Concatenate multiple rows in a single column

Hi
I am using Web Intelligence v4.0x (i think) and I am hoping to get help.
My query (from Performance Management Module) has a field name called "Device Name" and it has two rows, server1 and server 2 (maximum of 33 servers)
I am trying to concatenate these values so that a blank cell in a report reads
"Devices are: server1, server2"
I am not able to concatenate server1 and server2 (i.e. get server1, server2) in the above statement. I've tried to use Previous(Self) and it does not work. I get output in two rows as
server1,
server2,
Any assistance or direction is appreciated.
Thanks - Kev

Hi Jothi,
The solution that helped me earlier
"VAR1 =Replace(ReportFilter([Customer]);";";",")"
worked for one Customer ID that had two (or more) invoice# related to that Customer ID.
If there is more than one customer ID fetched by the query, the above solution merges all the related invoice# in that variable and does not merge invoice# per Customer ID.
E.g.
Customer ID     Invoice ID
0001               P100
0001               P101
0002               P150
0002               P151
Desired Output
Customer ID     Invoice ID
0001               P100, P101
0002               P150, P151
Actual Output: The query merges as:
Customer ID     Invoice ID
0001               P100, P101, P150, P151
0002               P100, P101, P150, P151
and so on till the last customer ID is fetched.
Is it possible to tweak the query to obtain the Desired Output? Your help is appreciated.
Thanks - Kavan

Concatenate multiple row values into single column value

Hello,
Can anyone please refresh my memory on how to concatenate multiple row values into a single column value.
In the following query, I will get multiple denial reasons per application and I would rather return all denial reasons on one line.

Create a view to shows data from multiple rows in a single column

Hi all - this is probably posted in the wrong forum but I couldn't find which was the correct one.
I am almost a complete novice at sql but I have a need to create a view which can be developed at 10g (which runs efficiently as the volumes are likely to be high) which will do the following.
Original table with columns Parent_code, Child_code
Parent_Code Child_Code
1000 2000
1000 3000
1000 4000
2000 3000
2000 5000
(note Parents can have multiple children and a child can have multiple parents!)
What I need to end up with in my view is the following
Child_Code Parent_List
2000 '1000 (3)'
3000 '1000 (3), 2000 (2)'
4000 '1000 (3)'
5000 '2000 (2)'
Note the number in parantheses is the number of children that the parent has - ie in the original table parent 1000 has 3 rows (one for each child)
This view is then to be used as a look up (on child code) for a business objects report.
Is there anyone who could PLEASE, PLEASE help me fairly quickly on this as I have very little time to find a solution?

Hi,
You can test these ones :
select child_code
     , ltrim(sys_connect_by_path(parent_info,', '), ', ') as parent_list
from (
select child_code
       , to_char(parent_code) ||
         ' (' ||
         count(*) over(partition by parent_code) ||
         ')' as parent_info
       , row_number() over(partition by child_code order by parent_code) rn
from your_table
where connect_by_isleaf = 1
connect by prior rn = rn-1
       and prior child_code = child_code
start with rn = 1
select child_code,
       rtrim(
         extract(
           xmlagg(xmlelement("e",parent_info||', ') order by parent_info)
         , '//text()'
       ) as parent_list
from (
select child_code,
         to_char(parent_code) ||
         ' (' ||
         count(*) over(partition by parent_code) ||
         ')' as parent_info
from your_table
group by child_code
;What you need is called "string aggregation".

Hi Justin,
Thanks for reply. The answer for your questions are:
1) No, sometimes could be 1 or 2 or 3 or....n
2) The true is that the result of the query have more columns. Here is the result of the query:
ID NAME VALUE SEC
     150     ALGOMAS     44 1
     150     AQWER     56456 1
     150     DFDSF     FG345143 1
     150     GFDGDF     5433 1
     150     TEST_123     HERRERA 1
     166     ALGOMAS     22 1
     166     AQWER     33 1
     166     DFDSF     44 1
     166     GFDGDF     55 1
     166     TEST_123     ANDREW 1
     243     ALGOMAS     1 1
     243     AQWER     2 1
     243     DFDSF     3 1
     243     GFDGDF     4 1
     243     TEST_123     WINDSOR 1
     505     ALGOMAS     VALOR DE CARAC 1
     505     AQWER     VALOR DE CARAC 1
     505     DFDSF     DDFDF 1
     505     GFDGDF     DFGG 1
     505     TEST_123     HERRERA 1
     505     TEST_123     CHARLES 2
     505     TEST_123     ANDREW 3
If you see the three last rows, it repeat the NAME and the ID, What I need is that three records combine in one only row.
This is really a subquery, only need the VALUE column for the "big query", but when i execute the big query, i got the ORA-01427 error: single-row subquery returns more than one row. I know that error comes out because the NAME = TEST_123 in the ID = 505 have more than one value, so, if there is any way to put that values in only one rows, it resolve my problems.

Let's say for example user have to the use the form to enter all 10 items or few like 5 on their stock form into 4 different textbox field each lines of your form, however these items go into a "Stock_table" under Single insert transaction query when submit button is pressed.
Please anyone help me out, on how to get this concept started.

Hello,
I have a way to do this, but it would take some hand coding on your part. If you feel comfortable hand writing php code and doing manual database calls, specificaly database INSERT calls you should be fine.
Create a custom form using the ADDT Custom Form Wizard that has all the rows and fields you need. This may take a bit if you are adding the ability for up to 20 rows, as per your diagram of the form area. The nice thing about using ADDT to create the form is that you can setup the form validation at the same time. Leave the last step in the Custom Form Wizard blank. You can add a custom database call here, but I would leave it blank.
Next, under ADDT's Forms Server Behaviors, select Custom Trigger. At the Basic tab, you enter your custom php code that will be executed. Here you are going to want to put your code that will check if a value has been entered in the form and then do a database INSERT operation on the Stock_table with that row. The advanced tab lets you set the order of operations and the name of the Custom Trigger. By default, it is set to AFTER. This means that the Custom Trigger will get executed AFTER the form data is processed by the Custom Form Transaction.
I usually just enter TEST into the "Basic" tab of the Custom Trigger. Then set my order of operations in the "Advanced" tab and close the Custom Trigger. Then I go to the code view for that page in Dreamweaver and find the Custom Trigger function and edit the code manually. It's much easier this way because the Custom Trigger wizard does not show you formatting on the code, and you don't have to keep opening the Wizard to edit and test your code.
Your going to have to have the Custom Trigger fuction do a test on the submitted form data. If data is present, then INSERT into database. Here's a basic example of what you need to do:
In your code view, the Custom Trigger will look something like this:
function Trigger_Custom(&$tNG) {
if($tNG->getColumnValue("Item_1")) {
$item1 = $tNG->getColumnValue("Item_1");
$textbox1_1 = $tNG->getColumnValue("Textbox_1");
$textbox1_2 = $tNG->getColumnValue("Textbox_2");
$textbox1_3 = $tNG->getColumnValue("Textbox_3");
$date1 = $tNG->getColumnValue("Textbox_3");
$queryAdd = "INSERT INTO Stock_table
(item, Qty_In, Qty_Out, Balance, Date) VALUES($item1, $textbox1_1, $textbox1_2, $textbox1_3, $date1)"
$result = mysql_query($queryAdd) or die(mysql_error());
This code checks to see if the form input field named Item_1 is set. If so, then get the rest of the values for the first item and insert them into the database. You would need to do this for each row in your form. So the if you let the customer add 20 rows, you would need to check 20 times to see if the data is there or write the code so that it stops once it encounters an empty Item field. To exit a Custom Trigger, you can return NULL; and it will jump out of the function. You can also throw custom error message out of triggers, but this post is already way to long to get into that.
$tNG->getColumnValue("Item_1") is used to retrieve the value that was set by the form input field named Item_1. This field is named by the Custom Form Wizard when you create your form. You can see what all the input filed names are by looking in the code view for something like:
// Add columns
$customTransaction->addColumn("Item_1", "STRING_TYPE", "POST", "Item_1");
There will be one for each field you created with the Custom Form Wizard.
Unfortunately, I don't have an easy way to do what you need. Maybe there is a way, but since none of the experts have responded, I thought I would point you in a direction. You should read all you can about Custom Triggers in the ADDT documentation/help pdf to give you more detailed information about how Custom Triggers work.
Hope this helps.

Multiple rows in a single row.

I want to know how can I store the values of multiple rowe in a single row.for an example..
machine name    manchine no frequency   month
Lathe                  MOO1          yearly         jan
Lathe                  MOO1          halfyearly   feb
Lathe                  MOO1         weekly       march and so on
I want this in a single row..
like                        jan       feb             march
Lathe       M001   yearly     halfyearly   weekly.
and in a single row I want this as per the month specified .
In my report I have 12 months distribution for each machine.

Taruna,
Just make sure understand the scenario correctly. Would you like to store the row in DB like this:
Lathe MOO1 yearly jan,feb,mar
then you expect to show in the report like this:
Lathe MOO1 yearly jan
Lathe MOO1 yearly feb
Lathe MOO1 yearly mar
Yes, you can do it this way, but somehow break the 1st principle of DB schema design - Atomic
Of course, you need to convert jan,feb,mar into list and display for each row.
string monthStr = "jan,feb,mar";
string [] months = monthStr.Split(",");
Kind Regards

Can I get multiple sums in a single column based on a "code" I place.

After importing a file of check/debit card activity from my bank, can I 'code' the line items based on tax categories ie Utilities, Medical expenses, Auto expenses, etc. and then get sums for each based on that code I placed in a single column? That would mean multiple sums in a single column based on the code used for each tax related expense. For instance, I would put UT in the column for utilities expenses and MED in the same column if it were a medical expense. I would then want the sum for all items in that column for each item code. Is this possible or do I need to use a different approach to get this information.

My guess is that the SUMIF function may be your friend.
It's well described in the *iWork Formulas and Functions User Guid*e which every user may download from the Help menu.

Inserting multiple rows using a single Insert statement without using dual

The below one works fine..
But is there any other change that can be done in the below one without using dual...
insert all
into ps_hd_samp (num1,num2) values (1,1)
into ps_hd_samp (num1,num2) values (2,2)
into ps_hd_samp (num1,num2) values (3,3)
select 1 from dual;

Select or deselect multiple rows with one single selection event

Does anyone know how to create a JTable which can select or deselect multiple rows with one single selection event in JTable. Fore example, if the table has
row1
row2
row3
row4
row5
row6
What I need is when user select row1 or row2, both row1 and row2 should be set to be selected. Then if user press CTRL and click one of row3 or row4, both of them should be selected including the previouse selected row1 and row2.
For deselection, if row1 and row2 are selected, when users deselect one of row1 or row2, both of them should be deselected.
Hopefully someone can give me a hint.

Here is a partial solution using a JList. Only one line gets highlighted when the user makes a selection in the list. But, two lines are returned. There is a blank line between every two lines.
     private void addLineToList() {
          String a = f_one.getText();
          String b = f_two.getText();
          if (a.length() == 0) {
               Utils.showInformationMessage("Item field is empty.");
               f_one.requestFocusInWindow();
               return;
          if (b.length() == 0) {
               Utils.showInformationMessage("Match field is empty.");
               f_two.requestFocusInWindow();
               return;
          model.addElement("item: " + a);
          model.addElement("match: " + b);
          model.addElement(" ");
          int size = model.getSize();
          pairList.setSelectedIndex(size - 3);
          f_one.setText("");
          f_two.setText("");
          f_one.requestFocusInWindow();
     private void editList() {
          if (pairList.getSelectedValue().toString().equalsIgnoreCase(" ")) {
               Toolkit.getDefaultToolkit().beep();
               f_one.requestFocusInWindow();
               return;
          if (!f_one.getText().equals("")) {
               int result = JOptionPane.showConfirmDialog(this,
               "The Item field contains text. Replace the text?",
               "Flash Card Activity", JOptionPane.YES_NO_OPTION,
               OptionPane.INFORMATION_MESSAGE);
               if (result == JOptionPane.NO_OPTION) return;
          if (!f_two.getText().equals("")) {
               int result = JOptionPane.showConfirmDialog(this,
               "The Match field contains text. Replace the text?",
               "Flash Card Activity", JOptionPane.YES_NO_OPTION,
               JOptionPane.INFORMATION_MESSAGE);
               if (result == JOptionPane.NO_OPTION) return;
          String item = "";
          String match = "";
          int index = pairList.getSelectedIndex();
          String choice = model.getElementAt(index).toString();
          if (choice.startsWith("item")) {
               item = choice;
               match = model.getElementAt(index + 1).toString();
               model.remove(index);
               model.remove(index);
               model.remove(index);
          else {
               item = model.getElementAt(index - 1).toString();
               match = choice;
               model.remove(index + 1);
               model.remove(index);
               model.remove(index - 1);
          int size = model.getSize();
          if (size > 2) {
               pairList.setSelectedIndex(size - 2);
          f_one.setText(item.substring(6));
          f_two.setText(match.substring(7));
          f_one.requestFocusInWindow();
     }

Concatenate multiple rows in a single column
