what is the difference between implicit and explicit trigger
Answer Posted / slokh
when we fire any DML operation a memory is alocated. this
memory area is called context area or cursor. data is
retieved and stored in this area
implicit cursors are automatically created by the Oracle.
when you perform any DML operation a memory has been
automatically created, and when the operation is finished
it automatically release the memory space, here every thing
is controlled by the oracle itself.
explicit cursors are the cursors, where the user defined
for which select statement the cursor is being created,
when to fetch the data, and release the memory space. on
other words the control is over the programmer.
