An exception can be either internally defined (by the

run-time system) or user-defined. Examples of internally defined exceptions are ORA-22056 (value string is divided by zero) and ORA-27102 (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 your own exceptions in the declarative part of any PL/SQL block, subprogram, or package. For pragma exception_init and raise application error example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. 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 or invocations of the procedure DBMS_STANDARD.RAISE_APPLICATION_ERROR. 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 about managing errors when using BULK COLLECT, see Handling FORALL Exceptions (%BULK_EXCEPTIONS Attribute). Example 11-1 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 no

Raise Application Error In Oracle Triggers
RAISE_APPLICATION_ERROR tips Oracle Database Tips by Burleson Consulting March 3, 2015 Question: What does the
Raise_application_error Error Number Range
PL/SQL raise_application_error code do? Answer: 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 https://docs.oracle.com/cd/B28359_01/appdev.111/b28370/errors.htm the procedure. This allows the application 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 http://www.dba-oracle.com/t_raise_application_error.htm 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 (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'.

Join them; it only takes a minute: Sign up raise_application_error exception handling in subprocedures up vote 1 down vote favorite I have multiple stored procedures calling multiple stored procedures in raise application my database. To give a small example, I've constructed a fictionalised version of a few of them below. In my example, a Java program calls calculate_bill, which calls calculate_commission, which calls update_record. I'm hoping to get some advice on how best to propagate the error messages up the stack to the calling Java layer, so the user gets a precise error message corresponding to wherever the error has occurred. I'm really quite stuck raise application error on this. I've played around in my example with raise_application_error and just continually shuffling it up the stack. Is the way I'm doing it below remotely correct? Or is one raise_application_error in the relevant procedure enough, with no pragma exception init etc needed? To give an idea of what I mean, in the example below, if a user entered a number which corresponded to a record which couldn't be updated because it didn't exist, I'd like them to get the message: "Error calculating bill. Error calculating commission. No record exists to be updated" or something to that effect. So two questions: What is the best practice, most efficient, most tidy way to pass error messages up the stack for the end user in the application layer? Does anyone have any suggestions on tidier output from the code, i.e. the best way to concatenate these errors to make them more meaningful? I'm really open to any suggestions on how to make this work best as I have absolutely no prior experience in this. Example: (Error in code): -20000 : Error in top level procedure -20001 : Error in middle level procedure -20002 : Error in bottom level procedure Java code: try { // call calculate_bill exception (SQLException ex) // output oracle code and relevant message.

is used in Raise_application_error? [message #244255] Tue, 12 June 2007 03:10 orafacjublu Messages: 95Registered: May 2006 Location: KOLKATA Member From the oracle document I found that Raise_application_error can take a third argument TRUE/FALSE .If it is true then it gets into the error stack. Can anyone kindly elaborate me what exactly gets stored in the stack; whether the stack is a data-dictionary table or view ? pls clear. Kindly give me an example of the real life application of using raise_application_error with the true argument eg. raise_application_error(-20000,message_text,TRUE) Report message to a moderator Re: Why true argument is used in Raise_application_error?
