Pl Sql Error Description
PROGRAM_ERROR PL/SQL has an internal problem. Raising Exceptions Explicitly To raise an exception explicitly, use either the RAISE statement or RAISE_APPLICATION_ERROR procedure. You might want to use a FOR or WHILE loop to limit the number of tries. For example, the following declaration raises an exception because the constant credit_limit cannot store numbers larger than 999: DECLARE credit_limit CONSTANT NUMBER(3) := 5000; -- raises an exception BEGIN ...
I want to... Also, it can use the pragma EXCEPTION_INIT to map specific error numbers returned by raise_application_error to exceptions of its own, as the following Pro*C example shows: EXEC SQL EXECUTE /* Execute You can avoid problems by declaring scalar variables with %TYPE qualifiers and record variables to hold query results with %ROWTYPE qualifiers. Redeclaring predefined exceptions is error prone because your local declaration overrides the global declaration. read the full info here
Functions For Error Trapping Are Contained In Which Section Of A Pl/sql Block
Give a raise to all remaining employees by multiplying their current salary by 200. In the following example, you declare an exception named past_due: DECLARE past_due EXCEPTION; Exception and variable declarations are similar. If the optional third parameter is TRUE, the error is placed on the stack of previous errors. So I can now save the new row in my error log, and a later rollback of the business transaction will not wipe out this information.
Topics RAISE Statement RAISE_APPLICATION_ERROR Procedure RAISE Statement The RAISE statement explicitly raises an exception. In Example 10-6, you alert your PL/SQL block to a user-defined exception named out_of_stock. If you recompile the subprogram with a CREATE OR REPLACE statement, the current settings for that session are used. Oracle Sqlcode List However, if you exit with an unhandled exception, PL/SQL does not assign values to OUT parameters (unless they are NOCOPY parameters).
Brittle code. Pl Sql Sqlcode Where is the kernel documentation? dbms_output.put_line(TO_CHAR(v_TimeStamp, 'DD-MON-YY HH24:MI:SS')); dbms_output.put(' Module: ' || p_Module); dbms_output.put(' Error #' || p_SeqNum || ': '); dbms_output.put_line(v_ErrorMsg); -- Output the call stack. https://docs.oracle.com/cd/E11882_01/timesten.112/e21639/exceptions.htm Example 4-2 Using RAISE statement to trap user-defined exception In this example, the department number 500 does not exist, so no rows are updated in the departments table.
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 Oracle Raise Exception With Message You need not declare them yourself. That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. PL/SQL predefines some common Oracle errors as exceptions.
Pl Sql Sqlcode
To have the enclosing block handle the raised exception, you must remove its declaration from the sub-block or define an OTHERS handler. https://docs.oracle.com/cd/E11882_01/appdev.112/e25519/errors.htm Trapping user-defined exceptions You can define your own exceptions in PL/SQL in TimesTen, and you can raise user-defined exceptions explicitly with either the PL/SQL RAISE statement or the RAISE_APPLICATION_ERROR procedure. Functions For Error Trapping Are Contained In Which Section Of A Pl/sql Block Place the sub-block inside a loop that repeats the transaction. Oracle Sql Error Codes User-defined exceptions must be raised explicitly by RAISE statements, which can also raise predefined exceptions.
Make your programs robust enough to work even if the database is not in the state you expect. If an exception is raised in the declaration section of a block, the exception will propagate to the outer block. Redeclaring predefined exceptions is error prone because your local declaration overrides the global declaration. INVALID_CURSOR 01001 -1001 A program attempts a cursor operation that is not allowed, such as closing an unopened cursor. Oracle Sql Codes List
Some common internal exceptions have predefined names, such as ZERO_DIVIDE and STORAGE_ERROR. I strongly suggest, however, that you never write exception handlers like this. Everything got rolled back. You need only include an exception-handling part in each block where errors might occur.
Here are some examples of WHEN clauses: Catch the NO_DATA_FOUND exception, usually raised when a SELECT-INTO statement is executed and finds no rows. Pl Sql Exception Handling Examples For internal exceptions, SQLCODE returns the number of the associated Oracle error. Errors could also occur at other times, for example if a hardware failure with disk storage or memory causes a problem that has nothing to do with your code; but your
The message code of a PL/SQL warning has the form PLW-nnnnn.
COMPILE statement. If no exception has been raised, SQLCODE returns zero and SQLERRM returns the message: ORA-0000: normal, successful completion. Note: Unreachable code could represent a mistake or be intentionally hidden by a debug flag. Sqlerror You can write handlers for predefined exceptions using the names in the following list: Exception Oracle Error SQLCODE Value ACCESS_INTO_NULL ORA-06530 -6530 CASE_NOT_FOUND ORA-06592 -6592 COLLECTION_IS_NULL ORA-06531 -6531 CURSOR_ALREADY_OPEN ORA-06511 -6511
Learn the names and causes of the predefined exceptions. This procedure accepts an integer (your error code), whose value must be between -20,999 and -20,000, and a string (your error message). LOOP -- could be FOR i IN 1..10 LOOP to allow ten tries BEGIN -- sub-block begins SAVEPOINT start_transaction; -- mark a savepoint /* Remove rows from a table of survey You might turn on all warnings during development, turn off all warnings when deploying for production, or turn on some warnings when working on a particular subprogram where you are concerned
With this technique, you should use a FOR or WHILE loop to limit the number of attempts. Exceptions can be internally defined (by the runtime system) or user defined. When this procedure is run, execution of the current PL/SQL block halts immediately and an exception (whose error code and message are set from the values passed to RAISE_APPLICATION_ERROR) is raised. A cursor FOR loop automatically opens the cursor to which it refers, so your program cannot open that cursor inside the loop.
Figure 10-1, Figure 10-2, and Figure 10-3 illustrate the basic propagation rules. Sometimes the error is not immediately obvious, and could not be detected until later when you perform calculations using bad data. Figure 10-1 Propagation Rules: Example 1 Description of the illustration lnpls009.gif Figure 10-2 Propagation Rules: Example 2 Description of the illustration lnpls010.gif Figure 10-3 Propagation Rules: Example 3 Description of the THEN RAISE past_due; END IF; END; ------------- sub-block ends EXCEPTION ...
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. Code that can never run By setting the compilation parameter PLSQL_WARNINGS, you can: Enable and disable all warnings, one or more categories of warnings, or specific warnings Treat specific warnings as INVALID_CURSOR Your program attempts an illegal cursor operation such as closing an unopened cursor. Specify a character string up to 2,048 bytes for your message.
