Loops are iterative control structures in PL/SQL.
They help you execute a set of commands repeatedly until the desired condition is met.
The types of loops are -
1. Simple or Infinite loops
2. For Loops used for cursors or numeric counters
3. While Loops
Each has distinct properties that determine when they be activated, how many times they will be executed and the termination condition.
Any PL/SQL book will give you an exhaustive explanation on the types and use of different loops. Even if you search for 'types of loops in PL/SQL' on any search engine, you will find articles.
Good Luck!
