.ID).Take().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 = }).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 == );
bool isAny1 = db.Queryable<STUDENT>().Any(c => c.ID == ); //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 > ).Min(it => it.ID).ObjToInt();//拉姆达
int minId2 = db.Queryable<STUDENT>().Where(c => c.ID > ).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[] { "", "", "" };
var intList = intArray.ToList();
var list0 = db.Queryable<STUDENT>().In(it => it.ID, , , ).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 < ).GroupBy(it => it.SEX).Select("sex,count(*) count").ToDynamic();
var list8 = db.Queryable<STUDENT>().Where(c => c.ID < ).GroupBy(it => it.SEX).GroupBy(it => it.ID).Select("id,sex,count(*) count").ToDynamic();
List<SexTotal> list9 = db.Queryable<STUDENT>().Where(c => c.ID < ).GroupBy(it => it.SEX).Select<STUDENT, SexTotal>("SEX,count(*) COUNT").ToList();
List<SexTotal> list10 = db.Queryable<STUDENT>().Where(c => c.ID < ).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 == )
.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 > )
.OrderBy<STUDENT, SCHOOL>((s1, s2) => s1.NAME)
.Skip()
.Take()
.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 > ) // where s1.id>1
.Where<STUDENT>(s1 => s1.ID > )
.OrderBy<STUDENT, SCHOOL>((s1, s2) => s1.ID) //order by s1.id 多个order可以 .oderBy().orderby 叠加
.Skip()
.Take()
.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() == )
{
queryable.Where(it => it.ID == );
}
else
{
queryable.Where(it => it.ID == );
}
var listJoin = queryable.ToList(); //queryable和SqlSugarClient解耦
var par = new Queryable<STUDENT>().Where(it => it.ID == );//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=;
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 == .ObjToInt()).ToSql();//ObjToInt会将null转转成0
var r4 = db.Queryable<INSERTTEST>().Where(it => it.ID == .ObjToDecimal()).ToSql();
var r5 = db.Queryable<INSERTTEST>().Where(it => it.ID == .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("")).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 = });
//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 = }); //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", , ); //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", , ); //--------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 = });
var list2 = db.Sqlable().From("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=:id", JoinType.INNER).SelectToJson("*", new { id = });
var list3 = db.Sqlable().From("student", "s").Join("school", "l", "s.sch_id", "l.id and l.id=:id", JoinType.INNER).SelectToDataTable("*", new { id = }); //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", , , new { id = });
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", , , new { id = });
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", , , new { id = }); //--------拼接-----//
Sqlable sable = db.Sqlable().From<STUDENT>("s").Join<SCHOOL>("l", "s.sch_id", "l.id", JoinType.INNER);
string name = "a";
int id = ;
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 > )
{
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", , , pars);
4、新容器转换 / To new container
using (SqlSugarClient db = SugarDao.GetInstance())
{
var list2 = db.Queryable<STUDENT>().Where(c => c.ID < ).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 < ).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 < ).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 > ) // 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()
.Take()
.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 > ) // 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()
.Take()
.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 > ) // 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()
.Take()
.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(, 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(,int.MaxValue)
},
new STUDENT()
{
NAME="张"+new Random().Next(,int.MaxValue)
}
}; db.InsertRange(list); //批量插入
}
更新/Update
int id = ;
using (var db = SugarDao.GetInstance())
{
//指定列更新
db.Update<SCHOOL>(new { name = "蓝翔14" }, it => it.ID == );
db.Update<SCHOOL, int>(new { name = "蓝翔11 23 12", areaId= }, , , );
db.Update<SCHOOL, string>(new { name = "蓝翔2" }, new string[] { "", "" });
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", "");
db.Update<SCHOOL,int>(dic, );
db.Update<SCHOOL>(dic, it => it.ID == ); //整个实体更新
db.Update(new SCHOOL { ID = , NAME = "蓝翔16", AREAID= });
db.Update<SCHOOL>(new SCHOOL { ID = id, NAME = "蓝翔18", AREAID= }, it => it.ID == );
db.Update<SCHOOL>(new SCHOOL() { ID = , 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 = ,
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>();//注意主键必需为实体类的第一个属性
db.Delete<School>(it => it.id > );
db.Delete<School, string>(new string[] { "", "", "" }); //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
