java连接各种数据库

再用光在博客找就行了，呵呵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); ??
