Hi,

I am a beginner in BDB. I wonder if there is a scheme to "Direct
Access" to the record stored in BDB?
I mean something like a pointer to the record or an address of the
record?

I think you are asking about direct access to records via key instead
of by cursor. Please expand on your question if that is not the case.

You should take a look at the DB->get method to fetch a record by key
or logical record number depending on the type of database access
(Btree, Hash, Record Number, Queue).

For more information:

You can find a description of the various Database access types here:

I think u just would like to get the direct pointer to the real record
not a database copy ...

But for BDD i think it isn't possible, (they had to guarantee that
noone will corrupted the BDD address space (like an Object model the
data shoulda be private to the database and u just return a copy of
this record)

I had got the same problem in my project, i wouldn't want to make a
copy of a readonly database just a pointer to the record would be good
.....

So i had to manually load my own hash table for BDD and make a wrapper
around BDB to handle this situation.

Best regard
