------解决方案--------------------
Class.forName( "com.informix.jdbc.IfxDriver ").newInstance();
String url = "jdbc:informix-sqli://123.45.67.89:1533/testDB:INFORMIXSERVER=myserver;
user=testuser;password=testpassword ";
//testDB为你的数据库名,myserver是你数据库服务器名字
Connection conn= DriverManager.getConnection(url);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql= "select * from test ";
ResultSet rs=stmt.executeQuery(sql);
还需要informix 的jdbc开发包
没有我可以发给你.留下mail
------解决方案--------------------
一、jsp连接Oracle8/8i/9i数据库(用thin模式)
testoracle.jsp如下:
<%@ page contentType= "text/html;charset=gb2312 "%>
<%@ page import= "java.sql.* "%>
<html>
<body>
<%Class.forName( "oracle.jdbc.driver.OracleDriver ").newInstance();
String url= "jdbc:oracle:thin:@localhost:1521:orcl ";
//orcl为你的数据库的SID
String user= "scott ";
String password= "tiger ";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql= "select * from test ";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()) {%>
您的第一个字段内容为: <%=rs.getString(1)%>
您的第二个字段内容为: <%=rs.getString(2)%>
<%}%>
<%out.print( "数据库操作成功,恭喜你 ");%>
<%rs.close();
stmt.close();
conn.close();
%>
</body>
</html>
二、jsp连接Sql Server7.0/2000数据库
testsqlserver.jsp如下:
<%@ page contentType= "text/html;charset=gb2312 "%>
<%@ page import= "java.sql.* "%>
<html>
<body>
<%Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver ").newInstance();
String url= "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=pubs ";
//pubs为你的数据库的
String user= "sa ";
String password= " ";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql= "select * from test ";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()) {%>
您的第一个字段内容为: <%=rs.getString(1)%>
您的第二个字段内容为: <%=rs.getString(2)%>
<%}%>
<%out.print( "数据库操作成功,恭喜你 ");%>
<%rs.close();
stmt.close();
conn.close();
%>
</body>
</html>
三、jsp连接DB2数据库
testdb2.jsp如下:
