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
Raise_application_error Parameters
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 write query in sql for updating data in table 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 err

An exception can be either internally http://www.dba-oracle.com/t_raise_application_error.htm defined (by the run-time system) or user-defined. Examples of internally defined exceptions are ORA-22056 (value string is divided by zero) and ORA-27102 (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 your own exceptions in the declarative part of any PL/SQL https://docs.oracle.com/cd/B28359_01/appdev.111/b28370/errors.htm block, subprogram, or package. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. 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 or invocations of the procedure DBMS_STANDARD.RAISE_APPLICATION_ERROR. 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 resumes with the next statement. If there is no enclosing block, control returns to the host environment. For information about managing errors when using BULK COLLECT, see Handling FORALL Exceptions (%BULK_EXCEPTIONS Attribute). Example 11-1 calculates a price-to-earnings ratio for a company. If the company has zero earnings, the division operation raises the predefined exception ZERO_DIVIDE, the execution of the block is interrupted, and control is transferred to the exception handlers.

Follow Steven Feuerstein / 7.14.2010 at 9:01pm A PL/SQL developer just sent me the following question: "I can't understand the difference between RAISE_APPLICATION_ERROR and RAISE. Why would I use one vs. the other?" Instead of answering via an email to just one developer, I thought I might share my answer with everyone. The RAISE_APPLICATION_ERROR built-in (defined in the DBMS_STANDARD package) should be used for just a single scenario: you need to communicate an application-specific error back to the user. Suppose, for example, I have a rule for the employees table that the minimum salary allowed is $100,000 (ah, wouldn't that be nice?). I want to enforce that rule through a database trigger: TRIGGER employees_minsal_tr BEFORE INSERT OR UPDATE ON employees FOR EACH ROWBEGIN IF :new.salary < 100000 THEN /* communicate error */ NULL; END IF;END; I can stop the DML from completing by issuing a RAISE statement, such as: RAISE PROGRAM_ERROR; But I would not be able to communicate back to the user what the actual problem was. If, on the other hand, I use RAISE_APPLICATION_ERROR, I can specify the error number (of little interest to my users, but a good "identifier" for support) and, more importantly, the error message, as in: TRIGGER emp
