What is the purpose of using bulk binds in Pro*C?

In Pro*C, the purpose of using bulk binds is to enhance performance and efficiency when dealing with multiple rows of data. Bulk binds allow the processing of multiple rows in a single operation, reducing the number of context switches between the application and the database. This can greatly improve the performance of data manipulation operations, such as inserts, updates, and deletes, by reducing the overhead associated with individual round-trips to the database.

By using bulk binds in Pro*C, developers can optimize the performance of their applications and improve scalability when working with large volumes of data, ultimately leading to better overall performance and user experience.
