How to use StreamTransformationException in user-defined function?

Hi,
I'm doing a DBLookup (using Java pgm in one of my Imported Java archives) for populating one of the fields in message mapping. If the DB connection fails, I want to terminate the mapping by throwing a StreamTransformationException from within a user-defined function.
I require urgent help in this regard.
Thanks in advance.

Sridhar Rajan N

Hi,
I had the same problem. I failed to find the way how to throw a StreamTransformationException in my user-defined function. But I used another exception: NullPointerException. Yes, I know, this is not an elegant solution...
Best regards,

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.)

HOW TO CREATE A GLOBAL USER DEFINED FUNCTION

Hi Expert,
I'd like to know if there is a way to globalize a user defined function?
I'd like to reuse a user defined function (e. g. DeleteLeadingCharacter) in several scenario/SWC instead of recreated it from scratch everytime - Is it possible?
Thanks

NO you cannot not reuse one UDF not even in other namespace even in the same namespace in diff Mapping programme.
UDF is liminted to GraphicalMappingProgramme that you created you cannot reuse it in other MappingProgrammes.
Like your MM =A has function <b>getMyName</b>
you can use it in MM=A but if you want to use it in MM=B then u cannot.
So its not possible in XI or PI.
But it is possible in new release PI 7.1. That says you can write UDF and can reuse in any MM programme.
Thanks

How to use negation in user defined rules?

Hi,
Can you please show me an example to use negation in user defined rule? I created a rule like below (the rule says if a patient has a fever problem and not have penicillin hypersensitivity, then recommend medication1):
INSERT INTO mdsys.semr_myMedicineRB VALUES('rule1',
'(?p rdf:type :Patient) (?p :present ?c1) (?c1 rdf:type :Fever) (?c2 rdf:type :Penicillin_Hypersensitivity)',
'(NOT_EXISTS(p :present c2))',
'(?p :recommendation :medication1)',
SEM_ALIASES(SEM_ALIAS('','http://www.example/medicine#')));
The rule successfully inserted into the rulebase. However, I cannot pass the entailment creation phase and got the errors:
ORA-29532: Java call terminated by uncaught Java exception: java.sql.SQLException: Missing IN or OUT parameter at index:: 1
ORA-06512: at "MDSYS.SDO_SEM_INF_INTERNAL", line 16453
ORA-06512: at "MDSYS.SDO_SEM_INFERENCE", line 302
ORA-06512: at "MDSYS.SDO_SEM_INFERENCE", line 352
ORA-06512: at "MDSYS.RDF_APIS", line 118
ORA-06512: at line 2
29532. 00000 - "Java call terminated by uncaught Java exception: %s"
*Cause:    A Java exception or error was signaled and could not be
           resolved by the Java code.
*Action:   Modify Java code, if this behavior is not intended.
According to the post built-in primitives(noValue,remove) for user defined rules, it seems negation is not supported in user defined rules. Can you please advice how to implement negation in user defined rules? Thanks a lot in advance.
Hong

Hi Hong,
Let's look at this similar but simplified problem:
if (?p rdf:type :Patient) and (NOT_EXISTS(?p :present :c2)) ==> (?p :recommendation :medication1)
You can use something like this in the user defined inferencing:
-- First get the numeric IDs for the relevant URIs
recomID := sdo_sem_inference.oracle_orardf_add_res('http://..../recommendation');
medID := sdo_sem_inference.oracle_orardf_add_res('http://..../medication1')
rdfTypeID := sdo_sem_inference.oracle_orardf_res2vid('... full URI for rdf:type');
patientID := ...
presentID := ...
c2ID := ...
-- Now this query will find out ?p that satisfy (?p rdf:type :Patient) but not
-- (?p :present :c2)
sqlStmt := '
select ids1.sid sub
     from ' || src_tab_view || ' ids1
    where ids1.pid= ' || to_char(rdfTypeID,'TM9') || '
      and not exists (
         select 1
           from ' || src_tab_view || '
          where sid = ids1.sid
            and pid = ' || to_char(presentID, 'TM9') || '
            and oid = '|| to_char(c2ID,'TM9') || '
insertStmt := '
insert /*+ parallel append */
   into ' || output_tab || '(sid, pid, oid)
select sub, '||to_char(recomID,'TM9') || ',' || to_char(medID,'TM9') || '
   from (' || sqlStmt || ')'

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 $low:=""
l
if(contains($inRange,"^")) //"Unexpected token if"
name space and prefix are defined in the top of file.

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.

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.

Calling user defined functions through OBIEE

Can anyone tell me how I can call the user defined functions on database through the new BI tool.
The idea is to collect certain parameters through the prompt when launching the request, the function is supposed to pick up the parameters, make a certain calculation, and return a value.
I wrote the function, I just need help over how to call the function through the BI tool - that was pretty easy in the old Discoverer.
Thanks.

Hi Kresimir ,
You can use EVALUATE function to call a user defined function.
EVALUATE('FUNCTIONNAME(%1,..)' As DATATYPE,parameter1,...)
Here DATATYPE is the returntype of function.
Hope this will help.
Thanks

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,
>use a simple user defined function with the desired

That function will only give me the actual lenght of the input element, what I need is the max lenght of the target element...
>You can also use the built-in FormatNumber function to

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

Advanced User Defined Function

Dear All,
I have a target structure as follows:
<Item>
   <Record10>
      <RecordType>
      <BankCode>
      <AccountID>
      <Amount>
   </Record10>
   <Record50>
      <RecordType>
      <Segment1>
      <segment2>
      <segment3>
   </Record50>
</Item>
I want to fill the elements in the Record50 in a special way by using some logic. Sometimes I may have to create multiple Record50 structures. So I'm using an advanced user defined function to do this.
My mapping is as follows:
Source Structure -> myFunction()->Record50
And in myFunction() I wrote the following piece of code:
result.addValue("50");
result.addValue("PayRef1");
result.addValue("Address");
result.addValue("Nil");
I expect the output to be:
   <Record50>
      <RecordType>50</RecordType>
      <Segment1>PayRef1</Segment1>
      <segment2>Address</segment2>
      <segment3>Nil</segment3>
   </Record50>
But the output is like this:
<Record50>50</<Record50>
<Record50>PayRef1</<Record50>
<Record50>Address</<Record50>
<Record50>Nil</<Record50>
Can somebody tell me how to proceed? I tried to insert a context change in the beginning, but then the Record50 itself is not appearing.
Thanks,
Sandeep

Hi,
Advanced UDF will not create you like you expected.
You need to do like this
Source>myFunction1()-><RecordType>
And in myFunction() you do code:
result.addValue("50");
Source>myFunction2()-><Segment1>
And in myFunction2() you do code:
result.addValue("PayRef1");
so on..
Thanks,
Prakash
