Description: The error handling function in database systems is an essential tool designed to manage errors that occur during the execution of database operations. This function allows developers and database administrators to anticipate and react to unexpected situations, ensuring that applications behave predictably even under adverse conditions. By implementing effective error handling, exceptions can be captured, relevant information about the error can be logged, and in some cases, automatic corrective actions can be taken. This not only improves the stability and robustness of applications but also facilitates debugging and code maintenance. Various structures and functions, such as `BEGIN`, `EXCEPTION`, and `END`, are commonly used to define code blocks where specific errors can be handled. The ability to customize error handling also enables developers to create specific responses for different types of failures, resulting in a smoother user experience that is less prone to interruptions. In summary, the error handling function is fundamental to ensuring the integrity and reliability of database operations, allowing users to effectively manage exceptions that may arise during the execution of their applications.
