F# and ADO.NET - idiomatic F#

Question

I\'m just starting to learn F#. I wrote this F#/ADO.NET code last night. In what ways would you improve the syntax - make it feel like idiomatic F#?

    let cn =         


        

Answer 1

I wrote a functional wrapper over ADO.NET for F#. With this library your example looks like this:

let openConn() =
   let cn = new OleDbConnection(cnstr)
   cn.Open()
   cn :> IDbConnection

let query sql = Sql.execReader (Sql.withNewConnection openConn) sql

let people = query "select * from people" |> List.ofDataReader
printfn "%d" people.Length
people |> Seq.iter (fun r -> printfn "%s" (r?LastName).Value)
