Deleting a row from a table control through right-click menu

I have a table control. I want to delete a row from it when a user right clicks on a particular row and selects "Delete row" menu item. I have managed the creation of menu item but have not been able to delete the row which is right clicked and the menu item "Delete row" is selected. Guidance required! Thanks!

It's irrelevant whether the table is a control or indicator. See attached VI.
Hi smercurio,
please see the attached picture. In my previous post i mean the different in the menu. The red marked function is not available, if the table is an indicator. LV8.5!

situation is.
created table control in se51 which will display the data of a table.
how could i select a line from the table control ?
how could i delete the selected lines form the table.
thanks in advance

Change the Table Control attributes such that user can only select a single record(row).
<u>Tip to delete a selected record</u>
1) write a module 'Mark' in the PAI as below
PROCESS AFTER INPUT.
MODULE cancel AT EXIT-COMMAND.
LOOP WITH CONTROL table_view.
MODULE read_table_control.
FIELD flag MODULE mark ON INPUT.
ENDLOOP.
MODULE user_command_0100.
2) Module Mark is below.
MODULE mark INPUT.
CHECK flag = 'X'.
x = table_view-top_line + sy-stepl - 1.
Delete itab INDEX x.
ENDMODULE. " mark INPUT
Table_view is the TableControl Name.
'flag' is of type char(1) available in the Internal table which was assigned to the select option in the table control.
<u>award if uesful</u>

Then it showing me error like,

Choosing How Foreign Keys Enforce Referential Integrity
Oracle Database allows different types of referential integrity actions to be enforced, as specified with the definition of a FOREIGN KEY constraint:
Prevent Delete or Update of Parent Key The default setting prevents the deletion or update of a parent key if there is a row in the child table that references the key. For example:
CREATE TABLE Emp_tab (
FOREIGN KEY (Deptno) REFERENCES Dept_tab);Delete Child Rows When Parent Key Deleted The ON DELETE CASCADE action allows parent key data that is referenced from the child table to be deleted, but not updated. When data in the parent key is deleted, all rows in the child table that depend on the deleted parent key values are also deleted. To specify this referential action, include the ON DELETE CASCADE option in the definition of the FOREIGN KEY constraint. For example:
CREATE TABLE Emp_tab (
    FOREIGN KEY (Deptno) REFERENCES Dept_tab
        ON DELETE CASCADE); Set Foreign Keys to Null When Parent Key Deleted The ON DELETE SET NULL action allows data that references the parent key to be deleted, but not updated. When referenced data in the parent key is deleted, all rows in the child table that depend on those parent key values have their foreign keys set to null. To specify this referential action, include the ON DELETE SET NULL option in the definition of the FOREIGN KEY constraint. For example:
CREATE TABLE Emp_tab (
    FOREIGN KEY (Deptno) REFERENCES Dept_tab
        ON DELETE SET NULL);

Deleting a row from a table containing CLOB as one of the columns

When i delete a row from a table which contains a CLOB (internal clob) i.e. CLOB or BLOB column, Will the CLOB data will also be deleted ? I understand that what exactly stored in the CLOB column is the clob locator which points to the actual data.
So, when I delete this row, the clob locator will be deleted, but will the actual data what this locator is pointing to is also deleted ??? if not what is the process to delete the data the locator is pointing to when the row containing the locator is deleted ? If this is not happening then the actual data might become an orphan data which nobody has access to, will automatic garbage cleaning occurs on a frequent intravels to delete unaddressed data residing on the database server ?
Thanks in advance for the help, can email me at [email protected] alternatively.
Regards,
Srinivasa C.

Michael,
Thanks very much for your inputs, here are the results i got when i tried the way you explained in your answer, the TRUNCATE command made the actual size back to normal, but the delete is not the same, so, how can i delete the data that a particular clob locator may point to ?
truncate would delete all the rows of the table, which might not serve my purpose, i would like to delete a row and also it's associated clob data from the database! is there anyway to do this ?
is there any limitation on the ool_sample size? i am basically a c++ programmer, i am looking for some function like FREE which would free the allocated memory to the clob once the locator is deleted.
your help is greatly appreciated - Thanks!
:-) Srini.

Deleting Multiple Rows From Multiple Tables As an APEX Process

Hi There,
I'm interesting in hearing best practice approaches for deleting multiple rows from multiple tables from a single button click in an APEX application. I'm using 3.0.1.008
On my APEX page I have a Select list displaying all the Payments made and a user can view individual payments by selecting a Payment from the Select List (individual items are displayed below using Text Field (Disabled, saves state) items with a source of Database Column).
A Payment is to be deleted by selecting a custom image (Delete Payments Button) displayed in a Vertical Images List on the same page. The Target is set as the same page and I gave the Request a name of DELETEPAY.
What I tried to implement was creating a Conditional Process On Submit - After Computations and Validations that has a source of a PL/SQL anonymous block as follows:
BEGIN
UPDATE tblDebitNotes d
SET d.Paid = 0
WHERE 1=1
AND d.DebitNoteID = :P7_DEBITNOTEID;
INSERT INTO tblDeletedPayments
( PaymentID,
DebitNoteID,
Amount,
Date_A,
SupplierRef,
Description
VALUES
( :P7_PAYMENTID,
:P7_DEBITNOTEID,
:P7_PAID,
SYSDATE,
:P7_SUPPLIERREF,
:P7_DESCRIPTION
DELETE FROM tblPayments
WHERE 1=1
AND PaymentID = :P7_PAYMENTID;
END;
The Condition Type used was Request = Expression 1 where Expression 1 had a value of DELETEPAY
However this process is not doing anything!! Any insights greatly appreciated.
Many thanks,
Gary.

...the "button" is using a page level Target,...
I'm not sure what that means. If the target is specified in the definition of a list item, then clicking on the image will simply redirect to that URL. You must cause the page to be submitted instead, perhaps by making the URL a reference to the javaScript doSubmit function that is part of the standard library shipped with Application Express. Take a look at a Standard Tab on a sample application and see how it submits the page using doSubmit() and emulate that.

How to delete multiple rows from ADF table

How to delete multiple rows from ADF table

Hi,
best practices when deleting multiple rows is to do this on the business service, not the view layer for performance reasons. When you selected the rows to delete and press submit, then in a managed bean you access thetable instance (put a reference to a managed bean from the table "binding" property") and call getSeletedRowKeys. In JDeveloper 11g, ADF Faces returns the RowKeySet as a Set of List, where each list conatins the server side row key (e.g. oracle.jbo.Key) if you use ADF BC. Then you create a List (ArrayList) with this keys in it and call a method exposed on the business service (through a method activity in ADF) and pass the list as an argument. On the server side you then access the View Object that holds the data and find the row to delte by the keys in the list
Example 134 here: http://blogs.oracle.com/smuenchadf/examples/#134 provides you with the code

Deleting a row from a table using jsp

Given a table in a jsp, can an user click on a row of that table and retrieve the information so that the program can delete a record from a database table?
most of the tables that I have seen are static, the user cannot interact with them(specially when the user wants to delete several records from a database table).
Can anyone suggests a good book or way of deleting a row from table using jsp.

eg use a column in the table that has a radio button or check box,
on submit, get all the rows that are checked, using the row as an index into your db store, get the key and use the key to issue the sql delete command.

9999-----------------044-------------9191--------------03/05/1980
9999-----------------055-------------9191--------------03/06/1989
My goal is to delete employee records for those employee which contains multiple values for JOB_NO
equal to 8181, (JOB_NO= 8181) with new start_dateS.
We need to keep only one record for JOB_NO 8181 which contains oldest start_date.
Here is the delete statement for the single record.
delete from emp
where empno = 7777 and job_no = 8181 and start_date in ('03/01/2002','06/24/1996);
So how could I delete thousands records from the table with this logic?
After deleting multiple records table should be as below:
select * from emp;
EMPNO--------DIVISION--------JOB_NO---------START_DATE
1111-----------------011-------------8181--------------04/10/1999
2222-----------------011-------------3131--------------05/11/2005

7777-----------------033-------------8181--------------12/02/1991
9999-----------------044-------------9191--------------03/05/1980
9999-----------------055-------------9191--------------03/06/1989

Here's one way to do it. I think this fits your business rules. At least it matches the output for your first example. It uses an analytic. I just like using them.

Deleting one row from a table view

hi i have one tableview model. At the footer of this tableview there are 2 buttons add and delete. I want that when I press the delete button one row must be deleted. I have written one ondel event.I have to implement the logic inside that.Can anyone help me with the logic?

Hey Sumana,
Check the row of the table view u want to delete.Iterate through all the rows from the top of the Table View and copy it into another new array.While doing so, check whether the row is selected or not.If it is not selected,
then copy the content into the new array and if it selected,skip that particular row and start copying from the next row.proceed till the end of the TableView.At the end initialize this new array to the model of the Table View.u have a Table View with the specified row deleted now.

Stored procedure to delete a row from a table

I have forgotten how to do this and cant find my college notes so here goes...
How do you create a stored prcedure to delete a row of data from a table, I want to pass in three parameters to identify the unique row. Any help would be great

Since you use the work hyperlink, I'm assuming that you are developing some sort of web-based front end. If you are having flow control issues, you probably want to address your question to a forum that specializes in your particular front-end language/ environment/ framework. A JSP app using Struts, an ASP.Net app using C#, and a PHP app will all have rather different approaches to state control and page flow.

Get all rows from a table control

Hi All,
I have a table control with one column. What function should I use to retrieve all the rows ? Do I need to iterate row by row and read each row or is it possible to do it in one function ?
Thanks,
Kanu
Solved!
Go to Solution.

Supposing vells in the column have all the same data type, you can retrieve the whole column with a single instruction:
GetTableCellRangeVals (panel, control, VAL_TABLE_COLUMN_RANGE (1), array, VAL_COLUMN_MAJOR);
The array passed must be large enough to retrieve all data. Alternatively, you may substitute the macro VAL_TABLE_COLUMN_RANGE with the appropriate MakeRect instruction.In case your table was dinamically built, you can obtain the nu,ìmber of rows using GetNumTableRows and dimension your array accordingly.
The above macro is defined in userint.h together with some other useful macros that can be used to access data in a table.
There are some precautions to take in case of string values or some cell type (ring, combo box, button...) that are described in the hell for the function.
Proud to use LW/CVI from 3.1 on.
