There are situations where a record fetch, a record insert, or a record delete operation has to be applied to a group of related records. For example, if an invoice record is being displayed, it may be necessary to retrieve all invoice items for that invoice as well. The following code fragment shows a typical c-treeDB C function to extract all items of an invoice, given the invoice number.
For more information about batch processing of records, see the section in the c-treeDB C++ Developer's Guide titled Record Batches.
