java与各种数据库连接实例大全

java与各种数据库连接实例大全：喜欢的朋友们可以收藏起来啊呀---

1、Oracle8/8i/9i数据库（thin模式）

1 Class.forName("com.ibm.db2.jdbc.app.DB2Driver ").newInstance(); 2 String url="jdbc:db2://www.ykmaiz.com:5000/sample"; 3 //sample为你的数据库名 4 String user="admin"; 5 String password=""; 6 Connection conn= DriverManager.getConnection(url,user,password);

2、DB2数据库

1 Class.forName("oracle.jdbc.driver.OracleDriver").newInstance(); 2 String url="jdbc:oracle:thin:@www.ykmaiz.com:1521:orcl"; 3 //orcl为数据库的SID 4 String user="test"; 5 String password="test"; 6 Connection conn= DriverManager.getConnection(url,user,password);

3、Sql Server7.0/2000数据库

1 Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance(); 2 String url="jdbc:microsoft:sqlserver://www.ykmaiz.com:1433;DatabaseName=mydb"; 3 //mydb为数据库 4 String user="sa"; 5 String password=""; 6 Connection conn= DriverManager.getConnection(url,user,password);

4、Sybase数据库 

1 Class.forName("com.sybase.jdbc.SybDriver").newInstance(); 2 String url =" jdbc:sybase:Tds:www.ykmaiz.com:5007/myDB"; 3 //myDB为你的数据库名 4 Properties sysProps = System.getProperties(); 5 SysProps.put("user","userid"); 6 SysProps.put("password","user_password"); 7 Connection conn= DriverManager.getConnection(url, SysProps);

5、Informix数据库

1 Class.forName("com.informix.jdbc.IfxDriver").newInstance(); 2 String url = "jdbc:informix-sqli://www.ykmaiz.com:1533/myDB: 3 INFORMIXSERVER=myserver; user=testuser;password=testpassword"; 4 //myDB为数据库名 5 Connection conn= DriverManager.getConnection(url);

6、MySQL数据库

1 Class.forName("org.gjt.mm.mysql.Driver").newInstance(); 2 String url ="jdbc:mysql://www.ykmaiz.com/myDB?user=soft& 3 password=soft1234&useUnicode=true&characterEncoding=8859_1" 4 //myDB为数据库名 5 Connection conn= DriverManager.getConnection(url);

7、PostgreSQL数据库

1 Class.forName("org.postgresql.Driver").newInstance(); 2 String url ="jdbc:postgresql://www.ykmaiz.com/myDB" 3 //myDB为数据库名 4 String user="myuser"; 5 String password="mypassword"; 6 Connection conn= DriverManager.getConnection(url,user,password);

8、access数据库直连用ODBC的

1 Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") ; 2 String url="jdbc:odbc:Driver={MicroSoft Access Driver (*.mdb)}; 3 DBQ="+application.getRealPath("/Data/ReportDemo.mdb"); 4 Connection conn = DriverManager.getConnection(url,"",""); 5 Statement stmtNew=conn.createStatement() ;

Java与Oracle的两种连接方式。

第一种方式：通过数据库本身的JDBC Driver连接到数据库：

1 Classs.forName("oracle.jdbc.driver.OracleDriver"); 2 3 Connection conn = DriverManager.getConnection("jdbc:oracle:thin:" 4 +"@www.ykmaiz.com:1521:dbname","username","password"); 5 6 //www.ykmaiz.com为数据源

第二种方式：通过JDBC-ODBC桥连接到多级泵数据库:

01 Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); 02 03 Connection conn = DriverManager.getConnection("jdbc:odbc:www.ykmaiz.com","username","password"); 04 05 //www.ykmaiz.com为数据源 06 07 //完整的用户登录 08 09 Properties props = new Properties(); 10 11 props.put("username", "ykmaiz"); 12 13 props.put("password", "ykmaiz"); 14 15 Driver myDriver = (Driver) Class.forName("oracle.jdbc.driver.OracleDriver").newInstance(); 16 17 conn = myDriver.connect("jdbc:oracle:thin:@www.ykmaiz.com:1521:dbname", props); 18 19 conn.close(); 20 21 System.out.println("成功登录."); 22 23 System.out.println("欢迎您 "+props.getProperty("username")+"!");
