Hi
I’ve created an ADO.NET implementation for DBI but I may have overlooked
some stuff.
At the moment it’s living on google code
http://code.google.com/p/ironruby-dbi
There is an extra colon in the connection string required to make it
select
the correct data provider.
DBI.connect(“DBI:ADONET*:MSSQL*:Data Source=(local);initial
catalog=mydb;user id=sa;password=topsecret”)
Feel free to test and tell me what’s wrong with it 
I’ve only tested it against SQL Server…
This should make implementing the activerecord adapters for rails a
little
bit easier because in many cases it’s just a matter of changing the
connection string of an existing adapter (at least that’s what I’m
hoping
for).
Cheers
Ivan
