Pl Sql Error Code 100


For example, an exception-handling part could have this syntax: EXCEPTION WHEN ex_name_1 THEN statements_1 -- Exception handler WHEN ex_name_2 OR ex_name_3 THEN statements_2 -- Exception handler WHEN OTHERS THEN statements_3 -- In PL/SQL, the pragma EXCEPTION_INIT tells the compiler to associate an exception name with an Oracle Database error number. The following block redeclares the predefined exception INVALID_NUMBER. The other internal exceptions can be given names. this content

To retrieve the message associated with the exception, the exception handler in the anonymous block invokes the SQLERRM function, described in "Error Code and Error Message Retrieval". To resolve these bugs, it is important to know where, when and why it happened. Does the code terminate? 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. https://docs.oracle.com/cd/B28359_01/appdev.111/b28370/errors.htm

Pl Sql Exception Handling Examples

How can I handle it? Try #2 succeeded. For example, PL/SQL raises the predefined exception NO_DATA_FOUND if a SELECT INTO statement returns no rows. Unlike variables, exceptions cannot appear in assignment statements or SQL statements.

Thus, the RAISE statement and the WHEN clause refer to different exceptions. When the exception is raised, the control jumps from the select statement to the exception handler routine. For the message codes of all PL/SQL warnings, see Oracle Database Error Messages. Pl Sql Exception When Others Carefully consider whether each exception handler should commit the transaction, roll it back, or let it continue.

You must raise user-defined exceptions explicitly. Find the super palindromes! In the sub-block, before the transaction starts, mark a savepoint. https://docs.oracle.com/cd/A97630_01/appdev.920/a96624/07_errs.htm Hot Network Questions What kind of weapons could squirrels use?

That is, the exception reproduces itself in successive enclosing blocks until a handler is found or there are no more blocks to search. Functions For Error Trapping Are Contained In Which Section Of A Pl/sql Block For more information, see "User-Defined Exceptions". An exception raised inside a handler propagates immediately to the enclosing block, which is searched to find a handler for this new exception. Defining Your Own PL/SQL Exceptions PL/SQL lets you define exceptions of your own.

The runtime system raises them implicitly (automatically). read the full info here MySQL? Pl Sql Exception Handling Examples Retrying a Transaction After an exception is raised, rather than abandon your transaction, you might want to retry it.

All Rights Reserved. http://iipseconline.com/pl-sql/pl-sql-error-handling-sql-code.html If you want execution to resume with the INSERT statement that follows the SELECT INTO statement, then put the SELECT INTO statement in an inner block with its own ZERO_DIVIDE exception You can, however, declare the same exception in two different blocks. http://download-west.oracle.com/docs/cd/B19306_01/appdev.102/b14261/exceptioninit_pragma.htm share|improve this answer edited Mar 7 '10 at 22:32 answered Mar 6 '10 at 8:55 Pavel Ulpi 493 see this link for correct syntax and working examle: docs.oracle.com/cd/B10500_01/appdev.920/a96624/07_errs.htm#8‌77 Pl Sql Exception Handling Continue Loop

Anyone considering using the services of an Oracle support expert should independently investigate their credentials and experience, and not rely on advertisements and self-proclaimed expertise. DUP_VAL_ON_INDEX 00001 -1 A program attempts to store duplicate values in a column that is constrained by a unique index. With exception handlers, you need not know every possible error or everywhere that it might occur. have a peek at these guys Retrying a Transaction After an exception is raised, rather than abandon your transaction, you might want to retry it.

For internal exceptions, SQLCODE returns the number of the Oracle error. Pl Sql Exception Handling Best Practices When the inner block raises past_due, the exception propagates to the outer block, where the name past_due does not exist. INVALID_NUMBER In a SQL statement, the conversion of a character string into a number fails because the string does not represent a valid number. (In procedural statements, VALUE_ERROR is raised.) This

You can use the pragma EXCEPTION_INIT to associate exception names with other Oracle Database error codes that you can anticipate.

Example 11-8 Redeclared Predefined Identifier DROP TABLE t; CREATE TABLE t (c NUMBER); In the following block, the INSERT statement implicitly raises the predefined exception INVALID_NUMBER, which the exception handler handles. Therefore, the values of explicit cursor attributes are not available in the handler. That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. Pl/sql Raises An Exception In Which Two Of The Following Cases Handle named exceptions whenever possible, instead of using WHEN OTHERS in exception handlers.

Examples of bad input data are incorrect or null actual parameters and queries that return no rows or more rows than you expect. Internally Defined Exceptions Internally defined exceptions (ORA-n errors) are described in Oracle Database Error Messages. ORA-06512: at line 21 ORA-01403: no data found" As you can see in the code of proc3, I have added a third parameter to the “RAISE_APPLICATION_ERROR”-procedure, telling it to keep the check my blog These system-errors always have an error number assigned, so you can easily identify the error.

Any help much appreciated. If no handler is found, PL/SQL returns an unhandled exception error to the host environment. Examples of internally defined exceptions are ORA-22056 (value string is divided by zero) and ORA-27102 (out of memory). Therefore, a PL/SQL block cannot handle an exception raised by a remote subprogram.

Example 11-14 Using a Locator Variable to Identify the Location of an Exception CREATE OR REPLACE PROCEDURE loc_var AS stmt_no NUMBER; name VARCHAR2(100); BEGIN stmt_no := 1; -- designates 1st SELECT Redeclaring predefined exceptions is error prone because your local declaration overrides the global declaration. The pragma must appear somewhere after the exception declaration in the same declarative section, as shown in Example 11-4. To invoke RAISE_APPLICATION_ERROR, use the following syntax: raise_application_error( error_number, message[, {TRUE | FALSE}]); where error_number is a negative integer in the range -20000..-20999 and message is a character string

The above code has been modified to handle an exception NO_DATA_FOUND. Example 11-5 gives the name deadlock_detected to the internally defined exception ORA-00060 (deadlock detected while waiting for resource) and uses the name in an exception handler. SQL> SQL> DECLARE 2 name EMPLOYEES.LAST_NAME%TYPE; 3 v_code NUMBER; 4 v_errm VARCHAR2(64); 5 BEGIN 6 SELECT last_name INTO name 7 FROM EMPLOYEES 8 WHERE EMPLOYEE_ID = -1; 9 EXCEPTION 10 WHEN In PL/SQL, the pragma EXCEPTION_INIT tells the compiler to associate an exception name with an Oracle error number.

Consider the following example: BEGIN ...
