Exceptions can be internally defined (by the run-time system) or user defined. Examples of internally defined exceptions include division by zero and 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 exceptions of your own 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. Unlike internal exceptions, 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, which can also raise predefined exceptions.

How your code responds to and deals with that error often spells the difference between a oracle sql successful application and one that creates all sorts of problems for users as well as developers. This article explores the world of error management in PL/SQL: the different types of exceptions you may encounter; when, why, and how exceptions are raised; how to define your own exceptions; how you can handle exceptions when they occur; and how you can report information about problems back how to display to your users. Exception Overview There are three categories of exceptions in the world of PL/SQL: internally defined, predefined, and user-defined. An internally defined exception is one that is raised internally by an Oracle Database process; this kind of exception always has an error code but does not have a name unless it is assigned one by PL/SQL or your own code. An example of an internally defined exception is ORA-00060 (deadlock detected while waiting for resource). A predefined exception is an internally defined exception that is assigned a name by PL/SQL. Most predefined exceptions are defined in the STANDARD package (a package provided by Oracle Database that defines many common programming elements of the PL/SQL language) and are among the most commonly encountered exceptions. One example is ORA-00001, which is assigned the name DUP_VAL_ON_INDEX in PL/SQL and is raised when a unique index constraint is violated. A user-defined exception is one you have declared in the declaration section of a program unit. User-defined exceptions can be associated with an internally defined exception (that is, you can give a name to an otherwise unnamed exception) or with an application-specific er

For simplicitys sake in the code block below I am simply outputting the exception code and error message to the console. However, the code block below does not work (I am experiencing a "found / expecting" syntax error) CREATE OR REPLACE PROCEDURE DBP.TESTING_SP AS DECLARE v_code NUMBER; v_errm VARCHAR2(64); BEGIN UPDATE PS_NE_PHONE_TBL SET NE_PHONE_TYPE = 'TEST' WHERE NEMPLID_TBL = 'N14924'; EXCEPTION WHEN OTHERS THEN v_code := SQLCODE; v_errm := SUBSTR(SQLERRM, 1, 64); DBMS_OUTPUT.PUT_LINE (v_code || ' ' || v_errm); END TESTING_SP; / What is the correct syntax for what I am trying to do? I read on one forum "When using the Create or Replace syntax, you can not use Declare. Declare is only for anonymous blocks that are not named. So either remove line 1 and create an anonymous block, or remove line 2 and create a named procedure." but I'm not sure how to create an anonymous block or create a named procedure to accomplish what I want to do (if that, indeed, is the 'solution'). Could somebody lend a hand? oracle stored-procedures plsql share|improve this question edited Sep 8 '12 at 2:56 asked Sep 8 '12 at 2:48 n00b 1,26821544 Unless you are are doing something useful with the exception information, there is no need to catch it. The best way to pass exception information to the calling function is to do nothing, and let the exception naturally raise. This uses less code and preserves the real line number of the error. –Jon Heller Sep 8 '12 at 4:17 add a comment| 1 Answer 1 active oldest votes up vote 4 down vote accepted Just remove the DECLARE statement. share|improve this answer answered Sep 8 '12 at 3:01 DCookie 28.8k84765 aweso
