Deleting a row from advance table:urgent

Hi All,
I am using Advance table with "Add Another Row" button.Situation is like this, i have an empty row and an exsist row in my Table. Against each row i have a Delete image.Now my problem is, when I am clicking on the Delete image, i am getting the empty row id which is there is the VO cache,not the one against which i have clicked on the Delete image.Please help me to solve this problem.
Thanks in Advance,
Vikram

For the Delete image, why dont you enable a firePartialAction on that and use SPEL binding to pass a unique id (like an <object>_id) as an EVENT PARAM to the Controller. From there on you can pass it to the AM and delete that particular row.
For adding a new row, if you use the default add row feature in the advanced table and set the Insert Rows Automatically property to true, it should take care of inserting the rows by default at the end of your existing rows, without you having to write any code for it.
If, on the other hand, you want to manually add the new row yourself, such as for defaulting some values into the new row, then you might want to explore if insertRowAtRangeIndex will work.

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

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);

Select from nested table

Hi,
I create following types and table:
CREATE OR REPLACE TYPE obj_query AS OBJECT
(emp_id NUMBER(6)
,emp_first VARCHAR2(20)
,emp_last VARCHAR2(25));
CREATE OR REPLACE TYPE tab_query AS TABLE OF obj_query;
CREATE TABLE queryEmp
(id_row NUMBER
,beginTrans VARCHAR2(15)
,queryA VARCHAR2(100)
,resultEmp tab_query)
NESTED TABLE resultEmp
STORE AS nested_queryEmp;
I would like the output of the table queryEmp like this:
id_row beginTrans queryA emp_id emp_first emp_last
1 15:00 Select1 100 Joe King
101 John Queen
2 15:10 Select2 100 Leo King
101 Mett Queen
But Can I get this result with only SQL SELECT statement from this table?
I don't want to use PL/SQL, only SELECT in SQL*Plus.
Thank you
I'm sorry but output looks so bad.
So, I want to get the one row of id_row, beginTrans, queryA and all rows of nested table dmlStats to this "main" row and so on.
But not in PL/SQL
I hope, you understand me.
Thanks

Deleting Rows From A Table After Running a Report

I've created a report that inserts rows into a table on the asp page then calls a BI Publisher report to display the data. After running the report in BI Publisher I need to delete the rows from the table that had just been inserted. How is the best way to go about this in BI Publisher?

The best way I know of would be to use an "afterReport trigger".
An afterReport trigger fires after the XML output has been generated.

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

Copying table rows from one table to another table form

Hi
I have a problem about Copying table rows from one table to another table form.On jsf pages if you enter command button go anather jsf page and it copy one row to another table row. But when i execute this process for table FORM it doesn't copy I wrote a code under "createRowFromResultSet - overridden for custom java data source support." Code block is:
ViewRowImpl value = super.createRowFromResultSet(qc, resultSet);
try{
AdfFacesContext fct = AdfFacesContext.getCurrentInstance();
Number abc = (Number)fct.getProcessScope().get("___");
value.setAttribute("___",abc);
}catch(Exception ex){System.out.println(ex); }

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.

How NOT to restrict no of rows from two tables

I have two identical tables Invoice and Payment. The only difference is Invoice_id,Invoice_Amt and Payment_id,Payment_Amt columns that shows different ids and amounts. The bank_ids, names, account_types are same. Invoice table has 3 rows and Payment has 2. Simply meaning that there were 3 invoices generated but the bank received 2 payments. I want to show Invoice_Amt and Payment_Amt using sql query. But its giving me total 6 rows. Whereas, I want 3 from Invoice and 2 rows from Payment table to show side-by-side.
CREATE TABLE invoice
( invoice_id NUMBER
bank_id NUMBER,
bank_name VARCHAR2(256),
invoice_amount NUMBER);
----Invoice table has 3 rows showing 3 Invoice Amts
CREATE TABLE payment
( payment_id NUMBER
bank_id NUMBER,
bank_name VARCHAR2(256),
payment_amount NUMBER);
----Payment table has 2 rows showing 2 Payments
After executing this sql statement below, I get 6 rows:
select inv.invoice_amount,pymt.payment_amount from invoice inv,payment pymt where inv.bank_id=pymt.bank_id;
How can I show 3 rows for Invoice and 2 for Payment..?
Thank you.

Hi,
So you want
the 1st invoice to appear side-by-side with the 1st payment,
the 2nd invoice to appear side-by-side with the 2nd payment,
the nth invoice to appear side-by-side with the nth payment.
But, if there are an uneqaul numner of payments and invoices, all the payments and all the invoices must still be shown, alone on a row if necessary.
That sounds like a job for FULL OUTER JOIN.
Use the analytic ROW_NUMBER fucntion to determine which is the 1st, 2nd, ..., nth row in each table, for each bank.
WITH     invoice_plus_r_num     AS
     SELECT     bank_id, bank_name
     ,      invoice_amount
     ,     ROW_NUMBER () OVER ( PARTITION BY bank_id, bank_name
                               ORDER BY         invoice_id
                       )         AS r_num
     FROM    invoice
,     payment_plus_r_num     AS
     SELECT     bank_id, bank_name
     ,      payment_amount
     ,     ROW_NUMBER () OVER ( PARTITION BY bank_id, bank_name
                               ORDER BY         payment_id
                       )         AS r_num
     FROM    payment
SELECT       NVL (i.bank_id,   p.bank_id)          AS bank_id
,       NVL (i.bank_name, p.bank_name)     AS bank_name
,       i.invoice_amount
,       p.payment_amount
FROM          invoice_plus_r_num     i
FULL OUTER JOIN     payment_plus_r_num     p ON   i.bank_id     = p.bank_id
                                    AND     i.bank_name     = p.bank_name
                            AND     i.r_num          = p.r_num
ORDER BY bank_id     -- you can use column aliases here
,       bank_name
,       NVL (i.r_num, p.r_num)
;You mentioned something about accounts, but didn't include that in the CREATE TABLE statements. You'll probably want to add that wherever I used bank_id and bank_name, above.
Are invoce and payment actually views, rather than tables? If not, you should have a separate bank table, and only include the bank_id in the other tables.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using.

Select unique rows from two tables...

Hi,
I have two tables, replies1 and replies2.
SQL> desc replies
Name Null? Type
URN VARCHAR2(36)
ADDRESS VARCHAR2(18)
FILESIZE NUMBER
AS_NUM VARCHAR2(6)
SQL> desc replies2
Name Null? Type
URN VARCHAR2(36)
ADDRESS VARCHAR2(18)
AS_NUM VARCHAR2(6)
Both of the tables have no primary keys, but I have indixes on (urn, addrss) combination on both....
I am trying to select the unique rows with (urn, address) from replies2, and then find the matching size from replies...
I am using the following query:
select distinct replies2.urn, replies2.address, replies.filesize from replies2, replies where replies2.AS_NUM like 'XYZ' and replies.urn = replies2.urn;
I cannot figure out why it won't work. the way I understand it is that, distinct will give all distinct combination of all column names that follow, which is what I want...
I know it is wrong, because the query:
select count(*) from replies2 where AS_NUM like 'XYZ' returns less number of rows than the above query.
Any help would be greatly appreciated.
Thank you
Oz.

Thanks a lot Mohan for your reply.
urn is not a unique key. Several rows could have the same (urn, address) pair in both tables. What I want is retrieve all (urn, address) rows from one table, and find the size from the other table to make a (urn, address, size). I want all unique combinations of (urn, address) to appear in the output.
AS_NUM is an empty column in replies... It would've been a lot easier if it wasn't, since then I'll just say: select distinct urn, address, filesize from replies where AS_NUM like 'XYZ';
I will try your query though and let u know how it goes. It takes quite a while to run since my tables are huge.
