EF中使用SQL语句或存储过程

EF中使用SQL语句或存储过程

1、无参数查询

varmodel = db.Database.SqlQuery<UserInfo>("select* from UserInfoes ").ToList();

2、有参查询

varmodel = db.Database.SqlQuery<UserInfo>("select* from UserInfoes where id=@ID ",newSqlParameter("@ID",id)).ToList();

3、结合linq查询

varmodel = (fromindb.userinfo.SqlQuery("select * from UserInfoes where id=@ID"newSqlParameter("@ID"selectp).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

newSqlParameter[] {

newSqlParameter("@ID",id)

};

db.Database.ExecuteSqlCommand(, 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

newSqlParameter[] {

newSqlParameter("@ID",id)

};

db.Database.ExecuteSqlCommand("sp_Userinfos_deleteByID @ID", para);
