RAISE_APPLICATION_ERROR tips raise_application_error(-20001 Oracle Database Tips by Burleson Consulting March 3, 2015 Question: What does the PL/SQL raise_application_error code do? Answer: The raise_application_error is actually a procedure defined by raise_application_error parameters Oracle that allows the developer to raise an exception and associate an error number and message with the procedure. This allows the application to raise application errors rather than just Oracle errors. Error numbers are defined between -20,000 and -20,999. Oracle provides the raise_application_error procedure to allow you to raise custom errorRaise Application Error In Oracle Triggers
numbers within your applications. You can generate errors and their associated text starting with -20000 and proceeding through -20999 (a grand total of 1,000 error numbers that you can use). Below we illustrate the use of the raise_application_error procedure. Using the raise_application_error procedure: DECLARE Balance integer := 24; BEGIN IF (nBalance <= 100) THEN Raise_Application_Error (-20343, 'The balance is too low.');END IF;END; In this example, error number -20343 is raised if the value of nBalance isn't greater than 100, yielding a message that looks like this: ORA-20343: The balance is too low. All other numbers belong to Oracle for its own errors. The message can be anything that will fit in a varchar2(2000). The final parameter passed to the procedure is a Boolean(true/false) that tells the procedure to add this error to the error stack or replace all errors in the stack with this error. Passing the value of 'True' adds the error

For example: raise application error DECLARE ex_custom EXCEPTION; BEGIN RAISE ex_custom; EXCEPTION WHEN ex_custom THEN DBMS_OUTPUT.PUT_LINE(SQLERRM); END; / The output is "User-Defined Exception". Is it possible to change that message? EDIT: Here is some more detail. I hope this one illustrates what I'm trying to do better. DECLARE l_table_status VARCHAR2(8); l_index_status VARCHAR2(8); l_table_name VARCHAR2(30) := 'TEST'; l_index_name VARCHAR2(30) := 'IDX_TEST'; ex_no_metadata EXCEPTION; BEGIN BEGIN SELECT STATUS INTO l_table_status FROM USER_TABLES WHERE TABLE_NAME = l_table_name; EXCEPTION WHEN NO_DATA_FOUND THEN -- raise exception here with message saying -- "Table metadata does not exist." RAISE ex_no_metadata; END; BEGIN SELECT STATUS INTO l_index_status FROM USER_INDEXES WHERE INDEX_NAME = l_index_name; EXCEPTION WHEN NO_DATA_FOUND THEN -- raise exception here with message saying -- "Index metadata does not exist." RAISE ex_no_metadata; END; EXCEPTION WHEN ex_no_metadata THEN DBMS_OUTPUT.PUT_LINE('Exception will be handled by handle_no_metadata_exception(SQLERRM) procedure here.'); DBMS_OUTPUT.PUT_LINE(SQLERRM); END; / In reality, there are dozens of those sub-blocks. I'm wondering if there's a way to have a single user-defined exception for e

What is the WHEN OTHERS clause in Oracle? The WHEN OTHERS clause is used to trap all remaining exceptions that have not been handled by your Named System Exceptions and Named Programmer-Defined Exceptions. Syntax We will take a look at the syntax for the WHEN OTHERS clause in both procedures and functions. Syntax for Procedures The syntax for the WHEN OTHERS clause in a procedure is: CREATE [OR REPLACE] PROCEDURE procedure_name [ (parameter [,parameter]) ] IS [declaration_section] BEGIN executable_section EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [procedure_name]; Syntax for Functions The syntax for the WHEN OTHERS clause in a function is: CREATE [OR REPLACE] FUNCTION function_name [ (parameter [,parameter]) ] RETURN return_datatype IS | AS [declaration_section] BEGIN executable_section EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [function_name]; Example Here is an example of a procedure that uses a WHEN OTHERS clause: CREATE OR REPLACE PROCEDURE add_new_order (order_id_in IN NUMBER, sales_in IN NUMBER) IS no_sales EXCEPTION; BEGIN IF sales_in = 0 THEN RAISE no_sales; ELSE INSERT INTO orders (order_id, total_sales ) VALUES ( order_id_in, sales_in ); END IF; EXCEPTION WHEN DUP_VAL_ON_INDEX THEN raise_application_error (-20001,'You have tried to insert a duplicate order_id.'); WHEN no_sales THEN raise_application
