In this Video, I have explained RAISE_APPLICATION_ERROR user defined exception in oracle plsql with example.
What is RAISE_APPLICATION_ERROR
RAISE_APPLICATION_ERROR in Oracle PL/SQL is a procedure of package DBMS_STANDARD that lets you create your own custom error messages.
It's used when you want to report specific problems in your database programs, like stored procedures, functions, or triggers.
Instead of relying on the standard error messages from Oracle, you can define and raise errors that are more meaningful and relevant to your specific application.
Syntax of RAISE_APPLICATION_ERROR
RAISE_APPLICATION_ERROR(error_number, message);
error_number: A negative integer between -20000 and -20999. This is the error code you define for your custom error.
message: A string containing the error message (up to 2048 bytes).
