How to use a user defined function in XI

Hi Experts,
I would like learn how to use a user defined function in Xi during mapping . Is there any step by step on that.
Besides during when me make communcaton channels I see the following tabs...Paramters ..Identifiers ...Module...
The module that is given here ...where and how it is used.

Hi,
You can write UDFs in java in Graphical mapping to enhance your XI Graphical mapping functionality
The steps for doing it would be:
1. Click on Create New function Button found on Bottom left corner on your XI Mapping window.
2. Write your java code.
3. Run the Mapping Test as usual.
>>The module that is given here ...where and how it is used.
The adapters in the Adapter Framework convert XI messages to the protocols of connected external systems and the other way around. When doing so, some
functionality might need to be added specific to a situation which is possible with the use of custom modules.
Typical example would be validation of file content when using a File Adapter or modification of the message payload to a common content structure which is not supported by any of the standard SAP modules.
An Adapter module is developed as an Enterprise Java Bean and is called locally by the Adapter.
An example on modules :

How to use a user defined function in where cluase condition

Hi,
I have designed a query by selecting some columns in the tables and some columns are retrieved directly from table and some columns are passing to a user defined function. Now my requirement is i need to use that user defined function result in oracle where condition clause.
Ex : select marketing_user_id,get_name(marketing_user_id),item_id,get_item_name(item_id),get_country_name(country_id),
from
where get_item_name(item_id) in ('x','y','z')
and get_country_name(country_id) in ('India','America','China');
When am i trying the query by above format i am getting the wrong resultset.
BR,
uma

I am not sure why your getting the wrong results but you should seriously reconsider the approach your are taking. Using functions like this is very ineffecient and should be avoided at all cost.

How many types of user defined functions are there?

how many types of user defined functions are there?

Hi Ramakrishna,
A user-defined function is only visible in the message mapping in which you created it. You can insert the function in the data-flow editor as a standard function by using the User-Defined function category.
You can use the following user-defined functions:
1.Simple functions, which can process individual field input values for each function call. Simple functions therefore expect strings as input values and return a string.
2.Advanced functions, which can process several field input values for each function call. You can import either all field values of a context or the whole queue for the field in an array before calling the function. For more information, see Advanced User-Defined Functions.

     Advanced user-defined functions, which can process more than just individual field values.Instead, you can import a complete context or an entire queue for a field as an array before your function is called

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));

How to implement a user-defined function in a mathscript node

I am trying to use a mathscript node that includes self-defined functions, but I always get an error. I tried to run an NI-example: MathScript using Riemann Zeta.vi ,and I got the same error I get when I run my own programmes:MathScript Node'MathScript Node' (zeta): User-defined function contains an error. I didn't change anything in that example, so what could be wrong?

Try the Mathscript forum instead. Good luck.
(Maybe start reading this, for example)

How can I find user defined functions in oracle

Hello All,
I need to find out what are the user defined functions available in my schema?
Please let me know on what system tables shall I query and find out the user defined functions?
Thanks,
Milind.

Thanks Satish,
One more query. Can I find what are the parameters that needs to be passed?
Here is what I have to do..
I have to find all the accessible user defined functions. If I select one of them in my UI, I need to show the parameters used in the respective function.
Please let me know if these parameters are stored anywhere..
Thanks again,

How to distinguish the User-Defined-Function from Oracle Build-In function

Hi Friends,
I could get the function list form all_objects table by the SQL:
select * from all_objects where object_type = 'FUNCTION'
but there is no column in all_objects specify the function is build-in or user-defined.
But I found in SQL Server there is a column "is_ms_shipped" in the sys.all_objects table. This column will specify the object is build-in or user-defined. I want to get the equivalent column in Oracle but failed.
Could anyone tell me how to solve this problem?
Thanks,
Ricky

Thanks Pavan.
But if an user connects to database using "conn /as sysdba" syntax and creates a function. This user-defined funtion goes into the "SYS" schema also. I know it is not the best practise to create objects using sys user so I think your solution is right.

Ricky

Use of user defined function in mathscript containing structure

Hi, I am an beginner user of LabView's MathScript Module,
I have the following problem when integrating my MATLAB code into LabView, for HMM: In my program, I tried to call a user defined MATLAB function called 'mixgaussinit.m' It show this error ..
Error -90162 occurred at Line 36, Column 20: unexpected char: '.'
C:\HMMall\KPMstats\mixgauss_init.m
Possible reason(s):
LabVIEW: A recognition error occurred while generating a stream of tokens.
the line 36 of the file is this "mu = reshape(mix.centres', [d M])"
mix.centers is a structure..
How can this error be corrected?
Solved!
Go to Solution.

I just noticed that these files appear to be under copyright. My first question is do you have the copyright permissions to post them in a public forum? If not then you may wish to delete them. That being said I have examined the code and it seems easy enough to work around your issues (provided you have the copyright permissions). The way to work around the issues is indeed to replace the struct fields with variables. This will of course require you to change a couple function definitions to input and output the neccesary variables which I believe was at most 5 variables. You will also need to redo the error checking code that uses a cell array. Altogether I estimate about 30 minutes of work. I would have given you the work around in these files had the files not been copyrighted. So, unfortunately, you will have to implement the work around yourself.
Good luck!

How to develop a user defined function to convert XML to Base64Binary

Hello,
I am trying to develop a solution in which I need to convert XML into Base64Binary so that I can then write this Base64Binary opaquely to a file (as opaque data is nothing but Base64 encoded data)
So, I want to develop a flow in which:
*File Adapter (read file based on some XSD) ----{color:#99cc00}XML{color}-----> BPEL/ESB input ----{color:#99cc00}XML{color}--------->Transform ----{color:#99cc00}Base64Binary{color}---------File Adapter that writes files opaquely*
{color:#000000}
What should be the signature of such a function. How I can pass the input to it.
TIA
{color}

Think i got something here How to convert String to base64Binary in BPEL process
but its BPEL all the way, how to get hold of input in an ESB process?

How to Use Sequence Object Inside User-defined Function In SQL Server

I'm trying to call sequence object inside SQL Server user-defined function. I used
Next Value for dbo.mySequence to call the next value for my sequence created. But I'm getting an error like below.
"NEXT VALUE FOR function is not allowed in check constraints, default objects, computed columns, views, user-defined functions, user-defined aggregates, user-defined table types, sub-queries, common table expressions, or derived tables."
Is there any standard way to call sequence inside a function?
I would really appreciate your response.
Thanks!

The NEXT
VALUE FOR function cannot be used for User Defined function. It's one of the limitation.

Using a SQL user-defined function in Crystal Reports XI

Post Author: JoannKarp
CA Forum: Formula
Is it possible to use a user defined function in SQL and use this in multiple Crystal reports?
JoannKarp

SELECT COALESCE(ufn_GetAddressByBusinessEntityIDandAddressTypeID(table1.BusinessEntityID,712),ufn_GetAddressByBusinessEntityIDandAddressTypeID(table1.BusinessEntityID,712)) AS Zipcode
FROM table1
Nope. This is two function calls. coalesce(a, b, c, ...) is just syntatic sugar for
CASE WHEN a IS NOT NULL THEN a
WHEN b IS NOT NULL THEN b
WHEN c IS NOT NULL THEN c
END
But if you use isnull it's a different matter. (But isnull() permits two arguments.)
