I was teaching SQL classes for YAPC-10 (“Yet Another PERL Conference” #10) at Carnegie Mellon University at the end of June 2009. For the record, I have never used PERL and had to Google up an overview before I went; it is a very different creature from SQL.
One of my students asked if you could write an SQL statement to generate the prime numbers less than 1000 (or any other limit) that scales well. He was bothered by the lack of loops in SQL and a Prime Number sieve is a common PERL programming exercise. You can Google it and see an animation at Eratosthenes' sieve and some PERL code at Sieve of Eratosthenes with closures...
