[Haskell-beginners] Ranges and List Comprehensions in SQL

Hi Everyone, Is there a "From SQL"-type function that "restores" a range or list comprehension? Example: Let's say I want to keep track of which episodes of a TV show I've seen. I have an SQL table, in which is a record: id (INTEGER): 30 title (VARCHAR): "The Simpsons" episodes_watched (Some data format): [1..4], [14], [18..21], [23..25] Then, when I pull the record, in Haskell, the "Episodes Watched" is already one list: [1,2,3,4,14,18,19,21,23,24,25] , or a series of lists that I can append together: [1,2,3,4], [14], [18,19,20,21], [23,24,25] Note in the example that I would like to be able to store multiple ranges within a single record. Thanks so much for any help! Tom
