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:
<%@ page contenttype="text/html;charset=gb2312"%>
<%@ page import="java.sql.*"%>
<html>
<body>
<%class.forname("com.ibm.db2.jdbc.app.db2driver ").newinstance();
string url="jdbc:db2://localhost:5000/sample";
//sample为你的数据库名
string user="admin";
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>
四、jsp连接informix数据库
testinformix.jsp如下:
<%@ page contenttype="text/html;charset=gb2312"%>
<%@ page import="java.sql.*"%>
<html>
<body>
<%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
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);
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>
五、jsp连接access数据库
<%@page import="java.sql.*"
import ="java.util.*"
import ="java.io.*"
import="java.text.*"
contenttype="text/html; charset=gb2312"
buffer="20kb"
%><%! int all,i,m_count;
string odbcquery;
connection odbcconn;
statement odbcstmt;
resultset odbcrs;
string username,title,content,work,email,url,time,date;
string datetime;
%>
<%
try{
class.forname("sun.jdbc.odbc.jdbcodbcdriver");
}catch (classnotfoundexception e)
{ out.print ("驱动程序不存在");
}
try{
odbcconn = drivermanager.getconnection("jdbc:odbc:db1");
odbcstmt = odbcconn.createstatement();
odbcquery="select * from book where datetime>2001-4-26 order by datetime desc";
odbcrs=odbcstmt.executequery(odbcquery);
int i=0;
while (i<130) odbcrs.next();
while (odbcrs.next())
{
//*/////////////////////////显示数据库的内容用于调试程序是用//
int ii;
try{
try{
for (ii=1;;ii++)
out.print ("<br>cloumn "+ii+" is: "+odbcrs.getstring(ii));
}catch (nullpointerexception e) {
out.print ("有空的指针");
}
}catch (sqlexception e){
}
}
odbcrs.close();
odbcstmt.close();
odbcconn.close();
}catch (sqlexception e)
{ out.print (e);
}
%>
