Updating data throug a view in forms

Hi,
How is it possible to update data through a updateable view, when there is no rowids in a view? Can i define primary key some how to the form instead of rowid?
Regards Tarja

yes, you can choose one (or more) item then set the PRIMARY KEY property to yes.

FRM-40602: Cannot insert into or update data in a view

Hi all!
I have a form based on a view and I want to get rid off this message.
I set the properties blocks query only but it still doesn't work.
Does someone met with this situation?
Many thanks!

Hello
I've just been messing about with a similar problem. Basically, I have a view that involves a join across two tables, I have a data block in my form that's based on the view, and I've written an INSTEAD OF trigger to insert/update/delete from the two tables.
I was getting the error message 'Cannot insert or update data in a view', and it turned out that the error was happening because the join column between the two tables was the primary key on one of the tables, but the corresponding column on the join table had no unique key on it. This meant that Oracle couldn't establish a one-to-one relationship between rows in the view and rows in the underlying tables. The column on the join table was in fact unique on that table, and adding a unique constraint on that column in the database cured the problem.
Hope that's of use.

Update data from a view

Hi,
trying to update data from a view with:
- Company (table)

In a form, the user wants to update
e.g: both products.product_name and Company.company_name.
Is there a way to update a view records built on 2 tables ?
Any idea will be really appreciated

Want to update data in a view based on multiple tables

Hi
I am facing a problem i want to update data in tables using a view. As that view is based on multiple tables so i am unable to update data. i came to know we can update table from view only if view is based on single table. so if anyone knows any alternative please let me know.
Thanx
Devinder

Devinder,
The table can be updated through a view based on multiple tables, if and only if the table is a "key preserved" table. Rather than explaining myself, i avoided the burden of typing by finding the material in Oracle Docs and pasting it for you :-)
If you want a join view to be updatable, all of the following conditions must be
true:
1. The DML statement must affect only one table underlying the join.
2. For an INSERT statement, the view must not be created WITH CHECK
OPTION, and all columns into which values are inserted must come from a
key-preserved table. A key-preserved table in one for which every primary
key or unique key value in the base table is also unique in the join view.
3. For an UPDATE statement, all columns updated must be extracted from a
key-preserved table. If the view was created WITH CHECK OPTION, join
columns and columns taken from tables that are referenced more than once
in the view must be shielded from UPDATE.
4. For a DELETE statement, the join can have one and only one key-preserved
table. That table can appear more than once in the join, unless the view was
created WITH CHECK OPTION.

Setting and updating Date field in a jsp form

Hi:
I have a form (in jsp) where in I have a field for Date. The Date is entered in the form: 12/18/2002. I using beans to retrieve the form values and then pass to the program. THe date field is passed as String to the bean. The program changes the String to util date
(assignment ===> name of bean)
String strDate = assignment.getDueDate();
java.util.Date adate = null;
DateFormat fmt = DateFormat.getDateInstance(DateFormat.SHORT,Locale.US);
try {
adate = fmt.parse(strDate);
System.out.println("Util date in Bo: "+adate);
     catch (ParseException e)
          System.out.println(e);
and before inserting into database, it is changed from util.date to sql.date.
long time = adate.getTime();
java.sql.Date sqldate = new java.sql.Date(time);
Until now everythign is working fine. On my way back, when i retrieve the sql.date from the database, I change it to util date:
java.sql.Date sqlDate = rs.getDate("dueDate");
java.util.Date uDate = sqlDate;
and then covert this util date to String
String strDate = uDate.toString();
When I display this string date on my form... it is in the format
2002-12-18, although i have inserted it in 12/18/2002 format.
Can anyone help me since i want my date to appear on the form in the format I enter (12/18/2002) and not the 2002-12-18 format of database

Can not update data in table view

When i open a table from a connection in the connection navigator i can not alter the data in it... I can only add new rows. Is there a setting so i can alter the data?
My user has update rights because when i write my own update statement and execute it, it works fine.

I found the issue... You can do it in 10g but you have to define a PK on the table, otherwhise he does not know what row to update. When i added a PK i could edit the data in Jdev in data view.

View based form updation in 6i and 10g forms.

Hi All,
I am facing a strange problem.
I created a form based on a view, which is based on a single table. i made a copy of the form and converted it to 10g.
When running in 6i, i can update the data through forms. But in 10g, its showing FRM-40602: Cannot insert into or update data in a view.
Can anyone tell what is wrong?

hi Manu
How to insert new record or update existing record using a complex view?
to make dml against a complex view with instead of triggers a reality. There should be no need to write an on-update trigger in your form. Indeed, the reason for a view and instead-of-trigger on that view is so that you do not require additional coding in your form.
1) you need the instead-of-trigger on the view (confirm it is there)
2) you need to change the locking mode in the form for the block based on your view so that it uses the logical key for locking purposes. There is a lock mode setting somewhere in the block properties page, find it, understand the differences and pick the righ tone (I forget at this moment which on it is, try them all if necessary).
3) #2 will involve selecting those fields that map to the business identifier/primary key you want to you use for finding rows. You need to visit each field's property page and set the appropriate attribute to indicate that is is part of the key used to find rows. It is there on the properties page but not having forms available at the moment I cannot give you the property name. You will have to do a little exploring to find it.
If you do these things, the error should go away and the view become updatable via oracle forms without the need to write any on-update trigger.
Do some testing at the database level first. Make sure you can update the view directly via sqlplus first with the instead-of-trigger before you attempt it in the form. This will ensure that your issue is forms related and not database related. This is an important step because the database will return a similar error to what you have reported if the instead-of-trigger does not exist on the view.

Inserting/updating data in control block based on view

Hi!
I`ve created a block based on a view to display data.
I want this block to be insertable and updateable, that is I will use a on-insert/update trigger to call an insert/update procedure located in the database.
When trying to change/insert a value in the block, the error message "Error: Can not insert into or update data in a view" pops up. I`ve tried to get rid of this error, without success.
How can I make a data block based on a view insertable and updateable?
My guess is that this have something to do with locking the records(there is no rowid in the view)... but I'm not sure.
Pls advise!!

Morten
As well as on-update, on-insert, on-delete triggers you also need an on-lock,
(even though it might just contain null;) otherwise the form will try to lock the view and fail.
Actually your terminology is wrong, the block being based on a table or view is not a control block. A control block is not based on anything and has no default functionality for communicating with the database. If it was a control block, the on- triggers would not fire.

Prompts in one view to filter data in other view

All,
I have 2 views (Bar chart and pie chart) in the same report. I have to put a prompt on the report where user can select date.
Now I want to show this prompt only once on the report and use that prompt to update data in both views. Where shall I put this prompt and how can I use it to filter data in both views?
Requirement is to put the prompt on the report so that user can select date and time while viewing the report.
Thanks for your help.
Regards

Hello
You can put the prompt at the report level.
I would recommend using a surface prompt view at the top of the report.
An example is provided in the call center demo ( packaged with the product) -- Reassign cases report.

Updating data in adobe form

Hi All,
In my java webdynpro application, i want to show an adobe form and allow the user to update the data. Then, i want to store the form in binary in a db table.
The layout of my form is not fixed as a different form can be uploaded each time. So, all i have is the binary of the interactive form.
I have added the interactive form uielement in my view. I have bound the 'pdfsource' property to a context attribute that contains the binary of the interactive form to be shown. Also, i have chosen 'usepdf' in the mode.
Now, after the user updates the form, if i read the context attribute bound to pdfsource, will i get the updated data in the form? Or should i do anything more to get the desired result?
Thanks and Regards,
Ram

Hi Ram,
In my Project we solved the same type of situation in following Procedure.
1.) First after the User enters data in to the Form u hav to read it from the PDF
      by using this code .It converts the Data in to XML Format.
public String getData(String pdfSource) throws EJBException
ByteArrayOutputStream pdfSourceOutputStream = new ByteArrayOutputStream();
try
   InputStream pdfSourceInputStream = new FileInputStream(new File(pdfSource));
   IOUtil.write(pdfSourceInputStream, pdfSourceOutputStream);
   pdfSourceInputStream.close();
catch (Exception e)
   System.out.println(e.getMessage());
   throw new EJBException(e.getMessage());
IWDPDFObject pdfObject = WDPDFObjectFactory.getPDFObject();
pdfObject.setPDF(pdfSourceOutputStream);
ByteArrayInputStream dataInputStream =                                      (ByteArrayInputStream) pdfObject.getData();
if (dataInputStream == null)
    return(null);
else
    try
      String output = formatData((InputStream) dataInputStream);
      return(output);
    catch (Exception e)
       System.out.println(e.getMessage());
       throw new EJBException(e.getMessage());
2.) Then u can get the data from tht XML code easily & store it in the Data Base where u need.
--> For more Details watch the " TutWD_PdfObject " Sample Application from this site .
I Think It helps u lot.
With Regards,
Roop Kumar.

Need to automatically display update date and user in update form field

Hi all,
Hopefully someone can help me with this... I am using dreamweaver cs4 and php/mysql. I have a database table that will be updated by 1-5 different people at random times. I have everything set up and working, as far as the update function, delete function, add new, etc. In my update form the last two fields are Last Updated and Last Updated By. There are fields in the table called 'last_updated' (formatted in PHPmyadmin as timestamp) and 'last_updated_by'. But how do I get them to update on their own? Right now it is showing the first entry into the field which I did in the PHPmyadmin table, but it is not updating automatically. It would be a nice field to have so that we know who has worked on the table and when it was last updated, without the user manually typing that in, which I am sure they would forget to do. By the way, users will login to this with a username and password before editing the records.
This is the code for the last row in the update form with those two fields. It is pulling the fields from the database table, but they do not update automatically...
<tr>
          <th class="blackfont" scope="row">
            <div align="right">
              <label for="last_updated">Last Updated Date:</label></div>
          </th>
          <td colspan="3" class="blackfont"><input name="last_updated" type="text" id="last_updated" tabindex="47" value="<?php echo $row_getMember['last_updated']; ?>" size="15" />
            <label for="last_updated_by">Last Updated By:</label>
            <input name="last_updated_by" type="text" id="last_updated_by"tabindex="48" value="<?php echo $row_getMember['last_updated_by']; ?>" size="15" /></td>
</tr>
Thanks!

How to update or delete records in a Complex View in Forms?

Hi,
I have a requirement to create a Form by using Complex View. Insertion is possible but updation and deletion is not working properly . I got FRM-40501 Error. I need How to update or delete records in a Complex View in Forms?
Thanks & Regards,
Hari Babu

Depending on how complex your view is, forms is not able to determine how to appropiately lock a record, when you try to update or delete a record.
One approach to using complex views in forms:
1. Set the Key-mode of the block to "Non-Updateable"
2. Mark the column which can be used to build the WHERE-condition to uniquely identify a record with "Primary Key" = "Yes"
3. For doing INSERT, UPDATE and DELETE, create an INSTEAD-OF-trigger on the view.
4. Create your own ON-LOCK-trigger in forms which does the locking of the records to update.
