How do you raise application error?

The RAISE_APPLICATION_ERROR procedure raises an exception based on a user-provided error code and message. This procedure is only supported in PL/SQL contexts.

Can an exception have raise statement?

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.

What happens if a stored subprogram exits with an unhandled exception?

Unhandled exceptions can also affect subprograms. However, if you exit with an unhandled exception, PL/SQL does not assign values to OUT parameters (unless they are NOCOPY parameters). Also, if a stored subprogram fails with an unhandled exception, PL/SQL does not roll back database work done by the subprogram.

What method do you use to assign a name to an error code exception?

The key thing for developers is to avoid hard-coding these error numbers in your code. Instead, use the EXCEPTION_INIT pragma to assign a name for that error code, and then handle it by name.

What happens when an exception is raised?

When an exception is raised, no further statements in the current block of code are executed.

How would you handle exceptions and still continue to process a PL SQL procedure?

By putting a BEGIN-END block with an exception handler inside of a loop, you can continue executing the loop if some loop iterations raise exceptions. You can still handle an exception for a statement, then continue with the next statement. Place the statement in its own subblock with its own exception handlers.

What happens if an exception is raised in the program and that exception is not handled by an exception section in either the current or enclosing PL SQL blocks?

If an exception is raised in your program and that exception is not handled by an exception section in either the current or enclosing PL/SQL blocks, that exception is “unhandled.” PL/SQL returns the error which raised an unhandled exception all the way back to the application environment from which PL/SQL was run.

What does an unhandled exception do?

An exception is a known type of error. An unhandled exception occurs when the application code does not properly handle exceptions. This code will throw exceptions if no file path is passed in or the file does not exist.
