Oracle 8i and higher databases natively support parameter arrays, and the Oracle driver, in turn, supports them when connected to these versions of Oracle databases. When designing an application for performance, using native 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.If the database does not support parameter arrays, the Oracle driver emulates them so that you can design your applications to use arrays of parameters and take advantage of the performance improvements where applicable. The driver emulates parameter arrays by sending individual rows to the database.
