Deleting rows in a table with a button

Good Day All;
I seemed to have run into a snag with trying to add a delete button in a table that will delete a row. Let me expain.
The form has 1 table that has 7 cells made up of text fields and drop downs. This table is in its own subform.
There is a button to add rows as the user requires. The code I am using to add rows: psl_list_subform.instanceManager.addInstance(1);
I have been asked to add a delete button so a user can delete rows. I have added this to the end of the table. SO each time a row gets repeated, there is a delete button. The code I am “trying” to use is;
Table4.Row1.instanceManager.removeInstance(this.parent.index);
When I click on the button to delete, nothing happens. I brought up the JavaScript debugger, there are no errors.
Any ideas what I missed.
Thanks All

Hi,
from my understanding of your form, you adding new instances of the subform "psl_list_subform" which contains a single table row.
The hierarchy that will look like "psl_list_subform.Table4.Row1.RemoveButton".
To remove an instance of the subform, from a button within the table row the script needs to refer to the 3rd parent of the remove button.
this.parent.parent.parent.instanceManager.removeInstance(this.parent.parent.parent.index);
Explaination: this = RemoveButton, 1st parent = Row1, 2nd parent = Table4, 3rd parent = psl_list_subform

How to delete rows from multiple tables when pressing button

Hi, I'm wondering how do I delete a row from two different tables at the same time when I press the Delete button. Both tables have GROUP_ID as their primary key.

Nevermind! I realized that I had "reset" before my process to delete from the 2nd table.

How to select one row in a table with radio button

Hi all.
I have a VO where there is an attribute (isDefault [String]) that identifies the default record in the view. The possible values are 'Y' for yes and 'N' for no. Obviously only one record can have the 'Y' value.
In my page I have created an ADF Table (with the usual data control drag & drop). I would to transform the default inputText of "isDefault" field with a selectOneRadio component in order to permit the user to select (and save contextually in the DB) the default row of this table.
Can you explain me how? I'm using JDeveloper 11.1.1.4.
Thanks in advance.

Cvele,
thanks for your responses. Yes, it's easier to use af:selectBooleanCheckbox but I need that the selection is mutually exclusive (only one row can be selected). >If this is possible also with the boolean checkbox please tell me how.- Let's try with CheckBox :
1. At the ViewObjectImpl level (for example, YourViewObjectImpl), add the following code:
private oracle.jbo.Key currSelectedRowKey = null;
public void doRowSelection(Key newKey) {
      // de-select old one
      if (currSelectedRowKey != null) {
          Row[] rows = findByKey(currSelectedRowKey, 1);
          if (rows != null && rows.length > 0)
               rows[0].setStatusAsBoolean(Boolean.FALSE); // cast to the appropriate row Impl class if need !
     // remember a new selected row key:
    currSelectedRowKey = newKey;
}In the ViewRowImpl, in the transient attr settter, do as follows:
public void setStatusAsBoolean(Boolean value) {
     setStatus(value.booleanValue() ? ONE : ZERO);
     if (value.booleanValue()) {
         YourViewObjectImpl vo = (YourViewObjectImpl)getViewObject();
         vo.doRowSelection(getKey());
   }   P.S. The above was not tested at all, but should give you an idea

Adding a row to a table with a button

Good day all;
I think I have now lost it... ;>))
LifeCycle Designer 8.05
Anyway, If the user of the form requires additional rows to enter infoamtion, I want them to be able to add a row using a button. I have tried using the following
Table"N".Row2.instanceManager.addInstance(1); ="N" is the table name.
I have done this on a couple of other forms but I must be missing something as I am geting the following error in the java Consol
"GeneralError: Operation failed.
XFAObject.addInstance:1:XFA:form1[0]:#subform[0]:#subform[1]:Button1[0]:click
The element [max] has violated its allowable number of occurrences."
The form is saves as a Arcobat 8 Dynamic XML form
I
Page 1 is flowed
Subform is flowed
Would someone be so kind as to point me in the right direction.

Thanks Radzmar;
You were correct.... It appears I was only looking at the bindings for the damn table not the row.......
Thanks again

How to get current row of Advanced table with no submit

I have an advanced table with an 'Add another button'. When an empty row is created by clicking this button, LOV is used on the first column to populate other fields of the row. The rows of the table carry a button called "Add dependencies" whose functionality is to take the user to a different table to add rows to a different VO. This button is just a button and not a submitButton. I am passing the row's primary key as part of the URI as Vo attribute FdTaskId={@FdTaskId}
The button works perfectly fine for database fetched rows (rows already present in the database), but, for the rows created using 'Add Another button', though LOV populates all fields including the primary key, the URI parameter passes null to the next page. That means, the VO attribute is not set. This works fine only when a 'submit' happens in the first page. For example, if I click Add another row again, then the previously inserted row passes the primary key fine as part of {@FdTaskId}.
Could you please help me how I can resolve this issue?
Thanks,
Datta

I am doing exactly that. My issues is that, VO attribute is passed correct for the table rows which are fetched from the database. For the table rows which got created through 'Add Another button', the VO attribute passed through URI as {@FdTaskId} is returning null. The VO attribute sets only when a form submit happens. For example, after adding a row through 'Add another row' button, click the same button again to add one more row and now go back to previously added row and now you can see that its VO attribute is set ({@FdTaskId} carries value )

Is this with the Travel database or another database?
If it's another database then make sure your columns
allow nulls. To check this in the Server Navigator, expand
your DataSource down to the column.
Select the column and view the Is Nullable property
in the Property Sheet
If still no luck, check out a tutorial, like Performing Inserts, ...

Prevent user from deleting rows from all tables in his own schema

Hi,
How can I prevent user from deleting rows in all tables in his own schema.
I want the user to not able to delete rows from any existing or new tables that might be added in the future.
The user does not have the "DELETE ANY TABLE" system privilege.
Please advise.
Thanks.

Nowadays, I'd also avoid triggers (if possible).
Sometimes, when I daydream, I'm rewriting a few applications that I've contributed to as a newbie, and I'm very ashamed of it nowadays.
From what I've experienced, in retrospective, the emphasis on teaching 'Oracle stuff' has been lying far too much on PL/SQL row-by-row oriented processing instead of letting Oracle 'crunch' sets at once.
Most of my debugging hours ended up in discovering one or more database triggers 'doing stuff automagically'.
Another nice blogpost: http://rwijk.blogspot.com/2007/09/database-triggers-are-evil.html
Regarding OP's question:
I would just rethink/reconsider this requirement completely.
Correctly implementing privileges and roles seems the best way to go, yes.
Triggers? Nah...
pre-post-edit, noticed thread got updated just before posting
Don't know what you mean with 'namedropping', but I think it's legitimate to point other readers to interesting Oracle related opinions/articles that do have a technical background and lots of interesting examples.
post dreaded OTN outage edit (from here)
Again: I would just rethink/reconsider this requirement completely.
Both trigger/vpd are being used to hide a design flaw here.

How do I move a table with radio buttons to another page?

I created a document in Word, converted to PDF, added a page (which was created in Adobe Forms Central, only way to get a table with radio buttons - see below for example).
The issue I have is whilst using the Trial of Adobe XI Pro I was able to move this table up a page and place it under the header. Now that the trial has run out I cannot complete this task with other documents.
I started to edit using LiveCycle but it won't let me move the table.
We have Acrobat X Pro but when I go to edit, it directs me to edit in LiveCycle. I have tried moving the table using all of these programs. Can anyone help/guide please?

Thank you for your reply. I am new to editing a pdf and using these programs. I have subscribed to Acrobat XI Pro. When I try to edit the document it directs me to LiveCycle. I cannot move the table in LiveCycle. It won't let me, and I cannot make changes in XI Pro as I did in the trial as it directs me to edit in LiveCycle. Am going in circles.

Deleting rows from a table

COuld anyone tell me how to delete rows from a table which has millions of rows.
TIA,
Oracle user

if you are deleting all the rows, use "truncate table" in sql*plus.
or if you are deleting all but a handful of rows, then copy the rows you still want to a spare table, drop the original table, and rename the spare table back to the original table's name.
hope this helps

Dynamic table with radio buttons

I need to load a dynamic table with radio buttons that allow
the user to select an item in the table. I need to have it add a
radio button with a unique identifier for each table item.
For example: the table will load all of the seminars
locations available in a certain state, the radio button will allow
the user to select the city in which they would like to attend and
that value will get passed to the registration page. The value of
each radio button would be equal to the location_id in the database
for each of the locations in the table (The table includes the
date, day, venue, address, hotel info, etc. details for each city.)
When I add dynamic radio buttons and set the value to the
location_id in the database, it allows the user to select multiple
radio buttons. I cannot find any information on how to
resolve.....??
Any help is appreciated.

Delete row in database table

Hi!
Is there a way to delete row in database table by telling the number of the row?
Thanx!

Oh, sorry I didn't properly read your post.
Try out what rvflannery suggests.
But, for reference, you should always delete a row by it's unique ID.
Don't go deleting things, by their position on a table, because a rows position can change.

How could I insert the deleted row into another table within a trigger?

Hi,
How could I insert the deleted row into another table within a trigger? The destination table has the same columns as the source table. Since the statements are in the trigger, it is not allowed to query the source table named 'test'. Thanks! The trigger is as follows, uncompleted:
CREATE TRIGGER delete_trigger
AFTER DELETE
ON test
FOR EACH ROW
BEGIN

Hi,
I'm not sure what's wrong there.
I read the oracle docs about ANALYZE and ALL_TAB_COLUMNS, and did the following:
ANALYZE TABLE my_tab VALIDATE STRUCTURE; //went ok.
SELECT column_name
FROM all_tab_columns
WHERE table_name = 'my_tab'; //but no rows selected?
This topic might not be what this thread should be about. Here I posted a new thread:
