stime

问题一：extract是取到的systimestamp的小时数，是按照时区0来取的，所以和当前小时值不符。select extract(hour from cast(systimestamp as timestamp)) hz from dual;这个语句就可以取到正确的小时。问题二：虽然sysdate带时分秒。但是extract无法从DATE型中取到时分秒。If HOUR, MINUTE, or SECOND is requested, then expr must evaluate to an expression of datatype TIMESTAMP, TIMESTAMP WITH TIME ZONE, TIMESTAMP WITH LOCAL TIME ZONE, or INTERVAL DAY TO SECOND. DATE is not valid here, because Oracle Database treats it as ANSI DATE datatype, which has no time fields.

你好！我帮你写了两篇作文，因为不清楚你对作文的水平要求，所以在我平时写论文的基础上简化了一些。因为我在美国生活，所以作文是比较标准的美语。平时在大学经常写三千词论文，而且成绩一直很好，所以请你放心使用哈！！ 娱乐的这个我写的舞蹈，不好意思忘记考虑性别问题了，但是男生可以跳街舞的是吧……嘻嘻^_^ My Favorite Pastime Academic study is very important, but pastime is almost, if not as important as studying for a student. My favorite pastime is dancing, and there are several main reasons of why I like dancing the best as a pastime. First of all, when I dance, I could put aside the stress from school, and simply enjoy the dance music and the moves. Second, dancing helps me keep fit and healthy. Nowadays, it is common for students to have neck or back pains from sitting for too long, but sports and dancing can effectively solve the problem by giving us a break from books and computers. Last, I can meet many new friends from my dance classes and from other dance groups, which definitely adds color to my student life.备注：128词 Is Writing Better than Calling As the development of technology, the use of mobile phones has become a very important part of people"s daily lives. As a result, calling has started taking place of writing gradually. However, which way is better for communications? I believe that writing is better than calling. First, writing is a more formal way for communications, while calling tends to be more casual. Therefore, in the case of formal events, such as business communications, calling prevails over calling. Second, writing allows people to phrase more carefully, whereas calling seems a little rash comparatively. Third, it is easier for writing to keep records of communications. Therefore, I cast my vote for writing.备注：115词如果有不明白的地方请尽管提问！^_^

hobby是一生追求的爱好比如集邮，画画pastime只是打发时间的事情比如打牌，打游戏但是如果你把打游戏作为你毕生的爱好，也是可以的，用hobby所以上面两句有区别，区别就在于这件事在你心中的地位。

Peter can"t play tomorrow, he"s ( gone ) down with flu. 彼得明天不能参赛了, 他得了流感2.词语有问题，抄清楚点3.We should be able to dig up enough money for your ticket. 我们应该能够筹集到足够的钱供你买票.4.A fat man has much more flesh than a thin man. 胖人较瘦人肉多.5.

It"s 6 o" clock. It"s time for dinner.意思是六点钟了，该吃晚饭了。

It"s time to have dinner .

该吃蛋糕的时间了

应该是Romantic time吧。浪漫时光。希望可以帮到你。祝学习进步。

It"s time to meet. 是见面的时候了。 该见面了。

可以填for。即，Hurry,up.It is time for dinner.句意: 快点，到了该吃晚饭的时间了。注意:1.for是介词，后可以接名词。2.固定句型it istime for sth“到了该做某事的时间了”。

c 库 time函数，如果时间获取失败，则返回-1。If the function could not retrieve the calendar time, it returns a value of -1.if (stime != (time_t)(INVALID_VALUE))这句话是判断是否获取时间失败。

不需要。PLAYSTATIONVR（PSVR）是索尼电脑娱乐公司（SCE）推出的VR头显（虚拟现实头戴式显示器）。是基于PlayStation游戏机系列的第四代游戏主机（PS4）的虚拟现实装置。2016年10月13日全球同步发售。2016年3月17日，索尼正式公布了PSVR的售价为399美元。该价格即便是在购买齐全所需要的PS4主机和PSVR摄像头，总共也只需要810美元，该价格相对于单独设备就需要600美元的OculusRift和800美元的HTCVIVE来说很有优势，因为后两者还需要配置一台价格不菲的高性能电脑。面对如此低廉的价格，外界也有猜测索尼是否是在赔本赚吆喝，为了市场而采取的过激手段。

你说的是steam吧，有些游戏需要花钱买

有的111看我简介~

STEAM本身有离线模式的。但使用离线模式前，你必须用本机成功登陆过你的账号才行。其次在离线模式下，STEAM游戏能不能玩，是要看游戏本身的。如果你的游戏是纯多人游戏，那离线肯定不能玩。如果你的游戏是有单人游戏，基本上可以玩。但部分游戏会要求强制联网，这是游戏开发商决定的，跟STEAM无关。

第一，拼七巧板，好了之后会有抽屉打开，里面有本作业题，找到相同的两句话，是咚咚咚，敲击门旁边的盒子，会开门，里面有指纹密码锁，床底下有一个假的手指头，打开锁喉，柜子里面有男人的尸体，兜里有提示，第一个房间门里有数独题，完成后电脑会开机，根据提示输入电脑密码，看邮箱，会有抽屉打开，里面有女儿死亡时间，最后一个房间会打开，后面根据提示吧，也快结束了，一个小时左右

开启了离线模式。steam离线模式就是用户无需联网即可登录steam运行游戏，steam上有些单机游戏无需联网即可游玩，但是用户网络有时候不给力，所以这个离线模式就可以让你快速进入steam运行游戏。点击左上角steam按钮打开菜单，然后你就会看到进入离线模式，点击后重启steam，然后就可以进入steam的离线模式。

游戏说明里面没有解决的方法吗，应该有吧。现在大家都去玩这个了，去网易官网下载,非官网的经常出问题的邀请码：gsak7435序列号激活方式：①打开客户端进入游戏，输入账号密码，选择服务器； ②完成新手教程后，点击界面右下方“+号”-“设置”-“礼包兑换”后填写序列号。
