HDBC-ODBC under Windows
Categories: Libraries | How to
A brief description of how to get HDBC-ODBC working under windows, for connecting to things like MS SQL server.
[edit]
1 Install
- Ensure your path contains the ghc bin directory:
- Right click on My Computer, select Properties -> Advanced -> Environment variables -> change the variable 'Path'
- Download and install MDAC/ODBC Software Development Kit, from a link on this page:
http://msdn.microsoft.com/data/ref/mdac/downloads/ - Download and unpack the most recent versions of hdbc and hdbc-odbc from the HDBC homepage:
http://gopher.quux.org:70/devel/hdbc - Follow the README instructions for installing hdbc
- Follow the README instructions for installing hdbc-odbc, with these changes:
- The include-dirs line should be changed to:
include-dirs: . "C:\\Program Files\\Microsoft Data Access SDK 2.8\\Libs\\x86" - Do the following at a command prompt, with the hdbc-odbc directory being current directory:
- The include-dirs line should be changed to:
ghc --make -o setup Setup.hs
setup configure
setup build
setup install
You may need other ODBC drivers, but often they will be installed already on a development box that has the database server installed.

2 Test
You can test it from a ghci prompt (obviously you'll need to change the connection string and query):
Prelude> :m Database.HDBC
Prelude Database.HDBC> :m + Database.HDBC.ODBC
Prelude Database.HDBC Database.HDBC.ODBC> let connectionString = "Driver={SQL Server};Server=myserver;Database=mydatabase;Trusted_Connection=yes;"
Prelude Database.HDBC Database.HDBC.ODBC> let ioconn = connectODBC connectionString
Prelude Database.HDBC Database.HDBC.ODBC> do { conn <- ioconn; vals <- quickQuery conn "SELECT TOP 10 * FROM mytable;" []; print vals }
