How PL/SQL Exceptions Are Raised How PL/SQL Exceptions Propagate Reraising a PL/SQL Exception Handling Raised PL/SQL Exceptions Overview of PL/SQL Compile-Time Warnings Overview of PL/SQL Runtime Error Handling In PL/SQL, an error condition is called an exception. Exceptions can be internally defined (by the runtime system) or user defined. Examples of internally defined exceptions include division by zero oracle raise no_data_found 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 resumes with the next statement. If there is no enclosing block, control returns to the host environment.

tips Oracle Database Tips by Burleson Consulting March 3, 2015 Question: What does the PL/SQL raise_application_error code do? Answer: oracle user defined exception code range 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 https://docs.oracle.com/cd/B19306_01/appdev.102/b14261/errors.htm 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 http://www.dba-oracle.com/t_raise_application_error.htm 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'.

What is the WHEN OTHERS clause in Oracle? The WHEN OTHERS clause is used to trap all remaining exceptions that have not been handled by your Named System Exceptions and Named Programmer-Defined Exceptions. Syntax We user defined exception will take a look at the syntax for the WHEN OTHERS clause in both procedures and functions. Syntax for Procedures The syntax for the WHEN OTHERS clause in a procedure is: CREATE [OR REPLACE] PROCEDURE procedure_name [ (parameter [,parameter]) ] IS [declaration_section] BEGIN executable_section EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [procedure_name]; Syntax for Functions The syntax for the WHEN OTHERS clause in a function is: CREATE [OR REPLACE] FUNCTION function_name [ (parameter [,parameter]) ] RETURN return_datatype IS | AS [declaration_section] BEGIN executable_section EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [function_name]; Example Here is an example of a procedure that uses a WHEN OTHERS clause: 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,
is. It is an abomination of hard-coding and poor practice. If you didn't know that, I'm sorry I was the one who told you. I've written and used extensively an ultra-simple framework to eliminate RAISE_APPLICATION_ERROR from my code forever.Here's an example (assume 11gR2) of something we all know we can do:begin dbms_output.put_line(1/0); end;This will throw an unhandled ORA-01476 exception. We could write some meaningful handling of that with this:begin dbms_output.put_line(1/0);exception when zero_divide then dbms_output.put_line('zero divide exception caught');end;This coding is elegant because Oracle has conveniently predefined an exception named ZERO_DIVIDE and a corresponding pragma for us. Unfortunately, Oracle has only 22 predefined exceptions. What happens when I do this:declare d date;begin d := to_date('2010-09-30', 'YYYY-MM-DD'); -- works dbms_output.put_line(d); d := to_date('12345-09-30', 'YYYY-MM-DD'); -- fails dbms_output.put_line(d);end;This will throw an unhandled ORA-01861 exception. My option to handle this is less than meaningful because this is not a predefined exception:declare d date;begin d := to_date('2010-09-30', 'YYYY-MM-DD'); -- works dbms_output.put_line(d); d := to_date('12345-09-30', 'YYYY-MM-DD'); -- fails dbms_output.put_line(d);exception when others then case sqlcode when -1861 then dbms_output.put_line('literal does not match exception caught'); else raise; end case;end;This leads me to the inevitable desire to create my own named exception and pragma, so I could have code that looks like this instead:declare d date;begin d := to_date('2010-09-30', 'YYYY-MM-DD'); -- works dbms_output.put_line(d); d := to_date('12345-09-30', 'YYYY-MM-DD'); -- fails dbms_output.put_line(d);exception when error.ora_literal_string_mismatch then dbms_output.put_line('literal does not match exception caught');end;Understanding this, creating my own ERROR package with a friendly named exception and pragma for ORA-01861 leads me to the pattern of how to handle my own application exceptions, namely defining an exception and pragma. But how does this get RAISE_APPLICATION_ERROR out of my life?
