Tabular form, dynamic select list

Hi,
Direction as to how to tackle this problem politely requested please:
I have a "choices" table of three columns. Sample data shown below:
col1 col2 col3
a b c
a b d
a b e
f g h
f g i
The plan is to show these "choices" as a tabular form. With the example data shown above, this
would be shown as a two row grid, with the first row showing "a b" and at the end of the row there
would be a select box showing four possibilities: "c", "d", "e" or blank.
The "blank" meaning "no choice".
The second row would show "f g" and a select box for "h", "i" or "blank".
Neither the first two columns are editable by the end user - they just get to alter the third column.
How would I go about building this? Would it be a Report with a fancy piece of html for column three,
or perhaps a tabular form?
There can be more than two rows on the screen (of course) - beyond the sample data.
Any directional help appreciated; thanks in advance.

Hi Jure,
On reflection, that mention of the "stragg" function was very useful.
My first reply to you was a little uncharitable, for which I apologise.
Tom Kyte seems to have moved away from the "stragg" function and
has used "sys_connect_by_path" instead.
See http://tkyte.blogspot.com/2007/03/stringing-them-up.html
Once all that is in place (tested out via SQL Developer - not even a mention of Apex) it
seems relatively straightforward to integrate this into an Apex region.
Thanks again.

If you mean that you want to change the 'outcome' list of the human task, then this is not possible.

Creating a dynamic Selection List based on a View Object

Hello,
I'm new to JDeveloper and I would like to create a JSP Page with dynamic Selection List based on a runtime query or based on a view object (BC4J). The selection made by an user should serve another dynamic query with the necessary parameters that I built using createViewObjectFromQueryStmt(). By now I tried this using the InputSelectLOV from the Component Palette in JDeveloper. But without success. By the way: the selection list is not very large (5 values), so it's not necessary to have a form finding the desired value.
Maybe someone had experience about creating this already. Please give me a tip or a little example.
Thanks.

Tabular form with select list not updating

I have created a tabular form with a dynamic select list
select primary_key, column1,
htmldb_item.select_list_from_query(10,column2, 'select descr d, column_value r from lookup_table where column_value = '||column1) column2
from main_table
The select list appears to work correctly but the new value is not saved to the database. I assume this is because the tabular form element display as field for column2 is set to "standard report column" but when I select any of the "display as text" or "LOV" options either the current data is not displayed or errors are generated.
Any suggestions?
Thanks,
Bob

Hi Ian,
As you have seen, sorting on the project_manager_id column will sort by the id value rather than the textual value. This is, of course, because this is the value in the field.
I haven't tried this out, but one thing that may work is the fact that you don't have to include the ORDER BY fields within the SELECT statement. You could, for example, do:
select p.project_number, p.project_manager_id
from projects p, users u
where p.project_manager_id = u.id (+)
order by u.name
Obviously, you won't be able to do this in the existing statement as you would then be blocked from using column sorting. However, it implies that if you could construct the SQL statement dynamically, appending appropriate ORDER BY strings to the end of the base select statement, you could sort by anything you like. This does, of course, mean that you would have to create a mechanism to allow the user to select the sort order, generate the appropriate string and reconstruct the entire sql statement.
I had had a similar request quite a while ago. The underlying reason for that request turned out to be that the user just wanted to quickly locate records relating to one person. In the end, we agreed that a search filter was the best thing to do.

Dynamic select list: link to another page

Hi
Have following dynamic select list at the bottom in "product.php" page (www.dolls.com.sg)
<div id="selectcat">
<select name="Categories">
    <?php
do {
?>
    <option value="<?php echo $row_rsCategories['categoryName']?>"<?php if (!(strcmp($row_rsCategories['categoryName'], $row_rsCategories['categoryName']))) {echo "selected=\"selected\"";} ?>><?php echo $row_rsCategories['categoryName']?></option>
    <?php
} while ($row_rsCategories = mysql_fetch_assoc($rsCategories));
$rows = mysql_num_rows($rsCategories);
if($rows > 0) {
      mysql_data_seek($rsCategories, 0);
   $row_rsCategories = mysql_fetch_assoc($rsCategories);
?>
</select>
My target is, whenever a visitor clicks on a category in the pull down menu, he is forwarded to the respective "categories.php" page.
How can I do that?
Thanks
Helmut

Change your code to this:
<div id="selectcat">
<form method="get" action="categories.php">
<select name="Categories">
    <?php
do {
?>
    <option value="<?php echo $row_rsCategories['categoryName']?>">
    <?php echo $row_rsCategories['categoryName']?></option>
    <?php
} while ($row_rsCategories = mysql_fetch_assoc($rsCategories));
$rows = mysql_num_rows($rsCategories);
if($rows > 0) {
      mysql_data_seek($rsCategories, 0);
   $row_rsCategories = mysql_fetch_assoc($rsCategories);
?>
</select>
<input type="submit" value="View Dolls">
</form>
</div>
In categories.php, use $_GET['Categories'] to filter the recordset.

Creating dynamic select list

I have a dynamic select list populated by site names and URLs from a map; when a user clicks on an entry the site name and URL will fill two text boxes. There are also buttons to add, update, and delete entries. These buttons lead to actions within my JPF file.
          When I select an entry to delete, the script runs a delete SQL statement again my Ora db instance, then the page content is repopulated. I want to know how come when I do that I always get the sequence ID of the just deleted entry at the end of my select list.
          Here is a snippet of what I've got:
          JSP:
                    <netui:select
            dataSource="{actionForm.siteList[0]}"
            optionsDataSource="{actionForm.itemOptions}"
            size="4"
            tagId="siteList">
          <netui:textBox
            dataSource="{actionForm.title}"
            size="30" maxlength="200" tagId="title"/>
          <netui:textBox
            dataSource="{actionForm.url}"
            size="30" maxlength="200" tagId="url"/>
          <netui:hidden dataSource="{actionForm.key}"
            tagId="key"/>
          <script language="javascript">
            
          </script>
                              JPF:
                    Connection conn = null;
          query = "delete from stlnt_other_ref_sites " +
                  "where stlnt_ors_site_id = " + form.getKey();
          try {
            pstmt = conn.prepareStatement( query );
            pstmt.executeUpdate();
          } catch (SQLException ex) {
          try {
            Map map = new LinkedHashMap();
            while ( rs.next() )
              map.put(new Integer(rs.getInt(1)), rs.getString(2));
              jsArray += "siteArray[" + rs.getInt(1)
                + "]=new Array(\"" + rs.getString(2)
                + "\",\"" + rs.getString(3) + "\");";
              hasResults = true;
            options = map;
            getSession().setAttribute("jsArray",jsArray);
            getSession().setAttribute("hasResults",
              String.valueOf(hasResults));
          } catch (SQLException ex) {


OK I got it working... Mostly... I don't know if it was a combination of changes that made the difference, but I'll put down what I did. First, I switched my select object in the form bean into just a string type from a string array (it was allowing the selection of one entry anyways). Second, rather than just blanking out the options map, I also blanked out the select object [eg form.setSelect("")].
          Now when I select an entry and click delete, the resulting select list is short one visible element. However, you can still select the blank spot where that last entry used to be. However, this is not a huge issue for me now; I will investigate this at a later time.

Dynamic Select List - XML and umlaut

Hi, I've recently implement a dynamic select list as per [this thread|http://forums.oracle.com/forums/thread.jspa?threadID=327306], however it seems to break if I have any words containing an umlaut. I've tried setting the header on the Application Process to UTF-8 (OWA_UTIL.mime_header ('text/xml', FALSE, 'utf-8');) but it doesn't seem to make any difference. The word in particular giving me problems is Kühne - it's the only non english entry so far, but I would expect others in the future.
Does anyone have any ideas how to allow this character to be parsed correctly? Short of using replace to check for this and every other possible character I'm not sure what else to do.
Thanks

Hello
I would like to create a dynamic select list where you can start entering a name and select list reduces with each character entered.
E.g. A list of towns in the UK where you want to select London. This list is delay as normal and as start typing by the time you have entered “Lon” the list only has few names starting with “Lon”
I expect I need a JavaScript to active this?Not in APEX 4.x. Use a Text Field with autocomplete item.

Dynamic Select List in Reports

Hi,
I have come across solutions to implement dynamic Select Lists. But can the same be implemented in a report.
I have a report of 2 columns which are select lists. The Value of one depends of the other.
Can this be done?
Thanks in Advance

Hi Abdullah,
Thanks for the Tip. However, couple of queries.
1) The first modification involves changing the query to : select lov_pkg.savekey() , colA, colB, ... But the function savekey takes a value.
Ideally, I need this function to be called while loading and when the first select list is changed. How can this be done.
2) Also, To make this change in query, I had to use (Use Generic Column Names (parse query at runtime only)) option. Now my Add Row button doesnt work? Can you tell me how that can be customized.
Thanks,
Sunil

Dynamic select list crashes with php

HI All,
I can't seem to get a dynamic select list to work in
dreamweaver. It completly crashes everytime I try adding it to my
page. I found someone else in the forum who had the same problem
but no one ever responded. I've tried several things including
putting just the record set and dynamic select on it's own page
with no other code on it. It still crashes DW. I also tried coding
it myself by making a listmenu and modifying it so that the option
value equals a PHP echo of a value. It crashed there too. Does
anyone have a piece of code with a working dynamic select list that
uses a record set that I could look at? That way I can see where
I'm going wrong. All I'm trying to do is get a simple drop down
select list of employee names so someone can choose their name to
get commission. It's a one table, 2 fields (first & last name)
record set.
Using DW CS3, php & MySQL.,windows XP Pro
Any help would be really appreciated!

Dynamic select list with display,return val & join condition issue.

hello,
I am having a dynamic select list with display, return value
say for example my select statement is
select distinct dname d, deptno r
from dept dt
right join emp e on (e.deptno=dt.deptno)
where (condition)
when i tried this query for my select list, it is not working. It saying that
" LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query. "
I am not able to understand the problem. Can anyone help me out with this issue?
thanks.

Shouldn't your join have dept as the driving table?
select distinct dname d, deptno r
from dept dt
right join emp e on (dt.deptno = e.deptno)
where (condition)
Or using older Oracle standard join
select distinct dname d, deptno r
from dept dt, emp e
where (dt.deptno (+) = e.deptno) AND (OTHER WHERE condition)
OR
(Since a right join is just getting the values from the driving table that are NOT in the associated table)
select distinct dname d, deptno r
from dept dt
WHERE dt deptno NOT IN (SELECT deptno FROM emp) AND (OTHER where condition)

Default value dynamic select list

Hi everybody,
I have a question concerning dynamic select lists.
I have a report of a table that shows some records. Each record has different versions of data. So when you click on a record you get to another page where you get some information about this record and where you can select the version of this information (with the help of a select list).
The select list works fine and is defined dynamically as follows:
select distinct a.name display_value,
a.version_id return_value
from cn_pl_version a,
cn_pl_std_peplanung b
WHERE a.version_ID = b.version_id AND
b.pe_id = '&P6_HELP_PRODET.'
order by a.version_id desc
My problem is that when I click on a record I always get the report filled with the oldest version of the current record, so I always have to choose the newest version in the select list manually. I would prefer always to have the newest version in the report.
The query for the report is as follows:
select
(select sum(stunden) from cn_pl_std_peplanung t02
where abt_id = '10'
and t02.pe_id = t1.pe_id
and t02.version_id = t1.version_id
and t02.idee_id = t1.idee_id) stunden_ir,
(select name from cn_pl_version u01
where u01.version_id = t1.version_id) Version
from cn_pl_std_peplanung t1, cn_pl_projektelemente z1, cn_pl_version u1, cn_pl_projektidee s1
where t1.version_id = '&P6_VERSION_WAHL.'
and t1.pe_id = z1.pe_id
and z1.pe_id='&P6_HELP_PRODET.'
group by t1.pe_id, t1.version_id, t1.idee_id
'&P6_VERSION_WAHL.' is the item of the select list
'&P6_HELP_PRODET.' is the ID of the current record
I'm not sure if you understood my problem, my english isn't the best...
Thanks for any kind of help!!
Patrick

Hi Patrick,
what value does you select list show, when you branch to the page? Is it the correct one?
If not you should change your select list, that the correct version is selected as default. You can define a "default value" when you set the source of the element.
Otherwise you can maybe set up an example application at http://apex.oracle.com.

Dynamic select list with one static 'not_listed" option

Hi guys,
I want to create a dynamic select list with one static 'not_listed' option.
One possible alternative is to add the 'not_listed' record into database, but I really dont want to go that way unless there is no other way around.
Can anyone shed some lights on this?
Many thanks,
William

As usual : "It depends"...
If you have a foreign key defined on that field, Scott's reply won't work - unless you define '0 - Not listed' in the database. You can use selec 'not listed' d, to_number(null) r from dual though...
Another - more declarative way - is in the on 'Edit Page Item' page, in the 'List of Values' region set 'Display Null' to 'Yes' and 'Null Display Value' to ' - Not listed - '.

Dynamic Select List Allowed Values

Howdy Folks,
I am trying to allow end users to select their username. The usernames are generated from a rule library, and displayed in a select form element. I am doing this by having the allowedValues call the rule that generates the possible names directly. The rule returns a list of valid names. The problem I am currently having, is that if the page reloads or refreshes, then the allowedValues calls the rule again. Some of the username choices involve random numbers, so it is possible (and very likely), that separate calls to the rule will generate different potential values. So what is now happening, is that when a user selects the value, the page reloads, and the end user sees an error that looks like this:
( ) - Warning: Selected value for field 'Select a Valid User Name' does not match any of the allowed values.
The reason I am reloading the page, is that I am also trying to show the user what their email address will look like with the new value. So I have a different form element that is loading is value dynamically, and referencing the select form element. This mostly works, but the warning above is unacceptable.
Is there a way I can load the dynamically created list only once, the first time the form is viewed, and not load it again every time the page refreshes?
Another thing I tried to do (but didn't have luck with, so I sorta gave up on it) was to use the onChange of the select to change the value of email display field. This way the page never reloads and I don't have to deal with that issue. I'm thinking the onChange might actually work, but I would need to execute javascript or something, and not just use an express <set/> command to set the value of the field name that displays the email text.
Does anyone have advice on how to make the values only load once? Or how to change the value on the onChange event?
Thanks!
Jim

Mike,
Thanks for the feedback. I actually did try that eventually. I created a variable in the form, and initialized that variable to the list of possible values. Then I referenced the variable in the 'allowedValues' of the select form item. At that point in time I still had the select box set as an action, so it would reload the page, hoping to reload the value in the email display field. This still did not work. Each time the action fired off, the variable was re-initializing itself. I eventually tried to put in a check, so it would not re-initialize itself if it had already been initialized. That caused a syslog error.
I ended up solving the problem using javascript. I changed the field that reported the potential email address to an html element. Then for the html attribute I made a div with an ID. I then set a line of javascript into the onChange attribute of the select form element. This worked when ever the select form value changed. I then added the same line of javascript to the onLoad attribute of the jsp pages body element. This worked for loading the page.
This solved the problem of the page reloading and the select getting new values. That still happens if you actually reload the page, but all the form elements work without the reload now.
Thanks!
Jim
