With many programming languages, unless you disable error checking, a run-time error such as stack overflow or division by zero stops normal processing and returns control to the operating system. With raise_application_error(-20001 PL/SQL, a mechanism called exception handling lets you bulletproof your program so that it

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 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 write query in sql for updating data in table 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. For information on managing errors when using BULK COLLECT, see "Handling FORALL Exceptions with the %BULK_EXCEPTIONS Attribute". Example 10-1 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. The optional OTHERS handler catches all exceptions that the block does not name specifically. Example 10-1 Runtime Error Handling DECLARE stock_price NUMBER := 9.73; net_earnings NUMBER := 0; pe_ratio NUMBER; BEGIN -- Calcu

The first is to replace generic Oracle exception messages with our own, more meaningful messages. The second is to create exception conditions of our own, when Oracle would not throw them. The following procedure illustrates both usages. It enforces a business rule that new employees cannot be hired in the future. It also overrides two Oracle exceptions. One is DUP_VAL_ON_INDEX, which is thrown by a unique key on EMP(ENAME). The other is a a user-defined exception thrown when the foreign key between EMP(MGR) and EMP(EMPNO) is violated (because a manager must be an existing employee). create or replace procedure new_emp ( p_name in emp.ename%type , p_sal in emp.sal%type , p_job in emp.job%type , p_dept in emp.deptno%type , p_mgr in emp.mgr%type , p_hired in emp.hiredate%type := sysdate ) is invalid_manager exception; PRAGMA EXCEPTION_INIT(invalid_manager, -2291); dummy varchar2(1); begin -- check hiredate is valid if trunc(p_hired) > trunc(sysdate) then raise_application_error (-20000 , 'NEW_EMP::hiredate cannot be in the future'); end if; insert into emp ( ename , sal , job , deptno , mgr , hiredate ) values ( p_name , p_sal , p_job , p_dept , p_mgr , trunc(p_hired) ); exception when dup_val_on_index then raise_application_error (-

What 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 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 ca
