How to refresh the current page when retrieving data from database

hi all
in my application i want to navigate from different tables to different forms. The data in the table and in the forms is comming fromthe database. when i select a navigation link to database of a form it is connecting to database. so im manually refreshing the refresh button of I.E. which is big headache. so is there any way to refresh my current table or form dynamically at run time to retrieve from database
Thanks and regards

Hi,
Refreshing a connection to Database means re establishing your connection each time.It will be load for the DB to load the data every time generally not advisable to do.
Inorder to get the value from the DB you have load the driver and connect it using fireplug with the view for navigations.
for the same refer this link.

How to use the readLine() method when reading data from a URL?

Hello,
I have a URL which contains text input.
The only way to get the data from this URL is by opening a URL connection to it.
I would like to get the data from this URL but at the same time I would like to be able to use readLine() method of BufferedReader in order to read the data line by line.
My question is how do I combine between these two requirements in order to reed the data from the URL?
Roy

Hello Roy,
can you try out this code.
URL yahoo = new URL("http://www.yahoo.com/");
        URLConnection yc = yahoo.openConnection();
        BufferedReader in = new BufferedReader(
                                new InputStreamReader(
                                yc.getInputStream()));
        String inputLine;
        while ((inputLine = in.readLine()) != null)
            System.out.println(inputLine);
        in.close();

How to achieve SUBMIT for the current page when I click other tab?

Problem: How to achieve SUBMIT for the current page when I click other tab?
Description: I have a two-page application and each page associates with a tab. Say page1 associates tab1 and page2 associates tab2. In each page, I have a submit button, a after submit process associated to the submit button, and a tabular form. For page1, I fill out the fields and hit the button. The page1 will appear again and I can see the data I have insert. However, If I fill out the fields and click the tab2 (page 2) instead. when I come back to page1, the data I filled out are all gone. Is there any way in HTML DB to force the submit in the current page after you click other page. If use JavaScript, what is code looks like.
Appreciate your time and your answer.
Mike

Scott,
just for clarity, if I understood correctly what you said there are two possibilities:
1) keep the standard tab branch and give up the possibility of validating page items. Below you can find an example of such cases.
2) Replace the template substitution string and perform a "custom" button-like submit also adding a branch to the main page associated with the tab. Page items will be validated if the branch firing point is set after the validations.
I couldn't find an example of the latter, but I found easily an example of the former:
it's the "Report attributes", page 420 of app 4000.
If you enter 'aaa' in the "Number of rows" form field and then you press "apply changes", htmldb correctly displays an inline error message saying that the value must be numeric. On the contrary, if you click on the "Region Definition" tab, htmldb takes you to a page showing an oracle exception:
ORA-20001: Error in DML: p_rowid=4785927011172906402, p_alt_rowid=ID, p_rowid2=, p_alt_rowid2=. ORA-20001: Invalid numeric value aaa for column PLUG_QUERY_NUM_ROWS

How to get the current page URL

HI All
I am working in oracle apps 4.0
I have one page called history in that i have one page item called Application url. My application id is 122 but its a copy of application 106
How to get the current page url for the page item.
Any steps should be help ful
Thanks & Regards
Srikkanth.M

I'm not 100% clear on what the requirement is from the description, however it does sound like you are making things unnecessarily complicated.
If you want permanent/ID-independent links then use application and page aliases.
so here we used to display the url like this: <tt>{noformat}http://81.131.254.171:8080/apex/f?p=122{noformat}</tt>
Do you mean that the URL is displayed like that? If so that doesn't seem particularly helpful. How is anyone supposed to know what it is?
There are many ways to provide links in APEX—including lists and nav bars.
Where the link is to another resource located on the same server (such as another page in the same app, or a different app in the workspace), relative addressing can be used, making it unecessary to include scheme, domain and port information in the URL. For example, if the page to be linked to has a page alias <tt>ABOUT</tt> in an application with alias <tt>UNITY</tt>, and the apps share an authentication scheme/cookie to permit shared sessions, then the link URL is simply
f?p=UNITY:ABOUT:&APP_SESSION.

Hi,
Create a New window of Type 'Final Window' and Position it in the layout where u want to display the page numbers.
Now, create a text element in the window and create the text like below in the text element.
P1 Page &SFSY-PAGE& of &SFSY-FORMPAGES(3CZ)&
&SFSY-PAGE&                            - Current Page No.
&SFSY-FORMPAGES(3CZ)&         - Total No of Pages.
Note: dont forget to create the window type as 'Final Window', otherwise it will show ssome junk...
Hope it helps!!

How to retrieve data from database to the structure(complicated)

Hello everyone:
I want to retrieve data from database to the structure. but the structure defined like this below:
TOLERANZOB LIKE QAMV-TOLERANZOB
TOLERANZOB1 LIKE QAMV-TOLERANZOB
so how can I retrieve the data from the database ? make sure that the two fields contain data both.
Thanks in advance .
Regards
Nick

Hi Nick,
To retreive data for TOLERANZOB from QAMV,
If you know the key fields then use
SELECT SINGLE TOLERANZOB FROM QAMV INTO TOLERANZOB WHERE keyfields.
else, you can use
SELECT TOLERANZOB FROM QAMV UPTO ONE ROWS INTO TOLERANZOB WHERE....
Once you retreive the data using the select query, you can check if it is initial and if not move the data from TOLERANZOB to TOLERANZOB1.

What are the different ways of retrieving data from Oracle8i

What are the different ways of retrieving data from Oracle8i
into my HTML page ?
Is it JDBC and ODBC ?
Is there any other way ?
null

Methods I tried,
Applet using SQLJ/JDBC with JDBC drivers thin or Oci8,
Oracle Web Publishing Assistant,
HTP/HTF PL/SQL packages (if you have OAS 4.0)
Webserver Generator of Designer 2000 (if you have OAS 4.0)

EVDRE error "encountered problem when retrieving data from webserver"

Hi,
in a EVDRE we always get the error "encountered problem when retrieving data from webserver"
When analysing this further we noticed this is always generated when a base member is selected in the CV and the expansion on the row for this dimension is has one of the following expansion settings:
DEP
ALL
NOEXPAND
if we select SELF, the error disappears again and the EVDRE works fine again ... is this normal behavior?
there is no problem with application nor dimension.
D
solved it

Note that the keyword "ALL" does not include the member itself. This may cause some confusion, but as Harish implies, when you select a base member it finds no matches if your memberset is "ALL".
If you want to design a report to handle the user moving back and forth between base and non-base members in their CV, you either need to include SELF,ALL or SELF,DEP, or something similar....
OR you need to get a little fancier, and use EVPRO to look and see if the CV member is base -- evpro(app,member,"CALC") -- and then use some conditional logic in Excel to choose the correct expansion options. If Calc=N, use Self, otherwise use SELF,DEP or whatever you choose. This can be a bit tricky if you then want the user to be able to drill down in the report (especially if you want the workbook option to insert add'l rows on the expansion, rather than replace), but it's all possible.

Failed to retrieve data from database?

I am a new user
When I try to Preview a document I am prompted to enter in database information.
I have tried a few times to connect to my server and

When the OLE DB(ADO) page opens and asks for a server and a database, what is needed to stop the error from happening
If anyone has any information that would be great !

SQL State:42502 means an user authorization error. Check the user and it's access to the target database.

Problem refreshing the parent page when closing a modal window.

I have page that opens a modal window from a report link column. In the modal window I want to be able to make my changes and press an Apply button so that the modal window is closed and the parent page is refreshed to show the modified details in the report. In Firefox all works well but in IE I get the error message ‘Window.opener.location is null or not an object’ .
When I comment out window.opener.location.href=window.opener.location.href; the modal window closes without error but I want to refresh the parent page with changes made in the modal window.
I’m afraid my java script is very limited (the code is based on other peoples examples.)
Parent Page I call this function from a report link column to display a modal window. Sets the hidden SAVE_STATUS field in destination page to ‘N’
function modalWin(pshow)
var url;
url='f?p=&APP_ID.:'+pshow+':&SESSION.::::SAVE_STATUS:N';
if (window.showModalDialog) {
window.showModalDialog(url,"name","dialogWidth:650px;dialogHeight:700px"); }
else {
window.open(url,"name","height=700,width=650,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no ,modal=yes");
Destination page (modal window)
HTML Header.
The function closeWindow should refresh the parent page and close the modal window.
<base target=_self>
<script language="JavaScript" type="text/javascript">

</script>
Html Body attribute.
onLoad="closeWindow();"
P_UPDATE_DATE process called from the Apply changes button. Sets the SAVE_STATUS flag to ‘Y’ for the onload in the html body.
UPDATE event
SET event_date = :P5001_EVENT_DATE
WHERE contract_reference = :P330_EVD_CONTRACT
AND event_number = :P330_EVD_EVENT_NUMBER;
:SAVE_STATUS := 'Y';
Thanks in advance, I will have a look when back in the office on Monday.
Cheers Pete

Hi Chris,
Thanks for your help. I think I've sorted it using your first suggestion doing a refresh in the parent page, I just didn't know how at the time.
What I've got in the parent window after the call to the modal window is the reload window.location.reload(); and in the modal window I close it using window.close(); The down side being the refresh happens if I use my 'Apply changes' or 'Cancel' button but I can live with that for now.
It seems to work in IE and firefox but as I say most of what I'm doing is cobbling together using other peoples code without really understanding exactly what it does. Anyway thanks for your help, sound like I should look into JQUERY when I have time.
Thanks Pete
Parent window call to modal
