package mydbproject; import java.sql.*; public class MyDB { public static void main(String[] args) { //加载驱动程序 try { //桥连接 //Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); //直接连接 Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver"); } catch (ClassNotFoundException ex) { } //连接字符串 //桥连接 //String str = "jdbc:odbc:test"; //直接连接 String str = "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=studb"; try { Connection con = DriverManager.getConnection(str,"sa","sa"); Statement sta = con.createStatement(); ResultSet res = sta.executeQuery("select * from student"); while(res.next()) { System.out.print(res.getInt(1)); System.out.print(res.getString("s_name")); System.out.print(res.getString(3)); System.out.println(); } //sta.executeUpdate("insert into student(s_name,s_sex,s_add,s_email)" + // "values('aaa',1,'aaa','aaa@126.com')"); res.close(); sta.close(); con.close(); } catch (SQLException ex1) { ex1.printStackTrace(); } } }
