Writing control structures


	Lesson 1 Writing control structures
		Now that you know how to build your first PL/SQL block, let us learn how to write control structures. Control structures allow you to program your logic based on a certain condition or while a particular condition is satisfied. In this module, you will learn about conditional control statements such as `IF-THEN`, as well as iterative control statements such as `LOOP` and `WHILE-LOOP`. Module objectives By the end of this module, you will know how to: Build logic by using the `IF-THEN-ELSE` and `ELSIF` statements Determine how to begin and end a simple loop in a PL/SQL block Observe the structure of `FOR` and `WHILE` loops Define uses for labels and `GOTO` statements In the next lesson, we will begin by building logic using `IF-THEN-ELSE` statements.
