Problem in deleting the rows in a table

I am trying to delete 1213 records from a table.
When I am selecting the rows are selected within seconds.
When I am trying to delete the same rows, the script hangs, can anybody, help in finding the issue here!

Or that there are some foreign keys defined without indexes that are forcing Oracle to do 1213 full table scans on some large child table to ensure that the data you're deleting isn't referenced by some other row.

Problem of deletion of rows in jtable, table refreshing too

Hi,
I have a table with empty rows in the beginning with some custom properties( columns have fixed width...), later user would be adding to the rows to this table and can delete, I've a problem while deleting the rows from table,
When a selected row is deleted the model is also deleting the data but the table(view) is not refreshed.
Actually i'm selecting a cell of a row, then hitting the delete button.
So the model is deleting the information, but i'm not able to c the fresh data in table( especially when the last cell of last row is selectd and hit the delete button, i am getting lots of exception)
Kindly copy the below code and execute it, and let me know,

Hi,
I've got the solution for it. As when the cursor is in cell of
a row and hit the delete button, the data in that cell is not saved,
So i'm trying to save the data first into the model then firing the action event by doing this ..
jButton2.addActionListener( new ActionListener(){
public void actionPerformed(ActionEvent actionEvent){
// If a button press is the trigger to leave a JTable cell and save the data in model
if(jTable1.isEditing() ){
String text=((javax.swing.text.JTextComponent)jTable1.getEditorComponent()).getText();
jTable1.setValueAt(text,jTable1.getSelectedRow(),jTable1.getSelectedColumn()) ;
jTable1.getCellEditor().cancelCellEditing();
// HERE DO THE DELETE ROW OPERATION

Problem in reading the row values in table display format.

Hi All
   I created UI asTable display format using three columns( name, email and resume ).
In this Resume column type is Link to Action. This entire column contains text as Resume - this element type is Link to action.
When click on Resume that respective row values I have to capture.
I have used following code, but It is capturing based on lead selection. ( On the UI, lead selection row is different and clicking on Resume row is different ).
DATA lo_nd_email TYPE REF TO if_wd_context_node.
DATA lo_el_email TYPE REF TO if_wd_context_element.
DATA ls_email TYPE wd_this->element_email.
DATA lv_email_ref LIKE ls_email-email_ref.
navigate from <CONTEXT> to <EMAIL> via lead selection
lo_nd_email = wd_context->get_child_node( name = wd_this->wdctx_email ).
get element via lead selection
lo_el_email = lo_nd_email->get_element( ).
lo_el_dashboard_1->get_attribute(
    EXPORTING
      name = `NAEM`
    IMPORTING
      value = lv_name ).
Please help me on this ..thanks in advance....

Hi,
   Just declare a variable in the parameters of the method,which u declare for the cell action.
CONTEXT_ELEMENT      type ref to                      CONTEXT_ELEMENT         as importing paramter
code:
    context_element->get_static_attributes(
      IMPORTING
        static_attributes = stru_sflight ).
this will surely solve ur problem

HI,
I want to delete the row after the display of table control. I have created push button as delete row. If I click on this push button, the selected row should get deleted.
I have written this code,
module USER_COMMAND_9000 input.
DATA OK_CODE TYPE SY-UCOMM.
OK_CODE = SY-UCOMM.
CASE OK_CODE.
     WHEN 'DELETE'.
        LOOP AT lt_source INTO ls_source WHERE mark = 'X'.
            APPEND LS_SOURCE TO LT_RESTORE.
            DELETE TABLE LT_SOURCE FROM LS_SOURCE.
            SOURCE-LINES = SOURCE-LINES - 1.
        ENDLOOP.
But I'm unable to delete the selected rows, It is getting deleted the last rows eventhough I select the other row.
So I thought of doing with respect to the field.

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.

You mean when you click on the hyperlink you want that row to disappear from the page, but not delete the row from the database until a commit/submit button is pressed?
Personally, I think I'd prefer that you have a delete checkbox next to every row and NOT remove them from the display if I was a user. You give your users a chance to change their mind about their choice, and when they're done they can see exactly which rows will be deleted before they commit.
You know your problem, of course, so you might have a good reason for designing it this way. But I'd prefer not removing them from the display. JMO - MOD

How to restrict the user(Schema) from deleting the data from a table

Hi All,
I have scenario here.
I want to know how to restrict a user(Schema) from deleting the values from a table created in the same schema.
Below is the example.
I have created a table employee in abc schema which has two values.
EMPLOYEE
ABC
XYZ
In the above scenario the abc user can only fire select query on the EMPLOYEE table.
SELECT * FROM EMPLOYEE;
He should not be able to use any other DML commands on that table.
If he uses then Insufficient privileges error should be thrown.
Can anyone please help me out on this.

Hi,

Hi Frank,
Thanks for the reply.
Can you please elaborate on how to add policies for a table for just firing a select DML statement on table.See the SQL Packages and Types manual first. It has examples. You can also search the web for examples. This is sometimes called "Virtual Private Database" or VPD.
If you have problems, post a specific question here. Include CREATE TABLE and INSERT statements to create a table as it exists before the policies go into effect, the PL/SQL code to create the policies, and additonal DML statements that will be affected by the policies. Show what the table should contain after each of those DML statements.
Always say which version of Oracle you're using. Confirm that you have Enterprise Edition.
See the forum FAQ {message:id=9360002}
The basic idea behind row-level security is that it generates a string that is automatically added to SELECT and/or DML statement WHERE clauses. For example, if user ABC is only allowed to query a table on Sunday, then you might write a function that returns the string
USER != 'ABC'
OR      TO_CHAR (SYSDATE, 'DY', 'NLS_DATE_LANGUAGE=ENGLISH') = 'SUN'So whenever any user says
SELECT *
FROM    table_x
;what actually runs is:
SELECT *
FROM    table_x
WHERE   USER != 'ABC'
OR      TO_CHAR (SYSDATE, 'DY', 'NLS_DATE_LANGUAGE=ENGLISH') = 'SUN'
;If you want to prevent any user from deleting rows, then the policy function can return just this string
0 = 1Then, if somone says
DELETE employee
;what actually gets run is
DELETE employee
WHERE   0 = 1
;No error will be raised, but no rows will be deleted.
Once again, it would be simpler, more efficient, more robust and easier to maintain if you just created the table in a different schema, and not give DELETE privileges.
Edited by: Frank Kulash on Nov 2, 2012 10:26 AM
I just saw the previous response, which makes some additional good points (e.g., a user can always TRUNCATE his own tables). ALso, if user ABC applies a security policy to the table, then user ABC can also remove the policy, so if you really want to prevent user ABC from deleting rows, no matter how hard the user tries, then you need to create the policies in a different schema. If you're creating things in a different schema, then you might as well create the table in a different schema.

Deleting a row from parent table

Dear Guru's
I am having two table with parent - child relationship. My problem is when I am deleting a row from parent table the curresponding child row from child table also should be deleted.
My Primary table 'Employee, EMPID Primary key
Child table 'Privilage' inthis EMPID referencing the EMPID of Employee table
My need is when I am deleting a row from parent table the curresponding child row from child table also should be deleted
I issued the SQL query like,
delete from employee where empid='12345' cascade constraints;
Then it showing me error like,
ERROR at line 1:
ORA-00933: SQL command not properly ended
Please resolve my issue , Its Top urgent
Thanks & Cheers

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);

Problem in deleting a row

hi,
I have a table with set of values. added three buttons below that in table. add row, delete row, save.
if I delete the row and save and if i come again to that application still that deleted row remains. what might be the problem?

you can use flag in your internal table,
when you press delete button after selecting the particular row, set the flag for this entry in itab.
now in save event loop through the table checking flag, and delete enteries. now bind the table again by the itab.

How to delete the row created by AddAnotherRow Button

Hi Every one,
We have a seeded page in Oracle Sales Opportunity Update.
Here we have an activities region where we can add activities by clicking on AddAnotherRow Button.
But there are no restriction of the row created in activities
The issue we are facing is the end users are clicking the AddAnotherRow Button but not able to clear the row from the table.
Is there any functionality where the user can delete the row created by AddAnotherRow
Regards,
Krishna

Hi Krishna,
If the delete functionality is not available on the page then there is no other way, you need to implement it.

i am giving my code see this and give me the answer?
loop at it_data into wa_data .
Validate Cost Center
    READ TABLE it_kostl INTO wa_kostl WITH KEY kostl = wa_data-kostl BINARY SEARCH.
    IF sy-subrc NE 0.
      PERFORM update_error_log USING wa_data
                                     text-004.
    ENDIF.
Validate source file material ( material number )
loop at it_mara into wa_mara .
read table it_ausp into wa_ausp with key atwrt = wa_data-i_matnr .
           if sy-subrc NE 0 .
   PERFORM update_error_log USING wa_data
                                       text-002.
delete it_data-objek .
     else.
read table it_mara into wa_mara with key matnr = wa_ausp-objek .
       if sy-subrc EQ 0 .
       wa_data-objek = wa_mara-matnr.
       wa_data-matkl = wa_mara-matkl.
     ENDIF.
     Modify it_data from wa_data .
endif.
*endloop.
Validate unit of measure (unit)
    READ TABLE it_t006 INTO wa_t006 WITH KEY msehi = wa_data-unit .
    IF sy-subrc NE 0.
      PERFORM update_error_log USING wa_data
                                     text-003.
    endif.
Validate delivery location ( storage location )
    READ TABLE it_lgort INTO wa_lgort WITH KEY del_loc = wa_data-del_loc.
    IF sy-subrc NE 0.
      PERFORM update_error_log USING wa_data
                                     text-001.
         if wa_data-flag ='x' .
      delete it_data from wa_data .
    endif.
    ENDIF.
endloop.

Hi Naren,
First get the index number of the IT_data table and store it in one variable whose declaration like this.
data: tabix type sy-tabix.
while reading the internal table it_data set the tabix variable.
tabix = sy-tabix.
Instead of the above use below one.
Delete it_data-objek
Use the Below statement it will delete the row from the internal table.
Delete it_data-objek index tabix
Thanks,

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!

I ended up rebuilding the server. Deployed a new OVA, installed PI 2.2 and patched the Critical Fixes ( PI2.2.1 POODLE fix and PI 2.2.1 Maintenance Release). The I applied the device pack 2.2. Finally I restored the backup. The application has been running stable. Goodluck.
