java 连接sqlserver数据库，并执行sql语句
public class LinkDB {
public static void main(String[] args) {
List<String> list = connect();
}
//连接数据库执行语句
private static List<String> connect() {
List<String> arr = new ArrayList<String>();

String url = "jdbc:sqlserver://ip:port;database=数据库名";
String user = "用户名";
String password = "密码";
Connection con = DriverManager.getConnection(url, user, password);
Statement statement = con.createStatement();
ResultSet re = statement.executeQuery("SELECT DISTINCT name FROM table");//执行查询语句，接收结果集
while (re.next()) {
arr.add(re.getString("name"));
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
