Raise_application_error Error Codes


Example 10-1 Runtime Error Handling DECLARE stock_price NUMBER := 9.73; net_earnings NUMBER := 0; pe_ratio NUMBER; BEGIN -- Calculation might cause division-by-zero error. LOGIN_DENIED 01017 -1017 A program attempts to log on to Oracle with an invalid username or password. sal_high EXCEPTION; 5. To give a name to an internally defined exception, do the following in the declarative part of the appropriate anonymous block, subprogram, or package. (To determine the appropriate block, see "Exception click site

raise_application_error(-20101, 'User ' || in_user || ' already exists!'); Now your application code can write an exception handler in order to process this specific error condition. Burleson Consulting The Oracle of Database Support Oracle Performance Tuning Remote DBA Services Copyright © 1996 - 2016 All rights reserved by Burleson Oracle is the registered trademark of Example 11-5 gives the name deadlock_detected to the internally defined exception ORA-00060 (deadlock detected while waiting for resource) and uses the name in an exception handler. If you neglect to code a check, the error goes undetected and is likely to cause other, seemingly unrelated errors.

Raise Application Error Oracle Example

For example, PL/SQL raises the predefined exception NO_DATA_FOUND if a SELECT INTO statement returns no rows. User-defined exceptions must be raised explicitly by RAISE statements or invocations of the procedure DBMS_STANDARD.RAISE_APPLICATION_ERROR. Recompile procedure: ALTER PROCEDURE unreachable_code COMPILE; Result: SP2-0805: Procedure altered with compilation warnings Show errors: SHOW ERRORS Result: Errors for PROCEDURE UNREACHABLE_CODE: LINE/COL ERROR -------- ----------------------------------------------------------------- 7/5 PLW-06002: Unreachable code DBMS_WARNING Example 11-16 Exception Raised in Declaration is Handled by Enclosing Block BEGIN DECLARE credit_limit CONSTANT NUMBER(3) := 5000; BEGIN NULL; END; EXCEPTION WHEN VALUE_ERROR THEN DBMS_OUTPUT.PUT_LINE('Exception raised in declaration.'); END; /

For information about managing errors when using BULK COLLECT, see Handling FORALL Exceptions (%BULK_EXCEPTIONS Attribute). Place the statement in its own sub-block with its own exception handlers. You can also set it for a single compilation by including it as part of the ALTER PROCEDURE ... Oracle Raise INVALID_CURSOR 01001 -1001 A program attempts a cursor operation that is not allowed, such as closing an unopened cursor.

Retrieving the Error Code and Error Message: SQLCODE and SQLERRM In an exception handler, you can use the built-in functions SQLCODE and SQLERRM to find out which error occurred and to Raise_application_error Syntax Advantages of PL/SQL Exceptions Using exceptions for error handling has several advantages. From there on, the exception propagates normally. INVALID_NUMBER 01722 -1722 n a SQL statement, the conversion of a character string into a number fails because the string does not represent a valid number. (In procedural statements, VALUE_ERROR is

That way, an exception handler written for the predefined exception can process other errors, as Example 10-7 shows: Example 10-7 Using RAISE to Force a Pre-Defined Exception DECLARE acct_type INTEGER := Pragma Exception_init And Raise Application Error 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 usual scoping rules for PL/SQL variables apply, so you can reference local and global variables in an exception handler. The following link provides lots of good information on this topic and Oracle exceptions in general.

Raise_application_error Syntax

The message begins with the Oracle error code. Redeclaring predefined exceptions is error prone because your local declaration overrides the global declaration. Raise Application Error Oracle Example The runtime system raises them implicitly (automatically). Difference Between Raise And Raise_application_error In Oracle STORAGE_ERROR PL/SQL runs out of memory or memory has been corrupted.

You can also check for errors in a single statement by putting that statement inside a block with its own exception handler. get redirected here Raising Internally Defined Exception with RAISE Statement Although the runtime system raises internally defined exceptions implicitly, you can raise them explicitly with the RAISE statement if they have names. EXCEPTION WHEN NO_DATA_FOUND THEN -- catches all 'no data found' errors Exceptions improve readability by letting you isolate error-handling routines. In that case, we change the value that needs to be unique and continue with the next loop iteration. Raise_application_error(-20001

In such cases, you must use dot notation to specify the predefined exception, as follows: EXCEPTION WHEN invalid_number OR STANDARD.INVALID_NUMBER THEN -- handle the error END; How PL/SQL Exceptions Are Raised That is, the exception reproduces itself in successive enclosing blocks until either a block has a handler for it or there is no enclosing block. For internal exceptions, SQLCODE returns the number of the Oracle error. http://vealcine.com/raise-application/raise-application-error-error-codes-range.php by Steven Feuerstein on 28 Nov 2012 0 comments View More RAISE vs RAISE_APPLICATION_ERROR?

A cursor FOR loop automatically opens the cursor to which it refers. Raise_application_error Parameters In Example 11-6, you alert your PL/SQL block to a user-defined exception named out_of_stock. CASE_NOT_FOUND None of the choices in the WHEN clauses of a CASE statement is selected, and there is no ELSE clause.

Passing the value of 'True' adds the error to the current stack, while the default is 'False'.

SET SERVEROUTPUT ON SIZE 200000 2. User-defined You can declare your own exceptions in the declarative part of any PL/SQL anonymous block, subprogram, or package. With PL/SQL, a mechanism called exception handling lets you bulletproof your program so that it can continue operating in the presence of errors. Raise Application Error In Oracle Triggers For example, the declaration in Example 11-10 raises an exception because the constant credit_limit cannot store numbers larger than 999.

raise_application_error(-20001,'Salary is high'); 10. For example, if you know that the warning message PLW-05003 represents a serious problem in your code, including 'ERROR:05003' in the PLSQL_WARNINGS setting makes that condition trigger an error message (PLS_05003) The error_code is an integer in the range -20000..-20999 and the message is a character string of at most 2048 bytes. my review here In Example 11-10, the procedure raises the predefined exception INVALID_NUMBER either explicitly or implicitly, and the INVALID_NUMBER exception handler always handles it.

WHEN ZERO_DIVIDE THEN -- handles 'division by zero' error DBMS_OUTPUT.PUT_LINE('Company must have had zero earnings.'); pe_ratio := NULL; WHEN OTHERS THEN -- handles all other errors DBMS_OUTPUT.PUT_LINE('Some other kind of error Tip: Avoid unhandled exceptions by including an OTHERS exception handler at the top level of every PL/SQL program. Example 11-5 Naming Internally Defined Exception DECLARE deadlock_detected EXCEPTION; PRAGMA EXCEPTION_INIT(deadlock_detected, -60); BEGIN ... DECLARE pe_ratio NUMBER(3,1); BEGIN SELECT price / earnings INTO pe_ratio FROM stocks WHERE symbol = 'XYZ'; -- might cause division-by-zero error INSERT INTO stats (symbol, ratio) VALUES ('XYZ', pe_ratio); COMMIT; EXCEPTION

Add exception handlers wherever errors can occur. TIMEOUT_ON_RESOURCE A time-out occurs while Oracle is waiting for a resource. Unix Exit Command When your mind reviews past events About a man and a bee Why generic lambdas are allowed while nested structs with templated methods aren't? Next, the example enables all warnings for the session by invoking DBMS_WARNING.set_warning_setting_string and displays the value of PLSQL_WARNINGS by invoking DBMS_WARNING.get_warning_setting_string.

RAISE_APPLICATION_ERROR is part of package DBMS_STANDARD, and as with package STANDARD, you do not need to qualify references to it. To call RAISE_APPLICATION_ERROR, use the syntax raise_application_error( error_number, message[, {TRUE | FALSE}]); where error_number is a negative integer in the range -20000 .. -20999 and message is a character string up However, an exception name can appear only once in the exception-handling part of a PL/SQL block or subprogram. 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.

Errors are especially likely during arithmetic calculations, string manipulation, and database operations. If an error occurs in the sub-block, a local handler can catch the exception. pe_ratio := stock_price / net_earnings; DBMS_OUTPUT.PUT_LINE('Price/earnings ratio = ' || pe_ratio); EXCEPTION -- exception handlers begin -- Only one of the WHEN blocks is executed. After the exception handler runs, control transfers to the host environment.

SELECT salary INTO l_n_salary FROM employees WHERE employee_id=:employee_id; 8. If there is no enclosing block, then: If the exception handler is in a subprogram, then control returns to the invoker, at the statement after the invocation. Example 11-9 Declaring, Raising, and Handling User-Defined Exception CREATE PROCEDURE account_status ( due_date DATE, today DATE ) AUTHID DEFINER IS past_due EXCEPTION; -- declare exception BEGIN IF due_date < today THEN If you want two or more exceptions to execute the same sequence of statements, list the exception names in the WHEN clause, separating them by the keyword OR, as follows: EXCEPTION

You code the pragma EXCEPTION_INIT in the declarative part of a PL/SQL block, subprogram, or package using the following syntax: PRAGMA EXCEPTION_INIT(exception_name, -Oracle_error_number); where exception_name is the name of a The technique is: Encase the transaction in a sub-block. If ex_name_1 was raised, then statements_1 run. asked 6 years ago viewed 79662 times active 6 years ago Blog Stack Overflow Podcast #92 - The Guerilla Guide to Interviewing Visit Chat Related 723Get list of all tables in
