发帖数: 41 | 3 Hi,
I can do this in sql server -
select * where cln1 like '%(%)%'
however, if I want to delete the characters between parentheses, I can't use
replace( cln1, '(%)','').
Anyone knows how to do it?
Thanks a lot! |

What is the logic in oracle 10g+ for this please? |

发帖数: 336 | 5 我现在有一份文件, 含有德国字母, 比如a 上边加2个点. 我用insert语句加入数据库
的时候, 可以正常显示为 a 上边加2个点. 但是用ctl load数据, 该字母居然显示为"?
".
database的这个column 设定是 varchar2(100).
试过改成 varchar2 (100 char), 不灵.
数据库本身不能改变character set, 公司不让.
向高手们求助, 该咋办? |

no ( unless you hit the enter key
at least not in vi and emacs
EOF (end of file) is not a character.
So if you only type a in a new file, the there is only an a in this
file and nothing else. |

The "Chinese XML Now!" project at Academia Sinica, Taipei,

your XML document into UTF-8 and use any XML software. |

发帖数: 6 | 28 Hello,
I'm borrowing my friend's ID to post this question.
This is about application for determination of moral character for bar
examination. On the application form, it requires a Certificate of Good
Standing be submitted for each jurisdiction into which the applicant has been
admitted to practice law. I passed Chinese bar many years ago. If you have
similar experience when you applied the bar, could you please let me know how
and where to get such a document?
Thanks a lot. |

发帖数: 688 | 30 If you look closely, you should notice that I used regex for the splitter.
That is, either space or \n will be recognized. I tried the following and
it worked. Please do copy and paste to make sure you do not miss the
invisible space character.
> x="a b\nc d"
> strsplit(x,"[ \n]")
[[1]]
[1] "a" "b" "c" "d" |

发帖数: 2836 | 35 any easy proc to get the number of missing values of all the character

发帖数: 539 | 36 that's right -- i only used on numeric values and thought it would be the
same for character values :( |
|
b******e
发帖数: 539 | 37 then you can use a data step -- you need to know how many character
variables you have and their sequence in advance, which should be easy.
then:
assume you have 100 char variables:
data one (keep=count1-count100);
set xxx end=last;
retain count1-count100;
array char(*) _character_;
array count(100);
do i = 1 to dim(char);
count(i) = count(i) + missing(char(i));
end;
if last then output;
run; |

发帖数: 264 | 38 想用简单的方法，我用过first做numeric变量，
但是似乎没有说可以做character的。
var acct target
aaa 1234 dog
aaa 1266 cat
bbb 2234 rat
就是想看同样的var，不同的acct，有什么样的target组合。
我的想法是，
data one;
set sample;
by var acct;
retain A;
format A $10.; informat A $10.;
if first.var then A=target;
else A=A||target;
run;
我想出来的是，
var A
aaa dogcat
aaa dogcat
bbb rat
但是结果是
var A
aaa dog
aaa dog （cat没有加上去）
bbb rat
因为不是macro，所以我理解之前的record没法记录后来的
record的值，可是如果last的那个record记录了之前的
字符串，那也成了，可是这里它只记录first的字符串。。。
哪位高手指点一下？
多谢哈！ |
