1 装载数据库的JDBC驱动程序
Class.forName(“sun.jdbc.odbc.JdbcOdbcDriver”);
2 建立与数据库的连接
Connection con=java.sql.DriverManager.getConnection(JDBC URL,用户名,密码) ;
3 创建Statement或PrepareStatement对象
Statement stmt = con.createStatement();
PrepareStatement prepStmt =con.prepareStatement(selectStatement);
4 调用SQL语句
String sql = “select id,name,title,price from books where=‘Tom’ and price=40”;
ResultSet rs=stmt.executeQuery(sql);
5 访问ResultSet
while(rs.next())
{
 String col1 = rs.getString(1);
 String col2 = rs.getString(2);
 String col3 = rs.getString(3);
 float col4 = rs.getFloat(4);
}
6 依次关闭ResultSet,Statement,Connection对象
rs.close();
stmt.close();
con.close();
