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 :

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;

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,
