Oracle User Defined Error Code Range
Contents |
Churchill Run-time errors arise from design faults, coding mistakes, hardware failures, and many other sources. Although you cannot anticipate all possible exception handling in oracle stored procedure example errors, you can plan to handle certain kinds of errors meaningful oracle raise exception with message to your PL/SQL program. With many programming languages, unless you disable error checking, a run-time error such oracle sqlerrm as stack overflow or division by zero stops normal processing and returns control to the operating system. With PL/SQL, a mechanism called exception handling lets you "bulletproof" your program

so that it can continue operating in the presence of errors. This chapter discusses the following topics: Overview of PL/SQL Error Handling Advantages of PL/SQL Exceptions Predefined PL/SQL Exceptions Defining Your Own PL/SQL Exceptions How PL/SQL Exceptions Are Raised How PL/SQL Exceptions Propagate Reraising a PL/SQL Exception Handling Raised PL/SQL Exceptions Tips for Handling PL/SQL Errors Overview of exception handling in oracle 11g example PL/SQL Error Handling In PL/SQL, a warning or error condition is called an exception. 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. To handle raised exceptions, you write separate routines called exception handlers. After an exception handler runs, the current block s

The USER_DUMP_DEST initialization parameter specifies the https://docs.oracle.com/cd/E11882_01/appdev.112/e25519/errors.htm current location of the trace files. You can find the value of this parameter by issuing SHOW PARAMETER USER_DUMP_DEST. For more information about trace files, see Oracle Database Performance Tuning Guide. Compile-Time Warnings While compiling stored PL/SQL units, the PL/SQL compiler generates warnings for conditions that are not serious enough to cause errors and prevent compilation—for example, using a deprecated PL/SQL feature. To see warnings (and errors) generated during compilation, either query the static data dictionary view *_ERRORS (described in Oracle Database Reference) or, in the SQL*Plus environment, use the command SHOW ERRORS. The message code of a PL/SQL warning has the form PLW-nnnnn. For the message codes of all PL/SQL warnings, see Oracle Database Error Messages. Table 11-1 summarizes the categories of warnings.

The application is connected to in oracle Oracle database and handles oracle error messages. It works like this Try 'Do oracle operations Catch Ex as OracleException 'Handle exception End Try In the database side, I'm creating some customized error messages : raise_application_error (-20000, 'Custom Error description'); My problem is that : I don't want any conflict between the Error number of default Oracle errors and mine. So I tried to use an Error Number outside default oracle interval (From 0000 to 62001) but I'm exception handling in getting the error "Ora-21000 error number argument to raise_application_error. 63000 is out of range" Does anyone have a workaround ? oracle share|improve this question edited Dec 25 '13 at 4:42 asked Dec 25 '13 at 4:21 Thomas Carlton 8863924 add a comment| 2 Answers 2 active oldest votes up vote 3 down vote accepted The user-defined error code range that you can use is in the range -20000..-20999. So, any values you assign in that range will work. You can read more about exception in the Oracle Docs share|improve this answer answered Dec 25 '13 at 4:44 OldProgrammer 6,19931025 add a comment| up vote 4 down vote The only error codes that it is valid for your application to use are -20000 to -20999 (giving you a range of 1000 error codes). You can use any of those without conflicting with Oracle database error codes. Some of Oracle's internal packages, though, do use error codes in that range. share|improve this answer answered Dec 25 '13 at 4:44 Justin Cave 160k14204250 Interesting. Justin, I had no idea that Oracle's internal packages used error codes in the range -20000 to -20999. That seems....odd. Do you know of an example? Thanks! –Mark J. Bobak Dec 25 '13 at 7:03 @MarkJ.Bobak - One example is that dbms_scheduler.drop_job can throw an ORA-20001 error if the job name is invalid matthiashoys.wordpress.com/2013/04/10/

What is a named programmer-defined exception in Oracle? Sometimes, it is necessary for programmers to name and trap their own exceptions - ones that aren't defined already by PL/SQL. These are called Named Programmer-Defined Exceptions. Syntax We will take a look at the syntax for Named Programmer-Defined Exceptions in both procedures and functions. Syntax for Procedures The syntax for the Named Programmer-Defined Exception in a procedure is: CREATE [OR REPLACE] PROCEDURE procedure_name [ (parameter [,parameter]) ] IS [declaration_section] exception_name EXCEPTION; BEGIN executable_section RAISE exception_name; EXCEPTION WHEN exception_name THEN [statements] WHEN OTHERS THEN [statements] END [procedure_name]; Syntax for Functions The syntax for the Named Programmer-Defined Exception in a function is: CREATE [OR REPLACE] FUNCTION function_name [ (parameter [,parameter]) ] RETURN return_datatype IS | AS [declaration_section] exception_name EXCEPTION; BEGIN executable_section RAISE exception_name; EXCEPTION WHEN exception_name THEN [statements] WHEN OTHERS THEN [statements] END [function_name]; Example Here is an example of a procedure that uses a Named Programmer-Defined Exception: CREATE OR REPLACE PROCEDURE add_new_order (order_id_in IN NUMBER, sales_in IN NUMBER) IS no_sales EXCEPTION; BEGIN IF sales_in = 0 THEN RAISE no_sales; ELSE INSERT INTO orders (order_id, total_sales ) VALUES ( order_id_in, sales_in ); END IF; EXCEPTION WHEN no_sales THEN raise_application_error (-20001,'You must have sales in order to submit the order.'); WHEN OTHERS THEN raise_application_error (-20002,'An error has occurred inserting an order.'); END; In this example, we have declared a Named Programmer-Defined Exception called no_sales in our declaration statement with the following code: no_sales EXCEPTION; We've then raised the exception in the executable section
