This SQL query defines a recursive CTE named FibonacciCTE. It starts with two initial values: fib_n and fib_n_plus_1 set to 0 and 1 respectively, corresponding to the first two Fibonacci numbers. Then, it recursively generates the subsequent Fibonacci numbers by adding the current and previous Fibonacci numbers until reaching the desired limit (in this example, 10 Fibonacci numbers). Finally, the query selects the Fibonacci numbers from the CTE.
You can adjust the WHERE clause condition (n < 10 in this example) to control how many Fibonacci numbers you want to generate.
