Range Of Error Codes In Oracle
Contents |
Churchill Run-time errors arise from design faults, coding mistakes, hardware failures, and many other sources. Although you cannot anticipate all possible errors, you can plan to handle certain kinds of errors oracle custom error codes range meaningful to your PL/SQL program. With many programming languages, unless you disable error oracle error codes table checking, a run-time error such 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

Exceptions can be internally defined (by the run-time system) or user defined. Examples of internally defined oracle exception 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 stops executing and the enclosing block resumes with the next statement. If there is no enclosing block, control returns to the host environment. In the example below, you calculate and store a price-to-earnings ratio for a company with ticker symbol XYZ. If the company has zero earnings, the predefined exception ZERO_DIVIDE is raised. This stops normal execution of the block and trans

The application is connected to 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 http://stackoverflow.com/questions/20769020/oracle-raise-custom-error-messages-without-conflict-with-default-error-ids 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 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 6,19831025 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 Interesti
you should consider them as your closest friends. They are the ones that honestly say what is wrong with your program. We cannot foresee all possible http://allthingsoracle.com/error-handling/ problematic events, and even the best programmers write bugs. Exceptions There are three kinds of exceptions Internally defined: A system error, defined by Oracle, that occurs. Predefined: The most common internally defined exceptions that are given predefined names. User defined: A logical error which you define and raise yourself System errors could occur from improper coding, like the “ORA-01001: Invalid cursor”, which you should error codes try to fix as soon as possible in your code. And the “TOO_MANY_ROWS”-error might give you clues about bad data quality. To resolve these bugs, it is important to know where, when and why it happened. But system errors could also occur from hardware failures, like the “ORA-12541: TNS: no listener”, when an ftp-server might be unreachable over the network. In that case, all you range of error can do, and should do, is provide proper error handling and transaction management, and give as detailed information as possible about this situation to the people that need to know. These system-errors always have an error number assigned, so you can easily identify the error. The 22 predefined exceptions also have a name assigned, which allows for easier, and more readable exception handling. For the other, non-predefined, system-errors, a name can be linked by using the pragma “EXCEPTION_INIT”. DECLARE network_error EXCEPTION; PRAGMA EXCEPTION_INIT(network_error, -12541); BEGIN ... EXCEPTION WHEN too_many_rows THEN ... WHEN network_error THEN ... END; User defined errors we will raise ourselves. They can be given a number and a name. To raise a user defined error with a chosen number and error message, we call the procedure “RAISE_APPLICATION_ERROR”. Oracle allows us the create error numbers in the range of -20000 to -20999. This allows us to create 1000 unique error codes for our logical errors throughout our application. Just like we did for system errors, we can name our user defined errors by using the pragma “EXCEPTION_INIT”. BEGIN RAISE_APPLICATION_ERROR(-20000,’Logical error occured’); END; If we do not care about the error c
