For example: We keep dialing a number until the call connects We read pages until a chapter ends We add items to a cart until shopping is complete Programming works in the same way. Instead of writing the same statement again and again, PL/SQL uses looping statements to repeat a block of code automatically . Looping statements help PL/SQL programs to: Reduce code length Improve readability Handle repetitive tasks efficiently Work with large data sets Without loops, PL/SQL programs would be long, slow, and difficult to maintain . What Is a Loop in PL/SQL? A loop is a control structure that allows a set of statements to be executed repeatedly based on a condition or a fixed number of times. In simple words: A loop tells PL/SQL: “Repeat this task until a certain rule is satisfied.” Every loop has three important parts: Initialization...
