Oracle Raise No_data_found
Keyword and Parameter Description exception_name A predefined or user-defined exception. For a list of raise user defined exception in oracle stored procedure the predefined exceptions, see "Summary of Predefined PL/SQL Exceptions". Usage Notes PL/SQL blocks and subprograms should RAISE an exception only when an error oracle user defined exception code range makes it impractical to continue processing. You can code a RAISE statement for a given exception anywhere within the scope of that exception. When an exception is raised, if PL/SQL cannot find a handler for it in the current block, the exception propagates to successive enclosing blocks, until

a handler is found or there are no more blocks to search. If no handler is found, PL/SQL returns an unhandled exception error to the host environment. In an exception handler, you can omit the exception name in a RAISE statement, which raises the current exception again. This technique allows you to take some initial corrective action (perhaps just logging the problem), then pass control to another handler that does more extensive correction. When an exception is reraised, the first block searched is the enclosing block, not the current block.

For example: 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.

What is a named programmer-defined exception in oracle stored procedure Oracle? Sometimes, it is necessary for programmers to name and trap their own exceptions - ones that aren't defined already by PL/SQL. These are called Named Programmer-Defined Exceptions. Syntax We will take a look at the syntax for Named Programmer-Defined Exceptions in both procedures and functions. Syntax for Procedures The syntax for the Named Programmer-Defined Exception in a procedure is: CREATE [OR REPLACE] PROCEDURE procedure_name [ (parameter [,parameter]) ] IS [declaration_section] exception_name EXCEPTION; BEGIN executable_section RAISE exception_name; EXCEPTION WHEN exception_name THEN [statements] WHEN OTHERS THEN [statements] END [procedure_name]; Syntax for Functions The syntax for the Named Programmer-Defined Exception in a function is: CREATE [OR REPLACE] FUNCTION function_name [ (parameter [,parameter]) ] RETURN return_datatype IS | AS [declaration_section] exception_name EXCEPTION; BEGIN executable_section RAISE exception_name; EXCEPTION WHEN exception_name THEN [statements] WHEN OTHERS THEN [statements] END [fun
