SQL pretzels created while experimenting with hallucinogens?

In an interview for the NoCOUG Journal (, Steven Feuerstein was asked: “SQL is a set-oriented non-procedural language; i.e., it works on sets and does not specify access paths. PL/SQL on the other hand is a record-oriented procedural language, as is very clear from the name. What is the place of a record-oriented procedural language in the relational world?”

To prove Steven correct, NoCOUG has held four international SQL challenges.(read more)
