The RAISE statement is used to explicitly raise an exception and display an error message, returned by the SQLERRM built-in function, and an error code, returned by the SQLCODE built-in function. Also see "Unsupported predefined errors". Catching Unhandled Exceptions Remember, if it cannot find a handler for a raised exception, PL/SQL returns an unhandled exception error to the host environment, which determines the outcome. Oracle recommends using DBMS_UTILITY.FORMAT_ERROR_STACK, except when using the FORALL statement with its SAVE EXCEPTIONS clause, as in Example 12-13. http://vbview.net/oracle-error/oracle-error-help.php
Though they share the same name, the two past_due exceptions are different, just as the two acct_num variables share the same name but are different variables. Exception Propagation If an exception is raised in a block that has no exception handler for it, then the exception propagates. Write out debugging information in your exception handlers. To get more information, run ttIsql and use the command show errors. https://docs.oracle.com/cd/A97630_01/appdev.920/a96624/07_errs.htm
In the exception-handling part of the sub-block, put an exception handler that rolls back to the savepoint and then tries to correct the problem. What change can I make in the following procedure so that it will compile without error? You can use the RAISE statement to raise a user-defined exception or an Oracle Database predefined exception.
Therefore, the values of explicit cursor attributes are not available in the handler. 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 NULL; EXCEPTION SELF_IS_NULL ORA-30625 -30625 Program attempted to invoke a MEMBER method, but the object was not initialized. Exception Handling In Oracle 11g Example Using the DBMS_WARNING Package If you are writing a development environment that compiles PL/SQL subprograms, you can control PL/SQL warning messages by calling subprograms in the DBMS_WARNING package.

THEN -- handle the error WHEN ... Passing a zero to SQLERRM always returns the message normal, successful completion.
Execution of the handler is complete, so the sub-block terminates, and execution continues with the INSERT statement. Oracle 11g Error Codes That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. Exceptions can be internally defined (by the run-time system) or user defined. Continuing after an Exception Is Raised An exception handler lets you recover from an otherwise fatal error before exiting a block.
Running this in TimesTen results in the following. http://www.oracle.com/pls/db92/db92.error_search?prefill=ORA- If the transaction succeeds, the COMMIT and EXIT statements execute. Oracle Sqlerrm So, only an OTHERS handler can catch the exception. Oracle Error Handling Once the exception name is lost, only an OTHERS handler can catch the exception.
Example 11-18 Exception Raised in Exception Handler is Handled by Invoker CREATE PROCEDURE print_reciprocal (n NUMBER) AUTHID DEFINER IS BEGIN DBMS_OUTPUT.PUT_LINE(1/n); EXCEPTION WHEN ZERO_DIVIDE THEN DBMS_OUTPUT.PUT_LINE('Error:'); DBMS_OUTPUT.PUT_LINE(1/n || ' is undefined'); check over here Topics Raising User-Defined Exception with RAISE Statement Raising Internally Defined Exception with RAISE Statement Reraising Current Exception with RAISE Statement Raising User-Defined Exception with RAISE Statement In Example 11-9, the procedure RAISE_APPLICATION_ERROR is part of package DBMS_STANDARD, and as with package STANDARD, you do not need to qualify references to it. In the following example, the INSERT statement might raise an exception because of a duplicate value in a unique column. Oracle Error Codes List With Description
If the exception handler is in an anonymous block, then control transfers to the host environment (for example, SQL*Plus) If an exception is raised in a block that has no exception INVALID_NUMBER ORA-01722 -1722 Conversion of character string to number failed. INVALID_CURSOR ORA-01001 You tried to reference a cursor that does not yet exist. his comment is here If no handler is found, PL/SQL returns an unhandled exception error to the host environment.
The PL/SQL language does not include these constructs. Oracle Error Codes Table An internally defined exception always has an error code, but does not have a name unless PL/SQL gives it one or you give it one. In the latter case, PL/SQL returns an unhandled exception error to the host environment.
For example, when an open host cursor variable is passed to a stored subprogram, the return types of the actual and formal parameters must be compatible. 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. However, when an exception is raised inside a cursor FOR loop, the cursor is closed implicitly before the handler is invoked. Oracle Error Codes And Solution Pdf END; You can still handle an exception for a statement, then continue with the next statement.
Learn the names and causes of the predefined exceptions. Databases SQL Oracle / PLSQL SQL Server MySQL MariaDB PostgreSQL SQLite MS Office Excel Access Word Web Development HTML CSS Color Picker Languages C Language More ASCII Table Linux UNIX Java Figure 11-1 Exception Does Not Propagate Description of "Figure 11-1 Exception Does Not Propagate" In Figure 11-2, the inner block raises exception B. http://vbview.net/oracle-error/oracle-error-jvm-dll.php The inner block does not have an exception handler for exception B, so B propagates to the outer block, which does have an exception handler for it.
The number that SQLCODE returns is negative unless the Oracle error is no data found, in which case SQLCODE returns +100. If there is no enclosing block, control returns to the host environment. STORAGE_ERROR PL/SQL runs out of memory or memory has been corrupted. The following block includes a WHEN OTHERS handler, which should trap any exception raised in the block and simply display the error code: DECLARE l_number NUMBER (1) := 100; BEGIN statement1;
If a subprogram exits with an unhandled exception, then actual parameters for OUT and IN OUT formal parameters passed by value (the default) retain the values that they had before the For example, in Example 11-23, after the SELECT INTO statement raises ZERO_DIVIDE and the exception handler handles it, execution cannot continue from the INSERT statement that follows the SELECT INTO statement. You can use the pragma EXCEPTION_INIT to associate exception names with other Oracle error codes that you can anticipate.
