oracle的某个字段怎么不能判断=' and is not null?。

null和‘"是不一样的,在数据是未知数或者无法使用时,大多数的数据库管理系统将存储一个叫做Null值的特殊值。不要将它和零(一个合法数值)、零长度串(不含有字符的一种串数据类型)或空格字符混淆起来。SQL-3标准中把一个Null定义为:“...一个用来指明任何数据值都不存在的一个特殊值...”Oracle中有一个空值调用函数:ISNULL功能:使用指定的替换值替换NULL。语法ISNULL(check_expression,replacement_value)参数check_expression将被检查是否为NULL的表达式。check_expression可以是任何类型的。replacement_value在check_expression为NULL时将返回的表达式。replacement_value必须与check_expresssion具有相同的类型。返回类型返回与check_expression相同的类型。注释如果check_expression不为NULL,那么返回该表达式的值;否则返回replacement_value。一个例子:使用ISNULL下面的示例为titles表中的所有书选择书名、类型及价格。如果一个书名的价格是NULL,那么在结果集中显示的价格为0.00。SELECTSUBSTRING(title,1,15)ASTitle,typeASType,ISNULL(price,0.00)ASPriceFROMtitles

oracle字段加了default默认值,还需要not null约束吗?

默认值仅仅是你在初次进行insert的时候,如果不提供值,则使用默认值。x0dx0a如果后续你进行update,将这个值改为null,则也是可以的,此时,并不会使用默认值。x0dx0a由此可见default并不会取代not null约束。x0dx0a如果是insert的话,default可以覆盖not null约束x0dx0a如果update,则default不一定能覆盖not null约束

oracle字段加了default默认值,还需要not null约束吗?

给oracle的date字段加not null

直接编辑表结构,把为空的复选框选中去掉就可以了

oracle 和 is not NULL的区别?

<>""只能判断空字符串,is Null是对Null字符的判断,两种完全不同的数据。一个是空字符,是个字符串,只不过是没有值,另一个是空值(Null)。Null在数据库中是特有的一类数据。="" 和<>""is null和is not null

oracle字段加了default默认值,还需要not null约束吗,可不可以省略

需要加,如果你给了default约束,此列还是可以存储空值,比如:create table t(A NUMBER,B VARCHAR2(10) DEFAULT "ABC");INSERT INTO T VALUES(1,NULL);B列存储了一个空值.

oracle字段加了default默认值,还需要not null约束吗,可不可以省略

你好!需要加,如果你给了default约束,此列还是可以存储空值,比如:createtablet(ANUMBER,BVARCHAR2(10)DEFAULT"ABC");INSERTINTOTVALUES(1,NULL);B列存储了一个空值.如有疑问,请追问。

Oracle一般有哪些版本?各个版本有什么区别?

1977年,Larry Ellison、Bob Miner和Ed Oates等人组建了Relational软件公司(Relational Software Inc.,RSI)。他们决定使用C语言和SQL界面构建一个关系数据库管理系统(Relational Database Management System,RDBMS),并很快发布了第一个版本(仅是原型系统)。x0dx0ax0dx0a1979年,RSI首次向客户发布了产品,即第2版。该版本的RDBMS可以在装有RSX-11操作系统的PDP-11机器上运行,后来又移植到了DEC VAX系统。x0dx0ax0dx0a1983年,发布的第3个版本中加入了SQL语言,而且性能也有所提升,其他功能也得到增强。与前几个版本不同的是,这个版本是完全用C语言编写的。同年,RSI更名为Oracle Corporation,也就是今天的Oracle公司。x0dx0ax0dx0a1984年,Oracle的第4版发布。该版本既支持VAX系统,也支持IBM VM操作系统。这也是第一个加入了读一致性(Read-consistency)的版本。x0dx0ax0dx0a1985年,Oracle的第5版发布。该版本可称作是Oracle发展史上的里程碑,因为它通过SQL*Net引入了客户端/服务器的计算机模式,同时它也是第一个打破640KB内存限制的MS-DOS产品。x0dx0ax0dx0a1988年,Oracle的第6版发布。该版本除了改进性能、增强序列生成与延迟写入(Deferred Writes)功能以外,还引入了底层锁。除此之外,该版本还加入了PL/SQL和热备份等功能。这时Oracle已经可以在许多平台和操作系统上运行。x0dx0ax0dx0a1991年,Oracle RDBMS的6.1版在DEC VAX平台中引入了Parallel Server选项,很快该选项也可用于许多其他平台。x0dx0ax0dx0a1992年,Oracle 7发布。Oracle 7在对内存、CPU和I/O的利用方面作了许多体系结构上的变动,这是一个功能完整的关系数据库管理系统,在易用性方面也作了许多改进,引入了SQL*DBA工具和database角色。x0dx0ax0dx0a1997年,Oracle 8发布。Oracle 8除了增加许多新特性和管理工具以外,还加入了对象扩展(Object Extension)特性。x0dx0ax0dx0a2001年,Oracle 9i release 1发布。这是Oracle 9i的第一个发行版,包含RAC(Real Application Cluster)等新功能。x0dx0ax0dx0a2002年,Oracle 9i release 2发布,它在release 1的基础上增加了集群文件系统(Cluster File System)等特性。x0dx0ax0dx0a2004年,针对网格计算的Oracle 10g发布。该版本中Oracle的功能、稳定性和性能的实现都达到了一个新的水平。x0dx0ax0dx0a2007年年7月12日,甲骨文公司推出的最新数据库软件Oracle 11g,Oracle 11g有400多项功能,经过了1500万个小时的测试,开发工作量达到了3.6万人/月。相对过往版本而言,Oracle 11g具有了与众不同的特性。

关于nuclear的雅思写作范文

  提高写作,必看范文,下面我就为考生们带来一篇 有关nuclear的雅思写作范文 ,考生们可以参考一下写作思路,改善自身写作方式。希望对你的写作有所帮助。   Advantages and Disadvantages of Nuclear Energy   Advantages of Nuclear Energy   Nuclear reactions release a million times more energy, as compared to hydro or wind energy. Hence, a large amount of electricity can be generated. Presently, approximately 10-15% of the world"s electricity is generated through nuclear energy. Did you know that one kilogram of uranium-235 approximately produces as much energy as 1,500 tons of coal?   The biggest advantage of this energy is that greenhouse gases are not released during a nuclear reaction. Greenhouse gases are a major threat in the current scenario, as they cause global warming and climate change. As there is no emission of these gases during nuclear reaction, there is very little effect on the environment.   The burning of fossil fuels leads to production of carbon dioxide and smoke. It is a menace to the environment as well as human life. Production of nuclear energy does not emit smoke, hence, there is no direct air pollution. However, disposal of radioactive waste is a major issue today.   Nuclear reactors make use of uranium as fuel. Fission reaction of a small amount of uranium generates a large amount of energy. Currently, the reserves of uranium found on the Earth are expected to last for another 100 years. Secondly, using this energy can make many nations energy independent, and not dependent on those unearthing fossil fuels.   Without human errors, accidents, or natural calamities, the nuclear reactors work very well and can go on for a long time. Secondly, once constructed, the plant requires very few people to operate it.   Disadvantages of Nuclear Energy   Accidental release of harmful radiation is one of the biggest drawbacks of nuclear energy. The fission process releases radiation, but, is controlled in a nuclear reactor. Now, if these safety measures fail, the radiation may come in contact with the environment, resulting in severe damage to the ecosystem and loss of life.   Although they produce large amount of energy, nuclear reactors depend on uranium, which is an exhaustible fuel. Its extinction can again cause a grave problem. Once exhausted, the reactors will be of no use, will have to be shutdown, but will remain occupying large area of land, and contaminating the environment.   This energy can be used for production and proliferation of nuclear weapons. Nuclear weapons make use of fission, fusion, or combination of both reactions for destructive purposes. They are a major threat to the world as they can cause a large-scale devastation. Their effects can be observed for many generations   Though large amount of energy can be produced from a nuclear power plant, it requires large capital cost. Around 10-15 years are required to develop a single plant. It is not very feasible to build a nuclear power plant. Secondly, one cannot ignore the fact that the nuclear reactors will work as long as uranium is available.   The waste produced after fission reactions contains unstable elements, and is highly radioactive. It is very dangerous to the environment as well as human health, and remains so for hundreds of years. It needs professional handling and should be kept isolated from the living environment. The radioactivity of these elements reduces over a period, after decaying. Hence, they have to be carefully stored and disposed. It is very difficult to store radioactive elements for a long period.   There have been two most disastrous nuclear power plant accidents to date: the Chernobyl disaster that occurred at the Chernobyl Nuclear Power Plant in Ukraine, and the Fukushima Daiichi nuclear disaster in Japan. Large amount of radiation was released in the environment after these incidents, leading to fatalities, damage of nature, and land. One cannot deny the possibility of repetition of such disasters in future.   As mentioned at the beginning of this article, there is an ongoing debate about the use of nuclear energy. There are proponents and opponents of it. Knowing the pros and cons in detail will help know more about the debate and the issues involved. However, only the future will make it clear whether nuclear energy is a boon or a bane!   以上就是雅思为您带来的有关nuclear的雅思写作范文,考生们可以拿做参考,但实战中最好不要完全照搬,雅思写作范文只是为考生们做个示范,实战中写作还是要发挥自身的特色。

nuclear为什么叫核皇

Nuclear之所以会在国内成功被封为“核皇”,主要还是洲际赛上他那七分半分钟就死了3次的卡莎实在是太让人印象深刻了。不过得益于世界赛版本变动,核皇在小组赛里倒是表现地中规中矩,在下路可以选小法亚索这些工具人的情况下,大部分队伍都不想浪费ban位去限制Nuclear,所以他可以比较轻松地拿到卡莎或者霞这样的版本OP英雄。备注:很多人觉得核皇只会玩卡莎,但是查阅了很多资料以后发现,其实他的寒冰胜率非常高。《英雄联盟》(League of Legends,简称LOL)是由美国拳头游戏(Riot Games)开发、中国内地由腾讯游戏代理运营的英雄对战MOBA竞技网游。游戏里拥有数百个个性英雄,并拥有排位系统、符文系统等特色养成系统。《英雄联盟》致力于推动全球电子竞技的发展,除了联动各赛区发展职业联赛、打造电竞体系之外,每年还会举办"英雄联盟季中冠军赛""英雄联盟全球总决赛""英雄联盟全明星赛"三大世界级赛事,形成了自己独有的电子竞技文化 。
