When designing an application, using parameter arrays for bulk inserts or updates, for example, can improve performance. Refer to Chapter 5 “Designing ODBC Applications for Performance Optimization” in the DataDirect Connect Series for ODBC Reference for more information about using arrays of parameters to improve performance.Because Sybase databases do not support parameter arrays natively, the Sybase Wire Protocol driver emulates them by sending T-SQL batches of Insert or Update statements to the database, which will improve performance.
