图12-12 导入db_ilike.mdb数据库(1)
图12-13 导入db_ilike.mdb数据库(2)
(2)在Myeclipse中新建Web项目,导入SQLserver对应的驱动程序包,如图12-14所示。

图12-14 导入SQL驱动程序包
(3)新建supplier_edit.jsp,使用小脚本加载对应的数据库驱动,注意驱动字符串的拼写,不同数据库的驱动字符串是不一样的,格式一般在数据库厂商的网站上可以查询得到,例如:SQLserver数据库2008的加载驱动的语句如下。
Class.forName(\);
使用DriverManager类的getConnection方法获取连接对象,getConnection方法的主要参数有数据库的URL访问地址,数据库名,访问数据库的账户名,登录数据库使用的密码。
Connection con = DriverManager.getConnection
(\2345;\);
利用得到的Connection对象生成Statement对象,查询数据库后的结果在JSP页面上显示,supplier_edit.jsp的完整代码如下。
源代码:
<%@ page contentType=\%> <%@ page import=\ %>
<%
long supplierID=1; try{
Class.forName(\);
Connection con =
DriverManager.getConnection(\ilike;user=sa;password=12345;\);
12
Statement dbc = con.createStatement();
String sqlStmt= \
supplierChargeName,supplierPhone,supplierEmail,supplierQQ,supplierRemark from supplier_tb where supplierID= \+supplierID;
%>
ResultSet rs= dbc.executeQuery(sqlStmt); rs.next();
String supplierName=rs.getString(1); String supplierAddress=rs.getString(2); String supplierChargeName=rs.getString(3); String supplierPhone =rs.getString(4); String supplierEmail =rs.getString(5); String supplierQQ =rs.getString(6); String supplierRemark=rs.getString(7); rs.close();

<% dbc.close(); }catch(Exception e1) {out.println(e1.toString());}

(4)编写m_supplier_edit.jsp实现数据库信息修改功能。
源代码:
<%@ page contentType=\ %> <%@ page import=\ %>
<%request.setCharacterEncoding(\);%> <%
String supplier_id =
request.getParameter(\)==null?\:request.getParameter(\er_id\);
long fID = Long.parseLong(supplier_id); String supplier_name =
request.getParameter(\)==null?\:request.getParameter(\lier_name\);
String supplier_address =
request.getParameter(\)==null?\:request.getParameter(%upplier_address\);
String supplier_chargeName =
request.getParameter(\)==null?\:request.getParameter(\);
String supplier_phone =
request.getParameter(\)==null?\:request.getParameter(\plier_phone\);
String supplier_email =
request.getParameter(\)==null?\:request.getParameter(\plier_email\);
String supplier_QQ =
request.getParameter(\)==null?\:request.getParameter(\er_QQ\);
String supplier_remark =
request.getParameter(\)==null?\:request.getParameter(\pplier_remark\);
String sql=\
\\'\+supplier_name+\+supplier_address+\argeName= \\'\+supplier_chargeName+\
\\'\+supplier_phone+\+supplier_email+\\\'\+supplier_QQ+\\\'\+supplier_remark+\where supplierID = \+ fID;
