USER DEFINED FUNCTIONS IN FORM 6i

I am interested to learn how can I manipulate, call a database user define function in a form6i that I am now using. It should give me desire database information on the forms? I am sorry, if I could explain the topics?
Thanks & regards
Dharani Barman

Just call the function from PL/SQl or SQL in your Forms code - it shoudl all work providing that the user you are connected as has access to and execution rights on that function, and that the function uses parameters and return types that are compatible with the version of PL/SQL that the Forms engine has.

Error while using user defined function in reports

Hi,
When I use the below user defined function in oracle reports I got the wrong number of arguments error
select test_function(id,a_number,v_date-14,b_number) from dual;
If I remove -14 from the argument it works. But iIneed to subtract 14 days from the date.
Thanks for your help.

select test_function(id,a_number,v_date-14,b_number) from dual;
you have to give the command like this to_date(v_date,'dd-mon-yyyy')-14
because the v_Date you choose in the parameter form is not having the corrent date format
the format dd-mon-yyyy is the format in which v_date is passed by the user.

Error in conditional map using User Defined Function

All,
In my mapping I basically have a user defined function that returns the filename of my inbound file from the adapter-specific message attributes (file adapter). I know this is coded properly because if I simply assign this function to my destination field I can see the filename in the payload XML.
However if I conditionally check that returned value using if,then,else I get an error message stating:
"During the application mapping com/sap/xi/tf/_MaterialData2ZcustProdMastMulti_ a com.sap.aii.utilxi.misc.api.BaseRuntimeException was thrown: RuntimeException in Message-Mapping transformation"
Essentially in my if I'm checking if the value returned by my user defined function is equal to the constant "SOMECONSTANT" then I'm setting my destination field to some other constant value. Otherwise it's equal to a different constant value.
Any thoughts?

Claus,
Thanks for the help. I actually had figured the problem out on my own. Sorry for not updating the thread sooner. What happened was this (as I suspected it wasn't related to my user defined function). For the newbies out there (of which I'm one) the problem was I was comparing strings in the graphical mapping tool using the Boolean "EQUALS" rather than the Text "EQUALSS".
Can you give yourself points for solving

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?
Regards,
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 (Part 2)

Hi,
István Korös has finally solved my problem on User Defined Function.
See
My objective was to write a simple UDF to represent the following formula which Gordon Du gave me:
(DATEADD (s, -1,
DATEADD (mm, (DATEDIFF (m,0,@refdtzz ) + @mthnumber), 0)))
However, the solution proposed by István, although it works perfectly, leaves me scratching my head. Let's see why?
The only difference between my solution and that proposed by István is that István enclosed the UDF name between .
I wonder how this can make the vital difference between a (simple query!) that works well and one that gets blocked.
I tried several combinations of and am in for a few surprises, listed below. Can anybody explain what's going on?
Solution proposed by István:
CREATE FUNCTION [dbo].[udf_EndOfMonth]
and executed as:
select [dbo].udf_EndOfMonth (@refdt1 , 1)
Remarks: works perfectly
If I execute the UDF with exaclly the same name as in CREATE, it does not work
CREATE FUNCTION [dbo].[udf_EndOfMonth]
and executed as:
select [dbo].[udf_EndOfMonth] (@refdt1 , 1)
Error Msg: Must specify table to select from
If I don't put the , the function is created, but the execution of the calling query returns error
CREATE FUNCTION dbo.udf_EndOfMonth
Remarks : Creation OK
and executed as:
select dbo.udf_EndOfMonth (@refdt1 , 1)
Error Msg: Must specify table to select from
It seems that the only combination that works is that provided by István.
This is surely a simple UDF.
I don't know what to do if I attack a more complicated UDF.
Grateful if anybody could help light my way.
Thanks
Leon Lai

Hi Leon,
As István has already pointed out, there is no documentation for those small differences to make the SQL work or not. He must be tested quite a few times to find the actual working code. This question can only be answered by the developer who made this part for B1.
Thanks,
Gordon

User-Defined Function and Context Manipulation

Hi Mapping Gurus, I need your help.
I have a user-defined function and one of my input parameter (c) is in a loop (EDI segment). So one, if I execute my function I get:
Exception:[java.lang.ArrayIndexOutOfBoundsException: 0]
If I change the context or use the remove context node function its working but its always taking the first row in consideration since I'm using c[0] . Here is the logic:
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[0]"'";
So since c is an array [], I have tried different logic to get to the right row.
1- I tried using another parameter (e) to pass a counter or an index to my function. So each time it's looping, it's passing a new value to the function but Im still getting the first row and Im not to sure why?
int G = Integer.parseInt(e[0]); // e[] = My counter field
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
2- I tried using a parameter stored in the container:
String Num;
Num = (String)getParameter(counter);
if (Num == null) G = 0;
else
G = Integer.parseInt(Num);
G = G + 1;
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
Num = "" + G;
setParameter(e[0], Num);
and Im still getting the first one, look like its using a different container each time its looping so the Value is always the same?
4- I created a new user-defined function with the container logic, then its working but Im back to the same problem in my main function, its only looking at e[0] for my counter all the time.
5- I tried using the Seeburger Java Variables and guess what in the main fonction, as new UDF,... and guess what, same result!
So anybody out there that was able to get UDF's working into a multiple context scenario?
Am I missing something?
I will reward points and beer for any help!

This is one of the text with passing a counter to the function to try to go to the right row in the array since I'm doing a remove context and I'm getting all the d_234's:
public void ReadTable(String[] a,String[] b,String[] c,String[] d,String[] e,ResultList result,Container container){
int G = Integer.parseInt(e[0]); // My counter
String var;
String DBTABLE = a[0];
String lookUpField = d[0];
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
Now this one was with the internal container logic:
int G;
String DBTABLE = a[0];
String lookUpField = d[0];
String Num;
Num = (String)getParameter(e[0]);
if (Num == null) G = 0;
else
G = Integer.parseInt(Num);
G = G + 1;
Num = "" + G;
setParameter(e[0], Num);
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
And now with the Seeburger Variables:
int G;
try {
VariableBean be=VariableFactory.getVariableInstance("");
G = Integer.parseInt(String.valueOf(be.getStringVariable("yves")));
} catch (Exception f) {
throw new RuntimeException(f);
String DBTABLE = a[0];
String lookUpField = d[0];
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
try {
G = G + 1;
Num = "" + G;
VariableBean be=VariableFactory.getVariableInstance("");
be.setStringVariable("yves",Num);
catch (Exception f) {
throw new RuntimeException(f);
All 3 logics were returning always the first row or a counter of 1 if the logic is in the main ReadTable function.

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?
/people/saravanakumar.kuppusamy2/blog/2005/12/15/socket-integration-with-xi
Regards

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.

User defined function during Mapping.

Hi,
I am trying to retrieve filename using user defined function.
The payload is simple.
<?xml version="1.0" encoding="UTF-8"?>
<ns0:FTPTOFTP_MT_OB xmlns:ns0="urn://ftptoftp.com">
   <RECORD>
      <ROW>
         <EMPNO>723</EMPNO>
         <NAME>Jack</NAME>
      </ROW>
   </RECORD>
</ns0:FTPTOFTP_MT_OB>
the code for user defined function is
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
return ourSourceFileName;
now during message mapping ...
do I have to have extra xml tag in the destination
message which is now having
<?xml version="1.0" encoding="UTF-8"?>
<ns0:FTPTOFTP_MT_IB xmlns:ns0="urn://ftptoftp.com">
   <RECORD>
      <ROW>
         <EMPNO>723</EMPNO>
         <NAME>Jack</NAME>
      </ROW>
   </RECORD>
</ns0:FTPTOFTP_MT_IB>.
If yes ...
Then how to graphically map this extra xml tag.

Hi Deepak,
If u want to display the source file name in ur output, then ur output XML structure there should be an extra tag for displaying the file name.
In message mapping, select the user defined function which u have already created and map it to the tag for storing the file name in the target message XML format.
There is a editor present to write the user defined function on the bottom left corner of the message mapping screen.
For this function u need to select the Simple Function Tab.
Regards
Neetu

User Defined Function is not recognizing java class in IR.

Hi All,
i have written one normal java class, and i imported that java class into IR using imported Archive as a .jar file,
it will add just two values .
now in message mapping i created one user defined function in that
iam trying to call this java class. while testing it is showing error as cannot resolve symbol java class name
so experts please help me in this or it would be appreciate if any one will provide
step by step process of one java class and one USD just to add two numbers.
thanks in advance,
jasmine .

Hi,
The steps are as follows:
1) Create a java file with .java extension.
2)Compile it to create a .class file.
3) Create a zip file for this .class file using any compressed archive program(ex-winrar)
4) Upload this zip file as an imported archive ,save and activate.
When you go to this archive,below , you can see your .class file with the older path,for below ex:
ObjRecord.class jxl/biff/drawing/
you have to give following entry in imports section:
jxl.biff.drawing.ObjRecord;
Please try this and let us know if this works.
Thanks.

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.

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));

User Defined Function Missing In EF 6?

I'm using Entity Framework 6 and I have imported several user-defined functions like the one shown below, but it doesn't
appear when I try to select the function in intellisense and the model doesn't recognize this function as a method on the EF context. How do I call this function in EF 6?
<Function Name="getCycleDate" Aggregate="false" BuiltIn="false" NiladicFunction="false" IsComposable="true" ParameterTypeSemantics="AllowImplicitConversion" Schema="dbo" ReturnType="date" />

Hello DallasSteve,
>> I have imported several user-defined functions like the one shown below,
What is your UDF? If it is a TVF, starting from EF5, it is supported already:
https://msdn.microsoft.com/en-us/data/hh859577.aspx
However, it is a scalar function, unfortunately, as far as I know, even entity framework 6 doesn't suport generating calls for scalar functions by default. The workaround is to write a custom method like this inside your DbContext class, for example, there
is scalar function as:
CREATE FUNCTION [dbo].[Function20150410]
@param1 int,
@param2 int
RETURNS INT
AS
BEGIN
RETURN @param1 + @param2
END
When we imported it to the model, it would generate code in SSDL as:
<Function Name="Function20150410" Aggregate="false" BuiltIn="false" NiladicFunction="false" IsComposable="true" ParameterTypeSemantics="AllowImplicitConversion" Schema="dbo" ReturnType="int">
<Parameter Name="param1" Type="int" Mode="In" />
<Parameter Name="param2" Type="int" Mode="In" />
</Function>
While, it will not generate a call method as a store produce, for a workaround, we could write a custom function as:
[DbFunction("DFDBModel.Store", "Function20150410")]
public ObjectResult<int> GetContentByIdAndCul(int id, int culture)
var objectContext = ((IObjectContextAdapter)this).ObjectContext;
var parameters = new List<ObjectParameter>();
parameters.Add(new ObjectParameter("Id", id));
parameters.Add(new ObjectParameter("Culture", culture));
return objectContext.CreateQuery<int>("DFDBModel.Store.Function20150410(@Id, @Culture)", parameters.ToArray()).Execute(MergeOption.NoTracking);
I suggest that you write this custom method a separate cs file since if we update the model, the original context call would be reset.
Calling it as:
using (DFDBEntities db=new DFDBEntities())
var result = db.GetContentByIdAndCul(1, 1).FirstOrDefault();
}s
