Calling user defined stored FUNCTIONS in report

Post Author: fahimghauri
CA Forum: Data Connectivity and SQL
Hi,
I want to call database stored functions in report, but when I connect to database using DATABASE EXPERT it shows me tables,view and stored procedures not functions. How can I import/use functions defined in database into my report?
I am connected with DB2 v9.
Thanks in advance

other soluce:bring your function in a view and join this view on your request. (Work only for simple return) Sample:CREATE function fn_GetAge ( @i_Name char(10) ) returns SMALLINTBEGIN declare @o_Age smallint select @o_Age from Employ where Name = @i_Name return @o_Age ENDCREATE VIEW dbo.v_UserAgeasSELECT Table2.Username, ISNULL(dbo.fn_GetAge(Table2.Username),0) as Age FROM Table2 WITH (NOLOCK)GO

How can I call a stateful webservice from a user-defined XPath function?

I'm calling a stateful webservice from a BPEL process using a PartnerLink which implements Custom Header Handler classes to handle the session state, storing the cookie as a property of the PartnerLink.
I'd also like to call this same stateful webservice, in the same session, from a user-defined XPath function enabling me to call this from an XSL Transformation.
Is this in any way possible? Can I access the cookie and attach it to the webservice call made by the user-defined XPath function?

Actually, as long as the servlet returns valid javascript, you can indeed "call it" from the client. It will initiate a request and return the result to the browser.
This example uses Perl, but it could be easily modified to go to a servlet instead.
Note that it is only supported in DOM browsers (IE6+/NN6+/etc)

Need to call user defined table in Report

Hi there,
In my report, need to call user defined database table. This table contains 2 columns one for checkbox. After calling this table, user has to check required rows and save changes. can we create transaction code for this table and call from within report? anybody pls suggest how to implement this requirement.
Regards,
Zakir.

Zakir,
U can do it in both the ways (TXN or rept).
If rept, use an itab to check and insert rows to the DB tab.
If mod pol, use a table control and update db tab...

Matscript node void ouputs when calling user-defined functions

Hi,
I have a (for most of you, probably simple) problem with calling user defined function within a mathscript node.
I have a script inside a MathScript node which calls three UD functions. When I try to output variables, LabView sets their type to void, so I cannot use them further. this would imply, that the script is nondeterministic, (since the types would get set at runtime). However, if I replace the call to the UD function with the actual contents of the function, the variable becomes deterministic. Now, since I have several call to these functions, I have no desire in writing all of them many time, introducing many variables etc. What would you advise me to do?
Find attached my scripts and functions.
I need this script running on a RT Target, and have been battling this for weeks, with almost no success!
Thanks, Regards,
Luka

MArtin, hello!
As far as I know, LabView checks the syntax as you write in the MS Node, and since there is no X mark next to the line number, it indicates, that the syntax is correct. Since i have set the path to the UDF in both the VI options and in the general MAthScript setting, how does adding the path command help? even if I add path('directory') command, a yellow exclamation mark appears, saying the command is slowing down performance.
(this is the original help explanation:
The warning glyph indicates that LabVIEW operates with reduced error checking at edit time and slower run-time performance for the MathScript Node. The following conditions cause the warning glyph to appear. To remove the warning glyph from the MathScript Node and improve run-time performance, modify your script as follows to resolve the condition in your script:
Your script calls addpath or pathremove (legacy name rmpath), or calls cd, path, or userpath with one or more inputs, which change the MathScript search path list at run time. Remove these functions and use the MathScript page to configure the default search path)
Could you please post a screenshot of your VI, just to see, if you've got anything different set up?
I am running LV2012.

PL/SQL : User defined Aggregate Functions ??

Is it possible to create (using whatever language) a user defined aggregate function for transparent usage within sql ?
e.g.
select median(myField) from myTable
or
select empirical_expectation(myField) from myTable
thanx in advance ..
Tobias Oberstein

HI,
U can create a stored proc. (PL/SQL) for this and call as any other function.
By using external procedure, U can create shared library in C or C++ and coonect this shared library by using external function/procedure. This will be become user-defined procedure.
with regards,
Boby Jose Thekkanath.

User Defined External Function - How to work?

I have defined some external functions in java by following the description in
C:\OraBPELPM_3\integration\orabpel\samples\demos\XSLMapper\ExtensionFunctions
I can use my functions in JDeveloper, but they do not work on the Oracle BPEL engine.
Is it enough just to place the jar-file in <OC4J_HOME>\j2ee\home\applib and add the jar-file in class-path (as described)?
What about the xml-file specifying the functions (called SampleExtentionFunctions.xml in the documentation)?
Should this file be copied to <OC4J_HOME>\... ?
Here is the error message I get by running my service:
XPath expression failed to execute.
Error while processing xpath expression, the expression is "ora:processXSLT("TransformationInput.xsl", bpws:getVariableData("inputVariable", "request"))", the reason is java.lang.NoSuchMethodException: For extension function, could not find method org.apache.xpath.objects.XNodeSet.leadingZeros([ExpressionContext,] #NUMBER)..
Please verify the xpath query.
______________ MY JAVA CODE EXAMPLE: _____________________________
package extentionfunctions;
This is a sample XSL Mapper User Defined Extension Functions implementation class.
public class JavaExtensionFunctionsBpel
* Inserts leading zeros to a text, if this starts with a digit.
* Else the return value will be the same as the given text.
* The return value will have the specified length.
public static String leadingZeros(String text, int len)

char c = (text == ""?'0':text.charAt(0));
if ('0'<=c && c<='0'+9) { // Is first char a digit?

int n = len - (text == ""?0:text.length());
for (int i=0; i<n; i++) { // Insert zeros:

Flemming Als

Flemming, it looks like somthing is wrong in the xsl that it still goes to org.apache.xpath.objects.XNodeSet package instead of yours ..
I created a sample that illustrates the usage of this functions (even with 2 params, different types).
Java class (com.otn.samples.xslt.CustomXSLTFunctions)
package com.otn.samples.xslt;
public class CustomXSLTFunctions
<function name="extension:multiplyStringAndInt" as="number">
<param name="base" as="String"/>
<param name="multiplier" as="number"/>
</function>
public int multiplyStringAndInt (String pString, int pMultiplier)
int base = Integer.parseInt(pString);
return base * pMultiplier;
XML descriptor:
Note the types (in the java class and the xml descriptor)
for java:base -> string and for xslt:base -> string
for java:multiplier -> int and for xslt:multiplier -> number
<?xml version="1.0" encoding="UTF-8"?>
<extension-functions>
<functions extension:multiplyStringAndInt="http://www.oracle.com/XSL/Transform/java/com.otn.samples.xslt.CustomXSLTFunctions">
<function name="extension:multiplyStringAndInt" as="number">
<param name="base" as="string"/>
<param name="multiplier" as="number"/>
</function>
</functions>
</extension-functions>
Definition of variables in the process:
(as you can see, the base is a string - I do the conversion in my method, and the return value
is converted to a string by the engine)

<element name="CustomXSLTFunctionProcessRequest">
<complexType>
<sequence>
<element name="base" type="string"/>
<element name="multiplier" type="int"/>
</sequence>
</complexType>
</element>

<element name="CustomXSLTFunctionProcessResponse">
<complexType>
<sequence>
<element name="result" type="string"/>
</sequence>
</complexType>
</element>
Using the new function in the XSL transformation:
- watch out for the namespace declaration (xmlns:sample="...")
- and the usage (sample:multiplyStringAndInt)
<xsl:stylesheet version="1.0"
xmlns:ldap="http://schemas.oracle.com/xpath/extension/ldap"

Then I created a jar file with the class (and for testing the xml descriptor in it)...
and put it into j2ee/home/applib directory

Help! Can I have user defined extension function?

Under SQL Sever XML, I can write a xsl script like this:
<msxsl:script language="JScript" implements-prefix="myfunc">
function getvalue(nodelist,name,istag){
var subNode=nodelist.nextNode();
if(subNode == null) return('?');
if(istag == '') name = '@' + name;
var value=subNode.getElementsByTagName(name);
return((value == null)?'':value);
</msxsl:script>
and I can call this function in the xsl, obviously, msxsl supported by microsoft. I know that Oracle XML support Extension function, but you can tell here that I want a user defined function while not a predefined function. Can I have such feature with Oracle XML, and How? Thanks.

Oracle XML support Extension function.
For example:
If we would like to import FAQDBUri.class with user-defined java functions, like TranslateDBUri(), we can write XSL file like this:
<xsl:template match="/" xmlns:dburig="http://www.oracle.com/XSL/Transform/java/FAQDBuri">
<xsl:variable name="urladd" select="dburig:TranslateDBUri($url)"/>

USER DEFINED TABLES IN XL REPORTER

Hello,
I have a user defined field based on a user defined table with code and name. I call my user defined field in XL reporter. This field varied with the data that I report. I would like to know how I can add the name of the table in my XL report. We can call additionnal tables, but I don't know how I can write the instruction to do it with a variable field.
Thanks

Isabelle,
Usere Defined Tables are not supported by the XL Report Writer. There is not a method to import UTD's at this time. User Defined Fields (UDF's) are supported.

HowTo: Business User defining Planning Functions?

Hi all,
does anybody have experience with allowing Business users Defining Planning Functions (e.g. account A = account B - account C) and could share a rough concept? I basically think about Fox-Formulas, but this includes issues with authorization in productive system.
Are there any solutions with translating free-text-Formulas (e.g. defined in an Attribut or flatfile, see scenario below) into ABAP or FOX Code?
Thanks for sharing your ideas and experiences,
Best regards,
Michael
Our scenario:
- Business users are responsible (and authorized) for specific local Companies.
- Values of the Chart of accounts are typed in into a input-ready query.
- for Dummy accounts (e.g. Z01) of the local companies no planning is allowed in the plan version, but business users should be allowed to define a specific formula, such as:
= + *
- these functions run at the end of the planning process in a separate planning version for translating local data into global accounts
- At best these functions should be maintained as an attribut of the dummy accounts or as free text in a text field next to the account in the plan query, but how to translate the formula into a Fox or ABAP formula without great effort?
- When using FOX, the issue is, that it is a different GUI and there would have to be a function for each company (there will come new companies) and so on....

Hi Matthias,
thanks for the post. The problem isnt of keying in the formula isn't that big, this can for example be done in an attribute Char 60 with Flatfile upload for each planning process.
My problem is more
a) if I use FOX Formulas - the usage of fox formulas in productive system for Business User
I still think that using FOX formulas is the easiest thing to implement, but probably the hardest to run and maintain life. Are there any best practises / how tos about authorization and IP architecture for that?
b) if I use formulas as Text - the formula parsing itself and the communication with the planning function
Here you gave me the hint of using customer defined planning functions. That's probably the best thing. I first thought about about a formula parser that is called by fox. Still, parsing free text into structured formulas isn't easy, is it? Are there any how-tows?
best regards,
Michael

How can I use User-Defined Aggregate Functions in Timesten 11? such as ODCI

Hi
we are using Timesten 11 version and as per the documentation, it doesn't support User-Defined Aggregate Functions.
So we are looking for alternatives to do it. Could you please provide your expert voice on this.
Thanks a lot.
As the following:
create or replace type strcat_type as object (
cat_string varchar2(32767),
static function ODCIAggregateInitialize(cs_ctx In Out strcat_type) return number,
member function ODCIAggregateIterate(self In Out strcat_type,value in varchar2) return number,
member function ODCIAggregateMerge(self In Out strcat_type,ctx2 In Out strcat_type) return number,
member function ODCIAggregateTerminate(self In Out strcat_type,returnValue Out varchar2,flags in number) return
number
How can I use User-Defined Aggregate Functions in Timesten 11? such as ODCIAggregateInitialize ?

Dear user6258915,
You absolutely right, TimesTen doesnt support object types (http://docs.oracle.com/cd/E13085_01/doc/timesten.1121/e13076/plsqldiffs.htm) and User-Defined Aggregate Functions.
Is it crucial for your application? Could you rewrite this functionality by using standart SQL or PL/SQL?
Best regards,
Gennady

XSLT Mapping - user defined Extension function

Hi to all,
can somebody helps me, please?
I need an own function, that can be used by the XSL Mapper. First I have only tried the sample given in Path <BPELPM>\integration\orabpel\samples\demos\XSLMapper\ExtensionFunctions
There is a java file with the defined functions and a xml file with the definition of this function for the mapper and last but not least a jar-file with the java class.
I have copied the jar to <JDEV_HOME>\jdev\lib\ext directory and in JDeveloper I have added SampleExtensionFunctions.xml to Tools->Preferences->XSL Map -> "User Defined Extension Functions Config File" field. After a restart of JDeveloper I find 2 new functions in the "User Defined Extension Functions" component palette page when a XSL Map is open. That's fine.
But if I test the mapping I get an error: "Failed to transform source XML.
java.lang.NoSuchMethodException: For extension function, could not find method org.apache.xpath.objects.XNodeSet.replaceChar([ExpressionCotext,]#STRING, #STRING)."
What is wrong?
Thanks in advance of your answer
best regard,
uno

Please help for User defined extension functions

the tutorial given for extension functions doesn't work as well as our new functions
even though i follow all the given steps and see the functions in my user defined extension functions tab in xslt map.
all the target nodes that use the extension function disappear in the resulted target xml.
please help.

have you compiled your java file and uploaded the jar file(containg the .class file and the Manifest.MF file) in the <OC4J_HOME>\j2ee\home\applib directory and then restarted the server??
