Hi,
Is it possible for me to create secondary database which may require
multiple key from primary db record? For example, I have item record
that may contain more than one components. I would like to create index
on item record on the components. Since the number of components is
variables, I would not like to create secondary indexes for each
component. How could I lump them into one secondary index that allow me
to use join-cursor to for instance, finding items with component A, B
and C...


TIA.
Radzi.

Hi Radzi,

The only way to do this at present is to maintain the index manually:
that is, you need to add and remove the (secondary key, primary key)
pairs in your application. This is a common feature request for
Berkeley DB and is high on our todo list.
