Oracle PL/SQL Exception Handling
Exception handling is the process of responding to the occurrence, during computation, of exceptions – anomalous or exceptional conditions requiring special processing – often disrupting the normal flow of program execution. An exception is any condition that changes the normal flow of execution. In PL/SQL, an exception is raised when an error occurs or when specific conditions are met. There are two types of exceptions: system-defined and user-defined. System-defined exceptions are automatically raised by Oracle when a program violates a RDBMS rule. User-defined exceptions must be raised explicitly by your program using either the RAISE statement or the RAISE_APPLICATION_ERROR procedure.Exception handling is the process of responding to the occurrence, during computation, of exceptions – anomalous or exceptional conditions requiring special processing – often changing the normal flow of program execution.In computer programming, an exception is an anomaly that occurs during the execution of a program. When an exception occurs, it may have an associated value, known as the exception's argument. The details of what happens when an exception is raised are highly dependent on the programming language and on the software environment in which the program is running.Exception handling in programming languages tries to handle these anomalies gracefully so that normal program execution can continue. In some cases it may mean ignoring the anomaly and continuing processing; in others it may mean terminating processing immediately; or it may mean taking some special action and then continuing processing.PL/SQL exception handling is an important part of every application. By carefully monitoring and handling exceptions, you can ensure that your application runs smoothly and efficiently. Oracle provides a number of predefined exceptions that are raised automatically when an error occurs. For example, the INVALID_NUMBER exception is raised when your application attempts to convert a string to a number and the string contains characters that cannot be converted to a number.In addition to the predefined exceptions, you can define your own exceptions. For example, you might want to raise an exception if an employee's salary is greater than a certain amount.When an exception is raised, execution of the current PL/SQL block stops and control transfers to the exception-handling part of your code. If you have not written any exception-handling code, then Oracle will display an error message and stop processing the PL/SQL block.Oracle PL/SQL Exception Handling refers to the process of managing errors that occur during the execution of a program. It is important to have a robust exception handling strategy in place so that errors can be gracefully handled and the program can continue to run without crashing. There are two types of exceptions in Oracle PL/SQL: system-defined and user-defined. System-defined exceptions are automatically raised by Oracle when an error occurs, while user-defined exceptions must be explicitly raised by the programmer.Exception handling in Oracle PL/SQL consists of four parts: The EXCEPTION clause which is used to Declare ExceptionsThe WHEN OTHERS clause which is used to Handle Unhandled ExceptionsThe RAISE statement which is used to Raise Exceptions The Pragma EXCEPTION_INIT which is used to Associate Exceptions with Oracle Error Codes.
