If the third parameter of is , the error code is put on top of the error stack, if it is , the error stack is replaced with the error message.

The default for this parameter is .

Using Locator Variables to Identify Exception Locations

Using one exception handler for a sequence of statements, such as , , or statements, can mask the statement that caused an error. If you need to know which statement failed, you can use a :

Example Using a Locator Variable to Identify the Location of an Exception

CREATE OR REPLACE PROCEDURE loc_var AS stmt_no NUMBER; name VARCHAR2(); BEGIN stmt_no := 1; -- designates 1st SELECT statement SELECT table_name INTO name FROM user_tables WHERE table_name LIKE 'ABC%'; stmt_no := 2; -- designates 2nd SELECT statement SELECT table_name INTO name FROM user_tables WHERE table_name LIKE 'XYZ%'; EXCEPTION WHEN NO_DATA_FOUND THEN DBMS_sprers.eu_LINE('Table name not found in query ' max_salary raise_application_error syntax oracle SUBSTR (given_name_in, 1, 1); END IF; RETURN (formatted_name); EXCEPTION WHEN OTHERS THEN RAISE_APPLICATION_ERROR (, 'Invalid name supplied.'); END;

How does the output differ when the surname is not supplied, raise_application_error syntax oracle, as opposed to when the given name is not supplied?

How would you change the program in to take advantage of the locally defined exceptions?

Which of the following code segments trap the exception raised and provide the most information about the error that occurred? What is the difference between the two code blocks, and which provides greater control?

DECLARE bad_data EXCEPTION; BEGIN RAISE bad_data; EXCEPTION WHEN bad_data THEN DBMS_sprers.eu_LINE ('data was bad: '


The built in procedure RAISE_APPLICATION_ERROR in the DBMS_STANDARD package can be used for displaying the user defined error message and raise_application_error syntax oracle error number whose range must be between to The exception raised by this procedure cannot be handled explicitly with a name as it does not have one and must be handled only through the OTHERS handler, raise_application_error syntax oracle. Whenever this exception occurs, all the uncommitted transactions in the current session will be rolled back to its previous state.

%Note: The error code of the predefined exceptions cannot be used in this procedure.

The prototype for defining this exception is shown below,

RAISE_APPLICATION_ERROR(<Error_code>, <Error_message> [, True
