raise application error oracle example RAISE_APPLICATION_ERROR tips Oracle Database Tips by Burleson difference between raise and raise_application_error in oracle 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 byRaise_application_error(-20001
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
Oracle Raise
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 pragma exception_init and raise application error (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'.

Raise Application Error Oracle Forms
where in I drop partitions every day and add partitions. My question is about the raise_application_error parameters exception section. Do I have to give specific exception conditions to handle the erros which are possible while dropping and adding partitions, or raise application error in oracle triggers should I leave it by just giving the when others then exception, or should I leave it alone by not giving the exception section at all. what are the possible erros which can occur while trying to create http://www.dba-oracle.com/t_raise_application_error.htm a partition and trying to drop a partition. 2. The use of pragma exception init is very clear, but Why do you have to use a raise application error. Can I just use a regular exception, and raise it when I require to. I dont see the specific use of raise application error. what is the advantage of raise application error over a regular exception which you declare in the exception section and use it. (the https://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:1155066278457 only advantage seems to be that you can assign a number(20001 to 20999) to the error.) correct me if Iam wrong. and we said... 1) A when others is almost always a BUG unless it is immediately followed by a RAISE. The point of an exception block is to catch exceptional conditions you are EXPECTING, handle them gracefully and continue. For example, lets say you have a procedure that will either INSERT a new record or UPDATE an existing one depending on whether or not it exists. You could code: begin insert into t ( columns.... ) values ( values ..... ); exception when dup_val_on_index then -- record already exists, lets update it update t set .... = .... where ....; end; Now, if that was coded: begin insert into t ( columns.... ) values ( values ..... ); exception when dup_val_on_index then -- record already exists, lets update it update t set .... = .... where ....; when others then null; end; that would be a bug. The when others would fire upon some spurious -- un-expected error and the record would be neither added nor updated. It would be skipped. Same with your routines, if you have a when others -- and don't do anything meaningful in it (eg: email yourself a notification that it failed, log a message using utl_file or an autonomous transaction

Solved Raise Application Error Exception from After UPDATE Trigger Posted on 2002-11-13 Oracle Database 1 Verified Solution raise application 9 Comments 3,257 Views Last Modified: 2013-12-12 Hello, I'm using Oracle 7.34 for this. I want to just inform the user when a certain kind of UPDATE occured in Oracle. They will be making the changes in Access forms so I figured by calling RAISE_APPLICATION_ERROR as an exception AFTER the data has been changed in a trigger, then the user will see the raise application error message AND the UPDATE will also occur. The info message is currently displaying but the UPDATE is NOT occuring. Why is this? I put this exception in an AFTER UPDATE trigger for the sole purpose that the UPDATE would happen first then the trigger would fire this message. If this method cannot work, how else can I inform a user from Oracle that an UPDATE just occured in a similiar way that the RAISE_APPLICATION_ERROR formats the message?

Exceptions are not intended to return a message to the caller! There is no easy way i can think of t
