Difference Between Raise And Raise_application_error In Oracle
PL/SQL Run-Time Error Handling In PL/SQL, an error condition is called an exception. An exception can be either internally defined (by the run-time system) or user-defined. Examples of internally defined exceptions are
Oracle Predefined Exceptions
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 example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. User-defined exceptions oracle sqlerrm 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 not name specifically. Example 11-1 Run-Time Error Handling DECLARE stock_price NUMBER := 9.73; net_earnings NUMBER := 0; pe_ratio NUMBER; BEGIN -- Calculation might cause division-by-zero error. pe_ratio := stock_price / net_earnings; DBMS_OUTPUT.PUT

RAISE_APPLICATION_ERROR tips Oracle raise application error in oracle triggers tips by Burleson March 3, 2015 Question: What does the PL/SQL raise_application_error code do? Answer: The raise_application_error is actually a procedure defined by Oracle that https://docs.oracle.com/cd/B28359_01/appdev.111/b28370/errors.htm 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 are defined between -20,000 and -20,999. Oracle provides the raise_application_error procedure to allow you to raise custom error numbers within http://www.dba-oracle.com/t_raise_application_error.htm 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 (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 thehere for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings http://stackoverflow.com/questions/36295233/raise-application-error-oracle and policies of this site About Us Learn more about Stack Overflow the company Business Learn more about hiring developers or posting ads with us Stack Overflow Questions Jobs Documentation Tags https://books.google.com/books?id=xIAxulfhCHUC&pg=PA374&lpg=PA374&dq=application+error+read+oracle&source=bl&ots=t2aBfQGB6x&sig=2K6o2Uc1OdoOjwYEv8pdZsZbZz8&hl=en&sa=X&ved=0ahUKEwj9xIO0vKzPAhVlxYMKHdarCTgQ6AEIUjAI Users Badges Ask Question x Dismiss Join the Stack Overflow Community Stack Overflow is a community of 4.7 million programmers, just like you, helping each other. Join them; it only in oracle takes a minute: Sign up Raise Application Error - Oracle up vote 1 down vote favorite I have a question regarding the error codes (-20000 to -20999) for Raise Application Error. Can we use same error code (eg -20000) only for different error scenarios at multiple places in PLSQL code? If we can use same error code in all places, error in oracle why do we have 1000 codes? What is the best practice to use error codes in Raise Application Error? Sample Code: CREATE TABLE T(ID NUMBER PRIMARY KEY); Declare begin Insert into t(id) values (1); Insert into t(id) values (1); commit; EXCEPTION When Dup_val_on_index then Raise_application_error(-20000,'Cannot Insert duplicates'); WHEN OTHERS THEN Raise_application_error(-20000,SQLCODE||'-'||SQLERRM); end; Thanks Abhi oracle share|improve this question asked Mar 29 at 21:16 Abhi 111 add a comment| 4 Answers 4 active oldest votes up vote 3 down vote Can we use same error code (eg -20000) only for different error scenarios at multiple places in PLSQL code? As Justin notes, you can certainly do that - just use one code. But it is likely to lead to confusion. I've seen it done, and usually in that case, the developers simply embed all critical information into the message, even including a code (they might, for example, already be using their own error codes that fall outside the acceptable range). I suggest you follow Oracle's lead: assign ranges to areas of your application and then use error codes within a ra
