Duplicate Boy
Out of all superheroes duplicate boy is the laziest. Duplicate boy
almost used his power everywhere. He used his power to do his chores and
homework, or to read a book. and finally a duplicate goes to school. He
always sleeps, eats, plays video games, read some book, and fight crime.
Duplicate boy has a lot of limitations. Duplicate boy only can make 5
copies of himself, and has to tell duplicates what to do. When he comes
to fighting crime, Duplicate boy can make copies of him and... 阅读全帖

I guess you imply that duplicate means every columns in two rows are same. I
have a need to delete duplicate rows before, where duplicate means only
unique key columns are same. (see: http://oracle-study-notes.blogspot.com/2008/06/resolve-issue-of-duplicated-rows-in.html )
Here is a good post for Oracle, but should be applicable for SQL Server too

我知道如果要pp,就一定不要让USICS找DOL要perm duplicate。
我现在不确定是不是需要pp,于是初步打算先按照non pp来申,如果本财年接下来几个
月突然EB3 B表大进(使得我PD当前)而且还被HONOR的话,我就马上pp,降级过了后,
再提485进门。
我的问题是,现在表格中,还需要不需要让USCIS找DOL要perm duplicate呢?
或者换个问法,如果我不要USCIS找DOL要perm duplicate,只让律师附一份提交perm
复印件,这样的话可以么?会不会招来RFE?还是说就干脆等算了,不pp,就request
perm duplicate?
我的PD是Aug 19,2015.
感觉无论如何,都不可能2017财年有任何戏的吧?B表再honor也没戏的吧?

+ is concatenation ; we use that a lot to find out and furthuer more, to
remove duplicate record. But, first thing first, how do you define your
duplicate is up to you.
you can use the Plus sign to concatenate string together...
Usually a table contains many, if not thousands of same first name, so, only
the same firstname&lastname&address combination together truly counts as a
duplicate.. it depends on how you define *duplicate* in your own table..

来自主题: Database版 - list duplicators in one table
我这个不是考试题阿。是我工作的一部分。
我们有个table, 我们称为 contacts, 主要是各类events和visiting,collect来的
information,同时我们因为有不少reports,供references,download,但是他们必须先
register. 所以,就不可避免地出现了duplication,需要定期清理。我今天一查,竟然
有大约8000余个duplicators,涉及16000余records. 当然其实,大多数不是真地
duplication,呵呵。比如我们有15个david smith。结果发现,一个duplication都不存
在,看上去,没有明显证据。真实的干活,跟课堂真实不一样。我只能半手工,半自动
,写一些codes,来处理这些数据,而且还要定期清理,呵呵。时间就一天天过去了。

买车的时候车主提供了title文件,标题是certificate of title,但是下面接着一行
字:
this is a duplicate certificate and may be subject to the right of a person
under the original certificate odometer mileage from original certificate.
车主说原title丢了,去年新办了一个。我查autocheck也确实是一年前办了这个title.
然后拿着这个duplicate certificate去dmv换title,工作人员也没说什么,顺利提交
了application了。
回来一想,应该问清楚一点的,万一车主找到了原来的title怎么办,我钱已经付了,
并且是给的cash,这样子会不会有问题??关键是这个duplicate certificate title
是不是具有同等效力?

来自主题: Automobile版 - urgent: new car with duplicate title?
谢谢大家回复,我们可以理解title上不是我们的名字,而是银行的名字。只是一开始搞不明白要duplicate title,因为duplicate title是丢了original title才需要的。不过后来听finance的人解释就明白了。
后来问清楚了,finance的那个人跟我说,那个duplicate title是以防original title
寄给我们的时候寄丢了。如果万一真的寄丢了,那么他们就会给我们重新申请一份,如
果三个月内我们没有通知他们说我们没收到original title的话,他们就将那份文件销
毁了。
最后终于把车买下来了,多谢大家。

也不一定是丢了。我的title就是duplicate,原因是DMV寄给我title的时候被我在拆信
封的时候不小心用刀片裁成了两半。这种title以后也不能再转给别人了,于是第二天我
就再申请了第二张。结果不出一个月autocheck上就变成duplicate title了。其实dupl
icate title跟原来的那张在纸张和印刷方式上还是有一定区别的,至少我手里的两张就
不太一样。我以前买车的时候也看到过一些车有duplicate title的记录,有些担心。其
实只要你能在DMV转得成title,一般就没什么问题。

最近看到一道题,没什么特别好的思路,请教各位大神:
Given a string s, remove duplicate adjacent characters from s recursively.
For example:
Input: "abbac"
Output: "c", first remove adjacent duplicated 'b's, then remove adjacent
duplicated 'a'.
Input: "acbbcad"
Output" "d", first remove 'b', then remove 'c', then remove 'a'.
Input: "acbbcda"
Output: "ada"
Do it with one pass over the string.

A read world application:
You use mutiple sensors to sense a same target, to increase accuracy, e.g.,
mount sensors on different directions for maximum coverage of the target. The
sensors are synchronized not to do duplicate readings. But, in reality,
duplicates still happen.
So, you don't want multiple readings of a same value.
Since all values are distinct except duplicates, how to design a hashing
function?

you can also use a bitmap (8K bytes) to detect duplicates,

table should be very small.

来自主题: Programming版 - 一道c++ 题, 找出duplicate numbers
why not directly use bitmap. Since duplicate rate <0.1%. So the maximium
duplicate occurrences will be less than 64K * 0.001 <=66. So for each number
in bitmap, I would use 7 bit to represent. So total memory consuption is
7bits * 64K =56KB. Then I can directly count the number of duplicates in
this bitmaps
In the other side, I just wonder if you use an extra Hashtable, How many
slots are you gonna use? I think it's O(n) where n is the size of the array.

这个duplicate更多是business logic上的duplicate,比如说同一个订单里不能有两个
同样的零件有重叠的日期,因为涉及到日期重叠而不是一样,所以group by可能不行吧
。我想过简单的处理这个的Logic是遍历每一个row,然后用一个exists来找其他row有没
有跟这个row有一样的parent id, tag, overlap的日期的,如果有就设置错误位,没有
就清除错误位。不过感觉这样不会很快,可能会有更好的方法。
另外要求sqlserver和oracle都能用,只能是ansi sql了,又麻烦了点。

了。
由于之前移民律师协会有消息指出相关规定包括同个一雇主申请一般及美国硕士学位以
上H-1B 的申请“可能”不列入Duplicate 之列,这也让大家最关心的问题。
在OMB Clear 之后就等待相关部门最后签名定案后送联邦公报上公布,由于4月1日移民
