SQL> SQL> INSERT INTO EMP VALUES (7369, 'SMITH', 'CLERK', 7902, TO_DATE('17-DEC-1980', 'DD-MON-YYYY'), 800, NULL, 20); 1 row created. Statement based triggers should not see a Mutating Table error from Oracle. Make a standalone procedure that uses Autonomous transaction. It could represent a mistake, or it could be intentionally hidden by a debug flag, so you might or might not want a warning message for it.
SQL> SQL> SQL> CREATE OR REPLACE TRIGGER secure_del_trigger 2 BEFORE DELETE 3 ON emp 4 FOR EACH ROW 5 DECLARE 6 unauthorized_deletion EXCEPTION; 7 BEGIN 8 IF 1 = 1 9 You can save the current state of the PLSQL_WARNINGS parameter with one call to the package, change the parameter to compile a particular set of subprograms, then restore the original parameter Oracle gives up in a Mutating Table situation. Internal exceptions are raised implicitly (automatically) by the run-time system.
In the below example, the employee, whose salary is more than 10000 will be facing an exception which is handled explicitly in the WHEN clause using the user defined exception name. Because this exception is used internally by some SQL functions to signal completion, you should not rely on this exception being propagated if you raise it within a function that is Instead Of Triggers only work on Views (not on tables). Instead, you must assign their values to local variables, then use the variables in the SQL statement, as shown in Example 10-11.
If you recompile the subprogram with a CREATE OR REPLACE statement, the current settings for that session are used. This procedure accepts an integer (your error code), whose value must be between -20,999 and -20,000, and a string (your error message). 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). This the output, any help ?
WHEN NO_DATA_FOUND THEN Catch either the NO_DATA_FOUND or DUP_VAL_ON_INDEX predefined exceptions. Exception Overview There are three categories of exceptions in the world of PL/SQL: internally defined, predefined, and user-defined. Code Listing 1: Exception handling section inserting into log table EXCEPTION WHEN OTHERS THEN DECLARE l_code INTEGER := SQLCODE; BEGIN INSERT INTO error_log (error_code , error_message , backtrace , callstack , DBMS_OUTPUT.PUT_LINE('Can''t handle an exception in a declaration.'); END; / Handlers in the current block cannot catch the raised exception because an exception raised in a declaration propagates immediately to the enclosing

Instead Of Triggers First of all, this capability is only supported on the Enterprise Edition of Release 8.1.5 of Oracle 8i. Every exception has an error code and an error message associated with it.
I know that this table is different from the “real” tables of the application (for example, the Employees table of the human resources application). see here However, other user-defined exceptions must be raised explicitly by RAISE statements. SQL> @8b Trigger created. I can now very easily get around the problem of rolling back my error log INSERT along with my business transaction.
Suppose I run the following block in a SQL*Plus session: BEGIN DELETE FROM employees WHERE department_id = 20; UPDATE employees SET salary = salary * 200; EXCEPTION WHEN OTHERS THEN DECLARE 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 You can lead some folks to knowledge, but you can not make them think. this page yogesh Oct 12, 2010 11:06 AMCorrect AnswerMay be you can write a stored procedure to raise the application error and then call it in the GEL script.
SQLERRM or DBMS_UTILITY.FORMAT_ERROR_STACK Note: You cannot call SQLERRM inside a SQL statement. It contains a carefully constructed set of problems and solutions that will test your language skills and help you become a better developer--both with PL/SQL and with other languages. You can make the checking as general or as precise as you like.
You can define exceptions of your own in the declarative part of any PL/SQL block, subprogram, or package.
Description How to Get It The error code. For a workaround, see "Defining Your Own Error Messages: Procedure RAISE_APPLICATION_ERROR". The beauty of this design is that all exception-related activity is concentrated in one area in the PL/SQL block, making it easy for developers to understand and maintain all error management In the next chapter we will cover other Events which can call Triggers such as Login, Logoff, Create, Drop, or Alter.
We need to know this URGENTLY!! SQL> INSERT INTO EMP VALUES (7934, 'MILLER', 'CLERK', 7782,TO_DATE('23-JAN-1982', 'DD-MON-YYYY'), 1300, NULL, 10); 1 row created. Oracle Database makes it easy to do this with the RAISE statement. Get More Info With PL/SQL, a mechanism called exception handling lets you bulletproof your program so that it can continue operating in the presence of errors.
Experience comes from bad judgement. If a rollback is performed because of the error, the INSERT into the log table will also be rolled back. I don't have a lot of details but It's worth looking into it... That is, the exception reproduces itself in successive enclosing blocks until a handler is found or there are no more blocks to search.
How about you found out that you updated a bunch of things and found out that the data wasn't available, because some trigger that you weren't aware of decided to rollback Tips for Handling PL/SQL Errors In this section, you learn techniques that increase flexibility. The error message. A trigger that forbids updates to EMP during Non-Business Hours CREATE OR REPLACE TRIGGER secure_emp BEFORE UPDATE ON emp BEGIN IF (TO_CHAR (sysdate,'DY') IN ('SAT','SUN')) OR (TO_CHAR(sysdate,'HH24') NOT BETWEEN '08' AND
