Use sp_addmessage to add user-defined error messages and sp_dropmessage to delete user-defined error messages.RAISERROR can be used as an alternative to PRINT to return messages to calling applications. The error number and message can be trapped like any Oracle error. INVALID_CURSOR 01001 -1001 A program attempts a cursor operation that is not allowed, such as closing an unopened cursor. These conditions are not serious enough to produce an error and keep you from compiling a subprogram.

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 The following link provides lots of good information on this topic and Oracle exceptions in general. If you need to know which statement failed, you can use a locator variable: Example 10-14 Using a Locator Variable to Identify the Location of an Exception CREATE OR REPLACE PROCEDURE Raise_application_error Parameters Although you cannot anticipate all possible errors, you can plan to handle certain kinds of errors meaningful to your PL/SQL program.

When using msg_id to raise a user-defined message created using sp_addmessage, the severity specified on RAISERROR overrides the severity specified in sp_addmessage.Severity levels from 0 through 18 can be specified by Raise_application_error(-20001 VALUE_ERROR 06502 -6502 An arithmetic, conversion, truncation, or size-constraint error occurs.

Place the sub-block inside a loop that repeats the transaction. If the INSERT succeeds, we exit from the loop immediately.


In that case, we change the value that needs to be unique and continue with the next loop iteration. SYS_INVALID_ROWID 01410 -1410 The conversion of a character string into a universal rowid fails because the character string does not represent a valid rowid. Raise_application_error Vs Raise 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 Oracle Raise For a workaround, see "Defining Your Own Error Messages: Procedure RAISE_APPLICATION_ERROR".

The other internal exceptions can be given names. get redirected here The PRINT statement is not affected by TRY blocks, while a RAISERROR run with a severity of 11 to 19 in a TRY block transfers control to the associated CATCH block. 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.

An error message causes the compilation to fail.

SQL> insert into company values(1,1003,'C Inc.','Long Name C Inc.'); 1 row created.

RAISERROR supports character substitution similar to the functionality of the printf function in the C standard library, while the Transact-SQL PRINT statement does not. Before UPDATE ON employees 3.

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. The raise_application_error will also populate the SQL errors codes so that they can be programmatically handled. ================================================== The built in procedure RAISE_APPLICATION_ERROR in the DBMS_STANDARD package can be used for displaying That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram.

Execution of the handler is complete, so the sub-block terminates, and execution continues with the INSERT statement. With some better error checking, we could have avoided the exception entirely, by substituting a null for the answer if the denominator was zero, as shown in the following example. If the exception is ever raised in that block (or any sub-block), you can be sure it will be handled.
