Connecting to SQL Server with the JDBC driver

Download JDBC driver

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.
