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);
