You can also learn how to create recursive queries or common table expressions (CTEs) in our Recursive Queries course. Now you know that SQL is Turing complete and thus, computationally universal.

What is looping statement in SQL?

The LOOP statement is a special type of looping statement, because it has no terminating condition clause. It defines a series of statements that are executed repeatedly until another piece of logic, generally a transfer of control statement, forces the flow of control to jump to some point outside of the loop.
