EF中使用语句 或存储过程 查询

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);

6、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);
