[Haskell-cafe] HDBC-ODBC, bindCol

Hi John,

I've just been going  through the HDBC-ODBC code wondering if I could 
find the spot that needs changing so that Doubles work properly with 

Could you please tell me, if I understand this correctly?

The bindCol function does not actually look at the particular value 
type, ie. SqlDouble, SqlInteger ..., to determine the type but queries 
the database via sqlDescribeParam to get the type.

Which might fail though and not leave a clue. In that case the SqlType 
still isn't used, but rather some default?

If I was more literate in Haskell I would propably be able to answer 
this myself, sry, I'll catch up.

And I had a hell of a time finding an SQL/ODBC for C Tutorial and never 
coded in C.

Thanks upfront
