How can i display 5,10,15... records @ a time from a table in a DB?

well, i have developed a JSP application that shows ALL the employees in a certain department... the problem is when the number of employees increase the jsp page bcomes very, VERY long...
how can i do this by showing at least 20 records at a time... also like other jsp pages that i see that they have page numbers in the page above to show the other records... like...
page 1 20 records...
page 2, another 20...
... so on and so forth...
please help...
:]

Don't loop through the whole result set at once, just show records 1 to n....where n is whatever value you think creates a nice sized page. If you cache the results you can then display n+1 to 2n when the user hits a "more" link at the bottom of the page...and so on.
btw...caching may not be the best way to store your data, depends on the size of the resultsset, you may want to re-run the query each time and/or optimise the query to only fetch back the n results you want each time.

Short answer, use the apex_util.string_to_table to convert to a table; then you can either iterate through the table to generate a string of names, or accomplish the same with a bulk operation.

Encapsulate all this within a pl/sql function.

create a stored procedure (f.e. in schema myschema create a stored proc named renderAsHTML)
code for the procedure :
PROCEDURE renderAsHTML(p_itemId varchar2,p_pageId varchar2,p_siteId varchar2) IS
    l_displayName portal.wwsbr_all_items.display_name%type;
    l_name         portal.wwsbr_all_items.name%type;
    l_publishDate varchar2(10);
    l_url varchar2(250);
BEGIN
     -- Looking for item datas
     select display_name, name,   to_char(publish_date,'dd/mm/yyyy')
     into l_displayName,l_name, l_publishDate
     from portal.wwsbr_all_items
     where id =p_itemId and language=portal.wwctx_api.get_nls_language;
     -- getting the URL og the item
     l_url := portal.wwpob_page_util.get_page_url(p_pageId, p_siteId);
     -- HTML rendering
htp.p('<.a href="'||l_url ||'/'|| l_name ||'">' || l_displayName ||'</.a><.br/>');
htp.p('Published on ' || l_publishDate ');
EXCEPTION
    WHEN others THEN
           htp.p('<.div>Somme error occured , code is ' || SQLCODE || '.</.div>');
END renderAsHTML;
please notice that I've added a dot in HTML tags to avoid this forum to interpret them
note : make sure that you granted "execute" for the public user on teh procedure you've just created.
go to item properties (navigator>shared objects>item types>modify the one you want
go to tab3 (procedures)
set the following options :
type : PL/SQL
call proc : myschema.renderAsHTML
link text : render as HTML
icon : keep blank
select the "display proc results with the item" option
pass the following parameters :
attribute1 : item ID as p_itemId
attribute1 : page ID as p_pageId
attribute1 : pagegroup as p_siteId
Now, in your custom search portlet, go to results rendering, remove all attributes and add the "associated function" attribute.
Now, all the HTML generated by the stored proc will be rendered instead of the item.

I have created a Midlet that shoud display a certain list which is from the remote database. The list comes from a JSP file in the server. When I use the browser I can see the list.
The problem comes when I have to take the same list and output it in my midlet file. Then finding the selected index of the selecte item of the same list and using it somewhere else.

How can I display more than one record with result set meta data?

Hi,

    while(rs.next()){

    ps.close();
    }catch(Exception e){

        "<td class=normalFont>"+result.get(1)+"</td>"+
        "</tr>";
    return data;
    } All the things are wroking but the problem is that ArrayList is displaying just one record whereas I have more than 20 records to display. I tried with loop like: i<result.size(); and result.get(i) then its throwing exception
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 I stuck here for the last more than 2 days. Please help me

System.out.println(list.get(0));
abc
System.out.println(list.get(1));

[abc, def, ghi]That list has 3 items. Each one is a String.
But here is what you appear to be doing:
select * from person
+-----+-------------+-------------+--------+
| id | first name | last name | height |
+-----+-------------+-------------+--------+
|   1 | Joe         | Smith       | 180    |
+-----+-------------+-------------+--------+
|   2 | Mary        | Jones       | 144    |
+-----+-------------+-------------+--------+
for each row in ResultSet {
for each column in ResultSet {
    list.add(that element);
// which becomes
list.add(1);
list.add("Joe");
list.add("Smith");
list.add(180);
list.add(2);
list.add("Mary");
list.add("Jones");
list.add(144);
System.out.println(list.get(0));
1
System.out.println(list.get(1));
Joe
System.out.printlN(list);
[1, Joe, Smith, 180, 2, Mary, Jones, 144]That list has 8 items. Some of them are Strings and some of them are Integers. I would assume that, for this sample case, you would want a list with 2 items, both of which are Person objects. However, it really isn't clear from your posts what you are trying to do or what difficulty you're having, so I'm just guessing.

How can I display my bookmarks onscreen at all times as in IE?

IE allow the bookmark list to be displayed at all times on the left side of the screen. I find this very handy as it eliminates the many additional clicks needed in FF to track down a desired bookmark.

You can open the bookmarks in the sidebar via View > Sidebar Bookmarks
Press F10 or press and hold the Alt key down to bring up the "Menu Bar" temporarily.
You can also find a toolbar button in the palette to open the bookmarks sidebar (star without the drop marker) and drag the button on a toolbar.
Open the Customize window via "View > Toolbars > Customize" or via "Firefox > Options > Toolbar Layout"

In Vista you can set the volume and mute setting for each application separately in the volume mixer.
You can click the Volume icon on the Windows Taskbar near the clock and click the Mixer link at the bottom to open the mixer.<br />
You can adjust the volume level for each application in that window.<br />
You will only see the Firefox program in the Mixer if you are on a website that plays sound.

How can i display recent update/delete/insert records in form

Hai !!!!
i am new for forms,.......any body tell me, how can i display recent no of records updated or no of records deleted or no of records are inserted in a form. these records count are display in display items....give me detail explination......
Subbu.....

the easiest way is copy and paste the oracle-forms example from the OU.
You need form-level-trigger ON-ERROR + ON-MESSAGE, POST-INSERT, POST-UPDATE, POST-DELETE, three global variables and a procedure:
ON-ERROR
handle_message( error_code, 'ERROR: ' || ERROR_TYPE || '-' || TO_CHAR(ERROR_CODE) ||': '|| ERROR_TEXT );
ON-MESSAGE
handle_message( message_code, MESSAGE_TYPE || '-' || TO_CHAR(MESSAGE_CODE) || ': ' || MESSAGE_TEXT );
PROCEDURE handle_message( message_number IN NUMBER, message_line IN VARCHAR2 ) IS
BEGIN

How can I display the rows into columns.

How can I display the rows into columns. I mean
Create table STYLE_M
(Master varchar2(10), child varchar2(10));
Insert itno style_m
('MASTER1','CHILD1');
Insert itno style_m
('MASTER2','CHILD1');
Insert itno style_m
('MASTER2','CHILD2');
Insert itno style_m
('MASTER3','CHILD1');
Insert itno style_m
('MASTER3','CHILD2');
Insert itno style_m
('MASTER3','CHILD3');
Note : The Master may have any number of childs.
I want to display like this..
Master child1, child2, child3, .......(dynamic)
MASTER1 CHILD1
MASTER2 CHILD1 CHILD2
MASTER3 CHILD1 CHILD2 CHILD3
Sorry for disturbing you. Please hlp me out if you have any slution.
Thanks alot.

Here's a straight SQL "non-dynamic" approach.
This would be used if you knew the amount of children.
SELECT
     master,
     MAX(DECODE(r, 1, child, NULL)) || ' ' || MAX(DECODE(r, 2, child, NULL)) || ' ' || MAX(DECODE(r, 3, child, NULL)) children
FROM
     SELECT
          master,
          child,
          ROW_NUMBER() OVER(PARTITION BY master ORDER BY child) r
     FROM
          style_m
GROUP BY
     master
MASTER     CHILDREN
MASTER1    CHILD1
MASTER2    CHILD1 CHILD2
MASTER3    CHILD1 CHILD2 CHILD3             Since you said that the number of children can vary, I incorporated the same logic into a dynamic query.
SET AUTOPRINT ON
VAR x REFCURSOR
DECLARE
        v_sql           VARCHAR2(1000) := 'SELECT master, ';
        v_group_by      VARCHAR2(200) := 'FROM (SELECT master, child, ROW_NUMBER() OVER(PARTITION BY master ORDER BY child) r FROM style_m) GROUP BY master';
        v_count         PLS_INTEGER;
BEGIN
        SELECT
                MAX(COUNT(*))
        INTO    v_count
        FROM
                style_m
        GROUP BY
                master;
        FOR i IN 1..v_count
        LOOP
                v_sql := v_sql || 'MAX(DECODE(r, ' || i || ', child, NULL))' || ' || '' '' || ';
        END LOOP;
                v_sql := RTRIM(v_sql, ' || '' '' ||') ||' children ' || v_group_by;
                OPEN :x FOR v_sql;
END;
PL/SQL procedure successfully completed.
MASTER     CHILDREN
MASTER1    CHILD1
MASTER2    CHILD1 CHILD2
MASTER3    CHILD1 CHILD2 CHILD3I'll point your other thread to this one.
