Hi *,
The title is self-explanatory. I'd like to store information from
an algebraic data type in an SQL database, but the type signature of
toSql (toSql
:: Data.Convertible.Base.Convertible a SqlValue => a -> SqlValue)
doesn't make sense to me.
How is this done (how do I make an instance of a typeclass like that?)Thanks for your time, Tom _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
