Is it a way to delete all rows in a table?
I have tried to send <ns0:Rows>*</ns0:Rows> with no luck.

I'm not expert in Biztalk but one of the options to call stored procedure that contains the delete script:

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);

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.

BPM question - Delete all entries in a table and Insert data

Hello,
I'm new to PI BPM and have this scenario to implement.
I'm supposed to delete all entries in a table and then insert data to the same table.
Is BPM necessary? If it is, what is the best practice to implement my scenario?
I want to make sure that all entries were successfully deleted before insert data.
How do I check if all entries in the table were deleted successfully before
initiating insert.
Thank you.
-Won

Hi Won,
Yes, this is possible without BPM.
You have to create 2 separate mappings, each for deleting & inserting the records.
You will have 2 different Interface mappings as well.
But in ID, create a single interface determination.
In that, configure Deletion interface mapping first and in the second row, configure Insertion interface mapping.
Please make sure that the parameter 'Mainain Order At runtime' is checked in interface determination.

How to delete all rows data from database

Hello All.
I have a database username 'abc'. This database contain 123 tables & have many data.
I want to empty all the database. Is it possible that clear all the database with a single query.
if yes then kindly tell me about the query .
Thanks
Diamond

Keep in mind that you cannot rollback the truncate command.
Once you truncate a table all of it's data AND statistics are gone.
If you do not want to use PL/SQL to delete all rows you can generate a script by SQL
SCOTT@ORCL> SELECT ' TRUNCATE TABLE '|| TABLE_NAME||';' FROM USER_TABLES;
'TRUNCATETABLE'||TABLE_NAME||';'
TRUNCATE TABLE BONUS;
TRUNCATE TABLE SALGRADE;
TRUNCATE TABLE DEPT_LOV;
TRUNCATE TABLE TITLE;
TRUNCATE TABLE TEST_DATE;
TRUNCATE TABLE DEPT;
TRUNCATE TABLE REP;
TRUNCATE TABLE REP_PARAM;
TRUNCATE TABLE EMP;
10 rows selected.
SCOTT@ORCL> SELECT 'DELETE FROM '|| TABLE_NAME||';' FROM USER_TABLES;
'DELETEFROM'||TABLE_NAME||';'
DELETE FROM BONUS;
DELETE FROM SALGRADE;
DELETE FROM DEPT_LOV;
DELETE FROM TITLE;
DELETE FROM TEST_DATE;
DELETE FROM DEPT;
DELETE FROM REP;
DELETE FROM REP_PARAM;
DELETE FROM EMP;
10 rows selected.

Delete all rows except 10 random rows

Hi,
how can I delete all rows from table JOBS except 10 random rows?
Someone asked it before (not here..): http://stackoverflow.com/questions/10820105/t-sql-delete-except-top-1
but I didn't understand the answer, and I don't think it will work in PL/SQL.
If the answer in StackOverflow does works in PL/SQL, I will glad if someone explains me with better example,
If the answer in StackOverflow does'nt work in PL/SQL, I will glad if someone gives me an example.
thanks!

Actually I found a problem in this solution.
delete from jobs where rowid not in (select rowid from jobs where rownum<=10) ;I used the above code to delete all rows except 10 in JOB_HISTORY table, but for some reason the rows that were chosen were only in the range in which (144<=EMPLOYEE_ID<=146).
I tried this several times and always i stayed with rows in this range.
Here are the queries:
SQL> select employee_id from job_history;
EMPLOYEE_ID

Add / Delete a row in a table without using a button

Hi,
I was just wondering if it was possible to remove or add a row in a table without using the button? I noticed that in all examples, it always involve putting code in the button click event but I wanted to add or delete a row in a table based on the fact if the row contains a certain value or not. Is that possible?
Much appreciated,
Vincent

Vincent,
Here is the updated file..
https://acrobat.com/#d=bVDBNM0pnS2IpfE58V01Tg
You have checked the checkbox "Repeat subform for each Row" for Header Row under IndTable1. You need to do at Row1 level of Table1.
I bound the Row1 of Table1 to <Row1> tag in your XML which can repeat multiple times.
I wrote the code in the Doc Ready event of the Test1 field to check whether the value is existing or not. If it does not have a value, then I am removing the instance of the Row1 by passing the current index.. (You can check the code)..
While creating a data connection using XML you need to make sure that the below structure is repeated atleast 2 times. And while previewing you can use make a copy of this same XML and remove Row1.
<Row1>
<Test1>Individual Name 1</Test1>
</Row1>
Thanks

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.

Delete all data of a table in Oracle before insert operation in BizTalk.

Hi,
I need to delete all the data of a table from Oracle before insert data into it from BizTalk. I can't create stored procedure on the oracle table or how to create a xml of the delete schema of the oracle table in the BizTalk with filter node has a blank
value because i need to delete all the data of the table so that i will send this xml as delete operation.
Thanks in advance.
Regards,
Gyan

You need to create two schemas: One for deleting all rows and one for inserting.
Then combine these Schemas into one and use the "CompositeOperation" SOAP Action Header.
Something like the below (a SQL Example, so the Schemas needs to be replaced by WCF-Oracle syntax)
<Request xmlns="http://CompositeTest.CompositeSchema">
<Delete xmlns="http://schemas.microsoft.com/Sql/2008/05/TableOp/dbo/Employee">
<Rows>
<Employee xmlns="http://schemas.microsoft.com/Sql/2008/05/Types/Tables/dbo">
</Employee>
</Rows>
</Delete>
<Insert xmlns="http://schemas.microsoft.com/Sql/2008/05/TableOp/dbo/Employee">
<Rows>
<Employee xmlns="http://schemas.microsoft.com/Sql/2008/05/Types/Tables/dbo">
<Name>John</Name>
<Designation>Manager</Designation>
<Salary>100000</Salary>
</Employee>
</Rows>
</Insert>
</Request>

Delete all record in a table, the insert speed is not change.

I have an empty table, and i insert a record need 100ms,
when this table has 40,0000 record, i insert a record need 1s, this is ok, because i need do a compare based an index before insert a record, so more record, need more time.
The problem is when i delete all record in this table, the insert time is still 1s, not reduce to 100ms.Why?

Hello,
Read through this portion of oracle documentation
http://download.oracle.com/docs/cd/B19306_01/server.102/b14220/logical.htm#CNCPT004
The reason is still taking 1s, because when you inserted 400K record because HWM (The high water mark is the boundary between used and unused space in a segment.) moved up. And when you deleted all the records your HWM still at the same marker and didn't get to reset to 0. So when you insert 1 record it lookings for free space and after finding (generally a regular inserts got 6 steps it inserts data). If you truncate your table you and try it again it will be faster as your HWM is reset to 0.

Select All rows in WebDybpro Tables

Hi All ,
I am working on NWCE 7.1 . i have table in my UI. and want to give slect all rows functionality in table. in NWCE is there
any way to give select all rows in table with out using , button and writing action to iterate node bound to table.
also i want to know about RowCreator ui element for table.(when we right click on table we get insert -> rowcreator). How this works
Thanks in advance
Regards
Kavita

Hi Kavita,
The row creator Ui element is not visible in table itself you can see it only in outline window.
and in its on create event you have to write the code which i have provided above. it will not be visible in table at design time but at run time when you will click on the last rows lead selection it will call the associated event and one row will be added to the table.

Jeetendra

Select all rows in af:table

Hi,
I need to select all rows in af:table, not only on current page.
I have following code on custom select all action:
getTable2().getSelectionState().addAll()and on button that needs to perform some action on selected rows I have this code
        Set selectedRowSet = getTable2().getSelectionState().getKeySet();
        if (!selectedRowSet.isEmpty()) {
            Iterator it = selectedRowSet.iterator();
            while(it.hasNext()) {
                Key key = (Key)it.next();
       }selectedRowSet.iterator() method throws java.lang.ClassCastException: oracle.jbo.Key.
When I select rows with af:tableSelectMany, which is inside selection facet and selects only rows on current page, this works fine.
Any ideas?
Thanks

Hi,
you can only access those data that is queried and part of the CollectionModel to the time you select all
   RichTable _table = employeesBackingBean.getEmployeeTable1();
   RowKeySet rks = new RowKeySetImpl();
CollectionModel model = (CollectionModel)_table.getValue();
int rowCount = model.getRowCount();
      for (int i = 0; i < rowCount; i++) {
           model.setRowIndex(i);
           //note that in the simple POJO case, the row key is the same
           //as the index. However, it would be wrong to just rely on this
           //because other models or custom table models my return a more
           //comples key. Therefore we iterate over the available rows to
           //obtain the keys.
           Object key = model.getRowKey();
           //add the row keys to the RowKeySet to mark selected
           rks.add(key);
   _table.setSelectedRowKeys(rks);
   AdfFacesContext.getCurrentInstance().addPartialTarget(_table);Frank
