example of value error in pl sql Christchurch, Virginia

ORA-00001: unique constraint violated ORA-00054: resource busy and acquire with NOWAIT specified or timeout expired ORA-00257: archiver error ORA-00600: internal error ORA-00604: error occurred at recursive SQL level 1 ORA-00900: invalid A GOTO statement cannot branch into an exception handler, or from an exception handler into the current block. END; Omitting the exception name in a RAISE statement--allowed only in an exception handler--reraises the current 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. 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 Your program attempts to divide a number Description When you encounter an ORA-06502 error, the following error message will appear: ORA-06502: PL/SQL: numeric or value error Cause You tried to execute a statement that resulted in an arithmetic, END; You can still handle an exception for a statement, then continue with the next statement.

More info on ORA-6502: A user on Oracle DBA Forums encountered ORA-6502 as related to this SQL: connected to: Oracle 9i Enterprise Edition Release 9.2.5.0 - Production With Partitioning, OLAP and After an exception handler runs, the current block stops executing and the enclosing block resumes with the next statement. With PL/SQL, a mechanism called exception handling lets you "bulletproof" your program so that it can continue operating in the presence of errors. Carefully consider whether each exception handler should commit the transaction, roll it back, or let it continue.

Retrying a Transaction After an exception is raised, rather than abandon your transaction, you might want to retry it. Raising Exceptions with the RAISE Statement PL/SQL blocks and subprograms should raise an exception only when an error makes it undesirable or impossible to finish processing. Copyright © 2003-2016 TechOnTheNet.com. If you exit a subprogram successfully, PL/SQL assigns values to OUT parameters.

You can correct this error by assigning the variable called v_number a proper numeric value. The second way this error message will occur is if a value being assigned to a numeric variable exceeds the numerical size that the variable can function under. THEN -- handle the error WHEN OTHERS THEN -- handle all other errors END; If you want two or more exceptions to execute the same sequence of statements, list the exception If the parameter is FALSE (the default), the error replaces all previous errors.

Because this exception is used internally by some SQL functions to signal that they are finished, you should not rely on this exception being propagated if you raise it within a Retrieving the Error Code and Error Message: SQLCODE and SQLERRM In an exception handler, you can use the built-in functions SQLCODE and SQLERRM to find out which error occurred and to Consider the following example: DECLARE pe_ratio NUMBER(3,1); BEGIN DELETE FROM stats WHERE symbol = 'XYZ'; BEGIN ---------- sub-block begins SELECT price / NVL(earnings, 0) INTO pe_ratio FROM stocks WHERE symbol = You declare an exception by introducing its name, followed by the keyword EXCEPTION.

EXCEPTION WHEN NO_DATA_FOUND THEN -- catches all 'no data found' errors Instead of checking for an error at every point it might occur, just add an exception handler to your PL/SQL All Rights Reserved. Good Term For "Mild" Error (Software) Any better way to determine source of light by analyzing the electromagnectic spectrum of the light Players stopping other player actions At first I was Oracle technology is changing and we strive to update our BC Oracle support information.

You could correct this error by redefining the v_number variable as number(3). The keyword OTHERS cannot appear in the list of exception names; it must appear by itself. In the code we assign a big string to ‘msg'. If the transaction fails, control transfers to the exception handler, where you roll back to the savepoint undoing any changes, then try to fix the problem.

However, other user-defined exceptions must be raised explicitly by RAISE statements. RAISE_APPLICATION_ERROR is part of package DBMS_STANDARD, and as with package STANDARD, you do not need to qualify references to it. This error message is generally a quick fix, but there are some ways you can expedite the process (or avoid the error altogether).

For example, this error occurs if an attempt is made to assign the value NULL to a variable declared NOT NULL, or if an attempt is made to assign an integer An error message causes the compilation to fail. Figure7-1, Figure7-2, and Figure7-3 illustrate the basic propagation rules. However, if you exit with an unhandled exception, PL/SQL does not assign values to OUT parameters (unless they are NOCOPY parameters).

For example, this error message could result from attempting to execute a statement by assigning an integer a value greater than 99 when the variable is set to NUMBER(2). The technique is: Encase the transaction in a sub-block. pe_ratio := stock_price / net_earnings; dbms_output.put_line('Price/earnings ratio = ' || pe_ratio); EXCEPTION -- exception handlers begin -- Only one of the WHEN blocks is executed. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts.

Resolution Let's look at three options on how to resolve the ORA-06502 error: Option #1 - Value too large In our first option, this error occurs when you try to assign If no handler is found, PL/SQL returns an unhandled exception error to the host environment. You could correct this error by redefining the v_number variable as number(3). Unhandled exceptions can also affect subprograms.

If earnings are zero, the function DECODE returns a null. So, your program cannot open that cursor inside the loop. ALTER PROCEDURE dead_code COMPILE; See Also: ALTER PROCEDURE, DBMS_WARNING package in the PL/SQL Packages and Types Reference, PLW- messages in the Oracle Database Error Messages Previous Next Copyright©1996, 2003OracleCorporation All Rights If an error occurs in the sub-block, a local handler can catch the exception.

You might store such information in a separate table. BEGIN ---------- sub-block begins ... Exceptions declared in a block are considered local to that block and global to all its sub-blocks. When called, raise_application_error ends the subprogram and returns a user-defined error number and message to the application.

The maximum length of an Oracle error message is 512 characters including the error code, nested messages, and message inserts such as table and column names. VALUE_ERROR An arithmetic, conversion, truncation, or size-constraint error occurs. CREATE OR REPLACE PROCEDURE dead_code AS x number := 10; BEGIN if x = 10 then x := 20; else x := 100; -- dead code (never reached) end if; END However, an exception name can appear only once in the exception-handling part of a PL/SQL block or subprogram.

If there is no handler for a user-defined exception, the calling application gets this error: ORA-06510: PL/SQL: unhandled user-defined exception Reraising a PL/SQL Exception Sometimes, you want to reraise an exception, SELF_IS_NULL Your program attempts to call a MEMBER method on a null instance. A PL/SQL block cannot catch an exception raised by a remote subprogram. Taking these basic steps should aid in making your Oracle experience a stress-free and prosperous endeavor!

Note: When using pragma RESTRICT_REFERENCES to assert the purity of a stored function, you cannot specify the constraints WNPS and RNPS if the function calls SQLCODE or SQLERRM. If there is no enclosing block, control returns to the host environment. END; The enclosing block does not handle the raised exception because the declaration of past_due in the sub-block prevails. Although you cannot anticipate all possible errors, you can plan to handle certain kinds of errors meaningful to your PL/SQL program.
