About pre-defined function

Respected sir,
My name is kiran, I’m studying 3rd year B.Tech. Sir, I have written one predefined function in java which was not present yet. This function performs mathematical operation, calculating “DET” of given matrix of any order. Can this function be included in your coming versions of java? Give me reply sir.My email addresses are:
[email protected]
[email protected]
If you don't know about it,please exact address for whom to contact.
Thank you,sir.
Yours sincerely,
Kiran.

It's pretty cheeky to suggest that your little method
is worthy of inclusion in Java's core API, isn't it?Oh let him take part in the community process... what harm will it do? We all know what the result will be but he can feel a part of it. Nothing wrong with that I don't think and I am not sure that interest is neccessarily cheek.

Questions about user-defined functions

Hello all,
I've got some questions about user-defined function in a message mapping:
1) How can I get the current date/time in format yyyy-mm-dd hh:mm:ss ? What is the java code for this?
2) I want to use the StreamTransformation constant TIME_SENT, only this is not in the right time-zone.
It is GMT and it should be CET (1 hour difference). How can I convert this in Java?
Can somebody help me with this?
Thanks in advance.
Kind regards,
Marco van Iersel

Hi Marco,
If the date format is fixed as you have mentioned,please use this:
                                String test = "2009-03-27 23:15:30";
          String test1 = test.substring(11,13);
          if(!test1.equals("23"))
          int a = Integer.parseInt(test1);
          int b = a+1;
          System.out.println("b"+b);
          String c = Integer.toString(b);
                                test = test.substring(0,10)+" " + c + test.substring(13,19);
                                return test;
          if(test1.equals("23"))
          test = test.substring(0,10)+ " 00" + test.substring(13,19);
          return test;
                                else return "";
Kindly let me know if this works.
Thanks.

About user defined function in user defined rule

Hi,
I am wondering if I can use a user defined function in a user defined rule in oracle sem.. I've seen examples of user defined function used in sparql query filter clause in that dev. guide. However, I don't know if I can define a function in oracle sem. database and use it in the rule body or head. For example, I want to define a duration function that calculate the date difference between two dates. Then, I want to define a rule like this: event1 :has_start_date d1 and event1: has_end_date d2 and duration (24, d1,d2) then event1:date_satisfiable "yes". Does oracle support this kind of rule? Thank you very much.
Hong

Hi Hong,
The user defined rules are quite similar to a CONSTRUCT SPARQL query, where the FILTER clause is implemented in SQL.
I think we have already written rules like you want :
You have to write a PL/SQL FUNCTION that returns a NUMBER (not a BOOLEAN, think you are in SQL) :
FUNCTION DURATION(HOURS INTEGER, D1 VARCHAR2, D2 VARCHAR2) RETURN INTEGER
IS
BEGIN
     IF(.................)
        THEN RETURN 1;
        ELSE RETURN 0;
     END IF;
END;
Maybe you will have to GRANT EXECUTE ON DURATION TO MDSYS.
Then include the following in the FILTER clause of the Rulebase "[owner].duration (24, TO_CHAR(d1),TO_CHAR(d2)) = 1"
Hope this helps.

About User defined Functions

Hi,
Do anyone know what are user defined functions .. and what's the procedure to create a user defined function in sql or pl/sql ??
Regards

Is this Seshu or someone else asking with his login? The reason for this is earlier there was a post from some Param Reddy from Kurnool asking with his login.
If it is Seshu himself, I've seen you using the word 'function' a couple of time earlier.
Re: Comma separation
and
Re: Data Hiding
If you go and see in SQL Reference, you find two types of functions. SQL built-in and User-defined.

Regarding sqlserver user defined functions

Hi,
How to write user defined functions dynamically?
Please help me in any situation

Hi Bellam,
You post same question 2 times. Please avoid this practice on Forum, I
have merged the same thread into this thread.
As other post, dynamic SQL is not allowed in user defined functions (UDF), however, you can execute dynamic SQL store procedure with parameter. A user-defined function takes zero or more input parameters and returns either a scalar value or a table. There
is different between user-defined stored procedures and
user-defined function. User-defined functions do not support output parameters.
For more information, you can review the article about User-Defined Functions(UDF).

How can I use Seeburger java functions on SAP XI's user defined functions?

Hi All,
As my title implies; how can I use Seeburger java functions on SAP XI's user defined functions? I've tried searching over the net in tutorials regarding this topic but I failed to find one; can someone provide me information regarding my question? thanks very much.
best regards,
Mike

Hi Mike !
You should check your documentation about which java classes you need to reference in the "import" section of your UDF. And also deploy the java classes into the java stack or include them as a imported archive in integration repository...it should be stated in the seeburger documentation.
What kind of functions are you trying to use?

Matias.

User Defined Function VS join - Performance....

Hi All,
while linking the mulitple table and getting the values ....which one is the best ?
Joining or User defined function.....
single row function
select a.name , get_salary(empid) from emp a;
Note : get_salary function will return the salary from salary tables.
Using joins
select a.name ,b.salary from emp a, salary b
where a.empid=b.empid;
which is the performancewise best ?
also if you give any related document also fine.
Thanks in advance.
Edited by: BASKAR NATARAJAN on Jan 6, 2011 10:09 PM

Don't use such functions for joins. The function itself has to query the salary table. It will run the query against the salary table separately for each row that it reads from the emp table. You will end up with multiple recursive calls and possibly inconsistency in the output. (Imagine what would happen if the salary table were updated and commited while this query was running -- some rows would have been read with the pre-update values and others with the updated values).
Specifying the join in the query ensures that a single SQL call is executed and provides read consistency across all the rows it reads. And it is much faster, being one single parse and execute.

User-defined function in FILTER clause

hi,
can i create the user-defined functions and use them in the FILTER clause in the sem_match function? there are some built-in functions for the FILTER clasue. however, only one function (DATATYPE(literal)) support for date/time in the built-in functions. i want to implement some user-defined funcitons in the FILTER clause which can check time intervals in ontology. there are some functions about valid time in the WorkSpace Manager such as WM_OVERLAPS, WM_CONTAINS,WM_MEETS, etc. so, can i write some functions using the these valid time functions in WM and use them in the FILTER clause? thanks a lot in advance.
hong

Hi Hong,
You don't need user-defined functions to do time interval comparisons. You can directly compare xsd:dateTime values with the built-in comparison operators: <, >, =, !=, <=, >=
For example, the query pattern below could find events that happened during event1 if we have data such as:
:event1 :startTime "2013-01-01T03:15:00Z"^^xsd:dateTime .
:event1 :endTime "2013-02-01T02:15:00Z"^^xsd:dateTime .
:event2 :startTime "2013-01-11T14:15:00Z"^^xsd:dateTime .
:event2 :startTime "2013-01-14T12:15:00Z"^^xsd:dateTime .
SELECT ?e2
WHERE
{ :event1 :startTime ?e1_st; :endTime ?e1_et .
?e2 :startTime ?e2_st; endTime ?e2_et .
FILTER (?e1_st < ?e2_st && ?e2_et < ?e1_et) }
In general, it is trivial to convert interval relations such as meets and overlaps to conditions on start and end times.
Hope this helps.

you advanced user defined functions are now known as
Enhanced Functions (Cache = Context or Cache = Queue)
From Help -
+Features
Depending on which values are available in the cache for a user-defined function, different functions are available:
·        Simple Functions (Cache = Value)
This function type can process individual input values of a field for each function call. Therefore, simple functions expect strings as input values and return a string.
·        Enhanced Functions (Cache = Context or Cache = Queue)
This function type can process multiple input values of a field for each function call. Before you call the function, you can either import all the field values of a context or the whole queue for the field in an array.+

How to export multiple copies reoprts based on parameters and with pre-defined naming

Hi All:
I have a problem of using SSRS 2012, we have multiple clients and they wanted us to deliver the pre-defined excel reports to different branches based on selecting the "branch name" parameter, also they have a naming rule for the excel
report file.
We cannot use the subscription as they need to do it in one batch and upload to an FTP file, therefore we are doing this manually for over 300 reports. Is this a convenient way to generate them in one batch as well as customising their file names?
Thanks a lot for your help.
Cheers
Johnny

Hi JohnnyKahWang,
As per my understanding, there are multiple clients, you want to deliver reports to clients according to branch name parameter, and naming the excel file according to the rule. If that is the case, we can use data-driven subscription to achieve your goal.
Reporting Services provides data-driven subscriptions so that you can customize the distribution of a report based on dynamic subscriber data. Data-driven subscriptions use query results to determine the recipients of the subscription, delivery settings,
and report parameter values. At run time, the report server runs a query to get values used for subscription settings. We can use the Create Data-driven Subscription pages to define the query and assign query values to subscription settings. For detail information,
please refer to the following steps:
1. Open Report Manager, and locate the report for which you want to create a data-driven subscription.
2. Hover over the report, and click the drop-down arrow.
3. In the drop-down menu, click Manage. This opens the General properties page for the report.
4. Select the Subscriptions tab, and then click New Data-driven Subscription.
5. Choose a method of delivery, then select data source for the subscription.
6. Specify a query that retrieves subscriber data like below:
CREATE TABLE Name (
BranchName varchar(20),
ExcelFileName varchar(20),
Email_to varchar(50)
INSERT INTO Name values
('Branch1', 'Name1', '[email protected]'),
('Branch2', 'Name2', '[email protected]'),
('Branch3','Name3', '[email protected]');
IF we chose Windows File Share delivery extension, we can define path in the query.
7. Specify delivery extension options like below:
8. Specify report parameters to BranchName.
9. Specify when the subscription is processed, then click Finish to save the configuration.
For more information about Data-driven Subscription, please refer to the following documents:

If you have any more questions, please feel free to ask.

User defined function to find difference between dates

format of dtActivityStartDate/dtActivityFinishDate: 2010-09-17 14:50:51.150
usdFuncTimeCalc (vcActivityName,dtActivityStartDate, dtActivityFinishDate) -- user defined function
i need to calculate time elapsed for that type of activity following are the rules:
(If Process Request is the activity)
Working Days: Monday through Saturday
Hours of Operation: 9AM – 5PM
only working hours of day need to the counted like for example if it is sep 15 11 Am is dtActivityStartDate & Sep 17 is dtActivityFinishDate is 10 Am. then time elapsed is 11am to 5pm on sep 15 , 9 to 5 on sep 16 & 9 to 10 on sep 17 so total should be
6+ 8 + 1 = 15 hours + minutes.
format of date time: 2010-09-17 14:50:51.150
vcActivityName = Process Request
Don't worry about process request...

I hv modified the code to make it more generic inorder to suit any timings (customizable) from Monday - Saturday.
declare
-- ** b u s i n e s s _ h o u r s **
-- business_hours returns the number of work houts (9 am through 5 pm,
-- Monday through Saturday) between in_start_dt and in_end_dt.
-- If in_start_dt > in_end_dt, the results will be <= 0.
-- Holidays are not considered.
in_start_dt DATE := to_date('15-SEP-2010 11:00:00','DD-MON-RRRR HH24:MI:SS');
in_end_dt DATE := to_date('17-SEP-2010 10:00:00','DD-MON-RRRR HH24:MI:SS');
d NUMBER; -- Hours of either start_dt or end_dt after midnight
end_dt DATE := GREATEST(in_start_dt, in_end_dt); -- In case dates were in wrong order
return_val NUMBER; -- Total number of working hours
start_dt DATE := LEAST(in_start_dt, in_end_dt); -- In case dates were in wrong order
start_time number := 9;
end_time number := 17;
BEGIN
WITH all_days AS(
 SELECT start_dt + LEVEL - 1 AS a_dt
 FROM dual
 CONNECT BY LEVEL <= 1 + TRUNC(end_dt) - TRUNC(start_dt))
 --SELECT SUM(12)
 SELECT SUM(end_time-start_time)
 INTO return_val
 FROM all_days
 WHERE TO_CHAR(a_dt,'Dy','NLS_DATE_LANGUAGE = ''ENGLISH''') NOT IN ('Sun');
dbms_output.put_line('Return_Val_1 : '||return_val);
-- Adjust hours from start_dt, if necessary
IF TO_CHAR(start_dt, 'Dy', 'NLS_DATE_LANGUAGE = ''ENGLISH''') NOT IN ('Sun') THEN
 -- Calculate nbr of hours passed from midnight
 d := 24 * (start_dt - TRUNC(start_dt));
 dbms_output.put_line('d:'||d);
 IF d >= end_time THEN -- d has passed 5 PM (end_time)
 -- Don't count start_dt if it has passed the closing hours
 return_val := return_val - (end_time-start_time);
 dbms_output.put_line('if-d:'||return_val);
 ELSIF d > start_time and d < end_time THEN -- d has passed 9 AM but less than 5 PM
 -- Don't count the part of start_dt which has passed the opening hours
 return_val := return_val - (d - start_time);
 dbms_output.put_line('else-d:'||return_val);
 END IF;
END IF;
dbms_output.put_line('');
dbms_output.put_line('Return_Val_2 : '||return_val);

 IF d <= 9 THEN -- d < 9 AM
 -- Don't count end_dt itself
 return_val := return_val - (end_time-start_time);
 dbms_output.put_line('if-d:'||return_val);
 ELSIF d > start_time and d < end_time THEN -- d > 5 PM
 -- Don't count part of end_dt
 return_val := return_val - (end_time - d);
 dbms_output.put_line('else-d:'||return_val);
 END IF;
END IF;
dbms_output.put_line('');
dbms_output.put_line('Return_Val_3 : '||return_val);
IF in_start_dt > in_end_dt THEN
 return_val := -return_val;
END IF;
dbms_output.put_line('');
dbms_output.put_line('Return_Val_4 : '||return_val);
END;Plz note the following points of the code :
1) You'll need to convert it a function, I just made it a declare..begin..end; block.
2) I hv used the same timings for start & end as you hv mentioned.
3) The 2 variables "start_time" and "end_time" take the opening & closing business hours respectively in a 24 hour format.
4) You might want to remove the DBMS_OUTPUT ... stmts which I had added for debugging.
It was an interesting code block to analyze ... :-)

User-defined function(java)

hi expects,
how to write user defined finction in javain meesage mapping.please help me.

Hi Rohit,
In order to create UDFs, you need to have a basic idea about using Core Java. Also, based on the kind of functonality of the code, you will need to know if you require any extra jar files.
To create a UDF, all you need to do is click on LHS icon in the graphical mapping editor. Also, keep in min that the input and otput of a udf is always in strings.
To test your functions, you can either use the test tab present in the mapping editor or you can even use the following editor(blog by Sravya):-
/people/sravya.talanki2/blog/2006/07/24/integrating-java-editor-in-xi-integration-stack
I think info will be enough for you to start off with creating and using UDFs:)

Writing use defrined functions in XI is quite simple. Create a simple UDF, give the import parameters and then just go ahead with the logic coding and then return the output from the UDF.
Just remember that all inputs and outputs to an UDF are always Strings.

Making a User Defined Function for Mapping in XI

Hi folks..
I knw how to make User defined Function in XI,
i was wondering about can we have any room for making a function for Initializing Purpose, which intializes few fields in source Message to some Global variables, and later we can use these Global Variables to set the the Target field
My Doubt is this...
i have Source & target Structure like this Structure like this....
SOURCE TEST DATA IS...
Parentsrc
 child1src a
 child2src b
 child3src c
 child4src hi
 child4src hello
 child4src hey
(On the basis of instances of child4src the istance of the Parentdst will be generated)
TARGET DATA SHUD BE LIKE THIS....
Parentdst
 child1dst a
 child2dst b
 child3dst c
 child4dst hi
Parentdst
 child1dst a
 child2dst b
 child3dst c
 child4dst hello
Parentdst
 child1dst a
 child2dst b
 child3dst c
 child4dst hey

Hi
You have to modify your target structure:
Source
Parentsrc
child1src a
child2src b
child3src c
child4src hi
child4src hello
child4src hey
Target
root
Parentdst
child1dst a
child2dst b
child3dst c
child4dst hi
Parentdst
child1dst a
child2dst b
child3dst c
child4dst hello
Parentdst
child1dst a
child2dst b
child3dst c
child4dst hey
</root>
Now map like this:
child4src -
Parentdst
child1src--|
child4src--| UseOneAsMany -- Splitbyvalue --- child1dst
child4src--|
child2src--|
child4src--|UseOneAsMany --Splitbyvalue --- child2dst
child4src--|
child3src--|
child4src--| UseOneAsMany -- Splitbyvalue --- child3dst
child4src--|
child4src -- SplitbyValue -- child4src.

Java class within user defined function

Hi all,
in order to have a JDBC-lookup java function "globally" in XI i created a java class and imported it to XI as an imported Archive (i have to do the lookup within a mapping). I then can include the class to a user defined function. However the problem is now that this works fine within one Software Component Version but when i want to use it in several SWCV i have to import the jar to every SWCV. My question is therefore if anybody has already had this problem and if there is another possible solution - maybe deploying the class to XI using SDM?
Thank you for your thoughts.
Mathias

hi Markus,
>>>>My question is therefore if anybody has already had this problem and if there is another possible solution - maybe deploying the class to XI using SDM?
if you do that then you'll have to remember about it
every time you import a new SP or upgreade your XI
this is not standard so SAP may always overwrite it
and your interfaces will stop working
consider importing it for every SWCV
