I want to connect from a COBOL/VMS system to an SQL Server 2005 instance. Could someone point me to a driver that works well?
This is similar to another question on SO. Though not specific to VMS, many of the options presented there would work with VMS/ODBC.
You may also want to look at FreeTDS (I've used it many times but never from VMS) if you are looking for an open source implementation you can customize. Otherwise, the supported/commercial vendors that have products that would work include Attunity, DataDirect, EasySoft, and CONNX.
