String sql = "select * from test"; // SQL 字符串 7. 8. // 连接字符串，格式： "jdbc:数据库驱动名称:连接模式:@数据库服务器ip:端口号:数据库SID" 9. String url = "jdbc:oracle:thin:@localhost:1521:orcl"; 10. String username = "scott"; // 用户名 11. String password = "tiger"; //密码 12. 13. // 创建oracle数据库驱动实例 14. Class.forName("oracle.jdbc.driver.OracleDriver").newInstance(); 15. 16. // 获得与数据库的连接 17. Connection conn = DriverManager.getConnection(url, username, password); 18. // 创建执行语句对象 19. Statement stmt = conn.createStatement(); 20. // 执行sql语句，返回结果集 21. ResultSet rs = stmt.executeQuery(sql); 22. 23. while ( rs.next() ) 24. { 25. result += "/n 第一个字段内容：" + rs.getString(1) + "<BR>"; 26. } 27. 28. rs.close(); // 关闭结果集 29. stmt.close(); // 关闭执行语句对象 30. conn.close(); // 关闭与数据库的连接 31. %> 32. 33. <HTML> 34. <BODY> 35. <%=result%> 36. </BODY> 37. </HTML> <%@ page contentType="text/html;charset=gb2312"%><%@ page import="java.sql.*"%><% String result = ""; // 查询结果字符串 String sql = "select * from test"; // SQL 字符串 // 连接字符串，格式： "jdbc:数据库驱动名称:连接模式:@数据库服务器ip:端口号:数据库SID" String url = "jdbc:oracle:thin:@localhost:1521:orcl"; String username = "scott"; // 用户名 String password = "tiger"; //密码 // 创建oracle数据库驱动实例 Class.forName("oracle.jdbc.driver.OracleDriver").newInstance(); // 获得与数据库的连接 Connection conn = DriverManager.getConnection(url, username, password); // 创建执行语句对象 Statement stmt = conn.createStatement(); // 执行sql语句，返回结果集 ResultSet rs = stmt.executeQuery(sql); while ( rs.next() ) { result += "/n 第一个字段内容：" + rs.getString(1) + "<BR>"; } rs.close(); // 关闭结果集 stmt.close(); // 关闭执行语句对象 conn.close(); // 关闭与数据库的连接%> <HTML><BODY> <%=result%></BODY></HTML>二、jsp连接Sql Server7.0/2000数据库testSqlServer.jsp如下Java代码 1. <%@ page contentType="text/html;charset=gb2312"%> 2. <%@ page import="java.sql.*"%> 3. <% 4.
