Exception handling in PLSQL is a crucial feature for developers working with Oracle SQL. It allows for structured error handling and prevents code from crashing when errors occur. The sequence of exception handling blocks typically includes declaring variables, the main execution section, and finally, exception handlers to catch and handle specific or general exceptions. This feature enables developers to write robust and maintainable code that can gracefully handle errors.
