Hi,
I have some multimedia content in my database stored using interMedia.
Because there is no way, to declare these objects (ORDImage, ORDVideo, ...)
as unique (or is it possible?), I wanted to write a trigger, wich ensures
this constraints.
The trigger fires before insert and update operations for each row.
In this trigger a have to check, if the same object is already in the table.
Therefore I must read the complete table and perform my checks. The problem
is, that this tricker throws an error, that "table is modified at the moment
an the trigger can't see this". Oracle suggestion to solve this, is not to
read this table in the trigger - not very good for me. I suppose there is a
lock at the table. Do you have any suggestions, how I could implement the
trigger?
Thanks Christian
