java连接sqlserver2008

java连接sqlserver2008时应有sqljdbc4.jar驱动包。连接的示例代码如下：

import java.sql.*;

public class ConnectSQL {

	public static void main(String[] args) {

		try{
		  String driver="com.microsoft.sqlserver.jdbc.SQLServerDriver";
		  Class.forName(driver); //加载驱动
		  String url="jdbc:sqlserver://localhost:1433;"+
		  "DatabaseName=UserInfo";
		  Connection conn=DriverManager.getConnection(url,"sa","123");//建立连接
		  Statement stmt=conn.createStatement();//创建状态
		  String sql="select * from userInfo";
		  ResultSet rs=stmt.executeQuery(sql);//执行查询
		  while(rs.next()){
			  System.out.println(rs.getInt(1)+","+rs.getString(2)+","+
		  rs.getString(3)+","+rs.getInt(4)+","+rs.getInt(5));
		  }
		  rs.close();
		  stmt.close();
		  conn.close();//善后
		}
		catch(Exception e){
			e.printStackTrace();
		}

	}
