SQL While Loop Alternatives Explained

In SQL, there is no while loop, instead iteration and recursion are used to achieve loop logic. Therefore, if you want to use functionality similar to a while loop, you can implement it through the following methods:

1. Using recursion: simulate the functionality of a while loop by calling the function within itself to implement the looping logic.
2. Using cursors: Using cursors in stored procedures or functions to iterate through a dataset can achieve functionality similar to a while loop.
3. Utilize loop structures: Use loop structures (such as FOR loops) in stored procedures or functions to iterate through a dataset, also achieving similar functionality to while loops.

In conclusion, although SQL does not have a syntax structure like a while loop, similar functionality can be achieved through methods such as recursion, cursors, or loop structures.
