Determine Element maxLenght in User-Defined Function

Hi,
I have the problem, that I have to fill up several fields with leading 0. I wrote a User-Defined Function for this. But the function doesn't know how long this element is, so I have to give the function the length of the element.
Is it possible to determine the length of the current element in an extended User-Defined Function
Yours
Thomas

Hi,

That function will only give me the actual lenght of the input element, what I need is the max lenght of the target element...

How can I use this function to add leading zeros?
"'000'#" ? But there I have to do this for every element

Well I have this function. But I am looking for way to the safe the second argument ;o)
Thank you all for your help

Accessing container element in the User Defined Function

Hi All,
I am accessing a container element in the user defined function.
But it is not working. Actually i want to split a message(1800 records) into a batch of 200.
But it goes in a infinite loop.
Please can you tell me where i am wrong.
Smita
The code is :
public void SplitMsg(String[] a,ResultList result,Container container){
Object container1;
String counter;
int i,j=0;
container1 = container.getParameter("value");
if( container1 == null){
counter = "0";
else {
     counter = container.toString();
     j = Integer.valueOf(counter).intValue();
for ( i = j ; i <= j + 199 ; i++){
     if ( i >= a.length){
          container.setParameter("value","9999999");
          break;
     result.addValue(a<i>);
     j += 200;
     counter = Integer.toString(j);
     container.setParameter("value", counter);

Here is another way to accomplish what you wanted.
For the target mapping, use this sequence for mapping
Source element -> removeContext -> Your User-defined Function -> Target Element
When defining User-Defined Function, select "Cache Queue" option.
Since you are using removeContext before calling the UserDefined function, your input to the user defined function will be a String array without ResultList.CC.
Now manipulate the array the way you want it, and build the ResultList result.
After every 200 records, use method
void addContextChange().
This will insert the ResultList.CC at the appropriate places.
Use Display Queue in the Mapping Editor to see the debug values.

Access Imported Archive in User Defined Function

Hi!
I want to access a XML file in an user defined function in a message mapping. The XML file is included in an imported archive. I need the information out of this XML file for configuring an extended receiver determination.
Does anyone know how to solve this?
Best regards,
Daniel

Hi Krishna,
a property file will be a solution but is has to be stored in the filesystem. In my scenario I prefer a file (not neccessary xml) which is editeable in the IR.
I tried something in this way (just for testing):
try {
     DocumentBuilderFactory factory = null;
     DocumentBuilder builder = null;
     Document document = null;
     Element element = null;
     factory = DocumentBuilderFactory.newInstance();
     builder = factory.newDocumentBuilder();
     document = builder.parse(Container.class.getResourceAsStream("routing.xml"));
     element = (Element)document.getElementsByTagName("BUSINESS_SYSTEM").item(0);
     return element.getNodeValue();
} catch (Exception e) {
     return "Crash: "+e.getMessage();
But it crashes, because the resource "routing.xml" cannot be found. I tried to add the namespace or the name of the imported archive or both as prefix, but it don't work. How can I find out under which address/url I can open the xml document?
Best regards,
Daniel

User Defined Function (UDF) help required. Pls advice urgent.

Hi ,
CRM -- XI (UDF) -- Socket Connection
Now in User Defined Function (UDF) of Message Mapping I will open Socket Connection.
Send CRM XML request to socket and get XML response from Socket and then map to some system.
Can I write Java Class code in User Defined Function (UDF) of Message Mapping instead of Java Mapping in blog below?

Henry,
Do you have a structure for your response...if you do then you can do extended reciever det with sync/async..shouldent matter, i just tried it and i dont get any error.
in your reciever determination..Check the box for standard rec det then add your first condition..of the value of a field to true..then send to A..
then you select add condition..and add for second reciever..that should be it, you shouldent need a bpm for such a simple scenario..it definetly is an overkill.

Using a User Defined Function as a constraint within a temporary table.

Hello,
I am trying to create a temp table that uses a UDF in a constraint. I'm getting the following error message
Msg 4121, Level 16, State 1, Line 1
Cannot find either column "dbo" or the user-defined function or aggregate "dbo.CK_LoseTeamSportExists", or the name is ambiguous.
I've tested the function and it works in other contexts. Any idea? All code below:
Thanks,
- Bryon
create function dbo.CK_LoseTeamSportExists (@loseteam int, @sportid int)
returns bit
as
begin
declare @return bit
if exists
select TeamID, sportid from Link_TeamSport
where
TeamID = @loseteam
and
SportID = @sportid
set @return = 1
else set @return = 0
return @return
end
go
create table #check
SportID int
,WinTeamID int
,LoseTeamID int
,check
(dbo.CK_LoseTeamSportExists(LoseTeamID,SportID) = 1)

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data should
use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums.
>> I am trying to create a temp table that uses a UDF in a constraint. <<
You do not understand how SQL or any declarative language works!
We do not use UDFs (procedural programming)
We do not use bit flags (assembly language).
We do not use temp tables (mag tape files).
We do not use integer as identifiers (what math do you do on them?)
Your silly “Link_TeamSport” implies a pointer chain; we have no links in SQL. Where is the DDL?
Constraints are always predicates in any declarative language.
Do you know why you have to create a local variable to pass the non-relational flag back to the calling environment? FORTRAN I and II! These early languages has to use hardware registers in the first IBM computers to return results. In your ignorance, you mimic
them!
We do not use if-then-else control flow in any declarative language. We have CASE expressions that we put where you have a local variable getting an assignment.
I see you also put the comma at the start of the line. We did that with punch cards, so we could re-use them 50 years ago.
In SQL, we would use REFERENCES to assure a team reference exists. We use names for teams because they are entities, not quantities:
CREATE TABLE Game_Results
(sport_name CHAR(10) NOT NULL PRIMARY KEY,
win_team_name CHAR(12) NOT NULL
REFERENCES Teams(team_name)
ON DELETE CASCADE,
lose_team_name CHAR(12) NOT NULL
REFERENCES Teams(team_name)
ON DELETE CASCADE,
CHECK (win_team_name <> lose_team_name));

ORA-04044: procedure, function, package, or type is not allowed hereUsing PL/SQL code like that raises 2 basic problems. If that PL/SQL code for the calculating the column default breaks, what happens to the SQL insert statements against that table. These will need to fail as the table definition depends on the PL/SQL code. This is problematic as this dependency simply increases the complexity of the SQL object.
The 2nd issue is performance. PL/SQL code needs to be executed by the PL/SQL engine. This means a context switch from the SQL engine to the PL/SQL engine in order to determine the default value for that column. Context switching is a performance overhead.
So even if it was possible to use a PL/SQL function as parameter for the SQL default clause, I would not be that keen to use it.

Help in Mapping: User defined function

Hi All, I need your help in doing the following mapping:
The source contains the below fields:
Source_MT -- Under this          1...1
   LineItem                                 1...Unbounded
     CompanyCode          1..1
     Amount               1..1
   SubTotal                               1...Unbounded
     CompanyCode          1...1
     Amount               1...1
And the Target strunture should be:
Target_MT -- Under this
   Target                               1...unbounded
     CompanyCode          1...1
     AmountMatched          1...1
There will be multiple line items in the source for each compony code which I need to loop through and add the amounts. For a company code, The sum of the amounts in the line items should match with the amount in the Subtotal/Amount.
For each company code, a target should be created with the result whther the amounts were matched or not.
Below is the data example:
Source:
Line Item :
     CompanyCode          Amount
     ABC               5
     ABC               5
     XYZ               10
     ABC               7
     XYZ               6
Sub Total :
     CompanyCode          Amount
     ABC               17
     XYZ               5
Target should be:
CompanyCOde          Amount
ABC               Matched
XYZ               Not Matched
Hope I am clear with my requirement. Please let me know if you need more clarity.
I was able to create mapping, if the line items contains single company code. Need help with multiple company codes.
Any help would be appreciated.

I am still working on the same map (please refer above) for which you gave th3e solution. The solution almost worked.
I need to validate the line items with the subtotals. If the validation fails, I should throw an custom exception. If the validation is successful, then do nothing (do not create the target element).
Hope I am clear. Please let me know if I am not clear.
LineItem1: 10
LineItem2: 20
SubTotal1: 30
LineItem3: 5
LineItem4: 5
SubTotal2: 15
In the above example, eventhough LineItem1 and LineItem2 sum up to Subtotal1, LineItem3 and LineItem4 doesn't sum up to SubTotal2. So it should throw an exception because second validation failed.
Also, it should not create target element because first validation was successful.
I used the logic int he below link :
[http://www.flickr.com/photo_zoom.gne?id=2229287904&size=o]
In the "else" part of "If else" statement, I have a user defined function which throws exception.
If the output is "true", I am avoiding creating the target element using "Createif" statement.
But strangely, when the vaildation of first set fails (LineItem1, LineItem2 and Subtotal1), then it is throwing the exception.
But when the validation of second set fails, then it is not throwing the exception.
My current map looks like below:

Message Mapping (user-defined function)

Hi all,
Is there anyway to determine the XML message ID using an user-defined function in Message Mapping? When I go to SXI_MONITOR I see that all messages have an unique ID, but I'm having some difficulties to understand if there is any way to get that ID in a message mapping and pass it to a target structure? I see that it is possible to use constants like "Sender" and "Receiver", but I haven't found anything for the message ID.
Can you please help me?
Thanks in advance.
Regards,
Ricardo Inácio

Try this code..
Create an UDF and do not pass any arguments to it..
java.util.Map map;
// get runtime constant map
map = container.getTransformationParameters();
// get value of header field by using variable key
String msgid = (String) map.get(StreamTransformationConstants.MESSAGE_ID);
return msgid;
Now map this udf to your target field. Now test it....
P.s. Since message id is run time property therefore in mapping test tab it will not work. Try it at runtime.

Sarvesh

Need user define function for the message mapping structure

Hi All
I am new to XI.I need the java code for Udf for the following structure.
i have two input and one out put as error.

order_details----
num of orders---- i.e. 10
order_details------ i.e. whole order records details
1.i have to compare the 1st input with 2nd one means if the ist input contain 10 means there are 10 orders in 2nd input.if not then i have to give error message .
2.then i have to check the fields in 2nd input has no null values.if no values the output will be error message.

In Ref cursor, user defined functions give "invalid column" error in EJB.

Hello,
I have written PL/SQL stored procedures/functions in Oracle 8i. They return the result set as a ref cursor.
These procedures are accessed by EJB (weblogic) using Type 4 (100% Java) JDBC Driver.
My problem is - if I use a user defined function to fetch a value in the select statement of the reference cursor, the EJB gives an error msg - invalid column name.
If instead of using the function I get the value directly from the table, it works fine. Refer the code below :
//In the PL/SQL function -
//instead of writing :
Open rc for
Select empcode, empname
from emp ;
//If I write :
Open rc for
Select empcode, mypack.getempname(empcode)
from emp ;
//getempname(empcode) is a function in
//in a package named 'mypack'
//and returns name for empcode.
//The java code gives error
//error : invalid column name
//While both are working fine and
//returning currect result in SQL Navigator.
Help me solve this mystery ?
Thanks in advance.

Hi:
When use inline Function to simplify the SQL statements, there is one thing that one should conside--Purity Level.
if you create standalone stored pl/sql function. Oracle implicitly determines the PURITY level during compilation of the stored objects or at execution of an anonymous pl/sql block.
if you implement Package inline Function( in your case),unlike standalone stored pl/sql functions, the PL?SQL Engine does not determine the purity level of package functions. Therefore, you must explicity assign the correct purity levels for the function to be called inline.
the code like:
create or replace package mypack is
function getempname(empcode emp%empid%type)
return varchar2;
PRAGMA RESTRICT_REFERENCES(getempname,WNDS,WNPS,RNPS);
end mypack;
I think it can solve your problem if you use enough "pure"to be called inline function. Or you can create the standalone function to do it.
good luck!

10g - cache, report contains oracle user defined function

hi, experts,
from http://obiee101.blogspot.com/2008/07/obiee-cache-management.html
Reasons Why a Query is Not Added to the Cache:
•Non-cacheable SQL element. If a SQL request contains Current_Timestamp, Current_Time, Rand, Populate, or a parameter marker then it is not added to the cache.
•Non-cacheable table. Physical tables in the Oracle BI Server repository can be marked 'noncacheable'. If a query references any non-cacheable table then the query results will not be added to the cache.
•Cache hit. In general, if the query gets a cache hit on a previously cached query, then the results of the current query are not added to the cache. The exception is query hits that are aggregate roll-up hits.
•Result set is too big.
Query is cancelled. This can happen by explicit cancellation from Oracle BI Presentation Services or the Administration Tool, or implicitly through timeout.
•Oracle BI Server is clustered. Queries that fall into the ‘cache seeding’ family are propagated throughout the cluster. Other queries continue to be stored locally. Therefore, even though a query may be put into the cache on Oracle BI Server node 1, it may not be on Oracle BI Server node 2.
I would like to know
if the request (report on dashboard) calls an oracle user defined function, can the cache be created and saved for this report?
thank you very much!

Hi stephen,
if the request (report on dashboard) calls an oracle user defined function, can the cache be created and saved for this report?Yes,it is cached.....function defined in database is called in OBIEE is cached and saved.
More information and example can be found here http://oraclebizint.wordpress.com/2007/09/10/oracle-bi-ee-10133-support-for-native-database-functions-and-aggregates/

SQL User Defined Functions for performing statistical calculations

Hi!
   I hope you can help. I just wasn’t sure where to go with this question, so I’m hoping you can at least point me in the right direction.
   I’m writing a SQL Server stored procedure that returns information for a facility-wide scorecard-type report. The row and columns are going to be displayed in a SQL Server Reporting Services report.
   Each row of information contains “Current Month” and “Previous Month” numbers and a variance column. Some rows may compare percentages, others whole numbers, others ratios, depending on the metric they’re measuring. For each row/metric the company has specified whether they want to see a t-test or a chi-squared statistical test to determine whether or not there was a statistically significant difference between the current month and the previous month.
   My question is this: Do you know where I can find a set of already-written user defined functions to perform statistical calculations beyond the basic ones provided in SQL Server 2005? I’m not using Analysis Services, so what I’m looking for are real SQL User Defined Functions where I can just pass my data to the function and have it return the result within a stored procedure.
   I’m aware that there may be some third-party statistical packages out there we could purchase, but that’s not what I’m looking for. And I’m not able to do anything like call Excel’s analysis pack functions from within my stored procedure. I’ve asked. They won’t let me do that.   I just need to perform the calculation within the stored procedure and return the result.
   Any suggestions? Is there a site where people are posting their SQL Server UDF’s to perform statistical functions? Or are you perhaps aware of something like a free add-in for SQL that will add statistical functions to those available in SQL? I just don’t want to have to write my own t-test function or my own chi-squared function if someone has already done it.
Thanks for your help in advance! Oh, and please let me know if this should have been posted in the TSQL forum instead.  I wasn't entirely sure.

How to check empty idoc fields in user defined function

Dear All,
I am working on an IDOC to file scenario. In my user defined function, I want to check whether a particular field of the idoc is populated. I can perform this test in message mapping by comparing the field with an empty constant.
How can I do the same test in an advanced user defined function? I have tried all the following, but none has worked so far
If (a.length == 0) .
If (a[0].length == 0)
If (a[0] == )
If (a[0] == )
Am I doing something wrong?
Thx/Farshad

To check whether an element is not available:
if (a.length == 0)
but you have to set cache to context. If you set cache to queue, it will not work, as in this case the context changes are part of the array a.
To check whether an element is empty:
if (a[0].equals(""))

Stefan

Hi Eric,
I have a Proxy service it reads mfl data and transform to some other schema.In this Transformation one element data is taken and we have to manipulate that data
based on the incoming value and return .For this process i took one function and i have to check weather it contains some symbols like ^,~ so i used contains function of
String with and with out prefix with if else condition it gives error "Unexpected token if"
declare function insp:buildReferenceRange($inRange as xs:string)
as xs:string
let $low:=""

Accessing a Cache From an Oracle CQL User-Defined Function

According to the docs ...
I am to use the following element to set the cache property in my bean...
<wlevs:property name="cache" ref="cache-id"/>
However, when I set it, the assembly does not validate.
If I use <property>, I get a NullPointerException on each request when my processor runs.
Using the same CQL code..
Without the <property> tag, the call to the user-defined function works (but I don't have the cache attribute set obviously).
Here is the excerpt from my assembly...
<bean id="cacheFunction" class="ou.cep.function.CacheFunction">
<property name="cache" ref="myCache"/>
</bean>

<wlevs:processor id="myProcessor">
<wlevs:listener ref="CacheChannel"/>
<wlevs:function ref="cacheFunction" function-name="isValidID" exec-method="isValidID">
</wlevs:function>
</wlevs:processor>
To repeat, with the same CQL with the user-defined function call, if I remove the property element from the bean definition, I can call the function successfully (it just doesn't do what I need it to do). In this case, I am still using the ref=cacheFunction for the wlevs:function within the processor.
What am I doing wrong?
Edited by: fl0at on Oct 5, 2010 12:22 PM
Edited by: fl0at on Oct 5, 2010 12:28 PM

The case is solved, not sure I could explain why, but...
This implementation of the user-defined function was a migration from an implementation using the same cache in the join. So, when I removed the cache reference in the source stream (where I am now executing a function that accesses the cache), the problem went away and everything is working.
I can explain further if there are questions.
If anyone has thoughts on this, please advise.
As always, thanks for the help.
