Wrong value in java stored function

Hi All,
i have written a java stored function,
at the end of the code it insert record into the database
among other columns also a number(18,3) column,
when I debug it (out side of server) - works fine.
when I load it to database i get wrong values in column
(like instead of 76.546 i get 77.667) I can't figure out where it comes from.
I use big decimal in java code.
if i Hard code the value in java code it works fine!
am I missing something ?, calculations/ data type different out side then inside database? using oracle 10.2.0.2
Cheers
Sahar

Hi
the code calculate some averages of amounts ( money) according to several
conditions,and parameters given to the function and stores the average into table in the database
the money columns are of data type 18,3 , both source and target tables have same structure.
thanks
Sahar

Return 2 values (string, number) multiple rows, from java stored function

I would like to return 2 values (String, number prefered but String, String will work) from a java stored function.
I was able to successfully return a varray of varchar2 values but I was wondering if it is possible to return 2 values by using a varray?
Is it even possible? I tried using combinations of types which included a varray of objects (with 2 attributes) or a type as table of objects but I couldn't figure out how in my java code to set these values. Also what would my java function return type be and what Oracle type would map to it?
Any help and examples or pointers would be great.
Thanks,
Dennis

Thanks to all. I finally figured it out through all the pieces on the web.
Here is what worked for me. First create 2 oracle types. One object type to represent the "columns" I will pass back:
CREATE OR REPLACE TYPE COST_OBJ AS OBJECT (COST_NAME NVARCHAR2(50), COST_VALUE number ) NOT FINAL
note: make sure the "strings" are defined as NVARCHAR2 or Java will puke if it is just VARCHAR2.
Then create a table type to hold your objects defined as following:
CREATE OR REPLACE TYPE COST_OBJ_TABLE is table OF COST_OBJ
Then create the oracle stored function that is a wrapper to the java function:
CREATE OR REPLACE FUNCTION get_Costs(Name VARCHAR2, evalDate VARCHAR2, fuelCodeID NUMBER) return COST_OBJ_TABLE
is language java name
'com.costs.storedProcedures.Cost.getCosts(java.lang.String, java.lang.String, int) return oracle.sql.ARRAY'
Once that is done, Oracle is ready. The Java function looks something like this:
public ARRAY getCosts(String name, String evalDate, int fuelCodeID) {
DBAccess da = getDBAccess();
// get a handle on the connection
Connection conn = da.getConnection();
// The stuff that will be returned should be as type object array
// make it to the size of the number of fuelcomponents passed in
Object[] returnStuff = new Object[3];
// create the type of struct that is defined on the database
StructDescriptor structDesc =
StructDescriptor.createDescriptor("CY_UMAP.COST_OBJ", conn);
for (int i = 0; i < returnStuff .size(); i++) {
Object[] costValues = new Object[]{
     "This is object " + i,
     new Integer ( i ) };
STRUCT cost_obj = new STRUCT(structDesc, conn, costValues);
returnStuff[i] = cost_obj;
ArrayDescriptor x_ad = ArrayDescriptor.createDescriptor (
"CY_UMAP.COST_OBJ_TABLE", conn);
ARRAY x_array = new ARRAY(x_ad, conn, returnStuff);
return x_array;
I hope this helps others.

Why returning string from java stored function failed ? HELP ME, PLEASE

Hi everybody,
I created java stored function: it's doing http post, parsing xml from http reply, and returning string result.
Sometimes, it doesn't return any value. What can be a reason ?
The high level procedure, has following form:
class SBE {
public static String call(String arg0) {
SBE sbe=new SBE("d:\\oracle\\ora81\\network\\log\\SBE.log");
String result=SBEParser.go(sbe.sendRequest(arg0, ""), sbe.logger);
sbe.logger.log(result);
sbe.logger.log("Finish SBE intetraction");
return result;
PLSQL wrapper has a simple form:
create or replace package PG_SBE as
function CALL(arg0 in varchar2) return varchar2;
end;
create or replace package body PG_SBE as
function CALL(arg0 varchar2) return varchar2 as language java name 'SBE.call(java.lang.String) return java.lang.String';
end;
In log file ("d:\\oracle\\ora81\\network\\log\\SBE.log"), I can find message :
"Finish SBE intetraction"
but query:
select pg_sbe.call("any argument") from dual;
doesn't finish.
What can be a reason ? What can I do to trace stage of convertion java string to varchar ?
Please help me...
Best regards
Marek

This comes up periodically. It just isn't possible using that type of approach. Probably the best you could do is the create an ADT (containing collections) and use that to pass a 'batch' of information.
Hopefully this will get addressed in the next release of the database.

Recursing through table / complex return types in Java Stored Functions

I have a table representing a tree with arbitrary depth, of the form:
ID NUMBER(10) PRIMARY KEY,
NAME VARCHAR2(20),
PARENT NUMBER(10)
with PARENT being a foreign key for ID, so that top-level nodes in the tree have a NULL PARENT, and other nodes have the ID of their parent node in the PARENT field.
I want a good way to get a row representing a node as well as all its ancestor nodes recursively up to the top level. I do this a lot in my Java application, and right now it works by just getting each row, checking if PARENT is null, and recursing again until I get the top-level node. Since this recursion is in Java and I do multiple queries it's rather slow, and I'd rather perform this operation in the database (using a Java Stored Function/Procedure or PL/SQL).
I'm no good at PL/SQL so don't have a clue how to go about doing this sort of thing, and although I can write a Java Stored Function that does the same recursion I do in the application, I don't know how to return the results. I can't return a REF CURSOR type since the results are from multiple queries, and I can't find any documentation about how to return structured types from a JSF.
If anyone could give me a near-complete PL/SQL listing that does this or (better) help me to complete my Java Stored Function by returning the results in a structured type.

You are my own personal God (for the day). Thanks, exactly what I needed, and all in one query with no procedural.

How to return custJava Object from Java Stored Function/Procedure to Java Application

I WILL PAY $100 FOR SOLUTION.
Oracle JDBC documentation gives step by step on how to return Oracle Type Object to Java Application. No question here.
But is it possible to create Java Stored Function [getMyClass() ] which returns CUSTOM Java based object [MyClass] to Java application like:
//java stored function
class Foo
public static MyClass getMyClass()
return new MyClass();
//java class I want to return to Java
class MyClass
public String getGreetings(String name)
return "Hello " + name;
I tried to do it using intermittent Oracle
Type Object and OracleConnection map to make binding between Java->Oracle->Java. I could
not get throgh meaningless run time ORA Errors. Any kind of help would be greatly
appreciated. If you know the answer please
post it or e-mail [email protected]

You don't say which version of the database you are on. There's an interesting looking article on OTN on handling CLOBs in JDBC in 10g. It may well be useful for earlier versions too (but no guarantees).

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 )

Thank you for the quick response!
Does it work for you? I tryed getElementsByName("myform:myRadio")[1].value="1"; No errors but the screen doesn't show that radio button is "on". I also created another function to go through the form object and try to set the attribute but no luck. From screen, I still don't see the option is selected(or on). I have :
<script .... >
function checkRadioButton(){
var allElem = document.forms['myform'].elements;
for ( i=0 ; i< allElem.length; i++ ){
alert("element name = " + allElem.name ); // I see myform:myRadio three times
alert("element id = " + allElem[i].id ) // when name="myform:myRadio, id is null/empty
alert("element value = "+ allElem[i].value ); // when name="myform:myRadio, value = 1, 2, 3 respectively
if ( allElem[i].name == 'myform.myRadio' ) {
     var attributes = allElem[i].attributes;
for ( j =0; j < attributes.length; j++) {
          if ( attributes[j].name == 'CHECKED' ) { // I found CHECKED is one of selectOneRadio's attributes
               if ( i == 1) {
     attributes[j].value = true; // It still doesn't work. I didn't see that option1 get selected/on.
What I am trying to do is common, I think !!?? Really appreciate your help.

Read item from Java class and call to stored function/procedure of database

Hi,
I am looking solution that I was trying to find becasue of I am not expert and novice of ADF so I am getting problem to do. I am trying migrating from oracle forms to JDeveloper[ADF].
I want to call database stored function from JSF pages by java bean class of a button press event (manually created) and after button event I have called java class which I created manually. But I can not read that values what I given into jsp page.
question1: How can I read jsp pages items value to java class ?
question2: How can I call to database stored function/procedure with that parameter?
question3: How can I use return value of that stored function/procedure ?
Please reply me .

Getting result of stored functions in UCM components

Hi,
I have to create UCM component that executes function stored in DB and somehow "inject" it's return value to iDoc.
How can I get return value of DB stored function?
I managed to run the function, but I can not get it's return value.
The only documentation I found is inside "documentation" folder from HowToComponents bundle, but there is no even javadoc for executeCallable that returns CallableResults.
The queries I used are:
{ ? = call package.func(?) }
or
BEGIN ? := package.func(?); END;
I added 2 parameters to these queries ( in queries html file)
In both cases the function gets executed (I see changes in DB)
after the execution I try to getInteger("param1_name") on returned CallableResults and recieve NullPointerException:
Runtime error: java.lang.NullPointerException
at oracle.jdbc.driver.OracleCallableStatement.getInt(OracleCallableStatement.java:1119)
at intradoc.jdbc.JdbcCallableResults.getData(JdbcCallableResults.java:203)
at intradoc.jdbc.JdbcCallableResults.getInteger(JdbcCallableResults.java:98)
at DatabaseProvider.DatabaseProviderHandler.executeReservation(DatabaseProviderHandler.java:224) <------ calling getInteger("param1_name")
the param1_name is not changed in iDoc.
Thanks.

Hi,
you can do this with just one script object.
For example the "MyTexts" script object with the string variables and a function to return the values.
var infotext1 = "Lorem ipsum dolor sit amet"
var infotext2 = "Non eram nescius Brute cum"
function getText(FieldNumber) {
return eval("infotext" + FieldNumber);
To populate a field you can call the function in the script object with an argument, which is the alias for the varaible number you want to return.
You don't need to enter the full somExpression to your script object, the name is enough.
Textfeld1.rawValue = MyTexts.getText(1);

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?

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.

Java stored proc. malformed values in numeric Datafield ...

The java stored procedure functiones well, if it access tables that are on the same server.
Retrieving Data from numeric field of a resultset will result in malformed numeric values , if the table I access it on another server.
like sms.tabname@server.
No matter , which methods I use
rset.getBigDecimal , rset.getFloat /these will retrieve sometimes values with 20 to 40 digits!.
Maybe some NLS related problem ?

Java Stored Procedure functions in SQL DML - multiple invocations

When running a java stored procedure as part of a DML statement the procedure is invoked 10-15 times for each row that is updated.
For example:
Update mytable set mycolumn = myjsp(somecolumn);
I undertand that this was a known bug with the JDBC driver. Has it been fixed? Is there a workaround?
We are using 8.1.6 on NT 4

for (int z = 0; z < bindVars.length; z++) {
// 4. Set the value of user-supplied bind vars in the stmt
st.setObject(z + 2, bindVars[z]);
// 5. Set the value of user-supplied bind vars in the stmt
st.executeUpdate();
// 6. Return the value of the first bind variable
return st.getObject(1);
catch (SQLException e) {
throw new JboException(e);
finally {
if (st != null) {
try {
// 7. Close the statement
st.close();
catch (SQLException e) {}
With a helper method like this in place, calling the func_with_no_args procedure shown in Example 37-7 would look like this:
*2) In class CustomServiceImpl extends CustomApplicationModuleImpl*
public String callEnvironmentName(){
return (String) callStoredFunction(VARCHAR2, "CAR_UTIL_PK.get_environment_name()", new Object[] {});
3) If I have the first two steps correct, I was to display the value returned by method callEnvironmentName() with scalar values like (Development, Production etc) at the footer of each JSFX page. What is the flow I should follow, should I call callEnvironmentName() from some managed bean? Also I want to store it once on first call to some application variable and use that to populate the JSFX pages. Is there a working example. What is the best practice?
Thanks

Hi John,
Duplicate alerts are coming for BP_Confirmed as well as one custom event. Earlier I thought there is some issue with my custom event, but when it came for BP_Confirmed also, then i have a doubt something is wrong with the application.
I have also checked that BP_Confirmed is being raised only once inside the method-BP_CONFIRM of class-cl_crmcmp_b_cucobupa_impl.
raise event BPConfirmed
CLASS cl_crm_ic_services DEFINITION LOAD.
CREATE OBJECT event.
event->set_name( if_crm_ic_events_con=>gc_bpconfirmed ).
event_srv = cl_crm_ic_services=>get_event_srv_instance( ).
event_srv->raise( event ).
Are you aware of any other place from where this event is getting triggered?
Thanks for your help!
Regards,
Rohit
