Help: How to call a user defined function in a data block query?

I created a string aggregation function in the program unit, see reference:
http://www.oracle-base.com/articles/10g/StringAggregationTechniques.php
I now like to call the function in my data block query. I got the error: ORA-00904: 'concatenate_list' invalid identifier.
Please help.
Thank you in advance.

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.

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.

Urgent Help Needed - Associating Statistics with User-Defined Functions

Hello,
We have an appication uses cost-based optimizer and uses a lot of TO_DATE and SYSDATE calls in FROM and WHERE clauses. For certain reasons, every call to TO_DATE and SYSDATE has been replaced by MY_TO_DATE and MY_SYSDATE respectively (which in turn call built-in functions). However, cost based optimizer is behaving strangely, which is understanble, based on the lack of user-defined functions statistics. I am under the impression that I should use something like:
ASSOCIATE STATISTICS WITH FUNCTIONS my_to_date DEFAULT SELECTIVITY ?;
ASSOCIATE STATISTICS WITH FUNCTIONS my_to_date COST (?,?,?);
ASSOCIATE STATISTICS WITH FUNCTIONS my_sysdate DEFAULT SELECTIVITY ?;
ASSOCIATE STATISTICS WITH FUNCTIONS my_sysdate COST (?,?,?);
but what should the values (?) be?. I guess I want to replicate TO_DATE and SYSDATE values, but how would I find out what they are? Thanks in advance...
P.S. I am also looking for workarounds (I cannot create a synonym for TO_DATE right?), so any help is welcome!!!

Hi emmalou69 ,
You told your actual parameter is
5, 5, 7.3 and 'z'
so change your method like
public static int test(int x, int y, double d, char ch)
because 5 - int; 7.3- float or double; z is char.
your method returns
public static int.
so you should return only int variable. but in your code you mentioned double. it's not correct.
The original code should look like
public class rubbish
     public static void main(String args[]){
          rubbish f = new rubbish();
          f.test(5, 5, 7.3 ,'z');
     public static int test(int x, int y, double d, char ch)
          int value;
          x = 5;
          y = 5;
          d= 7.3;
          ch = 'z';
          value =((int) d + x + y + ch);
          System.out.println( x + ch + d + y);
          return value;
}//here int value of z is 122.
and int(7.3) is 7
so 7+5+5+122 = 139.3
but value =((int) d + x + y + ch); returns 139. because you convert double to int that is 7.3 to 7
If it is useful, rate me duke dollars,
Thanks

Can you provide your function code? Using a function like that is possible from the below example. I suspect something in your function code.

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 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)

Calling a User defined function from Data Model in BIP

I am new to Procedures and Functions and am not sure if I am doing it right, so please bear with me.
My User Function:
create function MyTempFunction(@master_key varchar(max))
returns VARCHAR(MAX)
begin
DECLARE @Names VARCHAR(8000)
SELECT @Names = COALESCE(@Names + ', ', '') + vndt.name
from
[CMPROJ].[dbo].[VNDT] as vndt,
[CMPROJ].[dbo].[CRQT_QUESTION_DISTRIBUTION] as CQD
where CQD.parent_key=@master_key
and CQD.project_name=vndt.project_name
and vndt.initials=CQD.distributed_to_ini
return @Names
endIf I call the function in my query window I get a result:
"Ron Swanson, Anne Perkins"
But if I put the same query into my Data Model in BI Publisher and try getting the XML Output, my data is blank.
This is how I call the function:
select top 1 dbo.MyTempFunction('98d4dfa893164d138d5f961fa4') as Names from dbo.[CRQT_QUESTION_DISTRIBUTION]And I know that BIP did access the function, because the first time I tried to save the new SQL Query, it threw an error saying it was denied access to the function and I had to add the user to be able to execute the function.
I am new to doing Procedures and Functions, so I am not sure if I am even doing it right.
And don't know if even calling procedures or functions works form BIP.
Any help appreciated.
Thanks

Thanks for the suggestion, but I still get nothing in the XML result set.

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.
Regards,
Ricky

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?

Can COLMAP call a User Defined Function?

Hi, I'm new to GoldenGate. We are replicating many source databases into a single target database. All source databases have the same schema but with different data. I need to generate a GUID to insert into a new column in every table in the source database. Can I do this with COLMAP? If so, how can I generate a GUID with COLMAP?
If this is not possible, what would be a good solution? Should we use BEFORE INSERT triggers in the source DB to insert the GUID? The guid column is only on the target DB and not in the source DB.
Thanks.

Create a procedure to get the data you want:
CREATE OR REPLACE PROCEDURE LOOKUP
(CODE_PARAM IN VARCHAR2, DESC_PARAM OUT VARCHAR2)
BEGIN
SELECT DESC_COL INTO DESC_PARAM
FROM LOOKUP_TABLE
WHERE CODE_COL = CODE_PARAM;
END;Then, in your replicat, use SQLEXEC:
MAP HR.ACCOUNT, TARGET HR.NEWACCT,
SQLEXEC (spname lookup,
params (code_param = account_code)),
COLMAP (USEDEFAULTS, newacct_id = account_id,
newacct_val = @GETVAL(lookup.desc_param));The @GETVAL function maps values returned in desc_param to the newacct_val column.
