（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;\);

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();

（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;

try{

Class.forName(\);

Connection con =

DriverManager.getConnection(\
