Fix Application Error Area
If you are getting an Application Error Scope Enlargement error message on your computer, then you should check out these recovery methods.
Don’t let Windows errors hold you back.
The built-in procedure RAISE_APPLICATION_ERROR in the DBMS_STANDARD package can be used later to display a user-specified error message and an error selector whose range -20000 to -20999 should be compared.
Output. This guide provides guidelines for using the
raise_application_error procedure, which generates custom error messages.
An Introduction To The Real
How do you raise application error?
The provider number associated with the error code before it was stored in a variable named SQLCODE. The RAISE_APPLICATION_ERROR procedure accepts a user-specified error count rate from -20000 to 2 . 20999 The SQLCODE returned in the error message is SQL0438N.
raise_application_error procedure allows you to raise a custom error from a large block of code or from a saved program.
This method allows you to signal problems to callers by returning unhandled exceptions instead.
How do you resolve ORA 20000?As mentioned earlier, the ORA-06512 error and the ORA-20000 error are often related. To fix these errors, the user must fix the condition causing the errors, or sometimes write an exception handler. To begin fixing the error stack, review the code in the relevant lines of the error message.
Code language: SQL (Structured Query Language) (sql)
raise_application_error( error number, news [, NOT PROPERLY]);
error_numberis a malicious integer in the range
messageis mother nature herself, this string represents the error message. It can be up to 2048 bytes long.
FALSE, the error replaces any previous misunderstanding. If
TRUE, our own error will be added to the previous errors.
raise_application_error is specific to the user package
DBMS_STANDARD, so you probably don’t need qualified references that can do this.
When executing a
raise_application_error procedure, Oracle may immediately stop the execution of the current completion. This will also undo any changes made to the
Note that traded changes to the global data structure are compressed variables, and database tools such as spreadsheets are not collapsed. Therefore, you must explicitly execute the
ROLLBACK statement to reverse the effect of the DML.
Let’s look at some products that use
raise_application_error to throw exceptions.
This example uses the defined procedure
raise_application_error to throw an exception from the identifierand
-20111 and the message
'Credit limit exceeded':
SQL code (Structured Query Language) (sql)
EXPLAIN credit_limit_exceed EXCEPTION; PRAGMA exception_init(credit_limit_exceed, -20111); l_customer_id customer.customer_id%TYP := &customer_id; L_customer credit limit.credit limit%TYPE := &credit limit; Customers l_customer_credit.credit_limit%TYPE; TO BEGIN SELECT credit_limit In l_customer_credit clients WHERE client_id is equal to client_id; IF l_credit_customer > l_credit_limit THEN raise_application_error(-20111, 'Credit limit exceeded'); END IF; Dbms_output .put_line('Check and exceed credit limit'); AN EXCEPTION IF NO_DATA_FOUND THEN dbms_output.put_line('Customer id wi || || l_customer_id ' probably doesn't exist. Language: ');End;/
credit_limit_exceedwith error number
l_credit_limitof the customer store ID and credit limit entered by users.
raise_application_errorthrow an exception.
In this tutorial, you learned how to use the Oracle procedure
raise_application_error to throw an exception.
Why do we use raise application error?
You can use the RAISE_APPLICATION_ERROR procedure to print custom ORA error messages from stored routines. This tactic allows you to report errors to the application and avoid throwing unhandled exceptions. ny.
RAISE_APPLICATION_ERROR only accepts numbers between -20999 and -20000 to get the
error_code parameter. However, between -20999 which becomes -20000, you can use any number of errors without limitation. Any “organization” of the numbers is up to you. If you specify a number outside of this range, another fatal exception will be thrown ~
ORA-21000: The raise_application_error error number argument associated with -xxxxx is out of range. For example:
START RAISE_APPLICATION_ERROR(-54321, 'This is a completely invalid error code');END;
ORA-21000: error selection argument for bug_promotion_application -54321 out of rangeORA-06512: on beam 2
Note that you cannot pass an SQLCODE to RAISE_APPLICATION_ERROR because the SQLCODE generated isGiven by Oracle always out of range for
RAISE_APPLICATION_ERROR to pass SQLCODE to
RAISE_APPLICATION_ERROR. The advantage of throwing a system exception is that such a DUP_VAL_ON_INDEX must use a specific version of the RAISE document with no arguments. For example, let’s rephrase your computer:
PROCEDURE insert_record(v_row IN OUT TABLE1%ROWTYPE) YES l_err_code NUMBER; l_err_message VARCHAR(200); TO BEGIN INSERT IN TABLE 1.... RETURN ID IN V_row.id; AN EXCEPTION IF DUP_VAL_ON_INDEX THEN :matches SQLCODE_err_code; l_err_message := 'Entry already exists!'; -- Write errors here -- Now create an exception for the different external manager that should manage this. -- Note that there is no system in this case to include the new error in the entire message. LIFT UP; IF OTHERS THEN l_err_code: stands for SQLCODE; l_err_message := 'Insert error: a - ' || SQLERRM; --- Error log here -- Now rethrow the exception so that the outer handler can handle it. who has LIFT;END insert_record;
