NO_DATA_FOUND ORA-01403 The SELECT statement returned no rows or referenced a deleted element in a nested table or referenced an initialized element in an Index-By table. Then I reran everything just as in case4, except that the stored procedure was the one with the error trap and unnamed block the one without an error trap. However, the same scope rules apply to variables and exceptions. Returns the sequence number under which the error is stored.

Thus HandleAll should have been called with p_Top = TRUE. */ PROCEDURE StoreStacks(p_Module IN errors.module%TYPE, p_SeqNum OUT errors.seq_number%TYPE, p_CommitFlag BOOLEAN DEFAULT FALSE); END ErrorPkg; / Error Handling Package Body CREATE OR Related Links: Exception Handling: RAISE Examples & Syntax Example using RAISE Example using RAISE Example using RAISE Home : Code Library : Sponsors : Privacy : Terms of Usenet source: Ken Quirici (c.d.o.server - 29-Oct-2004) Basic Exception Handling With Error Basic Block Structure Handling CREATE OR REPLACE PROCEDURE IS BEGIN NULL; EXCEPTION WHEN THEN SYS_INVALID_ROWID The conversion of a character string into a universal rowid fails because the character string does not represent a valid rowid.

The functions SQLCODE and SQLERRM are especially useful in the OTHERS exception handler because they tell you which internal exception was raised. CASE 5: Then I deleted everything from the table 1 except the a1 = 1 and did a commit. How to decrypt a broken S/MIME message sent by Outlook?

The keyword OTHERS cannot appear in the list of exception names; it must appear by itself. Make sure you pass negative error numbers to SQLERRM. Also, PL/SQL does not roll back database work done by the subprogram. more hot questions question feed lang-sql about us tour help blog chat data legal privacy policy work here advertising info mobile contact us feedback Technology Life / Arts Culture / Recreation

If no handler is found, PL/SQL returns an unhandled exception error to the host environment. SUBSCRIPT_OUTSIDE_LIMIT 06532 -6532 A program references a nested table or varray element using an index number (-1 for example) that is outside the legal range. You can enable and disable entire categories of warnings (ALL, SEVERE, INFORMATIONAL, PERFORMANCE), enable and disable specific message numbers, and make the database treat certain warnings as compilation errors so that Internal exceptions are raised implicitly (automatically) by the run-time system.

Otherwise we rollback to the top-level 'virtual' savepoint currently in existence, which is my offending unnamed block. When Invalid Cursor Exception Demo CREATE OR REPLACE PROCEDURE invcur_exception IS CURSOR x_cur is SELECT * FROM all_tables; x_rec x_cur%rowtype; BEGIN LOOP -- note the cursor was not opened However, the same scope rules apply to variables and exceptions. That is, the exception reproduces itself in successive enclosing blocks until a handler is found or there are no more blocks to search.

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. If there is no handler for a user-defined exception, the calling application gets the following error: ORA-06510: PL/SQL: unhandled user-defined exception Reraising a PL/SQL Exception Sometimes, you want to reraise an In procedural statements, VALUE_ERROR is raised if the conversion of a character string into a number fails. (In SQL statements, INVALID_NUMBER is raised.) ZERO_DIVIDE 01476 -1476 A program attempts to divide That way, an exception handler written for the predefined exception can process other errors, as the following example shows: DECLARE acct_type INTEGER := 7; BEGIN IF acct_type NOT IN (1, 2,

If the transaction succeeds, commit, then exit from the loop. For example, PL/SQL raises the predefined exception NO_DATA_FOUND if a SELECT INTO statement returns no rows. So, you need not declare them yourself. You need not declare them yourself.

Note that you do not need to qualify raise_application_error with DBMS_STANDARD */ raise_application_error(-20101, 'Expecting at least 1000 tables'); ELSE NULL; -- Do the rest of the processing (for the non-error case). You can avoid unhandled exceptions by coding an OTHERS handler at the topmost level of every PL/SQL program. In order to do so, I need to reproduce a scenario where an SQL SELECT query will throw an error, but only while actually fetching from the cursor, not while executing You cannot raise a PL/SQL exception across languages; that is, you cannot raise a PL/SQL exception and have it captured by a calling Pro*C program - C has no exception handler

If the statement fails, Oracle rolls back to the savepoint. To reraise an exception, use a RAISE statement without an exception name, which is allowed only in an exception handler: Example 10-9 Reraising a PL/SQL Exception DECLARE salary_too_high EXCEPTION; current_salary NUMBER For example, perhaps a table you query will have columns added or deleted, or their types changed. It was very useful for my project! –SnakeSheet Jul 31 '14 at 10:49 1 This is a good practice.

EvenSt-ring C ode - g ol!f How should I interpret "English is poor" review when I used a language check service before submission? Make your programs robust enough to work even if the database is not in the state you expect. SUBSCRIPT_OUTSIDE_LIMIT ORA-06532 Reference to a nested table or varray index outside the declared range (such as -1). Are RingCT signatures malleable?

That way, you can report errors to your application and avoid returning unhandled exceptions. I created a table with the follwing: KEYCOL INTEGER PRIMARY KEY OTHERCOL VARCHAR2(100) I then created a few hundred rows with unique values for the primary key and the value l 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. For example, if you declare an exception named invalid_number and then PL/SQL raises the predefined exception INVALID_NUMBER internally, a handler written for INVALID_NUMBER will not catch the internal exception.

If you redeclare a global exception in a sub-block, the local declaration prevails. If you recompile the subprogram with an ALTER ... A cursor must be closed before it can be reopened. TIMEOUT_ON_RESOURCE A time-out occurs while Oracle is waiting for a resource.

That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. Use of the OTHERS handler guarantees that no exception will go unhandled. The functions SQLCODE and SQLERRM are especially useful in the OTHERS handler because they return the Oracle error code and message text. If your database operations might cause particular ORA- errors, associate names with these errors so you can write handlers for them. (You will learn how to do that later in this

Thus, a block or subprogram can have only one OTHERS handler. From there on, the exception propagates normally. Within this handler, you can call the functions SQLCODE and SQLERRM to return the Oracle error code and message text. Is it possible to change that message?
