java聯接數據庫的源代碼


--------------------------------------------------------

import java.sql.*; 
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance(); //加載驅動 
String url = "jdbc:oracle:thin:@192.168.1.30:1521:sqds"; //連接哪個數據庫 
String user = "用戶名"; 
String password = "密碼"; 
Connection con = DriverManager.getConnection(url, user, password); 
Statement sm = con.createStatement(); //用來操作的對象 
ReseltSet rs = sm.executeQuery("SQL查詢語句"); 

顯不顯示JTable里面屬于JTable的范疇,和數據庫沒關系 

--------------------------------------------------------

我這里有個http://1shome.ebok.cn/ 
JM1.3.1 
表和樹的數據來源庫 

--------------------------------------------------------

這是各種數據庫鏈接的源代碼 
應該稍微修改一下就可以用的 
！ 

1、Oracle8/8i/9i數據庫（thin模式） 
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance(); 
String url="jdbc:oracle:thin:@localhost:1521:orcl"; //orcl為數據庫的SID 
String user="test"; 
String password="test"; 
Connection conn= DriverManager.getConnection(url,user,password); 


　　2、DB2數據庫 
Class.forName("com.ibm.db2.jdbc.app.DB2Driver ").newInstance(); 
String url="jdbc:db2://localhost:5000/sample"; //sample為你的數據庫名 
String user="admin"; 
String password=""; 
Connection conn= DriverManager.getConnection(url,user,password); 


　　3、Sql Server7.0/2000數據庫 
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance(); 
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb"; 
//mydb為數據庫 
String user="sa"; 
String password=""; 
Connection conn= DriverManager.getConnection(url,user,password); 


　　4、Sybase數據庫 
Class.forName("com.sybase.jdbc.SybDriver").newInstance(); 
String url =" jdbc:sybase:Tds:localhost:5007/myDB";//myDB為你的數據庫名 
Properties sysProps = System.getProperties(); 
SysProps.put("user","userid"); 
SysProps.put("password","user_password"); 
Connection conn= DriverManager.getConnection(url, SysProps); 

5、Informix數據庫 
Class.forName("com.informix.jdbc.IfxDriver").newInstance(); 
String url = "jdbc:informix-sqli://123.45.67.89:1533/myDB:INFORMIXSERVER=myserver; 
user=testuser;password=testpassword"; //myDB為數據庫名 
Connection conn= DriverManager.getConnection(url); 


　　6、MySQL數據庫 
Class.forName("org.gjt.mm.mysql.Driver").newInstance(); 
String url ="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicode=true&characterEncoding=8859_1" 
//myDB為數據庫名 
Connection conn= DriverManager.getConnection(url); 


　　7、PostgreSQL數據庫 
Class.forName("org.postgresql.Driver").newInstance(); 
String url ="jdbc:postgresql://localhost/myDB" //myDB為數據庫名 
String user="myuser"; 
String password="mypassword"; 
Connection conn= DriverManager.getConnection(url,user,password); 


　　8、access數據庫直連用ODBC的 
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") ; 
String url="jdbc:odbc:Driver={MicroSoft Access Driver (*.mdb)};DBQ="+application.getRealPath("/Data/ReportDemo.mdb"); 
Connection conn = DriverManager.getConnection(url,"",""); 
Statement stmtNew=conn.createStatement() ;
