Custom Forum - Form based on 2 tables
Hi,
I've build a forum containing the usual thread and message tables.
I now need to create an 'Add New Topic' form which pulls in thread.title and message.content. I tried creating a form based on a view but get the "cannot select ROWID from a join view without a key-preserved table (WWV-16016)" error.
Does anyone know how I can get around this or any method that allows the user to enter a title and message which writes to the Thread and Message tables?
Thanks.
Hello,
You said you're trying to create a form based on a view.
How do you want to insert data in a view ?
Try to build your form with the table used in the view.
Hope that will help

How to add a new row in Tabular Form based on a table
Hi
I have tabular form based on a table.
I want the table to have an empty row when there is no data
in the table so that I can enter data directly.
But right now whenever the page is launched, its showing a no data found message and I have to press the 'Add Row' button to enter data.
Can anyone help me out on this?
ThanksHi Leo
Your suggestion works fine in the APEX 2.1
But in 3.0.1 it gives this error :
Error in add row internal routine: ORA-01476: divisor is equal to zero
Error Unable to add rows.
I am not sure why this happens. -
Exception Handling for a Form Based on a Table
I created a form based on a table. If a user tries to enter a
record with key data that matches an existing record, Oracle
Portal creates a page and displays:
Error:
An unexpected error occurred: ORA-00001: unique constraint
(TIMETRACK.SYS_C007185) violated (WWV-16016)
How can I capture this exception so that I can display a
friendlier error message (via a JavaScript alert or other
means) instead of this page?
FranJames, I tried your suggestion as follows:
doInsert;--- This is the default handler
Exception
when DUP_VAL_ON_INDEX then
p_session.set_value(
p_block_name => "_block",
p_attribute_name => '_STATUS',
p_value => ' Time has already been entered for this project on
this date. Click the Back button to return to the MIM Time
Entry page. ');
Raise;
end;
It did nothing. All I got was the default message.
I then changed '_STATUS' to 'A_STATUS'. The resulting error
message was: "Error: (WWV-00000)"
ON A RELATED NOTE...
I discovered while testing this form on IE 5 on a Mac, that
additional error messages are generated. With IE 5 on WindowsNT
only a message regarding the unique constraint is produced. On
the Mac there is an additional message "No conversion performed
for type INTEGER, value is NsNu (WWC-49102)"
Anyone have any thoughts as to why the output of system
generated errors should differ between a PC and a Mac?

Open Form Based On A Table in same window
Hi All,
First to make things clearer I'll explain what I CAN do:
Create a page which queries a session variable at the start and then
depending on its value outputs different HTML, but always in the same
format and more importantly the same window, to keep the look and feel etc...
I have a link in a page which when clicked opens a form using wwa_app_module.link
so it auto queries the form. This works fine.
What I CAN NOT do is:
The form was created using the "form based on a table wizard" and always opens
in a new window.
Can I make the form open in the same window that contains my wwa_app_module.link?
Is this possible in a newer version that I have (I got Release 1)
Any Suggestions?
Cheers,
BarryFirstly thanks Rahul Dubey for responding.
What I mean by " contains my wwa_app_module.link? " :
I have a form which contains a link similar to the one below:
http://xxx.co.uk:8015/pls/pod130/PORTAL30.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=1389245486&p_arg_names=EMPNO&
p_arg_values=7654&p_arg_names=_empno_cond&p_arg_values=%3D%3E
When I click on this link it opens the form and runs a query automatically.
The problem is I want to click on the link and have the form appear in the
same window, not a new one.
Cheers,

Dynamically change the value of a select list in form based on a table
Hi Friends,
I am using a form based on a table. I want to display two fields as select lists instead of text boxes and when a value
in a select list is selected, the corresponding values will be listed in the next select list. For example if department
value is selected in a select list the employees in that department will be listed in the employee select list. I saw a
metthod using ajax for achieving this in tabular form in Denes's sample application[Click Here| http://apex.oracle.com/pls/otn/f?p=31517:176:462842537250908::NO] .
Is there any way to achieve the same for a form based on a table,
Thanks,
TjHi Andy,
Could you tell me how I could use your example with multiple Application Items?
My page has 3 cascading select lists. The second is dependent on the first and the third is dependent on both the first and second. I thought I would just need to add the second application item as a get, but not sure what the syntax would be. I have troubleshooted to the point where my select list refreshes when I have one in the javascript...just not sure how to add the additional one?
Here's what I have (I have been referencing your 'Get Employees' page)
My Page Items:
P0_VENDOR_ID
P0_VENDOR_SITE_ID
P0_INVENTORY_ITEM_ID
My Application Items:
F_VDR_ID
F_VDR_SITE_ID
My query in the application process has both F_VDR_SITE_ID and F_VDR_ID in it.
My javascript function...this worked OK until I added the additional get.add('F_VDR_SITE_ID')
function getItems(filter, listName)
var xml = null;
var list = document.getElementById(listName);
var listvalue = list.value;
var get = new htmldb_Get(null,$v('pFlowId'), 'APPLICATION_PROCESS=Set_Items',4);
get.add('F_VDR_ID', filter.value);
get.add('F_VDR_SITE_ID', filter.value);
ret = get.get('XML');
if(ret)
var s = ret.getElementsByTagName("select");
if(s){
var o = ret.getElementsByTagName("option");
var oCount = o.length;
list.options.length = 0;
for(var i = 0; i < oCount; i++){
var l_Opt_Xml = o;
appendToSelect(list, l_Opt_Xml.getAttribute('value'), l_Opt_Xml.firstChild.nodeValue);
list.value = listvalue;
if (list.selectedIndex == -1)
list.selectedIndex = 0;
get = null;
Thanks,

Error creating form based on a table
This is wierd. I am running WebDB2.2
and up until now it has been no problem
creating forms from tables. But now in
this schema called SUMI I am unable to
create a form based on a table. I get
the error below. I have assigned SUMI
almost every possible permission
(DBA, WebDeveloper) so I
don't think it is a permissions issue.
Any ideas? Thanks in advance. Marvin.

Detail tabular form based on two tables
db11gxe , apex 4.0 , firefox 24 ,
hi all ,
i have a master detail form based on two tables , the detail form ofcourse based on one table , the problem is i want to include a column of another
table into the tabular form , so i have changed the query of the tabular form and included the column in it correctly ,
but the problem is about saving data , i can not save the data , i think
because the "mru" process is based on one table , that is because i face an error talking about "mru" process when i try to save the data ,
Error in mru internal routine: ORA-20001: no data found in tabular form Unable to process update.
so
what should i do to save the data ? should i create another "mru" process based on the other table or what ?
thanksAnything beyond "simple" requires that you do it yourself. I believe that what you want is "beyond simple"
As far as I know, you can only use the 'mru' on one table.
(I could be wrong)
If the conditions are right, you might be able to simplify things such that you can use the 'mru'.
ie CREATE VIEW on the two tables.
However, you need to understand how Oracle treats DML operations on views, what type of views can be updated, etc., etc.
If just creating the view doesn't work, creating an INSTEAD OF trigger on the view come to mind...
(lol) - at that point, you have already started down the 'dark path' of creating your own 'MRU'
personal note: triggers have a really baaaddd habit of hiding code from other developers. you are better off, in the long run, creating your own 'mru'..
ie a package with procedures to handle INSERT, UPDATE, and DELETES

Delete button on Form based on a table
I created a form based on a table. For the delete button, how can I make it ask before deleting the record? ie, when the user hits Delete, a question comes up that asks: Do you really want to delete this record? The user then hits Yes or No.
Please be specific, I'm new to Portal. Thanks for any help.1. Edit your Form and go to "Step 4 of 7, Formatting and Validation Options" section of the builder.
2. In the left frame, click on DELETE_TOP and/or DELETE_BOTTOM link.
3. In the right frame, you should see a section (i.e. "Javascript Event Handlers") where you can add your own javascript code. Click on the onClick event.
4. In the adjacent free-text field, add the following code:
javascript:if(confirm('Do you really want to delete this record?')){
null;
else
window.stop();
5. Click on OK to compile. That's it.
The window.stop() is needed to prevent the PL/SQL event handler (i.e. Update) from running. Without window.stop(), if the user presses Cancel, the form will perform an update anyway. You'll need to remember that the Form will by default perform the Javascript handlers first, then the PL/SQL handler. -
Need to build a form based on a table in a different schema
Hello all,
I am still new to APEX. I have been playing with it for a few days.
I have an APEX user 'demo' whose default schema is demo1.
But I need to create a form that can insert,update and delete based on table 'employee' in schema demo2.
Demo has all the rights on employee table in demo2. I also assigned the demo2 schema to demo user's workspace.
But when I am building the form, demo1 is th eparsing schema, but in table/view owner only demo1 is available. I don't see demo2 even though I assigned it to demo user's workspace.
Is it possible to build a form based on a table in a different schema? I tried creating a synonym, but it doesn't show up in the list of tables to select from.
I don't want to create views or anything because there are many tables in different schemas and it's not possible to go on creating views or such for each one.
I was able to access th etable in a report though by prefixing the table name with the schema name.
I would appreciate if someone could point me in the right direction.
Thanks!Varad,
Thank you for the explanation. So from what I understand, every time I create a form or report based on a table in a different schema, just change the parsing schema in application definition to the new one and create the form or report. So this way my forms and reports or whatever can be based on different tables in different schemas and they would run fine when deployed in a runtime environment (provided the appropriate privileges are there on the objects in context)?
I tried this and I was able to see the different schema and select the table and create the form. I haven't tested in runtime though.
Seems like a feasible option, need to test all scenarios though. If this is a feasible solution then there is no need to create synonyms or views (I am not talking about others' scenarios such as security etc) etc. Just appropriate privileges will do it.
Thanks Varad. Have you used this way of creating a form in your apps? I need to explore more to see if it breaks anything.
So, every time I need to select an object, say a table, in a different schema I need to temporarily change the parsing schema to that schema in the application definition? Is that a correct statement?
I will leave the thread open to see if anybody has any comments. -
Creating a search form based on a table.
Hello,
I'm currently trying to create a search form which performs a searchquery in values stored in a table in my database.
The table is filled peoples names,lastnames ,telephonenumbers and departments.
I can use the sample application to make a form based on the tableview but this returns a search textfield for every column in the table. I just want 1 searchfield/textfield to search on ALL columns at the same time and display the other fields as labels when returning the queryresults.
I tried searching the forums for an explanation on how to build said form and I checked Metalink but I have yet to find one. Anyone out there willing to help me out?
thanks in advance,
Melvin K.Why not use an instr with your data in a bind variable in your where clause for the select?? Page 1 sets an item called P2_Parameter with your value string slightly modified ('12345','345632','645534534','3434344')
Select a,b,c,d,e from some_table where INSTR(TO_CHAR(Lookup_column,'099999999'),:P2_Parameter)
Maybe that will work? Its off the top of my head, but should get you what you want.. (But to agree with one of the other posters, it is a BAD Design..) I would try like an interactive report to allow them to enter in acct #'s or whatever these are and let them access the rows that way..
Thank you,

How to create Form based on a table to display multiple record
Hello All,
Would somebody please tell me how to create a Form based on a single table ,
to view and insert multi record based on a single table.In other words I would like
to have a form as shown below ,where the users can Insert,update,delete,query and so on
Item Id PArt Number List Price
100 Item-1 $120.oo
200 Item-2 $150.00
300 Item-3 $50.00
I know I can do it as Single Record block using Tabular Format,but multiple record ?????
Thanks in Anticipation
BabuTry this method,
1. Creat a Master Detail Form (Custom Layout and not tabular)
and in the master block select one field.
2. In the HTML layout for master remove the reference for
that field(so that nothing will appear in the master block
of the form).
3. Before the update (in the Pl/SQL event handler select the 'Save' event and write the following code to avoid updating master block).
p_session.set_value(p_block_name => 'MASTER_BLOCK',
p_attribute_name => 'MASTER_ACTION',
p_value => 'None');
doSave;
For eg, let's say
Master is from 'Dept' table and Detail is from 'Emp' table(with join condition Dept.dept_id = Emp.dept_id). In the master remove everything except dept_id field and in the HTML layout for master remove the reference of the dept_id field(you cannot remove this field physically from the master layout). Now the form will look like multirow form rather than master detail form but only problem with this workaround is 'Detail Action' will be present in the detail block.
I hope this will help you.
Thanks

i am working on a form portlet based on a table. but i don't know how to add an ID coloumn to the table, an identifier for the row which will increment automaticly after each "insert" operation. Is this possible in Oracle portal, is there a datatype for this or soem kind of procedure to achieve this?
Can anyone help me on this issue?Small example:
CREATE SEQUENCE CLIENT_ID_SEQ
minvalue 0 start with 0
increment by 1
CREATE OR REPLACE TRIGGER CLIENTS_INS_TRG
BEFORE INSERT ON CLIENTS
FOR EACH ROW
BEGIN
SELECT client_id_seq.nextval INTO :new.id FROM dual;
END;

"Error: Document not found (WWC-46000)" with a form based on a table with blob item
Hi all,
I have to manage a table-based form. One of the fields of the table is BLOB and the corrisponding field of the form is HIDDEN.
When I push the INSERT button all works well but when I try to UPDATE I get "Error: Document not found. (WWC-46000)".
Have you some suggestions ?
Thanks,
Antonino
p.s. Oracle Portal 3.0.7.6.2 / NT
nullSorry, I think I did not explain well my problem.
Imagine this simple table:
key number;
description varchar2(50);
image blob;
I need to make a form that contains the corresponding "key" field and the "description" field but not the "image" one. I don't want to allow the end user to upload images!
When I insert a row the form works well and in the "image" field of the table an empty blob or null (now I don't remember) is stored: that's ok.
Now imagine I want to change the value of the "description" field. I submit a query for the right key, I type a new value for the description and finally I push UPDATE button but....an error occours.
I think this error is related with the Blob item of the table but I'm not sure.
Thanks again,
Antonino
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Dmitry Nonkin([email protected]):
Antonino,
If I understood the problem correctly:
The form's item type for BLOB column used to upload content cannot be hidden, that's why we have a special item type FileUpload(binary).

Apex form based on a table problems with ID column
Hi all,
Am going round and round in circles trying to get this to work and i'm not getting anywhere fast.
Trying to get a form to process an single row insert into a table.
Using Automatic Row Processing to insert, the pk column page item is hidden and protected.
I would like to put the source of the PK (hidden and protected) item to be the next value of my sequence:
CREATE SEQUENCE "MODULEFEEDBACKID_SEQ" MINVALUE 1 MAXVALUE 99999 INCREMENT BY 1 START WITH 196 NOCACHE NOORDER NOCYCLE
/But I can't manage to get it to work.. every time i try to submit the page it just says "ORA-01400: cannot insert NULL into ( table )"
Any ideas?!
Thanks in advance
Ashleighwhen you create the form you said that the sequence is associated to pk? i think not
then you can create a trigger that set the pk and in the mru return the value of the pk to the item associated with the pk
or recreate the form with wizard and set the sequence to the pk there -
URGENT: tabular form based on multiple tables
Hi All,
Its very urgent.......Can anybody tell me how to create a single tabular form to insert/update values from different tables.
I want to create a tabular form with 3 cols. 1st col should be from one table and another two cols from other table.Please help.........
Thank You
Regards,
Vinaya.You can use iframes in your page: (an iframe is a frame in your page. In this frame you can load another page) that way you can create three pages. The first page is the master page. The second and third page which also have tabular forms, are loaded as iframes in the first page
The iframe is created as follows on your first page:
1.create a html region
2 create the tabular form on the second and third page
3.reference the pages by entereing the following code in the regions that will be used for displaying them:
<iframe name="Your_region_name" id="123" frameborder = "0" src=the page referenced width="580 px" height="250px" scrolling = "auto"></iframe>
for example:
<iframe name="Charge_Region" id="123" frameborder = "0" src="f?p=&APP_ID.:14:&SESSION." width="580 px" height="250px" scrolling = "auto"></iframe>
