Declare a varray in a function

hello,
i wanna know how declare a varray of number(13,3) in a function, without declaring it as a new type
regards
Elyes

Just declare type in your function. E.g.:
CREATE OR REPLACE
FUNCTION F1
    RETURN NUMBER
    IS
        TYPE varray_numbers IS VARRAY(35) OF NUMBER(13,3);
        v_varray varray_numbers := varray_numbers();
    BEGIN
        v_varray.extend(5);
        v_varray(5) := 5;
        RETURN 1;
END;
/SY.

Why do I have to declare my int outside the function?

`Hi!
I've writen the very simple class get_results with one methode test:
public class Get_results {
   protected int nb=0;
public int test(int numb) {
         //int nb=0;
         nb=numb;
         return nb;
           }//End test
}//End classthis methode will be called from a jsp file:
<jsp:useBean id="results" scope="session" class="mypackage.Get_results" />
<%= results.test(3) %>I don't understand why I have to declare int nb outside the function test. If I declare int nb at the beginning of the function and not right at the beginning of the class
public class Get_results {
public int test(int numb) {
         int nb=0;
         nb=numb;
         return nb;
           }//End test
}//End classthe it doesn't work. I don't understand why since I only need the int nb in the test methode and nowhere else in the class.
can anyone explane this to me?
thanks.

HOWTO: Declare a variable within a function.

I'm having a hard time declaring a variable within a function. This is my code:
CREATE OR REPLACE FUNCTION schemaName.functionName (inParam VARCHAR2(20))
RETURN VARCHAR2 IS VARCHAR2(10)
BEGIN
DECLARE paramLength NUMBER; --This is not working. The docs do not state what the size of the number returned by LENGTH is.
SELECT LENGTH(inParam) INTO paramLength FROM DUAL;
IF paramLength < 10 THEN
RETURN '';
ELSE
/* Clean up the value */
RETURN inParam
END IF;
END;

In relation to your own code...
CREATE OR REPLACE FUNCTION schemaName.functionName (inParam VARCHAR2(20)) RETURN VARCHAR2 IS
paramLength NUMBER;
BEGIN
/* Clean up the value */
paramLength = LENGTH(inParam);
IF paramLength < 10 THEN
RETURN NULL;
ELSE
RETURN inParam
END IF;
END; You don't need to use SQL to determine the length of a string.

Custome BAPI - declare ITAB and define the Function Module and Subroutine

Hello Experts
I want to create a Custom BAPI and it has the following scenario:
1) a Function Module which collects some records into it internal table, say ITAB
2) a Subroutine which moved the records from ITAB to BAPI table
Now, I want to declare ITAB and define the Function Module and Subroutine.
Where and How can I do this?
Plz suggest.
Regards
BD

Hi,
1) Got to SE37 and create an RFC .
2) Declare the ITAB directly in the TABLES tab of the FM.
3) Inside the FM source Code tab, collect all the data using SELECT query and directly or by using logic, put the data into the
      ITAB.
4) Since the data collected is directly put into the itab you dont need a subroutine to be written.
5) If subroutine is a necessity, then just write PERFORM SUB ROUTINE NAME.
       AND DEFINE THE FORM ENDFORM OF THE SUBROUTINE AFTER THE ENDFUNCTION OF THE FM
   Let me know if any issues....
Regards,
Vimal.

Constant declaration of VARRAY index by varchar2 within package header

Hi there
I'm looking for the correct syntax to declare a constant
of a varray type which is indexed by varchar2. I've tried
the following:
create or replace package nl_types
is
    TYPE nt_assoc_small IS TABLE OF INTEGER INDEX BY VARCHAR2(32);
    nl_bindcnt constant nt_assoc_small ('xml_gkregnl') := 3;
end;
I know this array hat just one element, but there will
be even more when I got this example case to work. As
I tried to compile this package, the compiler said:
13/16 PL/SQL: Declaration ignored
13/25 PLS-00566: type name "NT_ASSOC_SMALL" cannot be constrained
13/70 PLS-00320: the declaration of the type of this expression is
incomplete or malformed
O.K. then: Does anybody know the "wellformed" declaration
for this kind of varray?
Thanx in advance,
Martin.

That's not a VARRAY declaration, it's a PL/SQL table / associative array.
There is no syntax to declare the contents of an associative array in-line.
They can either be assigned to directly or populated by BULK COLLECT (except for associative arrays indexed by VARCHAR2). Perhaps you could assign the return value of a function?

How to declare variable in table valued function

hello.
i have the following code to define a inline table valued function
but the use of cmn.ReshteId('Lf_WL') as a function in where clause is not good performance.
Alter function lf.fn_WholeLifeBn_GetForm(@ViewKind tinyint, @CurrentLocation int) returns table
as
return
select B.*
from lf.fn_LifeBN_GetForm(@ViewKind, @CurrentLocation) B
where Reshte = cmn.ReshteId('Lf_WL')
for better performance following code is good:
declare @Reshte smallint
set @Reshte = cmn.ReshteId('Lf_TS')
select B.*
from lf.fn_LifeBN_GetForm(@ViewKind, @CurrentLocation) B
where Reshte = @Reshte
but can not use it as the first code block in inline function.
please help for define a good function.

What do you think about Multi-Statement Table-Valued UDFs?
create function Func(@Var int)
returns @T table(ColName int)
as
begin
insert into @T(ColName) values (@Var)
return
end
select * from Func(10)
select * from Func(20)
---or
alter function Func()
returns @T table(ColName int)
as
begin
declare @Var int
set @Var = 10
insert into @T(ColName) values (@Var)
return
end
select * from Func()

Declaring a variable in a function: either the function or the eventListener I'm using doesn't work

Can anyone help me with this?
I have a set of Cue Points in an FLV I'm playing. It's an interactive quiz, so the idea is that flash will change a variable, theAnswer, to a different letter depending on which question it is. The answer to question 1 is B, question 2 is D, etc.
Either the cue point event listener isn't working, or else it is working and Flash isn't declaring the variables. Can someone help?
The error message I get is:
1120: Access of undefined property theAnswer.
I literally can't find a single problem with my code. I have an almost identical Event Listener further down which works.
var theAnswer;
vid.addEventListener(MetadataEvent.CUE_POINT, cueAnswers);
function cueAnswers(e:MetadataEvent):void{
var cuePointNames = e.info.name;
if (cuePointNames =="start")
theAnswer = "C";
else if (cuePointNames =="q2")
theAnswer = "A";
else if (cuePointNames =="q3")
theAnswer = "C";
else if (cuePointNames =="q4")
theAnswer = "A";
else if (cuePointNames =="q5")
theAnswer = "D";
else if (cuePointNames =="q6")
theAnswer = "C";
else if (cuePointNames =="q7")
theAnswer = "A";
else if (cuePointNames =="q8")
theAnswer = "D";
else if (cuePointNames =="q9")
theAnswer ="B"
else if (cuePointNames =="q10")
theAnswer ="B";
The function is called by this later:
function nkAinfo(e:MouseEvent):void {
if (theAnswer=="C")
trace("You clicked right");
else
trace("You clicked wrong");
What's going on? Is the function not being called or are my variable declarations wrong?

Probably not the answer to your question, but it could help anyways....
First there is another command that, to me at least, is much easier to read that a bunch of nested if/if elses. And that is the switch.
switch (e.info.name){
case "start":
theAnswer="C";
break;
case "q2":
theAnswer="A"
break;
//and so on
To me that is easier to maintain and read. But I don't think that is really what you need here. So just file that one away for the future.
In this case, what I think you need is an array.
var currentAnswer:String;
var correctAnswers:Array=new Array();
correctAnswers["start"]="C"
correctAnswers["q2"]="A"
// and so on.
Then your cuepoint handler function becomes something like this:
function cueAnswers(e:MetadataEvent):void{
     currentAnswer=correctAnswers[e.info.name];
And I'm a little confused by your mouse click handler. It would seem to suggest that the answer is always "C"? But I"m guessing that it is supposed to compare what the user clicked on to what the cuePoint has told it is the correct answer? Well if that is the case then it would probably look something like:
function nkAinfo(e:MouseEvent):void {
if(e.currentTarget.clickedProperty==currentAnswer){
     trace("Correct");
} else {
     trace("Incorrect");
With the way you are currently doing this I'm guessing that you have a bunch of repeated functions for each time there is a mouse click and that your code is a lot more complicated that it needs to be. And that somewhere hiding in all those lines there is an error that would be simple to fix if you could see it.
What the error is telling you is that somewhere your are trying to assign or retrieve theAnswer and it hasn't been defined yet.

Works with normal = declaration but not with .add() function call? Why?

I still have some problems in relation to my earlier post:
http://forum.java.sun.com/thread.jspa?threadID=5164571&tstart=0
Help is still warmely appreciated! Thanks already to you Franzis.
So I try to add several JScrollPanes into on Container variable allComponents.
I don't understand why in my program
allComponents = jspane;works but
allComponents.add(jspane);does not.
Same is true for Jpanel objects. In my program
allComponents = panel;works but
allComponents.add(panel);does not. Why is this?
Still I necessarily need to work with a add() function.
So where is the problem?

How to declare class for library like function

Hey guys I want to declare class Math and define method subtrction so that i can use it in other class like
package p1
public class Math
Math( ){}
int Subtration ( int a, int b)
return (a-b)
package p2
import p1.*;
Public Class Test
Test()
int somenumber=Math.Subtration(3,4);
For some reason I cannot see any methods inside Math class. when i type
somenumber = Math. it show me only one option and that is 'class' instead of mathods inside Math. any thoughts?
thx

Yes I am aware of Math class in java. The question is
how do i declare a class and call it's method in some
other class with out declaring an object of that
class.
Like I can just call Math.sqrt(4) with out
specifically declaring Math as an object. I want to
declare my own class which has some methods I wish to
call in some other class.MyClass.someMethod(). Just make sure that the methos is actually declared static. I suggest looking up the static keyword to find out what it means.

[Bash] How to `declare` a global variable inside a function?

#!/bin/bash
# Not using declare -A, array will be treated as indexed array rather than an associative array
seta()
for ((n=0;n<$1;n++)); do
printf -v a_$n[k] %s k$n
printf -v a_$n[j] %s j$n
eval echo inside seta: a_$n[k] = \$\{a_$n\[k\]\}
done
seta 3
echo outside: a_0[k] = ${a_0[k]}
echo outside: a_0[j] = ${a_0[j]}
echo
# Use declare -A inside function, array will be undefined outside
setb()
for ((n=0;n<$1;n++)); do
declare -A b_$n # Note here
printf -v b_$n[k] %s k$n
printf -v b_$n[j] %s j$n
eval echo inside setb: b_$n[k] = \$\{b_$n\[k\]\}
done
setb 3
echo outside: b_0[k] = ${b_0[k]}
echo outside: b_0[j] = ${b_0[j]}
echo
# The bad solution, only works if we know beforehand how many c_? arrays will be assigned inside setc()
for ((n=0;n<3;n++)); do
declare -A c_$n
done
setc()
for ((n=0;n<$1;n++)); do
printf -v c_$n[k] %s k$n
printf -v c_$n[j] %s j$n
eval echo inside setc: c_$n[k] = \$\{c_$n\[k\]\}
done
setc 3
echo outside: c_0[k] = ${c_0[k]}
echo outside: c_0[j] = ${c_0[j]}
My original code does the declare -A as in setb(). I was surprised when I saw all blank output... Now the problem is illustrated clearly by the setb() example.
The setc() example works, but a bit ugly: look at the two 3's...
My ideal solution would be, something like `declare_global -A b_$n` in setb()
Any ideas?

with current bash versions, i don't think it is possible to declare global associative arrays in functions.
what you are after is the "-g" option of typeset which is available in zsh.
i think i read somewhere that something similar may be planned for bash 4.2.

Global declaration in function group.

I have a function group within which i have 6 function modules. I want to declare global data in the function group which can be used in all the function modules. Is it possible? If yes then please give me the details..
Thanks,
Abhishek

Each function module is nothing but INCLUDE program. So, if you see the list of includes, there will be a TOP include which is common and will be accessible to all other function modules.
You can declare variables there.

Supply function in webdynpro for abap

Hi ,
        I have tree structure as below.
1.      Node A
               1.a      Node B
                   1.a.i    Node C
        I have declared method 'Method_A' as supply function for Node A.similarly
        I have declared method 'Method_B' as supply function for Node B.similary
        I have declared method 'Method_C' as supply function for Node C.
        When I am executing in debugging mode both 'Method_A' and 'Method_B' is triggering for initial display of tree. Without expanding Node A ,we are already getting the Node B data and storing in corresponding nodes. This is becoming performance issue as I am hitting database in those 3 methods. My problem is without expanding why that 'Method_B' supply function is
triggering. Please let me know if you have any idea.
Thanks,
Suma

The supply function is always get triggered even if you do not expand the parent node in tree.
Reason: It fills the value to the child node based on parent's value.
To avoid this, you can set teh condition as follows:
In node B supply function, method_B:
check the instance of parent node A here, and if that is not initial, then only hit the database for filling node B.
In node C supply function, method_C:
Check the instance of parent node B here, and if that is not initial, then only hit the database for filling node C.
This is the only possible solution one can think of.
