我有一个zfs服务器,为了理解,我运行了几个愚蠢的测试,这让我很困惑。
上下文:- FreeBSD 11.2,启用压缩的ZFS,SAS,RAIDz2,768 of内存。
这两个命令都直接在FreeBSD服务器上运行。
# time dd if=/dev/random of=./test_file bs=128k count=131072

我有这个代码(注意l.FirstOrDefault().Name):)
var qry = from peron in db.Persons
join room in db.Rooms on peron.Room.Id equals room.Id
join passport in db.Passports on peron.Passport.Id equals passport.Id
select new {peron.Fio, room.Name, passport.Number, Count = 0};
qry = qry.GroupBy(l =&
我可以得到最近的日期,但我无法得到最小值。我在这里试图得到的是,我想显示每个病人的每个findingAbbr的最小值,以及他们最近的创建日期和这个最小值的时间。有人能告诉我我在这个问题上做错了什么吗?
谢谢你的帮助!

我有一个邻接模型列表,查询如下:
SELECT t1.FIO AS lev1, t2.FIO AS lev2, t3.FIO AS lev3, t4.FIO AS lev4, t5.FIO AS lev5, t6.FIO AS lev6, t7.FIO AS lev7, t8.FIO AS lev8, t9.FIO AS lev9, t10.FIO AS lev10, t11.FIO AS lev11, t12.FIO AS lev12, t13.FIO AS lev13, t14.FIO AS lev14, t15.FIO AS lev15, t16.FIO AS lev16, t17.FI
请帮帮我。当发送姓氏、名字和父源数据时,表单不起作用,不断要求输入3个单词 validFio: function () {
var fio = this.getData()["fio"];
if (!fio) {
return "Не введен Ф.И.О.";
}
if (fio.split("/s+/g").length !== 3) {
return "Ф.И.О. должно состоять из трех слов!";
}
return "OK"; },
