to your PL/SQL program. With many programming languages, unless you disable error checking, a run-time error such as oracle raise exception with message stack overflow or division by zero stops normal processing and returns exception handling in oracle stored procedure example control to the operating system. With PL/SQL, a mechanism called exception handling lets you bulletproof your difference between raise and raise_application_error in oracle program so that it can continue operating in the presence of errors.

(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 write separate routines called exception handlers. After an exception handler runs, the current block stops executing and the enclosing block resume

The application is connected to Oracle database and handles oracle error messages. It works like this Try 'Do oracle operations Catch Ex as OracleException 'Handle exception End Try In the http://stackoverflow.com/questions/20769020/oracle-raise-custom-error-messages-without-conflict-with-default-error-ids database side, I'm creating some customized error messages : raise_application_error (-20000, 'Custom Error description'); My problem is that : I don't want any conflict between the Error number of default Oracle errors and mine. So I tried to use an Error Number outside default oracle interval (From 0000 to 62001) but I'm getting the error "Ora-21000 error number argument to raise_application_error. 63000 is out of range" Does anyone have a workaround ? oracle share|improve this question edited Dec 25 '13 at 4:42 asked Dec 25 '13 at 4:21 Thomas Carlton 8863924 add a comment| 2 Answers 2 active oldest votes up vote 3 down vote accepted The user-defined error code range that you can use is in the range -20000..-20999.

Answer: The raise_application_error is actually a procedure defined by Oracle that allows the developer to raise an exception and associate an in oracle 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 exception handling in -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'.

PL/SQL provides a feature to handle the Exceptions which occur in a PL/SQL Block known as exception Handling. Using Exception Handling we can test the code and avoid it from exiting abruptly. When an exception occurs a messages which explains its cause is recieved. PL/SQL Exception message consists of three parts. 1) Type of Exception 2) An Error Code 3) A message By Handling the exceptions we can ensure a PL/SQL block does not exit abruptly. 2) Structure of Exception Handling. General Syntax for coding the exception section DECLARE Declaration section BEGIN Exception section EXCEPTION WHEN ex_name1 THEN -Error handling statements WHEN ex_name2 THEN -Error handling statements WHEN Others THEN -Error handling statements END; General PL/SQL statments can be used in the Exception Block. When an exception is raised, Oracle searches for an appropriate exception handler in the exception section. For example in the above example, if the error raised is 'ex_name1 ', then the error is handled according to the statements under it. Since, it is not possible to determine all the possible runtime errors during testing fo the code, the 'WHEN Others' exception is used to manage the exceptions that are not explicitly handled. Only one exception can be raised in a Block and the control does not return to the Execution Section after the error is handled. If there are nested PL/SQL blocks like this. DELCARE Declaration section BEGIN DECLARE Declaration section BEGIN Execution section EXCEPTION Exception section END; EXCEPTION Exception section END; In the above case, if the exception is raised in the inner block it should be handled in the exception block of the inner PL/SQL block else the control moves to the Exception block of the next upper PL/SQL Block. If none of the blocks handle the exception the program ends abruptly with an error. 3) Types of Exception. There are 3 types of Exceptions. a) Named System Exceptions b) Unnamed System Exceptions c) User-defined Exceptions a) Named System Exceptions System exceptions are automatically raised by Oracle, when a program violates a RDBMS rule. There are some system exceptions which are raised frequently, so they are pre-defined and given a name in Oracle which are known as Named System Exceptions. For example: NO_DATA_FOUND and ZERO_DIVIDE are called Named System excepti
