Java function return array of number
Hi,
I have a Java method that returns a BigDecimal[]. Already loaded it into Oracle. Now, how can I write the call spec?
I tried creating a PL/SQL table type, but I either I'm missing something or I'm doing this wrong:
CREATE OR REPLACE TYPE TRANS_TAB AS TABLE OF NUMBER;Then, the function:
FUNCTION FN_TRANS(id NUMBER, name VARCHAR2, amount NUMBER)
RETURN TRANS_TAB AS LANGUAGE JAVA
NAME 'compTrans(int, java.lang.String, java.math.BigDecimal) return java.math.BigDecimal[]';Executing this gives an error:
Error: ORA-00932: inconsistent datatypes: expected a return value that is an instance of a user defined Java class convertible to an Oracle type got an object that could not be converted
Question, how do we create the Java function with return value? Thank you. :)
Hi,
I found this example on Asktom: http://asktom.oracle.com/pls/asktom/f?p=100:11:3258786576394300::::P11_QUESTION_ID:986230504001
Looks like you have to use Oracle.sql.ARRAY and to conversion on the Java side.
Hopes this will help.

Stored Procedure: Function returns Array
I was just wondering if following scenario is possible in a stored procedure.
I have a package, which includes 4 different functions and 1 procedure. Procdure uses ref cursor to return values in my reporting tool. What I am trying to do is to write a function which takes input and return array of varchar. Something like..
Package ABC
Function student_classes (student_no in Varchar2) return [array]
begin
select class_nbr into [array]
from student_table
where student_nbr = student_no;
return [array];
end student_classes;
procedure students_info (rpt_cursor IN OUT rpt_type)
begin
OPEN rpt_cursor FOR
select
student_name,
student_nbr,
student_address,
student_classes (student_nbr) --returns array
from student_table;
end student_info; --end of procedure
end abc; --end of pacakge.
I used [array], as I am ont sure how to define (syntax) it in spec part of package or in body. I will really appreciate if someone could help me with this function.
Thank youThanks for the reply Tonguc Y.
I declared an array in my package declaration
CREATE OR REPLACE PACKAGE rpt_TESTING_pkg
AS TYPE rpt_type IS REF CURSOR;
TYPE DIAGARRAY IS VARRAY(20) OF VARCHAR2(6);
FUNCTION DIA_CODES (MNO IN VARCHAR2) RETURN DIAGARRAY;
PROCEDURE member (rpt_cursor IN OUT rpt_type);
END rpt_TESTING_pkg;
but then when I try to use it in my function it gives me error that I should declare DIAGARRAY.
CREATE OR REPLACE PACKAGE BODY rpt_TESTING_pkg
as
FUNCTION DIA_CODES (MNO IN VARCHAR2)
RETURN DIGARRAY AS diags DIGARRAY;
begin
<sql block>
end dia_codes;
end rpt_TESTING_pkg;
Any suggestions. -
Call stored function return array
Hi all,
I have a function as follow:
create or replace TYPE string_table IS TABLE OF VARCHAR2(2000);
create or replace TYPE ARRAYTYPE is VARRAY(20) OF VARCHAR2(30);
create or replace FUNCTION getEmpArray(s varchar2, t varchar2, st string_table) RETURN ARRAYTYPE AS
l_data ARRAYTYPE := ARRAYTYPE();
BEGIN
l_data.extend; l_data(l_data.count) := s; l_data.extend; l_data(l_data.count) := t; l_data.extend; l_data(l_data.count) := st(1); RETURN l_data;
END;
I want to call this function by StoredFunctionCall
code:
StoredFunctionCall fun = new StoredFunctionCall();
fun.setProcedureName("getEmpArray".toUpperCase());
Object[] arr = new Object[]{"aa", "fgfg", "bbb"};
ArrayDescriptor arrDescriptor =
ArrayDescriptor.createDescriptor("string_table".toUpperCase(),
connection);
ARRAY arrayToPass = new ARRAY(arrDescriptor, connection, arr);
fun.addUnamedArgumentValue("a");
fun.addUnamedArgumentValue("b");
fun.addUnamedArgumentValue(arrayToPass);
fun.setResult("FUNCTION_RESULT"); // for get result by this name
Vector<DatabaseRecord> list = session.executeSelectingCall(fun);
But Exception
PLS-00382: expression is of wrong type
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
Error Code: 6550
Call: BEGIN ? := GETEMPARRAY(?, ?, ?); END;
bind => [=> FUNCTION_RESULT, a, b, oracle.sql.ARRAY@21fbc01]
Please help me
Edited by: fbg on 21:52 26-04-2010A few issues,
1 - JDBC does not support the PLSQL TABLE type, you must use a VARRAY type, or wrap the TABLE function call in a function that takes a VARRAY.
TopLink also has support for PLSQL types in its PLSQLStoredProcedureCall class, but no support is currently offered for StoredFunctions.
You can't pass the VARRAY type for the TABLE argument.
2 - Your function returns a VARRAY, so you need to define this type in the StoredFunctionCall result.
We don't currently expose the API to set a Array type for the result, so you would need to access the call's first parameter directly, or use a StoredProcedureCall (and convert your function to a procedure).
You may also wish to investigate returning a cursor from a stored procedure instead of the varray.
You could also access the JDBC connection directly and perform the call using JDBC code.
Feel free to log these issues in EclipseLink.

A java function involving arrays
I need to write a simple java function that checks whether or not the elements in an array first increase up to a certain point and then decrease.
A[0] < A[3] < A[4] < ... < A[k] > A[k+1] > A[k+2] > ... > A[A.length-1]
I have no idea how to do thiscoo8 wrote:
not a clue just i know i need to use reccursion.Because you think it's necessary? Or because the assignment requires it?
for ( int i = 0; i<n; i++)
}Okay, great. That says "Do {nothing} for each element of the array." So what do you want to do for each element of the arrary?
And I still don't understand exactly what you're supposed to do. Determine whether an array first increases element by element and then decreases element by element to the end? Can it turn around at any element? Or at a specified index? Or a specified value? Does each element have to be larger/smaller than the previous by a certain amount, or just larger/smaller?
The more clearly you explain your problem, the better the help you'll get. -
Db function returning three db number columns...
Hi ,
Is it possible a db function to return three number columns fetched from a table...??
If for example , there is a db function such as...:
function x
return number
is
begin
select number_col_1 , number_col_2 , number_col_3
into var1 , var2 , var3
from table_a
where <a_condition>;
return <the_three_columns_selected>;
end;
so as in a select statement should write:
select a , b , x from a_table
many thanks ,
SimonAlternatively you can return a SQL collection:
SQL> create or replace function x (empno integer)

4 var1 emp.job%type;
5 var2 emp.sal%type;
6 var3 emp.deptno%type;
7 begin
8 select job, sal, deptno
9 into var1, var2, var3
10 from emp
11 where empno = x.empno;
12
13 return sys.dbms_debug_vc2coll (var1, var2, var3);

JavaFX : How to call java function that returns hashtable and manipulate
I have a requirement to {color:#0000ff}create a java object in JavaFX script code{color}. Then call a java function using the created java object. The java function returns hashtable. Then traverse through each element of hashtable. Finally I need to create a similar structure in JavaFX.
If you need to use a Java class that uses generics you need to take special steps. Since JavaFX does not support generics you need to create a java wrapper to hide the calls that use generics and call the wrapper class from FX.

Can Evaluate function return object type
Hi
Evaluate function can be used to call db functions in OBIEE. I have a function which returns an object ( pl/sql table).
Created a simple report in Oracle Answers and added following in one of the columns
evaluate( 'get_ccid(%1)' as t_ccid , @{p_request})
When I try to run this in Oracle answers, getting syntax error. If same function returns varchar or number it works well.evaluate( 'get_ccid(%1)' as t_ccid , @{p_request})Eakta, You syntax seems to be wrong here. What type of data your presentation variable contains here ?? You are saying its working fine with Number datatype..so can you try..somthing like below with some default value..
EVALUATE('get_ccid(%1)',@{p_request}{2})
OR
EVALUATE('get_ccid(%1)' as varchar(250),@{p_request}{ABC})
Also, refer

It is comparing the selected value against the List<SelectItem> returned by getSetoresOrigem() as it is during the apply request values phase of the form submit request.Ok. That's what I supposed JSF was doing.
BalusC wrote:
If the selected value isn't in there, then you will get this error.I can understand this, but is this right? As I said, the old value isn't really there because I changed the list values to new ones. But the new value (the value of fSetorOrigem ) corresponds to a value that exist in the new list items, so a valid value. So JSF is not considering that I also changed the list, not just the value. It is comparing the new value with the old list, not the new one. Acting like this JSF is making the page looks like a static HTML page, not a dynamic one. If I can't change the list and the value, what's the point of that? In my point of view I'm not doing anything wrong, I'm not violating any JSF rules.

How to return array of String to a java program.! ??
Hi All,
I am new to JNI programming. so trying with simple example. I am having one problem. I have one array of String in my Java program. I want to reverse all the elements in this array and want back this new array in the same form i.e. array of string. So how can I do this ??
Please guide me.....
The function of defination of array in my java code is
public native String[] getReverseStringArray(String[] arrString);
where as my array is like:
String[] arrStr = {"one", "two", "three", "four", "��������","�c��","�J�^�J�i"};
and I am calling function in C file like:
arrStr = employee.getReverseStringArray(arrStr);
and the function defination in my c file is
JNIEXPORT jobjectArray JNICALL
Java_Emp_getReverseStringArray (JNIEnv *env, jobject obj, jobjectArray arr)
// some code will come here......
So can anybody tell me how to do this ??
Thanx in advance...
Pandurang
[email protected]Hi,
this is quite simple. Here an example function that works like this:
JNIEXPORT jobjectArray JNICALL Java_cadagent_ugopen_UgAssembly_jni_1getStructure
(JNIEnv *env, jclass cls, jstring part)
jobjectArray retvals = NULL;
jstring j_val = NULL;
int child_count = 5;
/* initialize return array */
j_val = (*env)->NewStringUTF(env, "");
retvals = (*env)->NewObjectArray(env, child_count, (*env)->FindClass(env, "java/lang/String"), j_val);
for (i=0;i<child_count;i++)
j_val = (*env)->NewStringUTF(env, "some text");
(*env)->SetObjectArrayElement(env, retvals,i, j_val);
return retvals;
Hope this answers you question. -
Return array of varchar from oracle to java
Hi,
I am trying to return an array of varchar from database to java. However, when I print the values in java, it prints hexadecimal values like this.
0x656E7472792031
0x656E7472792032
0x656E7472792033
0x656E7472792034
I am using oracle 9.2.0.5.0 and jdk 1.4
This happens only when the NLS character set of the database is WE8MSWIN1252 (default character set).
It works fine on databases with UTF8 and US7ASCII character sets.
Any leads to the reason behind this behaviour is greatly aprpeciated.
Here's the code snippet...
<code>
//USER DEFINED TYPE
create or replace type SimpleArray
as table of varchar2(30)
</code>
<code>
// FUNCTION RETURNING USER DEFINED TYPE
create or replace function getSimpleArray return SimpleArray
as
l_data simpleArray := simpleArray();
begin
for i in 1 .. 10 loop
l_data.extend;
l_data(l_data.count) := 'entry ' || i;
end loop;
return l_data;
end;
</code>
<code>
// JAVA METHOD
public static void main(String[] args)
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
String url = "jdbc:oracle:thin:@localhost:1521:db1252";
Connection conn = DriverManager.getConnection(url, "ring", "ring");
CallableStatement stmt = conn.prepareCall("{? = call "
+ "getSimpleArray" + "}");
Array rs = null;
ResultSet rsltSet = null;
stmt.registerOutParameter(1, Types.ARRAY, "SIMPLEARRAY");
stmt.execute();
rs = stmt.getArray(1);
String[] values = (String[]) rs.getArray();
System.out.println(rs.getBaseTypeName());
System.out.println(values.length);
for (int i = 0; i < values.length; i++) {
System.out.println(values);
rsltSet = rs.getResultSet();
} catch (Exception e) {
System.err.println("Got an exception! ");
System.err.println(e.getMessage());
</code>
Thanks,
VivekActually, check nls_charset12.zip. It looks like 9.2.0.5 driver contains only the *.zip version. Make sure that the file exists in the directory pointed by the CLASSPATH. Use full path, do not use %ORACLE_HOME%.
I have reproduced your problem without nls_charset12.zip and I could not reproduce it with the file in the class path. Double-check how classpath is set in your environment. Maybe it is overriden by some configuration or batch file.

Using jdbc StoredProcedure to return from a function an array of objects
I am trying to call a stored procedure(function) using jdbcTemplates with no inputs which returns a list of objects.
I previously used the same function returning a cursor and used the following example:
http://www.saarathi.com/wiki/Processing_JDBC_ResultSet_from_an_Oracle_stored_procedure_with_Spring#Calling_the_stored_procedure_and_function_from_Spring_JDBC_DAO
which worked fine.
I now want to return the same objects which relates to a table but in a list and have tried to follow the example in
http://forum.springframework.org/archive/index.php/t-10042.html
But have had no success and did not understand the example GetPersonProc.
I dont understand why it works for the cursor and not a list.
I would very much appreciate some help.Hi

Whee the function return the value store in java
in c if i write this program

if i run this program it give s error that lvalue required
but in java it works fine though the function return some valuein c if i write this program
int add()
return 1;
main()
add();
if i run this program it give s error that lvalue
requiredYou mean, if you try to run it as a C program it gave an error?
Then take your question to a "C" discussion forum. This is Java.

In Java this does NOT work fine.
It definitely does not compile! So you cannot run it. -
