One of the most fundamental things that you'll do with the Microsoft JDBC Driver for SQL Server is to make a connection to a SQL Server database. All interaction with the database occurs through the SQLServerConnection object, and because the JDBC driver has such a flat architecture, almost all interesting behavior touches the SQLServerConnection object.
If a SQL Server is only listening on an IPv6 port, set the java.net.preferIPv6Addresses system property to make sure that IPv6 is used instead of IPv4 to connect to the SQL Server:
System.setProperty("java.net.preferIPv6Addresses", "true");
The articles in this section describe how to make and work with a connection to a SQL Server database.
