连接各种数据库写法

1 、Oracle8 / 8i / 9i数据库（thin模式） 
Class.forName( " oracle.jdbc.driver.OracleDriver " ).newInstance(); 
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  " ).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 、Sql Server7. 0 / 2000数据库 
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 、Sybase数据库 
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); 

5 、Informix数据库 
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); 

6 、MySQL数据库 
Class.forName( " org.gjt.mm.mysql.Driver " ).newInstance(); 
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); 

7 、PostgreSQL数据库 
Class.forName( " org.postgresql.Driver " ).newInstance(); 
String url  = " jdbc:postgresql://localhost/myDB "  
// myDB为数据库名 
String user = " myuser " ; 
String password = " mypassword " ; 
Connection conn =  DriverManager.getConnection(url,user,password);
