Java 如何连接 SQL 2008 R2

前提：

1. 复制sqljdbc_auth.dll到C:\Windows\System32这个路径下。

2. 添加sqljdbc4.jar到Libraries里面。

代码示例：

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.sql.Statement;

public class Connsql2008R2 {
    /***
     * @param args
     * @throws ClassNotFoundException
     * @throws IllegalAccessException
     * @throws InstantiationException
     * @throws SQLException
     */
    public static void main(String[] args) throws InstantiationException,
            IllegalAccessException, ClassNotFoundException, SQLException {
        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver")
                .newInstance();
        System.out.println("数据库驱动程序注册成功！");
        String url = "jdbc:sqlserver://servername;integratedSecurity=true;";
        String user = "域名\\帐号";
        String password = "密码";
        Connection conn = DriverManager.getConnection(url, user, password);
        System.out.println("数据库连接成功");
        String query = "select top 1 columnname from DB..TableName where CustomerID='13671980222' and IsDeleted=0 order by datachange_lasttime desc";
        Statement stmt = conn.createStatement();
        ResultSet rs = stmt.executeQuery(query);
        ResultSetMetaData rm;
        rm = rs.getMetaData();
        int columnNum = rm.getColumnCount();
        while (rs.next()) {
            for (int i = 1; i <= columnNum; i++) {
                System.out.print(rs.getString(i));
            }
            System.out.println();
        }
    }
}
