数据库连接串

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


2、DB2数据库
Class.forName("com.ibm.db2.jdbc.app.DB2Driver ");
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);


3、MySQL数据库
Class.forName("org.gjt.mm.mysql.Driver");
String url ="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicode=true&characterEncoding=8859_1"
//myDB为数据库名
Connection conn= DriverManager.getConnection(url);




4.Sql Server7.0/2000数据库 
//import java.sql.*; 
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 
//String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=db2"; //7.0、2000 
String url="jdbc:sqlserver://localhost:1433;DatabaseName=db2"; //2005  //db2为数据库名 
String user="sa"; 
String password=""; 
Connection conn= DriverManager.getConnection(url,user,password);  
Statement stmtNew=conn.createStatement();


5.Sybase数据库 
//import java.sql.*; 
Class.forName("com.sybase.jdbc.SybDriver"); 
String url =" jdbc:sybase:Tds:localhost:5007/myDB";//myDB为你的数据库名 
Properties sysProps = System.getProperties(); 
SysProps.put("user","userid"); 
SysProps.put("password","user_password"); 
Connection conn= DriverManager.getConnection(url, SysProps);  
Statement stmtNew=conn.createStatement();


6.本地连接
MySQL
Class.forName("com.mysql.jdbc.Driver");
String url= "jdbc:mysql://localhost:3306/zmj?useUnicode=true&characterEncoding=utf8";
Connection conn = DriverManager.getConnection(url,"root","root");
