JDBC连接各种数据库

1.与Oracle连接

Class.forName("oracle.jdbc.driver.OracleDriver").newInstance(); 
String url="jdbc:oracle:thin:@localhost:1521:orcl"; //orcl为数据库SID 
String user="test"; 
String password="test"; 
Connection conn= DriverManager.getConnection(url,user,password); 

2.与DB2连接

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); 

3.与SQL Server连接

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance(); 
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb"; 
//mydb为数据库 
String user="sa"; 
String password=""; 
Connection conn= DriverManager.getConnection(url,user,password); 

4.与MySql连接

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

5.与Sybase连接

Class.forName("com.sybase.jdbc.SybDriver").newInstance(); 
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); 

6.与Informix连接

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为数据库名 
Connection conn= DriverManager.getConnection(url);

7.与access连接

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() ;
