Yes...I'm aware of that and have tried also by maintaining extra table.
But how to to the following:
1. If insertion takes place, I want to return to the client the
values (with field names of course) which are inserted into the
tables. In each case table might be different.
2. If modification takes places, I want to know the values which
are modified with field names and return them to the client.
More precisely,
My C++ client --
'
'
"
Transcation begin
insert/update query to the backend is fired.
//control is tranferred to the trigger
//After trigger procedure is executed, I want at this
point the values inserted/modified so //as to pass them back
Transcation end
'
'
Pls. help

If you want to record transaction history on a table, you'll need to use
triggers and a separate table to store the history in. When the
transaction
that modified the table commits, the modification to the history table
from
the trigger will commit also, in the order they committed.
