Hi:
I am redesigning a module that has to get records from the database corresponding a collection of objects.

In the current implementation, for each object in a collection a JDBC call
is made to an oracle database and information for that object is obtained and mapped to an object. Obviously that causes a lot of database calls.

Is it possible to do this in a more efficient manner? How can I pass a collection of primary keys to a stored procedure and get a resultset that can be mapped back to the collection of primary keys? Is it possible using PL/SQL?

Thanks in advance for the help.

p,

Yes, it is. Please see my reply in the topic Passing Arrays to Oracle stored procedures (in this forum).

Good Luck,
Avi.
