EF中使用SQL语句或存储过程
1、无参数查询
var model = db.Database.SqlQuery<UserInfo>("select* from UserInfoes ").ToList();
2、有参查询
var model = db.Database.SqlQuery<UserInfo>("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);
