[Haskell-cafe] Fwd: hdbc parametrized select

This was not sent to the cafe since I used the wrong from address. ---------- Forwarded message ---------- From: Asten, W.G.G. van (Wilfried, Student M-CSC) Date: Thu, Oct 18, 2012 at 12:27 PM Subject: Re: [Haskell-cafe] hdbc parametrized select To: s9gf4ult@gmail.com Cc: haskell-cafe@haskell.org To my knowledge you can combine execute and the fetch functions like this: find conn id = do stmt <- prepare conn "SELECT * FROM table WHERE id = ? LIMIT 1" excute stmt [id] row <- fetchRow stmt On Thu, Oct 18, 2012 at 10:51 AM, wrote:

does hdbc have parametrized selects ? There is execute execute :: Statement -> [SqlValue] -> IO Integer and some other functions which get list of parameters but return IO Integer or IO () and there is other couple of functions fetchRow :: Statement -> IO (Maybe [SqlValue]) which return values of select but do not get parameters

How can i execute parametrized select with hdbc ?
