Oracle User Defined Error Messages
Contents |
Churchill Run-time errors arise from design faults, coding mistakes, hardware failures, and many oracle raise exception with message other sources. Although you cannot anticipate all possible errors, you oracle predefined exceptions can plan to handle certain kinds of errors meaningful to your PL/SQL program. With many programming

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.

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 exceptio

An exception can be either internally defined (by the run-time system) or user-defined. Examples of internally defined exceptions are ORA-22056 (value https://docs.oracle.com/cd/A97630_01/appdev.920/a96624/07_errs.htm string is divided by zero) and ORA-27102 (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 your own exceptions 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. User-defined exceptions must be given https://docs.oracle.com/cd/B28359_01/appdev.111/b28370/errors.htm 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 or invocations of the procedure DBMS_STANDARD.RAISE_APPLICATION_ERROR. 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. For information about managing errors when using BULK COLLECT, see Handling FORALL Exceptions (%BULK_EXCEPTIONS Attribute). Example 11-1 calculates a price-to-earnings ratio for a company. If the company has zero earnings, the division operation raises the predefined exception ZERO_DIVIDE, the execution of the block is interrupted, and control is transferred to the exception handlers. The optional OTHERS handler catches all exceptions that the block does not name specifically. Example 11-1 Run-Time Error Handling DECLARE stock_price NUMBER := 9.73; net_earnings NUMBER := 0; pe_ratio NUMBER; BEGIN -- Calculation might cause division-by-zero error. pe_ratio := stock_price / net_earnings; DBMS_OUTPUT.PUT_LINE('Price/earnings ratio = ' || pe_ratio

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 between the Error functions for 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 6,19931025 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 tha

PL/SQL supports programmers to catch such conditions using EXCEPTION block in the program and an appropriate action is taken against the error condition.
