键槽刨刀:JAVA连接各种数据库

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);
