Please help: How to pass variable from main select to subquery
I have a table with four columns (id, status, start_date and end_date) as follows. What I want is to get the difference between the statuses' start_date to find out how long it takes for the ID to change status. Basically getting the difference of the Start_dates of the statuses for the ID.
ID Status Start_date End_date
1 NEW 02-FEB-07 02-FEB-07
1 OLD 04-FEB-07 06-FEB-07
1 BAD 09-FEB-07 14-FEB-07
I had initially thought of doing this
SELECT ID, (SELECT Start_date from tbl where Status = 'OLD' and ID = 1) - (SELECT Start_date from tbl WHERE Status = 'NEW' and ID =1) from tbl where ID = 1
but that would not work since I have more than one id and implementing inside Java will be complicated. Please help me what I need to do .. Thank you
Or this:
SQL> CREATE TABLE t AS (SELECT 1 ID , 'NEW' status, '02-FEB-07' start_date, '02-FEB-07' end_date FROM DUAL
UNION ALL SELECT 1 ID , 'OLD' status, '04-FEB-07' start_date, '06-FEB-07' end_date FROM DUAL
UNION ALL SELECT 1 ID , 'BAD' status, '09-FEB-07' start_date, '14-FEB-07' end_date FROM DUAL
UNION ALL SELECT 2 ID , 'NEW' status, '02-FEB-07' start_date, '02-FEB-07' end_date FROM DUAL
UNION ALL SELECT 2 ID , 'BAD' status, '05-FEB-07' start_date, '10-FEB-07' end_date FROM DUAL
UNION ALL SELECT 2 ID , 'OLD' status, '07-FEB-07' start_date, '10-FEB-07' end_date FROM DUAL
Table created.
SQL> ALTER SESSION SET nls_date_format='DD-MON-RR'
Session altered.
SQL> SELECT ID,
status,
start_date,
TO_DATE (start_date)
- LAG (TO_DATE (start_date)) OVER (PARTITION BY ID ORDER BY TO_DATE
(start_date))

OBIEE 11g How to pass variable from one prompt to another prompt in dashboard page.
How to pass variable from one prompt to another prompt in dashboard page.
I have two prompt in dashboard page as below.
Reporttype
prompt: values(Accounting, Operational) Note: values stored as
presentation variable and they are not coming from table.
Date prompt values (Account_date, Operation_date)
Note:values are coming from dim_date table.
Now the task is When user select First
Prompt value “Accounting” Then in the
second prompt should display only Accounting_dates , if user select “operational”
and it should display only operation_dates in second prompt.
In order to solve this issue I made the
first prompt “Reporttype” values(Accounting, Operational) as presentation
values (custom specific values) and default presentation value is accounting.
In second prompt Date are coming from
dim_date table and I selected Sql results as shown below.
SELECT case when '@{Reporttype}'='Accounting'
then "Dates (Receipts)"."Acct Year"
else "Dates (Receipts)"."Ops
Year" End FROM "Receipts"
Issue: Presentation variable value is not
changing in sql when user select “operation” and second prompt always shows
acct year in second prompt.
For testing pupose I kept this presentation
variable in text object of dashboard and values are changing there, but not in
second prompt sql.
Please suggest the solution.You will want to use the MoveClipLoader class (using its loadClip() and addListener() methods) rather than loadMovie so that you can wait for the file to load before you try to access anything in it. You can create an empty movieclip to load the swf into, and in that way the loaded file can be targeted using the empty movieclip instance name.

Please help how to pass a JavaBean from servlet to jsp?
Hi there,
I have got a dispatch servlet and I want the dispatch servlet to get the data and store it in a JavaBean before dispatching to the appropriate JSP page. However, I don't know how to pass the javabean to the JSP when the servlet forward the request to the JSP. Is ServletContext.setAttribute() the only way to pass the javabean to the JSP page?
Thank you very much!
EdmundYou can use HttpServletRequest.setAttribute(String name, Object javabean) to set the javabean into the HTTP request that you are forwarding to the JSP.
In the JSP, you can access the Javabean using request.getAttribute(String name) and cast it to the right class. -
How to Pass Variables from One Application to Another Pop Up Window
Hi,
I am wondering if anyone on the list has tried calling up a
pop up manager, and have two other variables imported for secondary
usage. I have tried using [Bindable], but this does not seem to be
working, and I am still getting errors that tells me that the
variables are "not defined" when it gets passed to another
HTTPService. I tried embedding the Pop Up Manager in the same
application as the one that is supposed to "pass the variables,"
but it no longer acts as a pop up window.
Could anyone please tell me where I can find the answers for
this?
Thanks in advance.
Here is the code of what I have for my pop up manager:

I am trying to display some data on the Child window that
would need to take the data from the parent titleWindow, which
could be drop down menus, text labels or combo boxes. I would need
to use a HTTPService on the child dialog box to accomplish task I
think, but the problem is, how would I get the information from its
parent window? The example I have are all about how the text input
from the child window gets feed back to the parent.
Would I need to create a "reverse" declaration or something
so I can access the information from the parent in the child
window?
I hope this makes sense.
Thanks for your help.

How to pass data from main vi/exe (sender) to many vi/exe (receivers) with one receiver code/vi?
Hello all
I am tring to dev some data distribution system, where one vi gets data from hw to shared variable. Vi compiled to app "sender.exe" The others units (receivers) should receive that data from shared var and write it to different serial ports (configured by user in runtime via control). Number of actually working ports may vary.
Should (and can?) this "receivers" vi's be the one vi, compiled to app "receiver.exe" and executed many times with different settings (diff serial port number)? // I tried this, second+ execution of receiver.exe just makes existing window active instead of creating new process as it works with other languages.
Or should i build many different vi (receiver1, receiver2, ... with actually the same content) into different .exe to run them at the same time?
Or may be the best way to build multi-port receiver with ability to communicate with any number of serial ports? // i dont like this, no code reusage here ))
The question is complicated with possibility to work via network (one of the reasons to make different exe for receivers) and may be the shared vi namespace may not allow many receiver-side vi's to have the same name?
In short, it should work as SENDER.exe >> RECEIVER1.exe, 2, 3... i.e. "one to many".
Asking for a best solution advice.

To allow multiple instances of the same exe, read this.

How to pass variable from Java to ABAP in BSPs
Hello experts,
taking into account the two environments (browser and server) I need to pass information from Java to ABAP.
After seen this link: Re: View Refresh
I have tried the next:
HTMLB: <input type="hidden" name="myFlag" value="">
ABAP: DATA: lv_height TYPE STRING.
JAVA: var intXo = readCookie("XEix");
JAVA: if ( intXo == 900 )
JAVA: else if (intXo == 725 )
ABAP: lv_height = request->get_form_field( 'myFlag' ).
ABAP: IF lv_height EQ 'X'.
ABAP: TRAYTAREAS_P = 'TRUE'.
ABAP: ELSE.
ABAP: TRAYTAREAS_P = 'FALSE'.
ABAP: ENDIF.
"document.all.myFlag.value" gets the correct value according the condition, but the ABAP code does not recover this value (lv_height is always initial).
Can you help me with that? I'm not able to see where is the mistake...
Exist any alternative way to recover in ABAP an JavaScrip value?
thanks in advance.

but it doesn't work. Can you detect if there is any evident error there or the process is right? -

Edited by: user612347 on Mar 16, 2010 4:57 PMHi,
Sorry, it's unclear what you want to do.
Whenever you have a problem, it helps to be as specific as you can.
Post a little sampel data (CREATE TABLE and INSERT statements) and the results you want from that data. Since your problem involves parameters, give a couple of sets of parameters, and the results you want for each set, given the same data.
Are you saying that, after the user enters one set of parameters, you will need to run a variation of this query:
SELECT a.assembly_item_id, a.organization_id, a.bill_sequence_id, b.bom_item_type, b.bill_sequence_id, b.component_item_id
FROM bom_structures_b a, bom_components_b b
WHERE a.assembly_item_id = '303'
AND
a.organization_id = '207'
AND
b.bill_sequence_id = a.bill_sequence_id
AND
b.bom_item_type = '4';several times? What will be different each time? Will the hard-coded strings in the WHERE clause ('303', '207' and '4') be values from the earlier query?
Do you really want to run this query several times, or would you rather run one query, and have it produce results for all the relevant values? (That would probably be eaisest and less error-prone). When you post your desired results, post what you would most like to see. If something else is acceptable, describe it.
You can write SQL*Plus scripts to use parameters (substitution variables.
For example, you can write a query that says:
WHERE a.assembly_item_id = '&1'
AND a.organization_id = '&2'
AND b.bill_sequence_id = a.bill_sequence_id
AND b.bom_item_type = '&3';and call it like this
@Section_03A_bom_structures_b 303 207 4You can have a query output several such rows (for example:
@Section_03A_bom_structures_b 303 207 4
@Section_03A_bom_structures_b 304 298 3
@Section_03A_bom_structures_b 306 99 4), send all of that output to a SPOOL file, and then execute the SPOOL file. -
How to pass values from main window to pop-up window?
I want to pass a value from the main window (1st form) to pop-up window (2nd form). The first form is of name booking.jsp and 2nd form is of name Fund_booking.jsp. I am using window.showModalDialog to open the window. I think, I have written right code in main window to pass the value but even then I am not able to get it on pop-up window. I am not even able to display an alert on pop-up window saying "hi" by writing a function on save Button in pop-up window. The code is as follows:
On booking.jsp:
<script>
function popup()
var aForm;
aForm = D_requisition_id.options[D_requisition_id.selectedIndex].text;
\\Here I have captured value from a drop down box in my main window form and assigned it to the variable.
alert(aForm);
var myObject =new Object();
myObject.Brandcode = aForm;
alert(myObject.Brandcode);
window.showModalDialog("Fund_booking.jsp",myObject,"dialogHeight:400px;dialogWidth:420px;");
</script>
<button name="B_FundBooking" tabIndex=4 style='POSITION:absolute;LEFT:393;TOP:292;WIDTH:100;height:24;BACKGROUND-COLOR:buttonface' onClick ="popup()">Fund Booking</button>
On Fund_booking.jsp:

<button name="B_Save" tabIndex=1 style='POSITION:absolute;LEFT:255;TOP:315;WIDTH:75;height:24;BACKGROUND-COLOR:buttonface' onClick ="ValidateData()">Save</button>
I am using DIV instead of frames in my both forms. I just want to get that value in my pop-up window to write a query based on which data will get displayed in my table of pop-up window.
Plz help me to solve this problem.Well, this is actually a JavaScript question, not a Java question but I can give some hints.
When you do pop-up windows you need to put JavaScript in the html of the pop-up itself. Data can be passed by creating new fields in the window object, which the popup can access via the window.openner field.
So, before invoking the popup add any data to be passed to the window object, then the onLoad function in the popup grabs the data. -

How to pass control from main controller to sub controller?
Hi Experts,
I have created one controller named "available.do" by which I am calling a view "available.htm". On that view I am showing one Button which says Check Availability. On clicking of this button it shows another view "list.htm". But it is showing new view and old view on same page.
Second I want to add one button on second view "list.htm" which should perform some function. I don't know how I can achieve this functionality?
Someone has suggested me that for this I have to create sub controller...but i don't know much about it as I am new in BSP.
Kindly tell me and paste code so that I can solve my both problems.

I guess you might have below coding in DO_INIT method,

How to pass variable from link in email into HTML DB
On our helpdesk application, we want to send emails to impacted customers, and have them click on a link in the email (that contains their ticket number) to get to a response form in HTML DB without having to copy and paste or re-enter that ticket number. How would I do this? At this point I don't know if the email will come from Outlook or from HTML DB.
Also, I see that there is a version of HTML DB for Windows machines. Does it interface with MS Exchange?
Thank you.Hi,
I have a HR Incident Reporting HTMLDB application that sends details of assigned calls to the assignee's email account, detailing the issue and including a URL to the relevant page in the application.
When the user clicks on the URL (appears as a link in their email) they go straight into the relevant application page (via login screen).
We use lotus notes, but I see no reason Exchange would work in the same way.
Cheers,

Please Help - How Do I Rip From WMP Directly - Zen Micro
Is it possible to rip directly from wmp directly to the zen micro? If so, how? I've given up on Mediasource as it won't connect to Gracenote CDDB.. Many thanks in advance..
PeteI'm sure only MediaSource can do it.
You mentioned that CDDB wasn't working with MediaSource. Did you try the advice here in the Zen FAQ at Nomadness.net? -
Passing variables from php to flash and the opposite
Hi guys, im trying weeks now to solve this problem but nothing yet
If someone could just tell me how to pass variables from flash to php and the opposite i would be thankful!!! Please help!I have recently had to learn this, so this may not be the best way but it worked for me
I suggest looking at the code below stripping out everything you don't need (e.g. the databse stuff) and just get a simple string going back and forward
have a go and post any problems here and I'll try and help
in flash i have
private function getBalanceAndXP():void
var request:URLRequest = new URLRequest("utils.php");
request.method = URLRequestMethod.POST;
var variables:URLVariables = new URLVariables();
variables.func = "getBalance";
variables.fbid = userID;
request.data = variables;
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.addEventListener(Event.COMPLETE, onBalanceComplete);
loader.load(request);
private function onBalanceComplete(e:Event):void
var loader:URLLoader = e.target as URLLoader;
loader.removeEventListener(Event.COMPLETE, onBalanceComplete);
var variables:URLVariables = new URLVariables(loader.data);
_balance = parseInt(variables.balance); // class variable
_experience = parseInt(variables.experience); // class variable
public function setBalanceAndXP(balance:int, experience:int):void
_balance = balance;
_experience = experience;
var request:URLRequest = new URLRequest("utils.php");
request.method = URLRequestMethod.POST;
var variables:URLVariables = new URLVariables();
variables.func = "setBalance";
variables.fbid = userID;
variables.balance = _balance;
variables.experience = _experience;
request.data = variables;
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.load(request);
and then I have my php file
<?php
$func = $_POST["func"];
$fbid = $_POST["fbid"];
$balance = $_POST["balance"];
$experience = $_POST["experience"];
$numVariables = 0;
$link = mysql_connect("localhost","username","password");
mysql_select_db("databaseName");
if ($func == "getBalance")
getBalance($fbid);
else if ($func == "setBalance")
setBalance($fbid, $balance, $experience);
mysql_close($link);
function getBalance($fbid)
$query = "SELECT balance, experience FROM tableName WHERE fbid = '".$fbid."'";
$result = mysql_query($query);
$row = mysql_fetch_row($result);
writeVariable("balance", $row[0]);
writeVariable("experience", $row[1]);
function setBalance($fbid, $balance, $experience)
$query = "UPDATE tableName SET balance = ".$balance.", experience = ".$experience." WHERE fbid ='".$fbid."'";
mysql_query($query);
function writeVariable( $name, $value )
global $numVariables;
if ( $numVariables > 0 )
echo "&";
echo $name . "=" . urlencode($value);
$numVariables++;
?>
