Usage Notes PL/SQL blocks and subprograms should RAISE an exception only when an error oracle predefined exceptions makes it impractical to continue processing. You can code a RAISE statement for a given exception anywhere within the scope of that exception. When an exception is raised, if PL/SQL cannot find a handler for it in the current block, the exception propagates to successive enclosing blocks, until

a handler is found or there are no more blocks to search. If no handler is found, PL/SQL returns an unhandled exception error to the host environment. In an exception handler, you can omit the exception name in a RAISE statement, which raises the current exception again. This technique allows you to take some initial corrective action (perhaps just logging the problem), then pass control to another handler that does more extensive correction. When an exception is reraised, the first block searched is the enclosing block, not the current block.

Raise User Defined Exception In Oracle Stored Procedure
you cannot anticipate all possible errors, you can plan to handle functions for error trapping in pl/sql certain kinds of errors meaningful to your PL/SQL program. With many programming languages, unless you disable error oracle user defined exception code range checking, a run-time error such as stack overflow or division by zero stops normal processing and returns control to the operating system. With PL/SQL, a mechanism called exception handling http://docs.oracle.com/cd/B19306_01/appdev.102/b14261/raise_statement.htm lets you "bulletproof" your program so that it can continue operating in the presence of errors.

Exceptions can be internally defined (by the runtime system) or user defined. Examples of internally defined exceptions include division by zero and out of memory. Some common internal exceptions have predefined names, such as ZERO_DIVIDE and STORAGE_ERROR. The other internal exceptions can be given names. You can define exceptions of your own in the declarative part of any PL/SQL block, subprogram, or package. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. Unlike internal exceptions, user-defined exceptions must be given names. When an error occurs, an exception is raised. That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. Internal exceptions are raised implicitly (automatically) by the run-time system. User-defined exceptions must be raised explicitly by RAISE statements, which can also raise predefined exceptions. To handle raised exceptions, you w

PL/SQL supports programmers to catch such conditions using EXCEPTION block in the program and an appropriate action is taken against the error condition. There are two types of exceptions: System-defined exceptions User-defined exceptions Syntax for Exception Handling The General Syntax for exception handling is as follows. Here you can list down as many as exceptions you want to handle. The default exception will be handled using WHEN others THEN: DECLARE
