请教jdbc数据库连接问题?
执行以下程序代码:
mybag.inc文件代码如下:
<%@ page import= "java.sql.* "%>
<%@ page import= "java.util.* "%>
<%@ page import= "java.io.* "%>
<%@ page import= "com.microsoft.jdbc.sqlserver.SQLServerDriver "%>
<%@ page import= "java.lang.* "%>
<%@ page contentType= "text/html; charset=gb2312 "%>
<%
request.setCharacterEncoding( "gb2312 ");
String CLASSFORNAME= "com.microsoft.jdbc.sqlserver.SQLServerDriver ";
String SERVANDDB= "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=school ";
String USER= "sa ";
String PWD= "sa ";
%>
chaxun.jsp文件代码如下:
<%@ include file= "mybag.inc "%>
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=gb2312 ">
<title> 无标题文档 </title>
</head>
<body>
<%
//获得请求的参数。
String id=request.getParameter( "tuser ");
String psw=request.getParameter( "pwd ");
//连接数据库
Class.forName(CLASSFORNAME);
Connection con = DriverManager.getConnection(SERVANDDB,USER,PWD);
Statement statement=con.createStatement();
String isCorrect= "select * from users where userid= ' " + id + " ' and password= ' " + psw + " ' ";
ResultSet result=statement.executeQuery(isCorrect);
out.print(result.getString( "username "));
%>
</body>
</html>
