HTMLDB_ITEM Package

Where can I get HTMLDB_ITEM packege for download and implement in our HTMLDB.
Thanks,
Ravi

hi ravi--
just to be very clear here, are you saying that you installed htmldb into your 9.2.0.4 instance using the oracle 10g companion cd. you're able to use html db but you're not seeing the htmldb_item package? if so, are you able to log into your database as someone like scott/tiger and describe htmldb_item?
thanks,
raj

HTMLDB_ITEM report with 'Drill Down'

I have created a report using the HTMLDB_ITEM Package and I would like to link to a form to add more detail. I have tried to create this using the tools but it assigns the value of the hyperlink to #column heading# which is not working. Am I missing something or is there another way of doing it?
Thanks

Issue with CSV export while using HTMLDB_ITEM.SELECT_LIST_FROM_LOV in SQL

Hi,
I have created a SQL report with HTMLDB_ITEM package. IN that report, I have generated a report column using SELECT_LIST_FROM_LOV, which can be used by the admin to update the column entry.
Here is the link:-
http://apex.oracle.com/pls/apex/f?p=50508:8:
The update is working fine, The issue is, if you download this report as a CSV, it will export all the values of the select list for that particular column. Is there any way to restrict the export to the single value of that column( or the current value in the database). Please help/ suggest.
thanks

HTMLDB_ITEM.TEXTAREA

Hi!
Is there "textarea" item in "htmldb_item" package?
I want to create it dynamically with PL/SQL and then process?
How can I do it? Thanks.

sure...there's an htmldb_item.textarea function that you can use. for some reason it's not shown in the online doc (and i've noted this), but it's doc'ed pretty well in the api spec...
function textarea (
-- Generates an HTML input type of text. Basically a single hight form field.
-- Arguments:
-- p_idx = The form element name, e.g. 1 equals f01, 2 equals f02, etc.
-- Typically the p_idx argument is constant for a given column.
-- p_value = Text displayed in HTML textarea.
-- p_rows = Height of the textarea (HTML rows attribute)
-- p_cols = Width of text displayed on screen (HTML cols attribute)
-- p_attributes = Extra HTML arguments you wish to add
-- p_item_id = Will set the ID of the item to this value (id="..."). Must be unique!
-- Try concatenating some string with rownum. Required for 508 compliance
-- p_item_label = Creates an invisible label for an item. Used for Section 508 Compliance. Class is hideMe508.
-- example(s):
-- select htmldb_item.textarea(1,ename) from emp
p_idx in number,
p_value in varchar2 default null,
p_rows in number default 40,
p_cols in number default 4,
p_attributes in varchar2 default null,
p_item_id in varchar2 default null,
p_item_label in varchar2 default null)
return varchar2

Column headings as HTMLDB_ITEMS

Is there a way to return column headings and HTMLDB_ITEMS? I am trying to place select lists into certain columns to be used as column filters to dynamicly build where clauses.

James,
I think it is possible, though I haven't tried something like this before. You would start with building your report region as a PL/SQL function returning SQL query, the query could look something like this:
return 'select ename, job, sal, comm, deptno from emp';
You would have to include some dynamic where clause of course. In the next step, you would go the reports attributes page and change the column headings type to be a PL/SQL function returning a colon-delimited list. And that function could look like this for the query above:
return 'Name:Job:Salary:Commission:'||htmldb_item.select_list_from_query(1,null,'select dname, deptno from dept')
Then you need to also have a submit button that actually submits your page and a branch that takes you back to your page. Or you could have the select list in your column headings do an auto-submit instead, this could be done when using the following function for the headings instead of the one shown above:
return 'Name:Job:Salary:Commission:'||htmldb_item.select_list_from_query(1,null,'select dname, deptno from dept','onChange="doSubmit(''f01'');"')
And you will also need a after submit process, that assigns the value selected to e.g. a page item that you then could use to build your dynamic SQL query. You can find information and examples for how to process items build using the htmldb_item package in the following How-To document. This document is about tabular forms, so it is different from what you are building, but it should provide you with the information needed.
http://www.oracle.com/technology/products/database/htmldb/howtos/tabular_form.html
I hope this gives you some ideas, let me know how it works out,

Creating Dynamic Radio Groups with HTMLDB_ITEM

Hi,
I'm using HTMLDB (1.5.1.00.12) and attempting to create a Dynamic Radiogroup using the HTMLDB_ITEM package in a PL/SQL region. (It's not known until runtime whether a radiogroup should appear on the page.) I normally call to HTMLDB_ITEM and htp.p the results to the screen.
If I was creating this radiogroup using a normal Page Item: Active/Inactive. I usually define a list of values as: STATIC:Active;A,Inactive;I
How can I do this with HTMLDB_ITEM package, and get both radiobuttons to appear on the same line next to each other? Unfortunately this function doesn't have a p_query I can pass values to. I'm sure I'm overlooking something obvious so I'm hoping some fresh perspective on this will help.
Thanks in advance!

Hi Patrick,
Thank you for your reply I have done this as follows.
function getTermdetailsQuerySuccsess(sender, args) {
  var listEnumerator = Termsitems.getEnumerator();
  // var datatable = document.getElementById("TermList");
  var i =0;
  while (listEnumerator.moveNext()) {
   i=i+1;
   var Question = listEnumerator.get_current().get_item('Title');
   var QuestionNumbers = listEnumerator.get_current().get_item('questionnumber');
   if (QuestionNumbers == 1) {
   $("#questiontable1 tbody").append("<tr>");
   $("#questiontable1 tbody").append("<td align='left'>"+ Question +" </td>");
   $("#questiontable1 tbody").append("<td align='Center'><input type='radio' name='question1Radio"+i+"' id='Question1Radio"+i+"'></td>");
   $("#questiontable1 tbody").append("<td align='Center'><input type='radio' name='question1Radio"+i+"' id='Question1Radio"+i+"'></td>");
   $("#questiontable1 tbody").append("<td align='Center'><input type='radio' name='question1Radio"+i+"' id='Question1Radio"+i+"'></td>");
   $("#questiontable1 tbody").append("<td align='Center'><input type='radio' name='question1Radio"+i+"' id='Question1Radio"+i+"'></td>");

Report with updateable checkbox

Here is what I want to do :
I have a report with a HTMLDB_ITEM.checkbox on a 'Y', 'N' field. I would like to be able to update that value by simply checking and unchecking my generated checkbox.
Example : select player_no, player_name, htmldb_item.checkbox(1,active,'N','Y') from players.
I would like to be able to uncheck the active checkbox and the field value for that player(using the player_no) would be updated to 'N' and vice versa when checking the box.
I had created a process that looped on my checkbox item like explained in the "how to", but only the check items were processed.
Then I tried adding the following to my select and looping on the second item, but both items do not follow each other. If I have 2 checkbox checked and 10 players, than the item 1(checkbox) has only 2 records compared to 10 for item 2(hidden player_no):
htmldb_item.checkbox(1,active,'N','Y')||htmldb_item.hidden(2,player_no)
Is my request feasible ?

Sorry, I used HTML tags to bold stuff, didn't realize that didn't work.
Sorry for the slow response, I have been swamped with work.
I am assuming everyone is using the htmldb_application.g_fxx(i) variables in PL/SQL processes when trying to process their checkboxes.
Here's an example that would be similar to Patrick's situation (above). This would be in the SQL for the report region:
htmldb_item.checkbox(1, player_no, decode(active, 'Y', 'CHECKED', null) || htmldb_item.hidden(2,player_no)
Let me explain why I'm doing this:
First: htmldb_item.checkbox(1, player_no, decode(active, 'Y', 'CHECKED', null) will create checkboxes. Rows with active = 'Y' would have a checked checkbox, but the value of the checkbox is the player_no. I would assume (and suggest) that player_no is a unique value for that record.
Second: htmldb_item.hidden(2,player_no) will be the item you wish to update. (I always make this the primary key or unique value, so I can update any data for that record, and it must be the same value as the checkbox value)
In the How To documents, they tell you to use this for processing checkboxes:
for i in 1..htmldb_application.g_f01.count
loop
--process here
end loop; where htmldb_application.g_f01 is your checkbox item.
I have noticed that it only counts the rows that have a checked checkbox. So if you have a report with 10 rows, and you've checked 2 checkboxes, the count for that item is only 2. Where as, the count for you hidden items is 10.
There are two ways I have made this process work, but here is probably the easiest way I would process all rows (rows with a checked checkbox and rows without the checkbox checked):
/*this will loop through every row of the report*/
for i in 1..htmldb_application.g_f02.count
loop
/*this will account for when they don't check any boxes*/
if htmldb_application.g_f01.count != 0
then
/*this will loop through the checked checkboxes*/
for k in 1..htmldb_application.g_f01.count
loop
/*this compares the values of player_no of the checkbox and hidden item*/
if htmldb_application.g_f01(k) = htmldb_application.g_f02(i)
then
--process where checkbox is checked
update xtable
set active = 'Y'
where player_no = htmldb_application.g_f02(i);
else
--process where checkbox is not checked
update xtable
set active = 'N'
where player_no = htmldb_application.g_f02(i);
end if;
end loop;
else
--same process where checkbox is not checked
update xtable
set active = 'N'
where player_no = htmldb_application.g_f02(i);
end if;
end loop;
Now I this is not exactly the same thing I have in my process, but this is extremely similar, so excuse any syntactical errors I have made.
Let me know if this helps. I realize when I post this, all the spacing I have to make the code easier to read is gone, so I would suggest spacing things in notepad for easier reading.
If you want to see how to use all the htmldb_item package items then you can be found them in the HTML DB documentation: https://cwisdb.cc.kuleuven.ac.be/ora10doc/appdev.101/b10992/mvl_api.htm#sthref1469

Questions on tabular layout

Hi,
I've got some doubt while developing forms application.
In tabular layout:
1) Can we set somewhere that enable user will always see an empty line as the last record in the block?
For example, we set 5 records in the block, when we hit the last row in the block (row 5), it will automatically
display an empty row below it. So when user move the mouse cursor into the empty line, it will be taken as trying to create
a new record.
2) could we change the item's property only pertaining to the current record, without affecting the other record?
For example, I have this data block on customer, which has id , name and address. From 5 records I showed, I would like to
disable column name and address when I navigate to record 2, but when I move record 3 it will be enabled again.
Your input is really appreciated. Thanks very much.
Wan

Thanks for the response Patrick. I guess I should have been more specific. What I do not understand is how to reference the values in the report if the select is for example: #1 select empno, ename, job, sal from scott.emp
If you are doing a manual tabular form, you use the PL/SQL variable HTMLDB_APPLICATION.G_F01 to HTMLDB_APPLICATION.G_F50 but in that case you would create the select differently, for example
#2 select htmldb_item.hidden(1, empno) empno,
htmldb_item.text(2, ename) ename,
htmldb_item.select_list_from_query(3,job,'select distinct job, job from emp') job,
htmldb_item.text(4,sal) sal from emp
HTML DB has allot of flexiblilty but not clear on how everything works yet.
If you have a one record form then you just reference the name of the item in PL/SQL as for example: :P2_EMP_NAME if P2_EMP_NAME is the item name in the form.
I guess if you create a report with type SQL Query (updateable report) then it must be a tabular form where the select has to be like in #2??? I tried to create like #1 and create a Multi Row Update process but that did not work. I get the message, Error in mru internal routine: ORA-20001: no data found in tabular form.
So I guess the question is: Is the only way to create a form in table format either by the Tabular Form wizard or using the HTMLDB_ITEM package?

How can I work with report columns in computation or validation?

Hi all,
I have an updateable report. Bevor submitting canges, I want to do computation or validation on one of the report columns. But a report column is not an item. Is there a possibility to work with report colums?
Thanks, Daniela

Hi Daniela,
Presumably, your tabular form has been created using the wizard?
If so, you might like to slightly change your SQL statement to allow you to access the "display only" columns in the collection.
When you have time, you should have a look at the HTMLDB_ITEM package api documentation as this explains how you can manually construct a tabular form. But for now, for the "display only" column, you need to do something like:
select
other fields,
HTMLDB_ITEM.DISPLAY_AND_SAVE(n,fieldname) columnheading
FROM table
where "n" is a column number - this will become G_F0n in the collection. You should ensure that you use a number that is not being used by an editable field - if you're not sure, do a View Source on a rendered page, and look for name="f01", name="f02" etc - these are the column numbers, pick one that isn't used for your new column.
The documentation says, for DISPLAY_AND_SAVE: "Use this function to display an item as text, but save its value to session state." so this sounds exactly what you need.
Regards
Andy

Page wwv_flow.accept not found

Hello,
I recently installed Oracle XE 11G and then Apex 4.1.1 on a Windows 7 Home Premium server. I went to create a workspace before I restored any data or apps. I created a new Workspace, and after inputting all the data and receiving the confirmation, I received a Page Not Found error with the following URL:
http://localhost:8080/apex/wwv_flow.accept
Any ideas as to what the problem is?

Scott,
Thanks. I tried this but it is not even displaying anything. All the info I find is about using htmldb_item package inside a SQL statement. I must mention that my region is a PL/SQL block (not a SQL query). I have a lot of custom code inside which I have my SQL statement too. Here's my code snippet:
if (substr(v_service, 0, l_index-1) is not null) then
select HTMLDB_ITEM.CHECKBOX(1,substr(v_service, 0, l_index-1)) "Z1",
service_name into v_temp, v_sname
from services
where service_id = v_value;
end if;
Thanks.

Wwv_flow.accept - page not found

I have a PL/SQL region whose source contains HTML source for displaying checkboxes, like this:
HTP.P('<input type=checkbox name="service_to_unsubscribe" value="' || v_name || '">'||v_sname);
This displays the checkboxes correctly.
Now, when I do not select any of them and press the Submit button, I get back to the same page with no changes (using a go to branch), which is fine. But if I select any of the checkboxes and then press the button, I get a 'Page cannot be found' error for the URL -- http://myserver/pls/htmldb/wwv_flow.accept
Can anyone help?
Thanks.

Insert multiple files from a single form

i'm trying to create a form to allow users to upload and attribute 10 image files at once to a single table. i followed the howto document:
http://www.oracle.com/technology/products/database/htmldb/howtos/tabular_form.html#MANUAL
and was able to create a form w/ten blank rows for insertion. however, the htmldb_item package that is used to write out the form controls does not provide an api to write out a file browse form control. is there another api i can use? if not is there a known kludge?

Scott,
i modified your suggestion and came up w/a more straight forward solution. here's the complete solution...
1. create a report based on a sql query:
select
x.IMG_SKEY
,x.IMG_TITLE_TX
,x.IMG_SRCH_KEYWORDS_TX
,x.file_browse
,x.CATEGORY_CD
from
(select
htmldb_item.hidden(1,IMG_SKEY) img_skey
,htmldb_item.text(2,IMG_TITLE_TX,12) img_title_tx
,htmldb_item.text(3,IMG_SRCH_KEYWORDS_TX,12) img_srch_keywords_tx
,'<input type="file" name="f50" size="30">' file_browse
,htmldb_item.select_list_from_query(4,null,'select category_name_tx , category_cd from image_categories order by 1',null,'NO',null,null,null,null,'NO') CATEGORY_CD
from "#OWNER#"."IMAGES"
where rownum < 0
union all
select
htmldb_item.hidden(1,null) img_skey
,htmldb_item.text(2,null,12) img_title_tx
,htmldb_item.text(3,null,12) img_srch_keywords_tx
,'<input type="file" name="f50" size="30">' file_browse
,htmldb_item.select_list_from_query(4,null,'select category_name_tx, category_cd code_value from image_categories order by 1',null,'NO',null,null,null,null,'NO') CATEGORY_CD
from dual
union all
select
htmldb_item.hidden(1,null) img_skey
,htmldb_item.text(2,null,12) img_title_tx
,htmldb_item.text(3,null,12) img_srch_keywords_tx
,'<input type="file" name="f50" size="30">' file_browse
,htmldb_item.select_list_from_query(4,null,'select category_name_tx, category_cd code_value from image_categories order by 1',null,'NO',null,null,null,null,'NO') CATEGORY_CD
from dual
note: union the null selects to get as many null rows as you want. i named the file control f50 to avoid conflicts. this control name is an array parameter in the wwv_flow.accept procedure that the form submits to. also, i unioned the null selects to the original table query which fetches no rows. this probably isn't necessary, but i left it in from the original example and had it select nothing because i wasn't sure if htmldb refrenced the column datatypes at all.
2. create a page item with the same name as your file control(f50) and change the display = never.
question: Scott, can you give me some insight into why you need this page item for the files to be uploaded. the files won't upload w/o the page item.
3. create a submit button which submits the page to itself. *make sure the button "database action = SQL INSERT action" or your files will not be uploaded to the wwv_flow_file_objects$ table
4. create a process to handle the processing of the form:
process point - after computations and validations
run process - once per page visit(default)
process:
declare
v_img_skey number;
begin
for i in 1..htmldb_application.g_f50.count
loop
if htmldb_application.g_f50(i) is not null then
begin
     select universal_seq.nextval
     into v_img_skey
     from dual;
insert into images(
img_skey
,img_title_tx
,img_srch_keywords_tx
,icat_category_Cd
,img_owner_name_tx
,img_last_updated_dt
values(
v_img_skey
,htmldb_application.g_f02(i)
,htmldb_application.g_f03(i)
,htmldb_application.g_f04(i)
,:APP_USER
,sysdate
end;
end if;
end loop;
end;
note: the value returned from the array htmldb_application.g_f50(i) will be the internal name of the file uploaded. i stripped down my code and removed the sections that move the file from flows_files.wwv_flow_file_objects$ into an image object and inserts it into my custom table, but anyone can use the technical notes on otn and metalink to figure it out.

Report mark rows and do summary

Hello all,
I have a report region, which shows many rows.
How can I mark several rows ,press a button and make a summary on one field within the marked rows?
Thanks for your help
Uta

I'm not sure what level of detail you are looking for, but the way you would usually do this is by:
1. Adding a column of checkboxes into your report, using the documented htmldb_item package.
2. Adding a button and a process conditional on this button. The process will iterate over your checkboxes and adds the relevant IDs to an APEX collection.
3. Use tour collection to generate your summary.
Handling checkboxes involves a bit of work, but it's well documented on the forum and I believe in a HOWTO (that I can't find the link to now.) Please feel free to come back with specific questions.

Delete chackbox for manually create report region

Hi guys,
First of all I want to say you're providing excellent support. I did research the topic but didn't come accross anything that worked (not to say I couldn't have missed something either). My challenge for the moment is that I've manually created a couple of multi-row report regions which appear on the same page & need to flag records for deletion. As I'm sure you know - I used the htmldb_item package to accomplish this - but the htmldb_item package doesn't support chekboxes. Is there a workaround?
Kind Regards,
Sabrina

Okay - here is one example of something I tried. You're right it's not necessarily a "bug", but as this note is made from the following how-to link "not supported".
http://www.oracle.com/technology/products/database/htmldb/howtos/tabular_form.html
Note: Checkbox, popup calendar, and popup key LOV
are not supported under updateable column attributes in report attributes section.
Example:
Select
x.address_line1,
x.address_line2,
x.town,
x.postal_code,
x.cntry_code
from
(Select
htmldb_item.text(1,address_line1,10) address_line1,
htmldb_item.text(2,address_line2,10) address_line2,
htmldb_item.text(3,town,10) town,
htmldb_item.text(4,postal_code,10)postal_code,
htmldb_item.text(4,cntry_code,10) cntry_code,
htmldb_item.checkbox(5,del_flag,decode( del_flag, 'Y', 'CHECKED', NULL )) del_flag

htmldb_item.text(1,null,10) address_line1,
htmldb_item.text(2,null,10) address_line2,
htmldb_item.text(3,null,10) town,
htmldb_item.text(4,null,10) postal_code,

Why I cannot process a disabled field when using htmldb_item

I have a report that has this in the select statement
case when c.sec_lic_status in (1,2,7,505,1002,1004,1005) then
htmldb_item.text(2,sum( distinct a.fee_variable),8,20)
else
htmldb_item.text(2,sum( distinct a.fee_variable),8,20,'disabled')
end "Quantity 1"
The above shows correctly. If there are 2 records one field is disable and the other is enabled.
I have a process that fires on submit - after Computations and Validations. But the records don't changed when updating the enabled one.
In debugging and writing to a file using the UTL_FILE package, I'm able to pinpoint that the disable fields are the problem.
Is there a trick on manually processing disabled fields?
I've found that when I uncheck the show box in the report, I cannot use the fields either. This is not a problem, just another comment.
My main problem is what do I have to do to manually process a disabled field.
Thanks for your help, comments, pointers, or anything that could help me or give me ideas.
juan

Juan - HTML items with the disabled attribute are not POSTed with the form so your after-submit processes never see them. Try 'readonly="readonly"' instead. Others may be able to suggest how to also give those cells a greyed-out appearance.
