Raise Application Error 20500
to your PL/SQL program. 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 PL/SQL, a mechanism called exception handling lets you bulletproof your program so that it can continue operating in the presence of errors. This chapter contains these topics: Overview of PL/SQL Runtime Error Handling Advantages of PL/SQL Exceptions Summary of Predefined PL/SQL Exceptions Defining Your Own PL/SQL Exceptions 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 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.

Now, for example, if a column "email" has no '@' in it, the trigger should report an error. But I also want to show a log of all user errors so I can keep a track. This is how I did it: CREATE SEQUENCE counter INCREMENT BY 1 START WITH 1 NOCACHE NOCYCLE; CREATE TABLE log_errors(id number PRIMARY KEY, table_name varchar2(30) NOT NULL, operation varchar2(30) NOT NULL, column_name varchar2(30) http://www.dbforums.com/showthread.php?1657077-RAISE_APPLICATION_ERROR-problem NOT NULL, row_name varchar2(30) NOT NULL, error_log varchar2(30) NOT NULL, user_error varchar2(30) NOT NULL, date_error date NOT NULL); CREATE OR REPLACE TRIGGER validation_table AFTER INSERT ON table_name REFERENCING OLD AS OLD NEW AS NEW FOR EACH ROW begin if :new.email NOT LIKE '%@%' then INSERT INTO log_errors VALUES( counter.nextval, 'Table', 'Insert', 'email', :new.email, 'Adress has no @', user, sysdate); RAISE_APPLICATION_ERROR (-20500, ''Adress has no @.'); end if; end; The problem is, when I insert a row with bad email, the RAISE_APPLICATION_ERROR error log shows, but the insert into log table never hapens. Why? Does anyone here have a solution? Thanks in advance. Last edited by kamion; 06-02-10 at 12:18.

Just curious, when does COMMIT occur? You can lead some folks to knowledge, but you can not make them think. The average person thinks he's above average! For most folks, they don't know, what they don't know. Good judgement comes from experience. Experience comes from bad judgement.

From the Docs, In a BEFORE statement trigger, the trigger body cannot read :NEW or :OLD. (In a BEFORE row trigger, the trigger body can read and write the :OLD and :NEW fields.) So like this CREATE OR REPLACE TRIGGER orders_before_insert BEFORE INSERT ON student FOR EACH ROW share|improve this answer answered Apr 20 at 19:23 cableload 2,58411833 THANK YOOOOOOOOOOOOOOOOOOOOU !!!!!!! –Independent Apr 20 at 19:29 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.
