RAISE_APPLICATION_ERROR tips Oracle raise_application_error(-20001 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 oracle raise 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 ratherRaise_application_error Parameters
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 in oracle triggers 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'.

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_mana
