Raise Application Error Codes


To handle unexpected Oracle errors, you can use the OTHERS handler. turn translation off Search Clear Search Options Search Everything Search Oracle |LOGIN |REGISTER TRAININGToad Courseware Academic Program Training Courses DOWNLOADSFreeware & Trials PLATFORMSDatabase Blogs & Wikis IBM DB2 MySQL NoSQL Predefined PL/SQL Exceptions An internal exception is raised implicitly whenever your PL/SQL program violates an Oracle rule or exceeds a system-dependent limit. Continuing after an Exception Is Raised An exception handler lets you recover from an otherwise fatal error before exiting a block. http://vealcine.com/raise-application/raise-application-error-error-codes-range.php

Examples of internally defined exceptions include division by zero and out of memory. ORA-06512: at "A.TRG_EMP_DETAILL_CHK", line 4 ORA-04088: error during execution of trigger 'A.TRG_EMP_DETAILL_CHK' 20000. 00000 - "%s" *Cause: The stored procedure 'raise_application_error' was called which causes this error to be generated. If you find an error or have a suggestion for improving our content, we would appreciate your feedback. The maximum length of an Oracle error message is 512 characters including the error code, nested messages, and message inserts such as table and column names.

Raise_application_error Vs Raise

END; Handlers in the current block cannot catch the raised exception because an exception raised in a declaration propagates immediately to the enclosing block. 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 to Unlike variables, exceptions cannot appear in assignment statements or SQL statements. The other is a a user-defined exception thrown when the foreign key between EMP(MGR) and EMP(EMPNO) is violated (because a manager must be an existing employee).

If there is no enclosing block, control returns to the host environment. However, an exception name can appear only once in the exception-handling part of a PL/SQL block or subprogram. For a workaround, see "Defining Your Own Error Messages: Procedure RAISE_APPLICATION_ERROR". Raise_application_error Parameters share|improve this answer edited Nov 19 '09 at 10:39 answered Nov 19 '09 at 7:11 APC 87.4k1384184 +1 Very explanatory.

Redeclaring predefined exceptions is error prone because your local declaration overrides the global declaration. However, exceptions cannot propagate across remote procedure calls (RPCs). BEGIN 7. Execution of the handler is complete, so the sub-block terminates, and execution continues with the INSERT statement.

However, you can achieve the same paradigm with RAISE_APPLICATION_ERROR. Raise Application Error In Sql Server You code the pragma EXCEPTION_INIT in the declarative part of a PL/SQL block, subprogram, or package using the syntax PRAGMA EXCEPTION_INIT(exception_name, -Oracle_error_number); where exception_name is the name of a previously declared For example, if you declare an exception named invalid_number and then PL/SQL raises the predefined exception INVALID_NUMBER internally, a handler written for INVALID_NUMBER will not catch the internal exception. The error number and message can be trapped like any Oracle error.


SQL> SQL> SQL> SQL> SQL> CREATE OR REPLACE PROCEDURE org_proc 2 (p_flag_in VARCHAR2, 3 p_product_id NUMBER, 4 p_company_id NUMBER, 5 p_company_short_name VARCHAR2, 6 p_company_long_name VARCHAR2) 7 IS 8 v_error_code NUMBER; 9 Associating a PL/SQL Exception with a Number: Pragma EXCEPTION_INIT To handle error conditions (typically ORA- messages) that have no predefined name, you must use the OTHERS handler or the pragma EXCEPTION_INIT. Raise_application_error Vs Raise Consider the example below. Oracle Raise PL/SQL declares predefined exceptions globally in package STANDARD.

The third parameter is an optional one which accepts a Boolean value. get redirected here An application can call raise_application_error only from an executing stored subprogram (or method). END; Omitting the exception name in a RAISE statement--allowed only in an exception handler--reraises the current exception. Figure 10-1 Propagation Rules: Example 1 Description of the illustration lnpls009.gif Figure 10-2 Propagation Rules: Example 2 Description of the illustration lnpls010.gif Figure 10-3 Propagation Rules: Example 3 Description of the Pragma Exception_init And Raise Application Error

The functions SQLCODE and SQLERRM are especially useful in the OTHERS exception handler because they tell you which internal exception was raised. In the following example, you call raise_application_error if an employee's salary is missing: CREATE PROCEDURE raise_salary (emp_id NUMBER, amount NUMBER) AS curr_sal NUMBER; BEGIN SELECT sal INTO curr_sal FROM emp WHERE Suppose you used number constants instead of string constants to identify your exceptions and passed these to throw(). http://vealcine.com/raise-application/raise-application-error-error-codes.php The keyword OTHERS cannot appear in the list of exception names; it must appear by itself.

Description 1 This environment variable opens up an output buffer of size limit of 200000. 2 Start of the declaration section of the block. 3 A local variable l_n_salary of the Raise_application_error Number Range The "message" does not get raised for exceptions passed to throw() that are outside the RAISE_APPLICATION_ERROR range. Although you cannot anticipate all possible errors, you can plan to handle certain kinds of errors meaningful to your PL/SQL program.

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

Catching Unhandled Exceptions Remember, if it cannot find a handler for a raised exception, PL/SQL returns an unhandled exception error to the host environment, which determines the outcome. Sometimes the error is not immediately obvious, and could not be detected until later when you perform calculations using bad data. SELF_IS_NULL Your program attempts to call a MEMBER method on a null instance. Raise Application Error In Oracle Triggers Figure7-1, Figure7-2, and Figure7-3 illustrate the basic propagation rules.

That lets you refer to any internal exception by name and to write a specific handler for it. Why would I use one vs. So, an exception raised inside a handler propagates immediately to the enclosing block, which is searched to find a handler for the newly raised exception. my review here Without exception handling, every time you issue a command, you must check for execution errors: BEGIN SELECT ... -- check for 'no data found' error SELECT ... -- check for 'no

NO_DATA_FOUND A SELECT INTO statement returns no rows, or your program references a deleted element in a nested table or an uninitialized element in an index-by table. Verify experience! END IF; 11. The second is to create exception conditions of our own, when Oracle would not throw them.

But, according to the scope rules, enclosing blocks cannot reference exceptions declared in a sub-block. The raise_application_error will also populate the SQL errors codes so that they can be programmatically handled. ================================================== The built in procedure RAISE_APPLICATION_ERROR in the DBMS_STANDARD package can be used for displaying END IF; 9. CURSOR_ALREADY_OPEN 06511 -6511 A program attempts to open an already open cursor.

Isolating error-handling routines makes the rest of the program easier to read and understand. With exceptions, you can handle errors conveniently without the need to code multiple checks, as follows: BEGIN SELECT ... PL/SQL warning messages all use the prefix PLW. In the above example, a trigger has been created in the schema A to stop any modification to the EMPLOYEES table's data during the weekend.

The settings for the PLSQL_WARNINGS parameter are stored along with each compiled subprogram.
