What happens after the completion of the exception handler block?
After an exception handler runs, the current block stops executing and the enclosing block resumes with the next statement. If there is no enclosing block, control returns to the host environment.
What happens if a stored subprogram exits with an unhandled exception?
Unhandled exceptions can also affect subprograms. If you exit a subprogram successfully, PL/SQL assigns values to OUT parameters. However, if you exit with an unhandled exception, PL/SQL does not assign values to OUT parameters (unless they are NOCOPY parameters).
Is PL SQL dying?
The answer is that PL/SQL is not growing, but not going away either. Because it is used in the Oracle database, and the Oracle database is a fixture of enterprise systems world-wide, it will outlive you. High-performance batch processing has to happen close to the data, so PL/SQL will continue to rule in this area.
What will happen if an exception occurs in the base class?
Exception Handling – catching base and derived classes as exceptions: If both base and derived classes are caught as exceptions then catch block of derived class must appear before the base class.
Why do we need a default handler while implementing exceptions?
If the runtime system searches all methods on the call stack and the appropriate handler could not have been found, then runtime system handover to the default exception handler, which is part of a runtime system. This handler prints in the following format the exception data and abnormally terminates the program.
What are the complications when an exception occurs in PL SQL?
Once an exception occurs, the natural flow of execution is halted, and then the execution points to the exception section of the PL/SQL code. While the system defined exceptions are thrown by default, the user-defined ones have to be thrown explicitly by the RAISE keyword.
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 are exceptions in PL SQL?
Exception Handling in PL/SQL. An exception is an error which disrupts the normal flow of program instructions. PL/SQL provides us the exception block which raises the exception thus helping the programmer to find out the fault and resolve it.
Is Plsql faster?
“If you can do it in SQL, use SQL. But, curious as I am, I decided to run the same update in a block of PL/SQL code. Using BULK COLLECT and FORALL to minimize the context switches and LIMIT to manage my memory usage. And in my environment this PL/SQL code ran more than twice as fast as the SQL solution.
