Populating 2d array
Hi All,
I'm trying to create a 2d array (10x10) with numbers from 1 to 100. At the moment I'm getting:
1 2 3 4 5 6 7 8 9 10
2 4 6 8 10 12 14 16 18 20
3 6 9 12 15 18 21 24 27 30
4 8 12 16 etc etc etc
What I want is:
1 2 3 4 5 6 7 8 9 10
11 12 13 14 15 16 17 18 19 20
21 22 23 24 25 26 27 28 29 30
31 32 33 34 35 36 37 38 39 40
41 42 43 44 45 46 47 48 49 50
51 52 53 54 55 etc etc etc
Can anyone help?
Thanks
well.. u didnt put the code but i can guess u did something like
for ( x = 1 ; x <= 10 ; x ++ ){
for ( y = 1 ; y <= 10 ; y++){
array[x][y] = x*y;
although u do not want to do that ;) u are doing row * column which gives u the multiplication table. try looking at it in smaller examples, say 3x3
1 2 3
4 5 6
7 8 9
notice as u travel accross left to right it increases by 1, and it increases by 3 downward. this behavior is consistant throughout the model. You can then simply add the two together column*1+ (row-1) * 3 and you have the value of any element in your array. The row is -1 because the first row has not yet reached the 3
This same principle from the smaller model can be used for your array

Can the Ring Properties/Edit Items/Labels be populated by array values?
Can the Ring Properties/Edit Items/Labels be populated by array values?
I'm trying to troubleshoot an existing LabView 7.0 application at our office (this is only the beginning of my nightmare) and I'm finding that there is an array being created out of discrete Elements, which is then being indexed using the Indexed Array function, using a Ring control as the Index input.
What I'm seeing is that whoever created this "Appication" seems to require that any new 'elements' that need to be added to the array need to added in AT LEAST two locations (add the element to the array and add a label on the Edit Items tab of the Ring control used to index the array) and there may be more locations I haven't found that also needs the same information. Since I can't see any way for the array and the ring control to 'compare' the text strings, I'm assuming the array is being indexed using the 'values' from the Edit Items tab. Ths would allow different text in the Ring dropdown than is actually contained in the text of the array.
This is contrary to most of the coding practices I've learned, so I'm wondering if I could use the text strings contained in the array itself to populate Item list in the Ring control?
Later I can create an 'entry form' that would allow new parts to be added by staff that doesn't require knowledge of LabView programming. (The "Users" should NEVER have to see the underlying block diagrams/code to add or edit parts ot test parameter values.)
ThanksIn 8.2 you can do this with a property node and the "Strings [ ] Property". It accepts an array of strings. Order of strings in array sets the order in the control. Should work in 7.0 as well.

Populating 2dimentional array from database table
Hi,
I have created two dimentional array
TYPE type_DIR IS TABLE OF site_direction.site_direction_id%TYPE INDEX BY BINARY_INTEGER;
TYPE type_DIR_LAN IS TABLE OF type_DIR INDEX BY BINARY_INTEGER;
var_DIR_LAN type_DIR_LAN;I have to populate data into this from a relational database tables "site_direction" and "site_lanes".
I'm using cursors like below.
CURSOR lane_numbers(c_site_id NUMBER, c_direction_id NUMBER) IS
SELECT site_lane_id
FROM site_lanes
JOIN report_parameters
ON site_lane_id = report_parameter_value
WHERE site_lanes.site_id = c_site_id
AND site_lanes.site_direction_id = c_direction_id
AND report_parameters.report_parameter_id = in_report_parameter_id
AND report_parameters.report_parameter_group = 'LANE'
AND report_parameters.report_parameter_name = 'LANE'
ORDER BY site_lane_id;
CURSOR direction_id(c_site_id NUMBER) IS
SELECT site_direction_id
FROM site_direction
JOIN sites
ON site_direction.site_id = c_site_id
JOIN report_parameters
ON site_direction.site_id = report_parameter_value
WHERE report_parameters.report_parameter_id = in_report_parameter_id
AND report_parameters.report_parameter_group = 'SITE'
AND report_parameters.report_parameter_name = 'SITE_ID'
ORDER BY site_direction_id; How could I do that?
Once I got populated two dimentional array with value, how could I return that values?
Do I need one more 2 dimentional array to return or could I use sys_refcursor?
Thanks.Return the values to what? Using what version of what software?
Ideally you are using those cursors, though I can't imagine why they are necessary, to BULK COLLECT into the array. If so then just pass the array as a parameter.
If passing back to an external program like JAVA or .NET then a REF CURSOR would be appropriate. -
Populating an array of objects with a loop. Noob PHP question.
Hey guys,
You are all such a great help! Here is another one for you, the simple code below should create an array of pizza objects (and it does) then display each object in order. However... for some reason each object in the array seems to inherit the properties of whatever the last object entered was.
This code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

</head>
<?php
class pizza{
public $price;
public $description;
public $name;
$menu2=fopen("pizzaMenu2.txt","r") or exit("System Error!");
$pizzas = array();
$arraypos=0;
//This loop does all of the READING and populating of variables
while(!feof($menu2))
//First get the array position
$arraypos = (int)fgets($menu2);
//Then Put in Title in title2 array
$pizzas[$arraypos2] = new pizza(0,0,0);
$pizzas[$arraypos2]->title = fgets($menu2);
$pizzas[$arraypos2]->description = fgets($menu2);
$pizzas[$arraypos2]->price = fgets($menu2);
} //End of reading loop
//begin writing data
$arraypos=1;
while ($arraypos <=3){
echo "the array is in position: ".$arraypos;
echo "<br />";
echo $pizzas[$arraypos2]->title;
echo "<br />";
echo $pizzas[$arraypos2]->description;
echo "<br />";
echo $pizzas[$arraypos2]->price;
echo "<br />";
$arraypos++;
}//end of writing data loop
fclose($menu2);
?>
<body>
</body>
</html>
returns this:
the array is in position: 1
Test Pizza Two
The same as one with an extra one, yum!
22.99
the array is in position: 2
Test Pizza Two
The same as one with an extra one, yum!
22.99
the array is in position: 3
Test Pizza Two
The same as one with an extra one, yum!
22.99
when it should return this:
the array is in position: 1
Test pizza One
Loaded with all that test pizza goodness! Lots and lots of ones 1111!
11.99
the array is in position: 2
Test Pizza Two
The same as one with an extra one, yum!
22.99
the array is in position: 3
Test Threeza!
Do you see what I did there? I added a three to pizza, hahaha, I am so punny.
33.33
using the following text file pizzaMenu2.txt:
1
Test pizza One
Loaded with all that test pizza goodness! Lots and lots of ones 1111!
11.99

Do you see what I did there? I added a three to pizza, hahaha, I am so punny.
33.33
2
Test Pizza Two
The same as one with an extra one, yum!
22.99
Now, I have done line by line testing and shown that the values are being entered into the proper objects in the proper array, but whatever goes in last overwrites all of the other objects, so in the end I have 3 objects in my array that are all the same. I am not sure what I am missing here.Christ-Guard wrote:

Populating 1D Array, Help with 1 Error
Hello,
I have just about finished a program that implements a .txt file containing a few records. The order is an int customerNumber, string firstName, string lastName, and float balance. The snipplet of code posted below is where I believe the problem lies, I just cant figure out where it is. Im not sure if my counter is not working correctly or what. The problem is that I'll input the customer number of the first record and it will output fine, but when I type in any other customer number, it returns null. It is supposed to return null if the customer number is not found in the array. The snipplet of code is posted below and if needed, i will post the entire program. Thanks for any help and feel free to ask questions:
import java.util.Scanner;
import java.io.*;
public class customerList {
private int count;
private customerRecord data[];
public customerList()
data=new customerRecord[100];
count=0;
public void getCustomerList(String fileName) throws IOException
while(count<100)
Scanner scan=new Scanner(new File("/Users/kd/Documents/workspace/Assignment1/src/records.txt"));
int customerNumber=scan.nextInt();
String firstName=scan.next();
String lastName=scan.next();
float balance=scan.nextFloat();
data[count]=new customerRecord(customerNumber, firstName, lastName, balance);
count++;
public customerRecord getCustomer(int customerNumber)
for(int i=0; i<data.length; i++)
if(data.getCustomerNumber()==customerNumber)
return data[i];
return null;ahh, i see....stupid mistake. would it still be 'legal' for me to do:
public void getCustomerList(String fileName) throws IOException
Scanner scan=new Scanner(new File("/Users/kevindoster/Documents/workspace/Assignment1/src/records.txt"));
while(count<100)
int customerNumber=scan.nextInt();
String firstName=scan.next();
String lastName=scan.next();
float balance=scan.nextFloat();
data[count]=new customerRecord(customerNumber, firstName, lastName, balance);
count++;
}or is there a problem with my limitations in the while loop -
Trouble creating and populating an array of objects.

Help populating an array of objects
New here, trying to figure this out.
I'm trying to create an array of objects, then populate the array defining fields. I stripped this down as far as i could to simplify the problem but I get the following error when I compile (i tweaked the carrot placment, formating issues i guess):
PointsTest.java:41: ']' expected
cubeArray[0] = new Point();
^
PointsTest.java:41: invalid method declaration; return type required
cubeArray[0] = new Point();
^
2 errors
My code:
class PointsTest{
public static void main(String[] args) {
//So far, this works.
//convert 3 numbers to point coordinates held in temp variables
float xT = (Float.valueOf(args[0])).floatValue();
float yT = (Float.valueOf(args[1])).floatValue();
float zT = (Float.valueOf(args[2])).floatValue();
Point point1 = new Point(xT, yT, zT);
point1.printXYZ();
class Point {
//A BASIC point class
//fields defined
float x, y, z;
//a constructor that sets initial XYZ values
Point(float startX, float startY, float startZ) {
x = startX;
y = startY;
z = startZ;
//a no argument constructor for defualt states
Point () {
x = 0;
y = 0;
z = 0;
//method
void printXYZ(){
System.out.println("coordinates: " + x + " " + y + " " + z);
class Cube{
Point cubeArray[] = new Point[9];
cubeArray[0] = new Point();
}I've looked for answers online without much luck, I'm not worried about using a loop to populate the array at the moment (you can do it one at a time, right?). Didn't see any obvious listings in the java tutorials about arrays of objects. Any help would be appreciated.You need to put operations inside of a method instead of just floating them around inside the top-level of your Cube class. The errors you are getting are related to the fact that only class data members or methods are supposed to be inside the top-level of a class definition.
Something like this should get you started:
class Cube{
private Point[] cubeArray;
public Cube(){
cubeArray = new Point[9];

Hi
I want to populate a byte array named data in such a way that its first element contains any digit between 1 and 9. Then from 2nd element till 8th element there would be a string and from 9th element till end (say 20th element), there would be another string. How can i populate my byte array in this way? One way to populate the array is to do it element by element but its bad when working with large strings.
Can anyone please help me???
ThanksNow if i again convert bytemsg to String using
toString function, and print it, it gives garbage
value, not "Testing". Please can u tell me why it is
happening??Calling toString on an array does not show the contents of the String. See the String class constructors instead.

Question on Populating an Array with Integers
Hi-
I want to populate an array I have created with integers that will come from user input.
I COULD have required the user to input one at a time, and hit enter after each one, assigning a new variable name to each successive int. That would defeat the purpose of an array, and is more code than needed to accomplish what I want to do.
Here's where I am stuck:
I have my own input reader class, no problem. I have my array declared and instantiated, no problem.
The int's will come in a string, and I can parse the string into ints. Now the rub- once the string is parsed into ints, how will Java know to sort the ints into my array?
For example, if I created an array of 6 ints, and ask the user for 6 ints, say, 123456. How will Java know to put the int 1 into array position 0, 2 into array position 1, etc etc?
Thanks
BradWill the user input int ALWAYS be a single digit (0-9) or can it be any int value? If it can be any value, you need to require the user to put some sort of delimiter between the values, like a space:
1 23 4 567 8
Read the input into a String and use StringTokenizer to get the String representing each int. Then convert using Integer.parseInt(). -
Error in a array populated using jsp in client-side in java-script
hii ,
I have this problem.
I have populated an array with records in jsp.The array is being populated correctly ..i hav check it .
Now I need to get back this array in client side in a java-script function.
I need this bcoz i need to check whether the value entered in a particular field in the form is there in the table before the form is submitted...hence the need of array.
Surprisingly in my java-script function i can get back the length of array,but as soon as i am writing something like arr[0] where arr is the name of array populated in server side using jsp,i am get scripting error.
i.e a code like
funtion partynamecheck()
var n=<%arr[0]%>
alert (n) ;
is giving scripting error.i.e showing error in page at the bottom left -side of browser.
but code like
funtion partynamecheck()
var n=<%arr.length%>
alert (n) ;
} is working fine.
Please help ..all wrk stuck.
ArnabHi,
i cann't help you with javascript, but the jsp-expression must have this syntax
var n=<%=arr[0]%>
Hope this help!

Using a local Array in a Business Rule
Newbie question here...
I am writing a business rule that applies a standard rate to a lot of different lines in a business rule. This rate only varies by year, so from a logical perspective I think of it as a 1 dimensional variable. However the rate is actually stored in my normal Essbase cube (8-dimensions) something like the following:
Dimension Dimension Member
Account: Rate
Dim2: No Dim2 Value (A dimension member called "No dim2 Value")
Dim3: No Dim 3 Value
Dim4: No Dim4 Value
Dim5: No Dim5 Value
Dim6: No Dim6 Value
Dim7: No Dim7 Value
Year: [varies by year]
So right now my formula to calculate things looks something like the following:
"Target Account 1" = "Driver Account 1" * Rate ->
"No Dim2 Value" ->
"No Dim3 Value" ->
"No Dim3 Value" ->
"No Dim5 Value" ->
"No Dim6 Value" ->
"No Dim7 Value"
But I have to do this for several "Target" and "Driver" Accounts in the rule, which means an ugly looking rule. What I would like to do is create a local array at the beginning of my business rule and populate it with the rate:
ARRAY _rate[Year]
and then set the value of the array equal to
Rate -> "No Dim2 Value" -> "No Dim3 Value" -> "No Dim3 Value" ->
"No Dim5 Value" -> "No Dim6 Value" -> "No Dim7 Value"
This will allow me to simplify my formula down to
"Target Account 1" = "Driver Account 1" * _rate
My first question is "can I do this?" I've been able to create an array and use it in the formula, but I can't figure out how to populate the values in the array from my main Essbase cube.
The second question is "does it make sense to do this?" In addition to making the code easier to read, my guess is that populating the array once and just using it within the scope of the rule would be a bit more efficient than referencing that big cross dim expression, but I really don't know.
Any advice anyone has would be appreciated.
Thanks
-GlennI am familiar with what you are trying to accomplish.
Having Essbase store a fixed rate over time to be used in calculations is possible. However formulas start to look complex depending on how many dimensions you have and what the desired outcome is.
There are alternate techniques to the one you mentioned.
You can create a new database for rates only and make it with fewer dimensions. Then use the @XREF function to retrieve it in your formulas.
If the rate doesn't change very often you can put the Rate inside of the formula as is.
For example Y2006_Rate = 5%.

Use of multi-dimensional arrays in forms - forms debugger crash
Hello All readers,
have an issue with use of multi-dimensional arrays in forms when debugging and/or calling another form post array-population.
USING VERSIONS: oracle forms 9.0.4, Jinitiator 1.3.1.17, oracle db 10.1
the following code snippet works from a when-button-pressed trigger when called without the debugger. when called with the debugger it crashes when any element of the multi-dimensional associative array is accessed/populated/read. In addition, if i populate the multi-dimensional array then call a form (a msgbox form to display the arrays content as a string) it crashes too.
declare
type datasource_rec is record (field varchar2(32), val varchar2(3999));
type datasource_arr is table of datasource_rec index by binary_integer;
type datasource_arr_arr is table of datasource_arr index by binary_integer;
l_arr datasource_arr_arr;
procedure poparr(i_arr out datasource_arr_arr) is
idx binary_integer := 1;
iidx binary_integer := 1;
begin
while (idx <= 10) loop
iidx := 1;
while (iidx <= 10) loop
i_arr(idx)(iidx).field := 'field'||to_char(iidx)||':'||to_char(idx); --# debugger crashes here with JVM aborting... message (which crashes forms builder too)
i_arr(idx)(iidx).val := 'test value';
iidx := iidx+1;
end loop;
idx := idx+1;
end loop;
end;
procedure printarr is
idx binary_integer := l_arr.first;
iidx binary_integer;
l_msg varchar2(4000);
l_response pls_integer;
begin
while (idx is NOT null) loop
iidx := l_arr(idx).first;
while (iidx is NOT null) loop
l_msg := l_msg||chr(10)||l_arr(iidx)(idx).field||' = '||l_arr(iidx)(idx).val;
iidx := l_arr(idx).next(iidx);
end loop;
idx := l_arr.next(idx);
end loop;
alerts.info('see console for full printout: '||chr(10)||l_msg);
--l_response := msgbox.show(l_msg); --calls another modal form to display a long message, which crashes the runtime with a java console message*
r$debug.print(l_msg);
end;
begin
poparr(l_arr);
printarr;
end;
The java console does not print anything useful when both forms builder and the runtime crash/hangs as a result of the debugger being attached (except displaying a "JVM aborting" message) but when the runtime alone crashes as a result of calling another form after popping the MD array it prints:
oracle.forms.net.ConnectionException: Forms session <28> aborted: unable to communicate with runtime process.

has anyone else encountered this problem and found a solution/workaround? is their some sort of memory limitation for forms-side handling of (multi-dimensional) arrays?+
many thanks

How to use Associative Array in sql query?
Hello,
I have a problem on using Associative Array variable on query; and my query is similar to the one below;
TYPE OTHERGENERICS IS TABLE OF NUMBER(10) INDEX BY BINARY_INTEGER;
othersGenerics OTHERGENERICS;
CURSOR cursor_othersGenerics IS
select master.GENERICCODEID
from ASMTRG_ARTICLEMASTER master
join ASMTRG_ARTICLEMAP map on MAP.ARTICLECODEID = MASTER.ID
group by MASTER.GENERICCODEID
minus
select FGG.GENERICCODEID
from asmtrg_icfocusgroup fg
join asmtrg_icfocusgrpchannel fgc on FGC.GROUPID = FG.ID and fgc.isactive=1
join asmtrg_icfocusgengroup fgg on FGG.GROUPID = FG.ID and FGg.ISACTIVE=1
where fgc.channelid=1 and fg.isactive = 1
group by FGG.GENERICCODEID;
BEGIN
OPEN cursor_othersGenerics;
FETCH cursor_othersGenerics BULK COLLECT INTO othersGenerics;
CLOSE cursor_othersGenerics;
SELECT icfrd.*,
CASE
WHEN EXISTS(select ta.genericcodeid from <???XXX???> ta where ta.genericcodeid = icfgrp.genericcodeid) THEN -1
ELSE icfrd.icfgroupid
END CLASSIFICATION
FROM ASMTRGVIW_ICFOCUSREPORTDATA icfrd
LEFT JOIN ASMTRG_ICFOCUSGROUP icfgrp on icfrd.ICFGROUPID = icfgrp.ID
WHERE (channelId IS NULL OR icfrd.CHANNELID = channelId)
AND (asmCodeId IS NULL OR icfrd.ASMCODEID = asmCodeId)
AND (yearId IS NULL OR icfrd.YEARID = yearId)
AND (monthId IS NULL OR icfrd.MONTHID = monthId)
END;
By the way this is a part of my function.
The "othersGenerics" is my associative array variable and <???XXX???> is the place where I need to use my "othersGenerics" array to check. So far I've tried
"select ta.genericcodeid from table(cast(otherGenerics as OTHERGENERICS)) ta where ta.genericcodeid = icfgrp.genericcodeid",
"select ta.genericcodeid from table(otherGenerics) ta where ta.genericcodeid = icfgrp.genericcodeid",
"select ta.genericcodeid from otherGenerics ta where ta.genericcodeid = icfgrp.genericcodeid"
and these are not working.
What is your suggestions?Your type will have to be created as an independent object in your schema. So CREATE TYPE cannot be in your function declaration, it has to be outside it. (And then the line inside your declaration that defines the type will have to be removed.)
But now I can see that you use this array as a kind of "temporary lookup table" - you populate the array and then use it for lookup in your select statement. An alternative way of doing this could be like this completely without arrays:
with othergenerics as (
select master.GENERICCODEID
from ASMTRG_ARTICLEMASTER master
join ASMTRG_ARTICLEMAP map on MAP.ARTICLECODEID = MASTER.ID
group by MASTER.GENERICCODEID
minus
select FGG.GENERICCODEID
from asmtrg_icfocusgroup fg
join asmtrg_icfocusgrpchannel fgc on FGC.GROUPID = FG.ID and fgc.isactive=1
join asmtrg_icfocusgengroup fgg on FGG.GROUPID = FG.ID and FGg.ISACTIVE=1
where fgc.channelid=1 and fg.isactive = 1
group by FGG.GENERICCODEID
SELECT icfrd.*,
CASE
WHEN EXISTS(select ta.genericcodeid from othergenerics ta where ta.genericcodeid = icfgrp.genericcodeid) THEN -1
ELSE icfrd.icfgroupid
END CLASSIFICATION
FROM ASMTRGVIW_ICFOCUSREPORTDATA icfrd
LEFT JOIN ASMTRG_ICFOCUSGROUP icfgrp on icfrd.ICFGROUPID = icfgrp.ID
WHERE (channelId IS NULL OR icfrd.CHANNELID = channelId)
AND (asmCodeId IS NULL OR icfrd.ASMCODEID = asmCodeId)
AND (yearId IS NULL OR icfrd.YEARID = yearId)
AND (monthId IS NULL OR icfrd.MONTHID = monthId)
...The with clause (subquery factoring) you can think of as a kind of temp table called othergenerics created "on-the-fly".
The optimizer may decide to actually create a temp table for you and use in the lookup, or it may decide to rewrite the query into suitable joins or nested loops or hashing - whatever the optimizer decides will be the optimal way of doing things :-)
So unless you use your array other places in your function, I would recommend dropping the array completely, skip populating an array, and instead use a with clause for your temporary lookup.
