How to update all the record for a particular column in a table based on search criteria.

Question

Hi All,
I am new to ADF. I have a requirement, where i have to perform mass update on a table.
Scenario:
Ex: I have a dept manual search region. where i search with deptId: 20. I get 20 records in my table. now i have  another region where i have a inputchoice list which contains all the columns names that exists in dept table. Beside that i have a input text box and an update button
Now user, first searches with dept id:20 and clicks on search button, where it shows 20 record in the table. He then select a column from input choicelist(ex: ManagerId), then enters new value in the input box(ex: abc) then clicks on update button.
Now i want, all the records in the ManagerId column with dept id:20 to be updated with the new value "abc"
Can anyone help me with the code.
Thanks in advance..

Hi,
If you go to your VO and generate the ViewObjectImpl, in there you can create a method which will contain two parameters, 1 the attribute name and 2 the value.
Then you can follow something like explained in this post:
ADF Tutorial: How to apply bulk actions to a view object rows
The only difference is that you will need to create a method like this:
public void updateAttribute(String attribute, Integer value){
        RowSetIterator iter = createRowSetIterator(null);
        while (iter.hasNext()){
            Row row = iter.next();
            row.setAttribute(attribute, value);
Then you expose that as a client interface and then after you filter your table by your criteria you just need to execute this method passing the right parameters.
