Seems to connect fine to SQLServer. Simple to understand and debug. Would recommend for those who are new to using C++ drivers for SQL Server on Linux. One issue I find with this is it restricts size for columns and not sure why this is necessary when you have the ability to allocate space dynamically and safety checks could be left up to the developer of the code using this.
Tested with a MS Access db. Works fine :) Nice and simple interface. Easy to compile.
