如何在linux下重启oracle数据库

如果确定ORACLE的服务端已经安装完毕(客户端一般是不需要安装的)---- 重启数据库服务(1) 以oracle身份登录数据库,命令:su – oracle (2) 进入Sqlplus控制台,命令:sqlplus /nolog (3) 以系统管理员登录,命令:connect / as sysdba (4) 启动数据库,命令:startup (5) 如果是关闭数据库,命令:shutdown immediate /SHUTDOWN ABORT(6) 退出sqlplus控制台,命令:exit (7) 进入监听器控制台,命令:lsnrctl (8) 启动监听器,命令:start (9) 退出监听器控制台,命令:exit (10) 重启数据库结束

怎样启动和关闭oracle数据库

# su - oracle$ sqlplus / as sysdba关闭数据库SQL> shutdown immediate启动数据库:SQL> startup也可以一步一步的起: 一: SQL> startup nmount; SQL> alter database mount; SQL> alter database open;二: SQL> startup mount; SQL> alter database open;也可以在操作系统命令上使用dbstart 和dbshut命令启停数据库。但是需要修改/etc/oratab文件,将最后一行的N 改成 Y

linux下 怎么重启oracle数据库

工具/原料 oracle数据库secureCRT或其他类似工具方法/步骤打开secureCRT,连接到数据库服务器,使用oracle用户登录系统登录Oracle: sqlplus / as sysdba关闭数据库 SHUTDOWN NORMAL启动数据库 startup参考 关闭数据库时的参数:在shutdown时可选择关闭模式:NORMAL、TRANSACTIONAL、IMMEDIATE或ABORTu2022 ABORT:在关闭之前执行的任务最少。由于此模式需要在启动之前进行恢复,因此只在需要时才使用此模式。当启动实例时出现了问题,或者因紧急情况(如,通知在数秒内断电)而需要立即关闭时,如果其它关闭方式都不起作用,通常选择使用此模式。 u2022 IMMEDIATE:这是最常用选项。选择此模式会回退未提交的事务处理。 u2022 TRANSACTIONAL:允许事务处理完成 u2022 NORMAL:等待会话断开 如果考虑执行关闭所花费的时间,则会发现ABORT的关闭速度最快,而NORMAL的关闭速度最慢。NORMAL和TRANSACTIONAL花费的时间较长,具体取决于会话和事务处理的数目。注意:在SHUTDOWN NORMAL或SHUTDOWN TRANSACTIONAL或 SHUTDOWN IMMEDIATE 这三个模式下关闭数据库,则:关闭时:执行immediate时,会回退未提交的更改;数据库缓冲区高速缓存,会写入到数据文件;会释放资源。启动时:不用恢复实例。 在SHUTDOWN ABORT或 实例错误 或STARTUP FORCE,则关闭时:修改过的缓冲区未写入数据文件;不回退未提交的更改。启动时:使用联机重做日志文件重新应用更改;使用还原段回退未提交的更改。

oracle客户端建新连接测试时提示invalid username/password;logon denied如何解觉呢

用户名和密码错误 登录被限制

在Oracle12c上添加了Scott用户,但是为什么再次进入的时候却显示invalid username/password;logon denied

应该是新建的用户是锁着的,或者你只是新建了用,没有赋connect权限,登录sys用户去看一下用户状态,再修改一下密码具体步骤:win+r 回车sqlplus / as sysdbaselect * from dba_users where user_name like "%SCOTT%"(注意大写)这里可以看到用户状体信息赋权:grant rescore,connect to SCOTT ;解锁:alter user scott account unlock;修改密码:alter user scott identified by tiger;经过这几步设置,应该就可以连了测试一下:connect scott/tiger

Oracle 根据出生日期计算年龄

months_between(trunc(sysdate,"yyyy"),trunc(c.birthdate,"yyyy"))/12

Oracle中systimestamp的问题

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.

oracle trunc()函数关于日期和时间,需要详细解答和举例?

以下 SQL 执行于 2010-10-17 22点多这个样子。不知道你看了例子以后,能不能明白。alter session set nls_date_format="YYYY-MM-DD HH24:MI:SS";Session altered.SQL> SELECT "Year" AS truncType , TRUNC( SYSDATE, "YYYY" ) FROM DUAL 2 UNION ALL 3 SELECT "Quarter" AS truncType, TRUNC( SYSDATE, "Q" ) FROM DUAL 4 UNION ALL 5 SELECT "Month" AS truncType, TRUNC( SYSDATE, "MM" ) FROM DUAL 6 UNION ALL 7 SELECT "Week" AS truncType, TRUNC( SYSDATE, "W" ) FROM DUAL 8 UNION ALL 9 SELECT "Day" AS truncType, TRUNC( SYSDATE, "D" ) FROM DUAL 10 UNION ALL 11 SELECT "Hour" AS truncType, TRUNC( SYSDATE, "HH" ) FROM DUAL;TRUNCTYPE TRUNC(SYSDATE,"YYYY-------------- -------------------Year 2010-01-01 00:00:00Quarter 2010-10-01 00:00:00Month 2010-10-01 00:00:00Week 2010-10-15 00:00:00Day 2010-10-17 00:00:00Hour 2010-10-17 22:00:006 rows selected.

ORACLE 数据库select语句出现ORA-00905: missing keyword

时间需要格式化。。。

oracle报错is not a valid date and time怎么办

oracle报错is not a valid date and time的原因是系统错误导致的,具体解决方法步骤如下:1、首先打开计算机,在计算机内找到【更改日期和时间设置】选项并单击。2、然后在界面内使用鼠标单击【更改日期和时间设置(D)...】选项。3、然后在弹出的界面内找到【更改日历设置】选项并单击。4、然后将日期格式中的短日期从yyyy/M/d修改成yyyy-M-d即可解决oracle报错is not a valid date and time的问题了。

执行存储过程的时候 oracle 已经改了时间设置还是is not a valid date and time 这个错

确定下这两个表clinic_master和outp_bill_items中visit_date的存放格式,是否为20170326这样格式的,如果确定无误,看看是否有格式非法的,比如20170332这样的,还有问题就要进一步检查语句或数据了。

怎样解决oracle报错is not a valid date and time

方法/步骤 1. 第一步,右击任务栏上的时间,选调整日期和时间(A),然后再点“更改日期和时间”进入日期和时间设置。 2. 第二步,点左下角的“更改日历设置”,然后进入区域选项。3. 第三步,将短日期和长日期的格式改为yyyy/m/d的格式,也就是说去掉星期,经过这样一改以后。再运行程序,OK!

Oracle和vm那个号虚拟机

vm号虚拟机。从通用角度来说vmware更好一些,毕竟vmware专门做虚拟化的厂家。如果你只是安装oracle产品的话virtualbox更好些。虚拟机不能实现电源随着宿主机启动和关闭,也不具备vmware服务器虚拟化或桌面/应用程序虚拟化等一整套解决方案。linux虚拟机:一种安装在Windows上的虚拟linux操作环境,就被称为linux虚拟机。它实际上只是个文件而已,是虚拟的linux环境,而非真正意义上的操作系统。但是它们的实际效果是一样的。所以安装在虚拟机上使用好。windowsXP虚拟机vmware下安装Linux 我们在实际的Windows XP中(宿主计算机)再虚拟出一台电脑(虚拟机),并在上面安装Linux系统,这样,你就可以放心大胆地进行各种Linux练习而无须担心操作不当导致宿主机系统崩溃了。

翻译短文when you are learning English,you find it not clever to put an English sentence,

学习英文的时候你会发现,翻译句子并不是单纯的把每个单词意思说句来就完事了的。就拿How do you do?这个句子来说吧,如果你去翻阅字典,然后把每个单词的中文意思都按顺序查出来,那么你得到的翻译会是什么?肯定是个错误的句子吧。语言的差异不止发音,还有别的方方面面。因此掌握词语顺序规则对学习英语而言也是很重要的。如果说话者以错误的顺序把单词说了出来,听者会很难听明白意思。有时词语顺序的改变会导致英文句子意思的改变;但有时却又不会对意思产生影响。让我们来看看两组句子吧:“她只喜欢苹果。”和“只有她喜欢苹果。”“我已经看过这部电影了。”和“我已看过这部电影。”当你学习英语时,你必须尽力去了解这门语言的实质,然后再像英语母语者那样去使用它。

Oracle数据库分区表操作方法

  在大型的企业应用或企业级的数据库应用中 要处理的数据量通常可以达到几十到几百GB 有的甚至可以到TB级 虽然存储介质和数据处理技术的发展也很快 但是仍然不能满足用户的需求 为了使用户的大量的数据在读写操作和查询中速度更快 Oracle提供了对表和索引进行分区的技术 以改善大型应用系统的性能   使用分区的优点   ·增强可用性 如果表的某个分区出现故障 表在其他分区的数据仍然可用   ·维护方便 如果表的某个分区出现故障 需要修复数据 只修复该分区即可   ·均衡I/O 可以把不同的分区映射到磁盘以平衡I/O 改善整个系统性能   ·改善查询性能 对分区对象的查询可以仅搜索自己关心的分区 提高检索速度   Oracle数据库提供对表或索引的分区方法有三种   ·范围分区   ·Hash分区(散列分区)   ·复合分区   下面将以实例的方式分别对这三种分区方法来说明分区表的使用 为了测试方便 我们先建三个表空间   以下为引用的内容   create tablespace dinya_space   datafile /test/demo/oracle/demodata/dinya dnf size M   create tablespace dinya_space   datafile /test/demo/oracle/demodata/dinya dnf size M   create tablespace dinya_space   datafile /test/demo/oracle/demodata/dinya dnf size M    分区表的创建    范围分区   范围分区就是对数据表中的某个值的范围进行分区 根据某个值的范围 决定将该数据存储在哪个分区上 如根据序号分区 根据业务记录的创建日期进行分区等   需求描述 有一个物料交易表 表名 material_transactions 该表将来可能有千万级的数据记录数 要求在建该表的时候使用分区表 这时候我们可以使用序号分区三个区 每个区中预计存储三千万的数据 也可以使用日期分区 如每五年的数据存储在一个分区上   根据交易记录的序号分区建表 以下为引用的内容   SQL> create table dinya_test    (    transaction_id number primary key    item_id number( ) not null    item_description varchar ( )    transaction_date date not null    )    partition by range (transaction_id)    (    partition part_ values less than( ) tablespace dinya_space    partition part_ values less than( ) tablespace dinya_space    partition part_ values less than(maxvalue) tablespace dinya_space    );   Table created   建表成功 根据交易的序号 交易ID在三千万以下的记录将存储在第一个表空间dinya_space 中 分区名为:par_ 在三千万到六千万之间的记录存储在第二个表空间   dinya_space 中 分区名为 par_ 而交易ID在六千万以上的记录存储在第三个表空间dinya_space 中 分区名为par_   根据交易日期分区建表   以下为引用的内容   SQL> create table dinya_test    (    transaction_id number primary key    item_id number( ) not null    item_description varchar ( )    transaction_date date not null    )    partition by range (transaction_date)    (    partition part_ values less than(to_date( yyyy mm dd ))   tablespace dinya_space    partition part_ values less than(to_date( yyyy mm dd ))   tablespace dinya_space    partition part_ values less than(maxvalue) tablespace dinya_space    );   Table created   这样我们就分别建了以交易序号和交易日期来分区的分区表 每次插入数据的时候 系统将根据指定的字段的值来自动将记录存储到制定的分区(表空间)中   当然 我们还可以根据需求 使用两个字段的范围分布来分区 如partition   by range ( transaction_id transaction_date)   分区条件中的值也做相应的改变 请读者自行测试    Hash分区(散列分区)   散列分区为通过指定分区编号来均匀分布数据的一种分区类型 因为通过在I/O设备上进行散列分区 使得这些分区大小一致 如将物料交易表的数据根据交易ID散列地存放在指定的三个表空间中   以下为引用的内容   SQL> create table dinya_test    (    transaction_id number primary key    item_id number( ) not null    item_description varchar ( )    transaction_date date    )    partition by hash(transaction_id)    (    partition part_ tablespace dinya_space    partition part_ tablespace dinya_space    partition part_ tablespace dinya_space    );   Table created   建表成功 此时插入数据 系统将按transaction_id将记录散列地插入三个分区中 这里也就是三个不同的表空间中    复合分区   有时候我们需要根据范围分区后 每个分区内的数据再散列地分布在几个表空间中 这样我们就要使用复合分区 复合分区是先使用范围分区 然后在每个分区内再使用散列分区的一种分区方法 如将物料交易的记录按时间分区 然后每个分区中的数据分三个子分区 将数据散列地存储在三个指定的表空间中   以下为引用的内容   SQL> create table dinya_test    (    transaction_id number primary key    item_id number( ) not null    item_description varchar ( )    transaction_date date    )    partition by range(transaction_date)subpartition by hash(transaction_id)    subpartitions store in (dinya_space dinya_space dinya_space )    (    partition part_ values less than(to_date( yyyy mm dd ))    partition part_ values less than(to_date( yyyy mm dd ))    partition part_ values less than(maxvalue)    );   Table created   该例中 先是根据交易日期进行范围分区 然后根据交易的ID将记录散列地存储在三个表空间中    分区表操作   以上了解了三种分区表的建表方法 下面将使用实际的数据并针对按日期的范围分区来测试分区表的数据记录的操作    插入记录   以下为引用的内容   SQL> insert into dinya_test values( BOOKS sysdate);    row created   SQL> insert into dinya_test values( BOOKS sysdate+ );    row created   SQL> insert into dinya_test values( BOOKS to_date( yyyy mm dd ));    row created   SQL> insert into dinya_test values( BOOKS to_date( yyyy mm dd ));    row created   SQL> insert into dinya_test values( BOOKS to_date( yyyy mm dd ));    row created   SQL> insert into dinya_test values( BOOKS to_date( yyyy mm dd ));    row created   SQL> mit;   Commit plete   SQL>   按上面的建表结果 年前的数据将存储在第一个分区part_ 上 而 年到 年的交易数据将存储在第二个分区part_ 上 年以后的记录存储在第三个分区part_ 上    查询分区表记录 以下为引用的内容   SQL> select * from dinya_test partition(part_ );   TRANSACTION_ID ITEM_ID ITEM_DESCRIPTION TRANSACTION_DATE       BOOKS : :    BOOKS : :   SQL>   SQL> select * from dinya_test partition(part_ );   TRANSACTION_ID ITEM_ID ITEM_DESCRIPTION TRANSACTION_DATE       BOOKS    BOOKS   SQL>   SQL> select * from dinya_test partition(part_ );   TRANSACTION_ID ITEM_ID ITEM_DESCRIPTION TRANSACTION_DATE       BOOKS    BOOKS   SQL>   从查询的结果可以看出 插入的数据已经根据交易时间范围存储在不同的分区中 这里是指定了分区的查询 当然也可以不指定分区 直接执行select * from dinya_test查询全部记录   在也检索的数据量很大的时候 指定分区会大大提高检索速度    更新分区表的记录   以下为引用的内容   SQL> update dinya_test partition(part_ ) t set em_description= DESK where   t transaction_id= ;    row updated   SQL> mit;   Commit plete   SQL>   这里将第一个分区中的交易ID= 的记录中的item_description字段更新为 DESK 可以看到已经成功更新了一条记录 但是当更新的时候指定了分区 而根据查询的记录不在该分区中时 将不会更新数据 请看下面的例子 以下为引用的内容   SQL> update dinya_test partition(part_ ) t set em_description= DESK where   t transaction_id= ;    rows updated   SQL> mit;   Commit plete   SQL>   指定了在第一个分区中更新记录 但是条件中限制交易ID为 而查询全表 交易ID为 的记录在第三个分区中 这样该条语句将不会更新记录    删除分区表记录   以下为引用的内容   SQL> delete from dinya_test partition(part_ ) t where t transaction_id= ;    row deleted   SQL> mit;   Commit plete   SQL>   上面例子删除了第二个分区part_ 中的交易记录ID为 的一条记录 和更新数据相同 如果指定了分区 而条件中的数据又不在该分区中时 将不会删除任何数据    分区表索引的使用   分区表和一般表一样可以建立索引 分区表可以创建局部索引和全局索引 当分区中出现许多事务并且要保证所有分区中的数据记录的唯一性时采用全局索引    局部索引分区的建立   以下为引用的内容   SQL> create index dinya_idx_t on dinya_test(item_id)    local    (    partition idx_ tablespace dinya_space    partition idx_ tablespace dinya_space    partition idx_ tablespace dinya_space    );

用了SLEEP CYCle记录睡眠,为什么深度睡眠比浅睡眠多,反而得分低

原因如下:  传统蓝牙设备的待机耗电量大一直是为人所诟病的缺陷之一,这与传统蓝牙技术动辄采用16~32个频道进行广播不无关系,而低功耗蓝牙仅使用了3个广播通道,且每次广播时射频的开启时间也由传统的22.5ms减少到0.6~1.2ms,这两个协议规范上的改变显然大大降低了因为广播数据导致的待机功耗;此外低功耗蓝牙设计了用深度睡眠状态来替换传统蓝牙的空闲状态,在深度睡眠状态下,主机长时间处于超低的负载循环(DutyCycle)状态,只在需要运作时由控制器来启动,因主机较控制器消耗更多的能源,因此这样的设计也节省了最多的能源;在深度睡眠状态下,协议也针对此通讯模式进行了优化,数据发送间隔时间也增加到0.5~4s,传感器类应用程序发送的数据量较平常要少很多,而且所有连接均采用先进的嗅探性次额定(Sn i f f-Subrating)功能模式,因此此时的射频能耗几乎可以忽略不计,综合以上因素,低功耗蓝牙的待机功耗较传统蓝牙大大减少。

4.5A @ 50% duty cycle, 10HZ 怎么解释

此芯片,允许4.5A电流,50%输出占空比,10HZ频率

请问开关电源中max.duty cycle 这个参数表示的是什么意思?谢谢。

字面理解是最大周期,但似乎不妥或不准,你能否给个波形图看看。

Duty Cycle:Max.10%,1 Min Continuous 求准确翻译

责任期间,最大也就10%的持续了1分钟

波形发生器 duty cycle是什么意思?

占空比。占空比就是矩形波信号每个周期内高电平时间与一个周期(高低电平总时间)的比值。

STM32 PWM输入捕获 占空比DutyCycle 为什么不稳定,波动很大??希望各位帮帮忙??

到官方下个测频的例程烧下试试,对照自己程序配置看看,在示波器下看下函数发生器有没有问题!!然后再检查是不是程序执行别的任务导致的。

100% duty cycle是什么意思

波形发生器 duty cycle是什么意思?

占空比。占空比就是矩形波信号每个周期内高电平时间与一个周期(高低电平总时间)的比值。

duty cycle是什么意思

duty cycle释义[电] 工作周期;占空度;[计][通信] 忙闲度

duty cycle怎么算

duty cycle的算法:通电时间相对于总时间所占的比例。例如:脉冲宽度1μs,信号周期4μs的脉冲序列占空比为0.25。比如说,一个电路在它一个工作周期中有一半时间被接通了,那么它的占空比就是50%。如果加在该工作元件上的信号电压为5V,则实际的工作电压平均值或电压有效值就是2.5V。假设该元件为一个电子阀门,当电路全时接通时,阀门全开;当占空比为50%时,阀门状态为半开。同理,当占空比设置为20%时,阀门的开度显然应该为20%。这样,这个阀门就可以在0%(全闭)到100%(全开)的范围内任意调节。影响集成电路取代了晶体管,为开发电子产品的各种功能铺平了道路,并且大幅度降低了成本,第三代电子器件从此登上舞台。它的诞生,使微处理器的出现成为了可能,也使计算机变成普通人可以亲近的日常工具。集成技术的应用,催生了更多方便快捷的电子产品,比如常见的手持电子计算器,就是基尔比继集成电路之后的一个新发明。直到今天,硅材料仍然是我们电子器件的主要材料。

Tough Problem,Lattice,Circles

更新1: Sorry for the typesetting 更新2: just a little correction of mistake: 1. sort by slope in DESCENDING order (but the order does not really matter because of symmetric properties) 2. sort by slope the slope of the line passing thru. O and the point 更新3: Andrew: you can wer it. it is good if this problem can be solved. but it could be solved i would still award you best wer 更新4: 1. Pick"s theorem? Brilliant. You want to pare the area of triangles P(i) O P(i+1) using 1/2absin theta and Pick"s? (<--a guess) 2. Actually this is only a part of a big problem. The big problem itself is a minmax problem. and now we are at the max stage. 更新5: 3. Yes it breaks. But what is your idea? perhaps there exists a line that is suitable to bound the points without changing the no. of point. 更新6: (supp.) 3. because the quarter circle gives the points to be considered 更新7: Please recall that Pm is the m-th point (sort by slope in ascending or descending order) in the set of points. And we"d like to find the largest angle that the line P_m O makes with P_m+1 O Working on it. Couple hints for others: 1.) Consider Pick"s theorem - I think it is relevant here. 2.) The GCD constraint is really simply removing lines with exactly same slope. 2010-06-24 13:25:20 补充: We can think of this problem as a maximin problem - for a particular point minmize by finding a point nearby that minimize the angle and maximize by finding the point that maximize the quantity above. 2010-06-24 13:25:29 补充: From this perspective - we can approach the problem this way. From a point try to find an upper bound of the minimized angle. If this upper bound is less than the one beeen P1 and P2 we are done. 2010-06-24 13:25:39 补充: By Pick"s Theorem - we have the area of the triangle = 0.5 I wonder how can we make use of this fact. It sounds like a constrainted maximization problem - find a triangle with with integer coordinates area = 0.5 with maximum angle. 2010-06-24 13:25:46 补充: kwanhimshek - if you have a simulation program can you remove the constraint that the points are in the quarter circle - does that break the conjecture? 2010-06-29 11:06:52 补充: I don"t have a plete wer yet but I want to share what I think about the problem and hopefully we can wer that together. First of all we can leverage Pick"s theorem. For all the triangles that are formed by three lattice point on the vertexs and no lattice point on the edge in interior the area must be 0.5. We can also calculate the area in a different way using vector cross product suppose the points are (a b) and (c d) respectively we have 2A = |ad - bc| = 1 We can also calculate the area in a third way in particular we have 2A = |(a b)| |(c d)| sin theta = 1 Now since sine is an increasing function therefore the larger the angle the larger the sine therefore if we want big angles we will have *** all length products. Unfortunately Pick"s theorem does not help us to eliminate all wrong triangles in particular we can have triangles with no lattice points in the interior and boundary but yet not a valid triangle (0 1)-(0 0)-(1 0) is a counter example. In fact it gives the largest possible angle = 90 degree. 2010-06-30 12:16:45 补充: I think we need more explanation here: If we join P(m) O P(m + 1) into a triangle it will be a triangle that 1) Have no points in the interior (for if there is one then there is a line with *** aller angle and P(m) and P(m+1) could not be next to each other) and 2010-06-30 12:16:49 补充: 2) Have no point in the edge (or otherwise GCD(a b) > 1 or GCD(c d) > 1) Therefore it will satisfy the Pick"s theorem let us call these right triangles. There are wrong triangles that also satisfy Pick"s theorem as I mention in the last paragraph. 2010-07-02 10:36:30 补充: I have more findings here. For ad-bc must equals to 1 and gcd(a b) = 1. We can guarentee the existence of (c d) by the extended euclidean algorithm. Suppose we get some (c d) here such that ad-bc=1 another pair of (c" d") that also satisfy the relation:: ad" - bc" = 1 ad - bc = 1 a(d"-d)-b(c"-c)=0 参考: Pick"s theorem i"ll try to understand your wer..but i"m afraid i can"t- -

【ORACLE】DDL包括哪些操作

Data manipulation language (DML) statements query or manipulate data in existing schema objects.Whereas DDL statements change the structure of the database, DML statements query or change the contents. For example,ALTER TABLEchanges the structure of a table, whereasINSERTadds one or more rows to the table.DML statements are the most frequently used SQL statements and enable you to:Retrieve or fetch data from one or more tables or views (SELECT).Add new rows of data into a table or view (INSERT) by specifying a list of column values or using asubqueryto select and manipulate existing data.Change column values in existing rows of a table or view (UPDATE).Update or insert rows conditionally into a table orview(MERGE).Remove rows from tables or views (DELETE).View theexecution planfor a SQL statement (EXPLAINPLAN).Lock a table or view, temporarily limiting access by other users (LOCKTABLE).DML statements do not implicitly commit the current transaction.(二)Data Definition Language (DDL) StatementsData definition language (DLL) statements define, structurally change, and drop schema objects.DDL enables you to alter attributes of an object without altering the applications that access the object. For example, you can add a column to a table accessed by a human resources application without rewriting the application. You can also use DDL to alter the structure of objects while database users are performing work in the database.More specifically, DDL statements enable you to:Create, alter, and drop schema objects and other database structures, including the database itself and database users. Most DDL statements start with the keywordsCREATE,ALTER, orDROP.Delete all the data in schema objects without removing the structure of these objects (TRUNCATE).UnlikeDELETE,TRUNCATEgenerates noundo data, which makes it faster thanDELETE. Also,TRUNCATEdoes not invoke delete triggersGrant and revoke privileges and roles (GRANT,REVOKE).Turn auditing options on and off (AUDIT,NOAUDIT).Add a comment to thedata dictionary(COMMENT).DDL statements implicitly commit the preceding and start a new transaction.(三)Transaction Control StatementsTransaction control statements manage the changes made by DML statements and group DML statements into transactions.These statements enable you to:Make changes to a transaction permanent (COMMIT).Undo the changes in a transaction, since the transaction started (ROLLBACK) or since a savepoint (ROLLBACK TO SAVEPOINT). Asavepointis a user-declared intermediate marker within the context of a transaction.Set a point to which you can roll back (SAVEPOINT).Establish properties for a transaction (SETTRANSACTION).Specify whether a deferrableintegrity constraintis checked following each DML statement or when the transaction is committed (SET CONSTRAINT).(四)Session Control StatementsSession control statements dynamically manage the properties of a usersession.A session is a logical entity in the database instance memory that represents the state of a current user login to a database. A session lasts from the time the user is authenticated by the database until the user disconnects or exits the database application.Session control statements enable you to:Alter the current session by performing a specialized function, such as setting the default date format (ALTER SESSION).Enable and disable roles, which are groups of privileges, for the current session (SET ROLE).Session control statements do not implicitly commit the current transaction.(五)System Control StatementA system control statement changes the properties of thedatabase instance.The only system control statement isALTER SYSTEM. It enables you to change settings such as the minimum number of shared servers, terminate a session, and perform other system-level tasks.TheALTER SYSTEMstatement does not implicitly commit the current transaction.【ORACLE】DDL包括哪些操作标签:accessfortinsubexamplerowupdateoraint

html5中div section article之间具体有什么区别

div section article ,语义是从无到有,逐渐增强的。div 无任何语义,仅仅用作样式化,对于一段主题性的内容,则就适用 section,而假如这段内容可以脱离上下文,作为完整的独立存在的一段内容,则就适用 article。原则上来说,能使用 article 的时候,也是可以使用 section 的,但是实际上,假如使用 article 更合适,那么就不要使用 section 。nav 和 aside 的使用也是如此,这两个标签也是特殊的 section,在使用 nav 和 aside 更合适的情况下,也不要使用 section 了。

--创建一张临时表,用来存在1,23,456,7890这个字符串createtabletest_20110420(strint_testvarchar2(50));--把1,23,456,7890这个字符串写入到临时表insertintotest_20110420values("1,23,456,7890");--一个sql语句查询出来selectsubstr(a.strint_test,1,instr(a.strint_test,",")-1)fromtest_20110420aunionallselectsubstr(a.strint_test,instr(a.strint_test,",",1,1)+1,instr(a.strint_test,",",1,2)-1-instr(a.strint_test,",",1,1))fromtest_20110420aunionallselectsubstr(a.strint_test,instr(a.strint_test,",",1,2)+1,instr(a.strint_test,",",1,3)-1-instr(a.strint_test,",",1,2))fromtest_20110420aunionallselectsubstr(a.strint_test,instr(a.strint_test,",",1,3)+1)fromtest_20110420a;

Oracle的substr()函数

  SUBSTR函数  VFP字符函数的一种。表示的是字符型函数。格式是:SUBSTR(<字符表达式>、<数值表达式1>[,<数值表达式2>]  函数功能:是从给定的字符表达式或备注字段中返回一个子字符串。  语法格式一:  SUBSTR(cExpression,nStartPosition [,nCharactersReturned])  其中,cExpression指定要从其中返回字符串的字符表达式或备注字段;nStartPosition用于指定返回的字符串在字符表达式或备注字段中的位置,nCharactersReturned用于指定返回的字符数目,缺省时返回字符表达式的值结束前的全部字符。  举例  STORE"abcdefghijklm" To mystring  ?SUBSTR(mystring ,1,5) 显示 "abcde"  ?SUBSTR(mystring ,6) 显示 "fghijklm"  ?SUBSTR(mystring,-2)显示“lm”  ?SUBSTR(mystrng,-4)显示“jklm”、u200d 语法格式二u200du200du200d:u200du200du200du200dSUBSTR(char A,char B,int C, int D)  这个函数主要用于字符串的运算,参数A是字符数组或是指向字符串的指针,用于接收字符串,参数B一般也为字符数组或指向字符串的指针,表示要截取字符串的地方,参数C表示从B中截取字符串的起始位置,参数D表示要截取字符串的长度,缺省时返回字符表达式的值结束前B的全部字符。  上述表达式功能可描述为:从字符串B的第C个字符处开始,截取长度为D的一串字符串,放入字符串数组A中,返回截取的字符串。  举例: ch X S[]="abcdefgh" 调用substr(X,S,4,2)后,得到的结果是:"ef"

Nuclease-Free Water与RNAase-free Water 区别?是否可以相互代替使用?

你用过invitrogen公司的产品就知道他们公司一般的产品都是,RNase free的,也就是,处理过RNA酶的水。free就是处理过的,不存在的意思。后者RNAase-free Water 主要是在提取RNA中使用,像我们用的DEPC水,就是这种。知道这是什么,相信你自己也明白,那些时候可以相互代替,那些时候不可以了吧
