I'm not an Erlang dev, but a quick look at the Erlang docs shows:
"If you need to access a relational database such as sqlserver, mysql, postgres, oracle, cybase etc. from your erlang application using the Erlang ODBC interface is a good way to go about it."[0]
"It is built on top of Microsofts ODBC interface and therefore requires that you have an ODBC driver to the database that you want to connect to."[0]
"But currently it is only regularly tested for sqlserver and postgres."[1]
"But currently it is only tested for Solaris, Windows 2000, Windows XP and NT"[2]
