If you're looking for a guide to using Haskell in the real world, you should check out "Real World Haskell", by O'Sullivan et al, freely available online at [1]. It's an excellent book, in my opinion one of the best programming books available on any language. In particular, for interacting with MySQL, check out the chapter on that in RWH [2], and for reading lines and operating on them, see [3]. However, you should start from the beginning, as those kind of operations (for better or worse), require a firm grounding in Haskell concepts like types, monads, etc. [1]: http://book.realworldhaskell.org/read/ http://book.realworldhaskell.org/read/ [2]: http://book.realworldhaskell.org/read/using-databases.html http://book.realworldhaskell.org/read/using-databases.html [3]: http://book.realworldhaskell.org/read/io.html http://book.realworldhaskell.org/read/io.html
