Problem with user defined function in XQUERY

Hi,
I have a file in which I store XQUERY. My java program reads this file and executes the xquery
and output the result. I have a working XQUERY in a file, which is something like :
<feed>
let $entries := for $x in collection('/path/to/atomStore.bdbxml')/entry[matches(id,'
.entry')]
order by $x/updated descending
return <entry xmlns="http://www.w3.org/2005/Atom">{$x/id,$x/title,$x/published,$x/updated,$x/link}
</entry>
let $latest := fn:subsequence($entries, 1, 10)
for $f in $latest return $f
</feed>
After adding the following simple function(I'm not calling it anywhere for the time being),
I'm getting an error
com.sleepycat.dbxml.XmlException: Error: Error in XQuery expression:
Unrecognized character 'a' (0x61) [err:XPST0003], line 33, column 2, errcode = XPATH_PARSER_ERROR
declare function xml:convertdate($date as xs:integer) as xs:string
let $months := ("jan","feb","mar","apr","may","jun","jul","aug","sep","oct","nov","dec")
let $month := $months[$date]
return $month
I couldn't find any error with the function syntax. Anyone has any idea?

Anoop

Hi Anoop,
The query and function work fine for me. What does the line and column information in the error point to?

Problem with User-defined function

Does anyone know how to make the user-efined functionto return a object. We know how to run a java class within cal script and pass the result to that java class. However, what we need is to be able to return the result in the form of a java class within the calling class. This is because we are calling the calscript within ejb and the ejb that executes the calscript needs to be able to get the result back.In our case, we are using webLogic EJB to execute a EDS calScript function. We don't know how to have the object created by EDS to be passed back to the EJB.Any insight will be greatly appreciated.Thanks,Anne

Need help with user defined function

Hello SDN,
I need some help with a user-defined function. My source message contains multiple
generic records (1000 char string), and my target message is 1 header record,
then multiple generic records. See description of source and target messages below:
Source:
GenericRecordTable 1..unbounded
    Row (1000 char string)
Target:
Field1 (char5)
Field2 (char5)
Field3 (char5)
IT_Data
    GenericRecordTable 1..unbounded
      Row (1000 char string)
Basically, what I need to do in my user defined funtion is to map the first record
in my source record to the 3 header fields, then map all of the rest of the records
(starting from line 2) into the GenericRecordTable.
Can someone please help me with the code for the user defined function(s) for this
mapping?
Thank you.

hi,
Activities
1. To create a new user-defined function, in the data-flow editor, choose Create New Function (This
graphic is explained in the accompanying text), which is located on the lower left-hand side of the
screen. In the menu, choose Simple Function or Advanced Function.
2. In the window that appears, specify the attributes of the new function:
Name
Technical name of the function. The name is displayed in the function chooser and on the data-flow
object.
Description
Description of how the function is used.
Cache
Function type (see above)
Argument Count
In this table, you specify the number of input values the function can process, and name them. All
functions are of type String.
3. In the window that appears, you can create Java source code:
a. You can import Java packages to your methods from the Imports input field, by specifying them
separated by a comma or semi-colon:
You do not need to import the packages java.lang., java.util., java.io., and java.lang.reflect. since
all message mappings require these packages and therefore import them. You should be able to
access standard JDK and J2EE packages of the SAP Web Application Server by simply specifying the
package under Import. In other words, you do not have to import it as an archive into the Integration
Repository. You can also access classes of the SAP XML Toolkit, the SAP Java Connector, and the
SAP Logging Service (see also: Runtime Environment (Java-Mappings)).
In addition to the standard packages, you can also specify Java packages that you have imported as
archives and that are located in the same, or in an underlying software component version as the
message mapping.
b. Create your Java source text in the editor window or copy source text from another editor.
4. Confirm with Save and Close.
5. User-defined functions are limited to the message mapping in which you created the function. To
save the new function, save the message mapping.
6. To test the function, use the test environment.
The new function is now visible in the User-Defined function category. When you select this category,
a corresponding button is displayed in the function chooser pushbutton bar. To edit, delete, or add the
function to the data-flow editor, choose the arrow next to the button and select from the list box
displayed.

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

ALV view : Problem with user defined views

Dear Experts,
We are facing a problem pertaining to user defined views for a ALV table that we have in SAP eRecruiting application in webdynpro ABAP. The problem is as follows.
There is a candidate application ABC & only ONE person can edit this at a time.In this application ABC there is a ALV table.
If the user clicks on this application & navigates to the ALV,this ABC application is in normal/edit mode(no one else has opened this ). So, the user can make changes in ABC. In the ALV, he can click on the 'settings 'button and save the STANDARD view as his own user defined view(by adding or removing columns).
If the user opens the application ABC in display mode(implying that someone else has alraedy opened ABC for editing), when i navigate to the same ALV,the user CANNOT see the views which were saved in the edit mode.Only the standard view is displayed. The user however has the option to again freshly save a view.
The views created by a user for this ALV should be seen irrespective of the application being opened in normal or display mode.
To add to the confusion, this problem is occuring only in some systems & not in others. There is atleast one system where the views are displayed correctly to the user.
On debugging, the table wdy_conf_user has config ids as different where the user views are stored separately for display & edit mode.
In systems where the user views are displayed correctly, the config id is one & the same ensuring that the user can see all his views irrespective of the mode of the application.
Any thoughts on how we can rectify this?
sorry for the long & tedious explanation
Thanks in advance,
Sowmya

Problems with User Defines Mapping Objects - Dynamic Configuration

We have a mapping object that takes data passed in from R3 and does an HTTP Post to another system using a URL and file name that is passed from the header record. We had a consultant set this up for us last year and in creating the new one we just pretty much copied what he did. The problem is, it is not working for us. We have the url and file name, we pass it to the user defined code that is supposed to pass it to the url and file name in the configuration. The java code looks like this:
public String getPcurlOut(String pcurl,Container container){
String ourSourceFileName = "START";
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
if (conf != null) {
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","Directory");
conf.put(key, pcurl + ".xml");
ourSourceFileName = conf.get(key);
} else {
ourSourceFileName = "conf == null";
Basically we want to pass a url and file name to our communication channel based on values that come from our file in R3
It is almost exactly like the one that works. Can anyone help with this?
Thanks
Mike

Hi Michael
Basically we want to pass a url and file name to our communication channel based on values that come from our file in R3
--> This means you have file as a sender adapter.
Check adapter specific message properties in sender adapter.
Please refer this blog , it is really worth.
/people/michal.krawczyk2/blog/2005/11/10/xi-the-same-filename-from-a-sender-to-a-receiver-file-adapter--sp14
Also
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","Directory")
Try writing this as
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName")

Problem with User Defined Second Selection Screen

Hi Gurus,
 I have a problem with the selection screen selections. My requirement is that , User when he selects a check box on the main selection screen ( which is 1000) then at the at-selection event, another screen (whose number is 2000) will be called and it has some parameters to enter values. My problem is that how to get the values from this second screen and use them in the in my program. There is an execute button on the second selection screen and when i click that, nothing is happening.
 Can anybody suggest me how to get the values from this screen which we called, and entered values in that screen. How to use these values and is there any way that we can do this.
Thanks in advance for helping me out.

Problems with user-defined update-process

Hi.
I have a small problem in the right syntax in an user-defined updated process.
The process is called by a button on the page and should update a record in a table.
BEGIN
UPDATE wam_mod_allocation SET
alloc_assessment = V('P2120_ASSESSMENT'),
last_update_date = LOCALTIMESTAMP,
last_update_staff = V('APP_USER')
WHERE username = V('P2120_USERNAME')
AND module_id = V('P2120_MODULE_ID')
END;
This is the code of the process. The line with the problem is marked bold. P2120_USERNAME is a text field in the page and contains the username to be updated.
The problem is, that the comparison doesn't work. the value "smith" is available in the table and is the same as in the text field. (both in lower case).
If I replace the part V('P2120_USERNAME') with 'smith' (with single quotes), the update statement works properly.
How do I have to compare the username with the item value that it works properly?

1. Stephan
2 + 3 Well. I enclosed both tags in the TRIM-Operator and it works. First, I thought, a whitespace caused the problems. To determine which value contains the whitespaces I removed the trim-tags on both sides. It works.
It is quite funny, because,if I remove both tags, it works too? Well. Yesterday it didnt.
To be on the safe side, I will include the trim-tags.
Thanks very much.

2.1.1 Problem with User Defined Reports with actions on the context menu

I use the User Defined Reports quite a lot, and export and publish these to other members of the team as Shared Reports. I'm also quite disappointed that there seems to be no further development in this area of SQL Developer.
One of the totally undocumented features of User Defined Reports is the ability to attach actions to a context menu, and pass data from the grid to a procedure, for example. Copying, then exporting the sessions report (from All Reports -> Data Dictionary Reports -> Database Administration -> Sessions) exposes the XML for adding actions to the context menu. The snippet for killing a session looks like this:
<item reload="true" reloadparent="false" removeFromParent="false">
<title>Kill Session</title>
<prompt type="confirm" >
 <label>Kill Session?</label>
 <default><![CDATA[]]></default>
 <value><![CDATA[]]></value>
</prompt>
<sql><![CDATA[ALTER SYSTEM KILL SESSION '#SID#, #SERIAL#' IMMEDIATE]]></sql>
<help>Kill the selected session.</help>
</item>So to add this type of functionality to your own user defined reports, you need to export the report, edit the XML, and import it again. It seems to work fine to add this to the master reports, but if you add an <item> element to the child reports, the context menu items appear on the master report too, and they are duplicated many times. I'm not sure if the action of exporting the report adds to the number of times the context menu appears.
Warning - if you edit a report using SQL Developer, all the <item> tags are removed. Once you've added actions to a context menu, you can only edit the report by exporting it, modifying the XML and importing it again.
Has anyone else seen this behavior? Have you found a work-around?
To the SQL Developer team: Are there any plans to allow the adding of user defined context menu items to reports using the GUI in the near future?

You're right the context menu needs a GUI desperately. You can request this at the SQL Developer Exchange, so other users can vote and add weight for possible future implementation.

K.

Problem with user defined selection-screens

Hi,
in my case, i have a default selection screen and a user defined selection screen. Now, after selecting a radio button in default selection screen, the user defined selection screen is called. after executing it report output is displayed. now if i press f3 (back) it is going to default selection screen. here my requirement is, when i press f3 it should go to the user defined selection.
Can u plz help me solve this.
bye n regards
sree

Any modifications to screen 1000 will be lost the next time the program is generated.
When the user hits the back key from the report output, your ABAP is restarted just like when you originally started it. That is why you are getting the default selection screen again.
Use the AT USER-COMMAND event. When BACK is hit from the report, use the SUBMIT command to re-execute the program, passing it the selections from the default selection screen. Leave out the RETURN option.
For help on filling the selection screen during SUBMIT, help is available at

Func 1: public void ChkForX(String[] a,ResultList result,Container container){
int flag = 0;
int count = 0;
for (int i = 0; i<a.length; i++)
if(aequals("X"))
{flag = 0; }
else
{flag = 1;
count = count + 1;
if(count > 0)
result.addValue("1");
else
{result.addValue("0");
Func 2:
public void ChkSpaces(String[] a,ResultList result,Container container){
int flag = 0;
int count = 0;
for (int i = 0; i<a.length; i++)
if(aequals(" "))
{flag = 0; }
else
{flag = 1;
count = count + 1;
if(count > 0)
result.addValue("2");
else
{result.addValue("3");
Kinda use both these functions with the same input then further build your logic ... but still i dont think you will get a array as output using UDF
