Batch Updates

c-treeACE batch operations can greatly improve performance by reducing the number of round-trips to the server when a group of related records must be processed. V10.3 adds further capabilities to this valuable capability.

Previously, batch operations provided capabilities to either Retrieve or Delete records matching a partial key. We have now added the capability to Update a collection of records, each identified by its unique key value. This powerful feature adds a new BAT_UPD option for the mode parameter specified when calling the batch function.

The Batch Operations section of the c-tree Programmer's Reference Guide provides detailed information about these operations.
