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

Update the logon date user via a function

Hi,
I use a web application (webdynpro ABAP) what is connected via RFC at a R3 system. At each connexion of the user, I must update this logon date on R3 system. What is the used function or BAPI to update the user logon date?
Thansk in advance.

Hi,
I suggest using Administrator account to change the "Due Date" for testing.
If Administrator can edit it, it seems the permission issue. I suggest re-granting the permissions to the user.

Adding Members (not Users) via registration form, so they can post info to site?

I would like to create a simple, free Registration form (name, email address, choose password) to create a 'Member' in database, who can then log in to add content to the web site. How would I accomplish this?

View + stored function + synonym for other user

Dear All!
I've got a quite strange problem which I cannot decide whether it's caused by my lack of knowledge on the appropriate topic or by an Oracle bug. I'm already after some heavy googling on the topic and I was unable to track any valuable answers neither in forums nor in the Oracle documentation. I'll try to be as short and specific as possible.
Database: Oracle 10g
Result of "SELECT BANNER FROM V$VERSION":
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
PL/SQL Release 10.2.0.4.0 - Production
"CORE 10.2.0.4.0 Production"
TNS for Solaris: Version 10.2.0.4.0 - Production
NLSRTL Version 10.2.0.4.0 - Production
I have two users in the database for a single Web application: UAPP01, which is the owner of application DB objects and UAPP02 which is the application user connecting to the DB. The application runs for quite many years by now and DB structure layout has always been following a simple logic: for each DB object used by the app. (tables, views, packages and stored procedures/functions) and found in the UAPP01 there exists a synonym in the UAPP02 schema. For the privileges to be set correctly a role is created: RL_MY_APPL which is granted the necessary privileges on objects of UAPP01 (CRUD on tables, SELECT on views, EXECUTE on procedures, etc..). This role is granted to UAPP02.
In the previous days I was about to extend the DB with a view that invokes a stored function. This pattern has already occured in the DB previously so I kept following existing conventions: I've created the stored function and the view in the UAPP01 schema, granted SELECT on the view to RL_MY_APPL and created the synonym for it in the UAPP02 schema. This is where the entire functionality began to act strange. I'll try to explain with a simplified example that was sufficient to reproduce the problem:
REM ========================================
REM Execute below code as UAPP01 user.
REM ========================================
REM Test function.
CREATE OR REPLACE FUNCTION testfunction(p_param NUMBER) RETURN NUMBER IS
BEGIN
RETURN p_param *2;
END;
REM Testview version 1. causing trouble.
CREATE OR REPLACE VIEW testview AS
WITH testdata AS
SELECT /*+ materialize*/ LEVEL AS d
FROM dual CONNECT BY LEVEL <= 100
SELECT a, b, c, SUM(d) AS sum_d
FROM
SELECT FLOOR(dbms_random.VALUE(1, 100)) a, FLOOR(dbms_random.VALUE(1, 100)) b, FLOOR(dbms_random.VALUE(1, 100)) c, testfunction(d) AS d
FROM testdata
GROUP BY CUBE(a, b, c)
REM Testview version 2. not causing trouble.
CREATE OR REPLACE VIEW testview AS
SELECT a, b, c, SUM(d) AS sum_d
FROM
SELECT FLOOR(dbms_random.VALUE(1, 100)) a, FLOOR(dbms_random.VALUE(1, 100)) b, FLOOR(dbms_random.VALUE(1, 100)) c, testfunction(d) AS d
FROM
SELECT LEVEL AS d FROM dual CONNECT BY LEVEL <= 100
GROUP BY (a, b, c)
REM Synonym.
CREATE OR REPLACE SYNONYM UAPP02.testview FOR UAPP01.testview;
REM Grants.
GRANT SELECT ON testview TO RL_MY_APPL;
When creating TESTVIEW with the 1 ^st^ version I cannot query it using the UAPP02 user, I'm constantly getting the error: ORA-00904: : invalid identifier. However, when I use the 2 ^nd^ version everything runs perfectly. What is common in the two cases is that both versions use the TESTFUNCTION function. I have not granted the EXECUTE rights on TESTFUNCTION to the RL_MY_APPL since it was never needed previously (for other views using stored functions) and as far as I know it's not necessary (as both the view and the function are owned by UAPP01). The strange thing in the above behaviour is that the function is used by both versions, however only one of them fails. This is where I thought it's not a granting issue, otherwise neither of the versions would have worked and I think I would have received a different error stating that UAPP02 lacks the necessary privileges on underlying objects of the view.
As I further digged into the problem by examining the EXPLAIN PLAN output for the two versions I found that version 1. leads to a TEMP TABLE TRANSFORMATION and to MULTI TABLE INSERTs, whereas version 2. simply executes the query without doing such things. In my setup I presume the MULTI TABLE INSERTs were caused by the GROUP BY CUBE. When I simply removed the CUBE and used only GROUP BY the TEMP TABLE TRANSFORMATION remained in place but the MULTI TABLE INSERTs disappeared. As a result of this small modification the view again began to work when I executed it through the synonym and using the UAPP02 user.
With the original DB objects of our application the behaviour is even more strange: the error comes up if I select from the view and filter for a column that is grouped in the query whereas it works correctly if I filter for the aggregated columns. However, I couldn't reproduce this with the above simplified example.
No problem occurs with any of the versions if I query the view using the UAPP01 user.
This hectic behaviour made me suspect that the TEMP TABLE TRANSFORMATION + MULTI TABLE INSERT + synonym + stored function combo appears to bring a strange Oracle bug to the surface...
As a final note: when executing GRANT EXECUTE ON TESTFUNCTION TO RL_MY_APPL everything works fine in all cases. I know I could simply live with this but I'd really like to get to the bottom of this. Although this extra GRANT appears to solve the problem I don't really trust it. I'd really like to avoid the bug emerging again in Production in case this extra GRANT were not sufficient due to some unknown misteries.
Excuse me, the post has become a bit lengthy. Thanks in advance for anyone who's willing to read through and answer it!
Regards,
Krisztian Balazs Szaniszlo

The error is thrown at run-time and only for the UAPP02 (second) user.
The problem is that the appearance of errors is independent of whether the query contains the call to the stored function or not.
So far I thought that if I use a stored function indirectly, like in this setup: UAPP02.synonym -> UAPP01.view -> UAPP01.stored function, then I don't need the grant. Of course, I understand that if I had used it directly, like :UAPP02.synonym -> UAPP01.stored function then I'd need the GRANT EXECUTE.
Shall I just ignore the strange behaviour and go on by adding GRANT EXECUTE privilege on all the functions used indirectly through views? It seems to solve the problem, but this behaviour is disturbing me quite and I fear the real root cause of the problem can emerge later in a different fashion.

Can't modify users via commadmin or DA after adding services

after adding the following services
Authentication Configuration
Instant Messaging Service
Presence Service
i cannot modify users via commadmin (string index error -6) or via the DA (save operation failed) nothing in the slapd logs (error or access) - after removing these services i can modify via the DA.
is this a known bug (or a feature?).
after modifying, i can re add the services and proceed as normal.
thanks,
s7

you can try what worked for me:
remove services from user (in amconsole web app http://jes-server/amconsole) -
login as admin, search specific user, see their services, remove them -
run your commadmin command - it should work now
re-add the removed services.

Adding prompts dynamically and then send the results to users via email

Hi,
We have to schedule the reports for auto delivery to users at a specific time period. Please, tell me the mechanism to schedule them and how to assign prompt values to them. Currently, the reports are run by users by selecting prompts from the dashboard. If we schedule them, we will have to add some of these prompts dynamically and then send the results to users via email.
Thanks in advance!

Hi,
I haven't tested it myself...but may be the following steps can help you.
Fill some session variables depending on the the name of the user who logs in (this can be done easily be creating different session variables and put some executing order in it)
Then you use these session variables as default values for your prompts. So the report will be executed making use of this default values.
And by scheduling your ibot..you can send it by mail.
I don't know if it's this what you're looking for...probably you have to base your prompt values depending on the users that are selected in your ibot?
Hope it can help y ou in some way or another...

Difference between Stored Procedure & Stored Function

I want to know the difference between Procedure Procedure & Stored Function in compiler in oracle 10g.
Thanks in advance

I've been guilty of doing that myself but you can put a when others exception in a procedure also :-)
You can have an issue in forms triggers where it throws an exception for no known reason and the only way to throttle it is to have the everything exception. I think there is a bug in there that is exposed under some circumstances and everyone has run into it, that's my theory. You're definitely right that having the everything exception in the code leads to impossible to debug problems. I think we could use some error handling enhancements.
I'd like to see an all-purpose error function in forms. Instead of the customer having to program to catch all the various kinds of errors that can occur, plsql, database, forms, .... I'd like to be able to configure the form to have a built in error handling system show the error with an option to programatically handle the error unseen. The forms thing that it shows errors on the bottom of the screen does not work at all in my experience where we deploy forms. Windows by default has large icons and they cover up the error area. Even if you get the user to change the icons to small the users never see those messages. And they will not display errors in forms via the help menu either. (help,display error). I would like to be able to filter error messages, translate error messages with some kind of translation table (make user understandable), and have them pop up on the screen in a window.
I think some of the database functions that are "error-happy" should be provided in additional constructs. It is a design decision to have this throw an exception when the record doesn't exist:
select mycolumn into myfield from sometable where mykey = 'X';
I think many of us would prefer to have it simply not throw an exception if the record doesn't exist, so we don't have to remember what on earth the exception was called, and test the results of myfield and/or a status field.
How else to do this? How about this?:
minselect mycolumn into myfield, mystatus from sometable where mykey = 'X';
Here we define a new form of select called minselect that is reluctant to throw exceptions, but puts a status code in
the status field should someone have to know the difference of whether myfield was null in an existing record or if there was no qualifying record.
What's with the minselect? Well we would have a minselect and a maxselect that would find ONE qualifying record, the min or the max to get around that exception problem #2, select returning multiple values. (We would have the status reflect the fact there were multiple values.)

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 ..

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.

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)

Problem with return value of stored function

Hi,
I've made a stored function that insert a new row in a table and return the primary key (see at the end of the message the function script).
In VS 2005 with Visual basic, using the designer, I've created a dataset containing a tableAdapter to be able to use the Pl/SQL function.
My problem is I can't get the proper return value. The VB code below works without error except that I get 0 as value.
What's wrong?
Cheers,
Sebastien

Dim myAddSession As New ICISDataSetTableAdapters.AddSessionTableAdapter
Dim intSessionId As Integer
intSessionId = myAddSession.ADD_SESSION(tbxUsername.Text, _
tempFolder.Substring(tempFolder.LastIndexOf("\") + 1), _
"toto", Environment.GetEnvironmentVariable("COMPUTERNAME"), _
myLevelAccess.icisUserId, myLevelAccess.levelId)
The debugger tells me that the ADD_SESSION function return value is Object.

CREATE OR REPLACE FUNCTION ICISSEC.add_session (

Nope, can't do that in the signature. You'll need to handle that by validating the passed parameters at the start of the function.
It's simple enough. In your case you might just as well test for NULL and fail the function like this:
    FUNCTION date_post_message(
            user_lock_in IN NUMBER,
            form_type_in IN NUMBER DEFAULT 0 ,
            date_in      IN DATE)
        RETURN BOOLEAN
    IS
        v_num NUMBER(1);
    BEGIN
        dbms_output.put_line('Value of parameters : user_lock_in : '||user_lock_in || ' : form_type_in : '||form_type_in||' : date_in : '||date_in );
        IF user_lock_in = 1 THEN
            RETURN FALSE;
        END IF;
        IF form_type_in IS NULL THEN
            RETURN FALSE;
        ELSIF form_type_in NOT IN (1,2) THEN
            RETURN FALSE;
        END IF;
        RETURN TRUE;
    EXCEPTION
    WHEN NO_DATA_FOUND THEN
        RETURN FALSE;
    END;In other use cases I would declare a local variable and process it like this:
        IF form_type_in IS NULL THEN
            l_form_type := 0;
        ELSE
             l_form_type := form_type_in;
        END IF;Obviously the code should use the local variable rather than the parameter.
Validating the values passed in parameters at the start of a function is good practice. If you really want to go to town, read about Design By Contract.

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,

Using Stored Function with a datagridview

Hi All,
I have a problem using a stored function in a datagridview control. My problem is, when the user adds a new row to the grid, the stored function is called to insert the next item number in a grid column. For some reason I cannot figure out why this isn’t just working. The stored function is working alright, as I can call it from SQL Plus or PL/SQL and get the return value back but my problem is inserting it into the grid as the user creates a new row. Can some please help.
Function NextItemNum RETURN NUMBER
IS
varItemNum NUMBER(8);
Begin
SELECT MAX(ITEM_NUM) + 1
INTO varItemNum
FROM ORDERITEMS;
IF varItemNum IS NULL THEN
varItemNum = 1
END IF;
RETURN varItemNum;
END NextItemNum;
/* Code to insert into datagridview */
ig = myOrdersInsertCommand.Parameters.Add(New OracleParameter("pVal", Client.OracleDbType.Int32, 8, ParameterDirection.ReturnValue))
myOrdersInsertCommand.ExecuteNonQuery()
ItemNum = (myOrdersInsertCommand.Parameters("pVal").Value.ToString())
For Each r As DataGridViewRow In OrderItemsDataGridView.Rows
ORDER_ITEMSTableAdapter.InsertOrderItems(r.Cells(0).Value, r.Cells(1).Value, r.Cells(2).Value, r.Cells(3).Value, r.Cells(4).Value, r.Cells(5).Value, r.Cells(6).Value)

Firstly, thank you for the help. I have attempted to code the advice you gave but it still does not seem to compile properly. Can you suggest what is wrong with my code please?

How to return fillable pdf form via distribute function in live cycle?

I am trying to have a fillable form be submitted back/returned by e-mail (through using outlook)to multiple users, via the distribute form function through livecycle, so that they know a pdf form has been completed and sent back and that I can place the information in the dataset as well (in case I need to export the info). Currently the distribute function only accepts it going to one e-mail, even if I seperate the e-mails with a ";". How do I have the form e-mail multiple users and allow me to place the form field data go into a dataset via distribution?

I tried it and I am seeing what you are seeing. If I send to a single user then it works fine. I think it might be outlook blocking the multi-address through programmatic interfaces. They do this so that viruses cannot turn your mail client into a spam generation. This is simply a guess.

How can i return a SDO_GEOMETRY value in a Java-Stored-Function?

For a example, Ive got a java-function witch returns a
oracle.sdoapi.geom.Geometry like:
public static Geometry GetQPoint(String sF_TABLE_NAME, long lFID)
And now, Ill try to deploy this function as a PL-SQL stored-function like:
GET_Q_POINT(
F_TABLE_NAME IN VARCHAR2,
FID IN NUMBER
) RETURN MDSYS.SDO_GEOMETRY;
I can't deploy this above mentioned java-function with Oracle9i JDeveloper because oracle.sdoapi.geom.Geometry can not mapped in any PL-SQL data type.
Is there any possibility to do it in a other way?
Please help me.

a quick example that takes as input a longitude and latitude,
and return a point geometry in wgs 84:
CREATE OR REPLACE FUNCTION get_geom (
     longitude IN          NUMBER,
     latitude     IN          NUMBER )
