Question: K count, p1, p2 ,...... Pk, not necessarily a prime number. Add an exponent to these numbers. The final product between 0 and 10 is n, and all its factors are m. Ask if there is a power where m is 2, if multiple outputs have the largest index, if NO output is available.Http://poj.org/problem? Id = 1777Here we need to use a special prime

I will present a challenge, who can use Sqlseerver to propose the best method of calculating primes, I used a new feature CTE and some TSQL implementations, but none of them are ideal, the former (CTE) has a limit, while the latter (TSQL) produces 1 million primes in 7 minutes Can you do a better job? Here are some of my Code passages (TSQL Implementation) SET NOCOUNT ON Declare @prime table (prime int not
