This allows you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs I get the same problem.
The New Values and Old Values collections are empty..means I can't do anything but display the orginal data again :( Does anyone else have this problem or a solution?
This type of trigger also provides an additional correlation name for accessing the parent row that contains the nested table being modified. drop table tab1; create table tab1 (c1 clob); insert into tab1 values ('Some text.'); create or replace trigger trg1 before update on tab1 for each row begin dbms_output.put_line('Old value of CLOB column: '
These triggers provide a way of updating elements of the nested table. CALL foo (ora_login_user) / CREATE OR REPLACE PROCEDURE Before_delete (Id IN NUMBER, Ename VARCHAR2) IS language Java name 'thjv Triggers.before Delete ( CHAR)'; CREATE OR REPLACE TRIGGER Pre_del_trigger BEFORE DELETE ON Tab FOR EACH ROW CALL Before_delete (:old. Ename) Within a trigger body of a row trigger, the PL/SQL code and SQL statements have access to the old and new column values of the current row affected by the triggering statement.
I am using and Array List of my own Objects with public Get/Set methods (c# style).

Row Updating event and get the old values using the e. This event operates in the same manner as for a standard asp: Grid View. Thanks, Vest I have the Session("COSTO")=e.oldvalues("COSTO") but now i want when press the button "UPDATE" from the editing row, the oldvalue save in historial table.
in what event can save this value Session("COSTO") in my table with the news values? Row Updating event you can store old values to your database.
When implementing the event handler, you can access the Form options using the form Options field of the handler's parameter.
