Oracle User Defined Exception Code Range
User-Defined Exception With Custom SQLERRM up vote 45 down vote favorite 21 Is it possible to create user-defined exceptions and be able to change the SQLERRM? For example: DECLARE ex_custom EXCEPTION; BEGIN RAISE ex_custom; EXCEPTION WHEN ex_custom THEN DBMS_OUTPUT.PUT_LINE(SQLERRM); END; / The output is "User-Defined Exception". Is it possible to change that message? EDIT: Here is some more detail. I hope this one illustrates what exception part can be defined twice in same block I'm trying to do better. DECLARE l_table_status VARCHAR2(8); l_index_status VARCHAR2(8); l_table_name VARCHAR2(30) := 'TEST'; l_index_name VARCHAR2(30) := 'IDX_TEST'; ex_no_metadata EXCEPTION; BEGIN BEGIN SELECT STATUS INTO l_table_status FROM USER_TABLES WHERE TABLE_NAME = l_table_name; EXCEPTION WHEN NO_DATA_FOUND THEN -- raise exception here with message saying -- "Table metadata does not exist." RAISE ex_no_metadata; END; BEGIN SELECT STATUS INTO l_index_status FROM USER_INDEXES WHERE INDEX_NAME = l_index_name; EXCEPTION WHEN NO_DATA_FOUND THEN -- raise exception here with message saying -- "Index metadata does not exist." RAISE ex_no_metadata; END; EXCEPTION WHEN ex_no_metadata THEN DBMS_OUTPUT.PUT_LINE('Exception will be handled by handle_no_metadata_exception(SQLERRM) procedure here.'); DBMS_OUTPUT.PUT_LINE(SQLERRM); END; / In reality, there are dozens of those sub-blocks. I'm wondering if there's a way to have a single user-defined exception for each of those sub-blocks to raise, but have it give a different message, instead of creating a separate user-defined exception for each sub-block. In .NET, it would be sort of like having a custom exception like this: public class ColorException : Exception { public ColorException(string message) : base(message) { } } And then, a method would have something like this: if (isRed) { throw new ColorException("Red is not allowed!"); } if (isBlack) { throw new

Oracle Raise Exception In Trigger
Asked Hi Tom, I am in the process of designing an error handling and failure notification system raise without exception name oracle for use by our all our custom PL/SQL programs. My plan is that all our custom PL/SQL programs, in the case of a fatal error, will call a http://stackoverflow.com/questions/6020450/oracle-pl-sql-raise-user-defined-exception-with-custom-sqlerrm single error handling procedure from within it's "WHEN OTHERS" exception clause. The intent is that we will have a centralized, standard, efficient error handling system, particularly an error notification system whereby the appropriate people will automatically be notified in case their program fails. This error handling procedure will receive parameters such as: calling program, sqlerrm, key variable https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:4684561825338 values at time of error, etc. The error handling procedure will then send an e-mail notification to the appropriate person (based on the program that failed), write a formatted error messege to the appropriate location based on the failed program, and bail out. I have some questions, please regarding this. 1. Do you like this idea philosophically and practically (i.e. having a centralized error handling and notification procedure/system) ? if not why? 2. I am concerned that by calling a procedure inside the exception clause, even though I am passing the current error info (sqlerrm, sqlcode)... I am afraid I may be losing some error info or masking some error info. I am wondering if I am losing anything by not dumping the original error immediatly, while it is 'fresh', instead of passing the 'sqlerrm' to another procedure... is this a valid concern ? why or why not ? 3. Can I count on 'format_error_stack' to give me the failing program's error or should I insist they pa

What oracle raise is a named programmer-defined exception in Oracle? Sometimes, it is necessary for programmers to name and 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 user defined exception 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_new_order (order_id_in IN NUMBER, sales_in IN NUMBER) IS no_sales EXCEPTION; BEGIN IF sales_in = 0 THEN RAISE no_sales; ELSE INSERT INTO orders (order_id, total_sales ) VALUES ( order_id_in, sales_in ); END IF; EXCEPTION WHEN no_sales THEN raise_application_error (-20001,'You must have sales in order to submit the order.'); WHEN OTHERS THEN raise_application_error (-20002,'An error has occurred inserting an order.'); END; In this example, we have declared a Named Programmer-Defined Exception called no_sales in our declaration statement with the following code: no_sales EXCEPTION; We've then raised the exception in the executable section of the code: IF sales_in = 0 THEN RAISE no_

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'.
