ODBC claims to only support precisions up to 15, so maybe it's overreacting to the unsupported precision by truncating the number to an integer.

Can you try casting the field to a lower-precision numeric and let me know what happens? For example,

  select cast(creditawarded as numeric(10,4)) from ....

Another possible workaround for now would be to cast the field to a varchar and call string->number on the result.

I'll see if I can figure out what's going on, but I don't have a SQL Server test environment handy.

Hello everyone,

I attempting to use the Racket db interface to access a Microsoft SQL
Server 2005 database. The field "creditaward" is defined as
numeric(19,7), and in the case of the following query, I should get a
value of 1.25 rather than 1. Anyone have an idea how I get to the
fractional part?

The code:
#lang racket
(require db)
(define dbc (odbc-connect ...))
(query dbc "select creditawarded from ea7studentgrades where 
ea7studentcoursesid=58170")

The results:
(rows-result
  '(((name . "creditawarded")
     (typeid . 2)
     (size . 19)
     (digits . 7)))
  '(#(1)))

Here is the result of the same query using SQL Server Management Studio:
     creditawarded
     1.2500000
