In this lesson, you'll begin to master more methods for changing the order of execution of PL/SQL blocks. You'll explore statement labels, the GOTO statement, and the different kinds of loops. You'll learn how to branch by using the GOTO statement followed by a statement label. After that, the lesson will discuss why the statement label must appear in the same block and within the same scope as the GOTO statement. Next, you'll look at control structures. You'll learn about the different kinds of loops and how they operate. Finally, you'll discover techniques for exiting loops and how to simulate a REPEAT...UNTIL loop.
