[.NET开发] EF中使用SQL语句或存储过程

发表于 2018-4-24 08:00:01
EF中使用SQL语句或存储过程 1、无参数查询 var model = db.Database.SqlQuery("select* from UserInfoes ").ToList(); 2、有参查询 var model = db.Database.SqlQuery("select* from UserInfoes where id=@ID ",new SqlParameter("@ID",id)).ToList(); 3、结合linq查询 var model = (from p in db.userinfo.SqlQuery("select * from UserInfoes where id=@ID", new SqlParameter("@ID", 1)) select p).ToList(); 4:EF原始查询单独表 model = db.userinfo.OrderByDescending(a => a.ID).Skip(10 * (当前页 - 1)).Take(10).ToList(); 5,EF 执行存储过程或delete 删除语句 SqlParameter[] para = new SqlParameter[] { new SqlParameter("@ID",id) }; db.Database.ExecuteSqlCommand("delete UserInfoes where id=@ID", para); 存储过程 删除,有几个参数,存储后面要带几个参数以逗号分隔 SqlParameter[] para = new SqlParameter[] { new SqlParameter("@ID",id) }; db.Database.ExecuteSqlCommand("sp_Userinfos_deleteByID @ID", para); 转载来源:https://www.cnblogs.com/lvdongjie/p/5856306.html
