Calculate similarity between 2 strings

Hello,
In my search help, I need to rank my result according to the similarity of my input parameter.
Ex : Input parameter = TOTO
My result :
1- TOTO
2- TOT
3- TOTO NEW
Do you know a function or a method to calculate the similarity between 2 strings?
I implemented this levenshtein algo [http://en.wikibooks.org/wiki/Algorithm_Implementation/Strings/Levenshtein_distance#Abap] but, the result is not appropriate.
Thanks in advance.
Best regards,
Xavier.

distance - Similarity Function finally arrived with release 7.02 . Please refer to http://help.sap.com/abapdocu_702/en/abendistance_functions.htm

How to calculate hours between two dateTime node in BPEL.

In my BPEL there's a requirement need calculate hours between two dateTime type..
I tried 2 solutions, both of them failed:
1. use xslt calculate duration(xml type, like PT12H) between two dateTime, and then use embedded java code to get the hours.. The problem is : I need to parse the xml duration format...(like this real one: -P80DT17H47M36S....), and to parse it in java , maybe have the same problem with solution 2..
* [Subtracting 2 dateTime values into a duration using XPath 2.0|http://blogs.oracle.com/rammenon/2007/07/subtracting_2_datetime_values.html]
2. use embed java code, but it seems we can't use some class in embedded java code:
my code(input begin, end both dateTime in xml. output: diff, int in xml):
1 System.out.println("\n\nTimeTestBegin");
2 String begin=getVariableData("begin").toString();
3 String end=getVariableData("end").toString();
4 System.out.println(begin+"-----"+end);
5 //Class c1=Class.forName("javax.xml.datatype.XMLGregorianCalendar");
6 //Class c2=Class.forName("javax.xml.datatype.DatatypeFactory");
7 //System.out.println(c1.getName());
8 //System.out.println(c2.getName());
9 javax.xml.datatype.XMLGregorianCalendar beginTime = javax.xml.datatype.DatatypeFactory.newInstance().newXMLGregorianCalendar(begin);
10 javax.xml.datatype.XMLGregorianCalendar endTime = javax.xml.datatype.DatatypeFactory.newInstance().newXMLGregorianCalendar(end);
11 long diff=beginTime.toGregorianCalendar().getTimeInMillis()-endTime.toGregorianCalendar().getTimeInMillis();
12 setVariableData("diff",String.valueOf(diff/1000/3600));
13 System.out.println("DIFF======"+diff/1000/3600);
14 System.out.println("TimeTestEnd");
it's said can't compile java class, but can't find the detail error, I think the problem is how to import java class to embedded java code activity(use full package name like above code don't work), when I remove line 9-13, no compile error..
BTY: Jdeveloper is a IDE support java, but why the embedded java activity's edit window only have a simple "java code" editor, too simple that it can only edit you code snippet...
3.There's another sulotion: extend BPEL xpath functions(add a new function), but in my project, modify BPEL server(soa server)'s config file is not allowed..
Anyone know easy solution to my problem?
Thanks.

Hi, All,
I found the cause. Sorry, it's my mistake..
below line have a DatatypeConfigurationException:
javax.xml.datatype.DatatypeFactory.newInstance()
When I test my java code snippet, I coped the code snippet to one of my java class in eclipse, and put it in a method to check if there's compile error, but I didn't notice there's a "throws Exception"...
the final java code snippet for test is :
input: begin dateTime
input: end dateTime
output: diff int, how many hours in (begin-end)
try{
System.out.println("\n\nTimeTestBegin");
String begin=getVariableData("begin").toString();
String end=getVariableData("end").toString();
System.out.println(begin+"-----"+end);
javax.xml.datatype.XMLGregorianCalendar beginTime = javax.xml.datatype.DatatypeFactory.newInstance().newXMLGregorianCalendar(begin);
javax.xml.datatype.XMLGregorianCalendar endTime = javax.xml.datatype.DatatypeFactory.newInstance().newXMLGregorianCalendar(end);
long diff=beginTime.toGregorianCalendar().getTimeInMillis()-endTime.toGregorianCalendar().getTimeInMillis();
setVariableData("diff",String.valueOf(diff/1000/3600));
System.out.println("DIFF======"+diff/1000/3600);
System.out.println("TimeTestEnd");
}catch(Exception e){
e.printStackTrace();
}

Need Help to calculate difference between times

Hello everyone,
I have two fields which just stores the time in 24 hour format ex: 08:00 and 20:00 now I want to calculate difference between the two times
Kindle help me
Thanks for your help
Thanks
Ravi

Are your fields of varchar2 datatype or...?
Is 08:00 the start time or 20:00?
Date arithmetic is pretty simple in Oracle if you use the right datatype.
See:

What's the difference between String() - as String - toString();

Hello,
I'm wondering what's the difference between this 3 ways of getting around.

There is a great difference between String(), as String and toString() methods.
String(param) -- the more general and safe method.
Returns "null" (string!) if param is null;
Returns result of param.toString() method if it is defined in class;
Returns string representation of the param (returns "[object Object]" if param is Object);
param asString --
Returns string if param is a type of String;
Returns null otherway (if param is custom class, int or other type);
param.toString() -- call of toString() member function
throws an exception if param is null;
compile-time error if toString() method is not defined in param (if your custom class do not have or inherits this function);
returns result of toString() function
Exists also ""+param and param+"" ways. They are similar to ""+String(param) and String(param)+""
Pay attention:
var ss:String = null;
trace(String(ss)==(ss as String)); // Returns false as "null" not equal to null

What is the difference between string != null and null !=string ?

Hi,
what is the difference between string != null and null != string ?

Like you've presented it, nothing. There is no difference and neither is the "better option".

What is the difference between String Constant and Empty String Constant

What is the difference between string constant which does not contain any value and the Empty string constant?
While testing a VI which contain a normal string constant in VI analyzer, it gives error to change string constant with the empty string constant?
Please Reply

Prabhakant Patil

Readability.
Functionally, they are the same. From a coding standpoint, the Empty String Constant is unambiguous.
It is empty and will always be; good for initialization. Also, because you can not type a value into and Empty String Constant, someone would need to conciously replace it to set a 'default' value that is something other than NULL.
Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T

Calculate distance between Latitude and Longitude

Hi All,
I have one Latitude and Longitude points. I need to calculate distance between them.
Right now we are using HAVERSINE formula but the query takes longer time to complete.
Reference: http://www.movable-type.co.uk/scripts/latlong.html
Please assist on this.
Thanks in advance.

Check this link...
http://www.mrexcel.com/forum/excel-questions/202255-calculating-distance-between-two-latitude-longitude-points.html
I never did this before, but gave it a try using the formula mentioned in that link..
Data:
                   Lat                      Long                               R = 6,371 (Radius of earth (approximated))
Origin:        44.844263(B2)      -92.914803(C2)
Destination: 44.822075(B3)     -92.912498(C3)
Formula used:
A: =SIN(ABS(B3-B2)*PI()/180/2)^2+COS(B2*PI()/180)*COS(B3*PI()/180)*SIN(ABS(C3-C2)*PI()/180/2)^2
B: =2*ATAN2(SQRT(1-A),SQRT(A))
C: =R*B                  ---> DISTANCE!!!!
WITH t AS
        (SELECT POWER (
                   SIN (ABS (44.822075 - 44.844263) * ( (22 / 7) / 180 / 2)),
                   2)
                + COS (44.844263 * ( (22 / 7) / 180))
                  * COS (44.822075 * ( (22 / 7) / 180))
                  * POWER (
                       SIN (
                          ABS (-92.912498 - (-92.914803))
                          * ( (22 / 7) / 180 / 2)),
                       2)
                   E2
           FROM DUAL)
SELECT (2 * ATAN2 (SQRT ( (1 - E2)), SQRT (E2))) * 6371
FROM t;
Check if this gives correct values... (I did not verify this properly.. ) And this is faster in my opinion..
Please post your code for better suggestions from volunteers...

How to calculate days between 2 dates excluding public holidays over SAP ?

Hi
Have a universe over SAP data. Trying to calculate days between 2 dates. SAP holds Public Holiday data in various tables e.g Thol and data is updated via scal. Using my univeres as a source I want to run reports for different countries so need to have various bank holidays not just UK. In SAP function modules handle this. Has anyone designed a solution to cater for this situation in a universe ?
Thanks in advance
M

Hi,
I assume you mean SAP R/3 (ECC) when you write SAP and SAP BW.
Are you using BW? If so, I would load the data into SAP BW, create a query using customer exit variables and build your universe on top of that...

Adding white spaces between strings during concatenation in JSTL

Please provide a way to add white space between strings during concatenation in JSTL.
I tried the following.
eg:
<c:set var="even_odd" value="odd">
<c:out value="first ${even_odd}"/>
I want the output string as "first odd ".
Moreover i am using the above value for generating the class attribute of a row of a table like
<tr class=<c:out value="first ${even_odd}"/>>
while printing the value of <c:out value="first ${even_odd}"/> in the page,i am getting correctly as i needed as "first odd".
But while taking the code of the page while rendering by the browser, it is showing like
<tr class="first" odd="">
I think the white space is the problem.
Please provide any solution or hint.

<tr class=<c:out value="first ${even_odd}"/>><tr class="first ${even_odd}">

Is there any Similar between Class.forName() and new operator ???

Plz tel me is there any Similar between Class.forName() and new operator ??? i have been asked this ques in interview

You probably should have used the other thread:
http://forum.java.sun.com/thread.jspa?threadID=792678
To add a little confusion to the matter...Class objects are in fact objects. They're objects representing classes. So, in a sense, I guess, you could say they're similar -- in each you get an object. But in practice Class objects and all other objects should be considered semantically different unless you're doing some pretty unusual stuff. Also Class.forName is more of a factory method than a constructor.

What Are the Differences Between String and StringBuffer?

Both String and StringBuffer are final classes. StringBuffer grows in size dynamically. Could people help to detail other differences between String and StringBuffer?

String is immutable. In other words, once it is made, the contents of that instance of String cannot be changed (easily). The size and characters cannot be changed, and code can take advantage of this fact to optimize space. Also, once you have a reference to a string, you do not need to worry about it changing at all, so you can eliminate constant tests to verify things such as size in another class that may want to hold onto the string.
StringBuffer, as you noticed, can change dynamically. While this provides flexibility, it cannot be optimized and assumptions cannot be made as with strings. If a class holds a reference to a StringBuffer that it does not own, there is a possibility that it may change things such as size when the class tries to use it later. StringBuffer is also less efficient in handling space then an equivalent String. The character array to hold a String is exactly the length to hold all the characters. StringBuffer, on the other hand, adds a 16 character buffer of array space for possible expansions. Also, the size of the internal array doubles when its internal capacity is exceeded. So, unless you explicitly maintain the size, a StringBuffer will take up more memory then an equivalent String, and if your program needs thousands of instances of Strings (which is not uncommon), that space can add up.
I hope this helps clarify some things for you.
