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 difference between raise and raise_application_error in oracle 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.

Looking for the original pages? (formerly called "Morgan's Library") You can find them here. Term: RAISE Definition: In Oracle PL/SQL, the RAISE statement is used to explicitly raise http://docs.oracle.com/cd/B19306_01/appdev.102/b14261/raise_statement.htm an exception within a PL/SQL block. It immediately stops normal execution of a PL/SQL block or subprogram and transfers control to an exception handler. It can be used to raise both system defined and user defined exceptions. If an exception is raised and PL/SQL cannot find a handler for it in the current block, the exception then propagates to successive http://psoug.org/definition/raise.htm enclosing blocks, until a handler is found or there are no more blocks to propagate to. If no handler is found, PL/SQL returns an unhandled exception error to the host environment. Example Syntax: RAISE [EXCEPTION NAME] Example Usage: The PL/SQL block below selects an employee corresponding to a given employee IDd. If no employee record is found it raises the NO_DATA_FOUND exception and displays a message. Note that NO_DATA_FOUND is a system defined exception. DECLARE L_EMP VARCHAR2(1000); CURSOR C IS SELECT ENAME FROM EMPLOYEE WHERE EMPNO = 300; BEGIN OPEN C; FETCH C INTO L_EMP; CLOSE C; IF L_EMP IS NULL THEN RAISE NO_DATA_FOUND; END IF; EXCEPTION WHEN NO_DATA_FOUND THEN DBMS_OUTPUT.PUT_LINE('No Employee exists for this employee ID.'); END; No Employee exists for this employee ID. PL/SQL procedure successfully completed.

What is a named programmer-defined exception in Oracle? Sometimes, it is necessary for programmers to name and user defined exception trap their own exceptions - ones that aren't defined already by PL/SQL. These are called Named Programmer-Defined Exceptions. Syntax We will take a look at the syntax for Named Programmer-Defined Exceptions in both procedures and functions. Syntax for Procedures The syntax for the Named Programmer-Defined Exception in a procedure is: CREATE [OR REPLACE] PROCEDURE procedure_name [ (parameter [,parameter]) ] IS [declaration_section] exception_name EXCEPTION; BEGIN executable_section RAISE exception_name; EXCEPTION WHEN exception_name THEN [statements] WHEN OTHERS THEN [statements] END [procedure_name]; Syntax for Functions The syntax for the Named Programmer-Defined Exception in a function is: CREATE [OR REPLACE] FUNCTION function_name [ (parameter [,parameter]) ] RETURN return_datatype IS | AS [declaration_section] exception_name EXCEPTION; BEGIN executable_section RAISE exception_name; EXCEPTION WHEN exception_name THEN [statements] WHEN OTHERS THEN [statements] END [function_name]; Example Here is an example of a procedure that uses a Named Programmer-Defined Exception: CREATE OR REPLACE PROCEDURE add_n

RAISE_APPLICATION_ERROR tips Oracle Database Tips by Burleson Consulting March 3, 2015 Question: What does the PL/SQL raise_application_error code do? Answer: The raise_application_error is actually a procedure defined by Oracle that allows the developer to raise an exception and associate an error number and message with the procedure. This allows the application to raise application errors rather than just Oracle errors. Error numbers are defined between -20,000 and -20,999. Oracle provides the raise_application_error procedure to allow you to raise custom error numbers within your applications. You can generate errors and their associated text starting with -20000 and proceeding through -20999 (a grand total of 1,000 error numbers that you can use). Below we illustrate the use of the raise_application_error procedure. Using the raise_application_error procedure: DECLARE Balance integer := 24; BEGIN IF (nBalance <= 100) THEN Raise_Application_Error (-20343, 'The balance is too low.');END IF;END; In this example, error number -20343 is raised if the value of nBalance isn't greater than 100, yielding a message that looks like this: ORA-20343: The balance is too low. All other numbers belong to Oracle for its own errors. The message can be anything that will fit in a varchar2(2000). The final parameter passed to the procedure is a Boolean(true/false) that tells the procedure to add this error to the error stack or replace all errors in the stack with this error. Passing the value of 'True' adds the error to the current stack, while the default is 'False'.
