Some databases and their ODBC drivers allow clients to control the number of rows that will be physically transferred between the server and the client in one logical bind or fetch. These features are called array binding and array fetching. Using array binding and array fetching can greatly improve the performance of many applications by trading buffer space for time (network traffic).

From Cincom® ObjectStudio® 8.4 and Cincom® VisualWorks® 7.9, Cincom starts to support array binding and array fetching in ODBC connects.
