如何將各種數據庫連接起來？

1、Oracle8/8i/9i數據庫（thin模式）

Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();

String url="jdbc:Oracle:thin:@localhost:1521:orcl"; //orcl為數據庫的SID

String user="test";

String passWord="test";

Connection conn= DriverManager.getConnection(url,user,passWord);

2、DB2數據庫

Class.forName("com.ibm.db2.jdbc.app.DB2Driver ").newInstance();

String url="jdbc:db2://localhost:5000/sample"; //sample為你的數據庫名

String user="admin";

String passWord="";

Connection conn= DriverManager.getConnection(url,user,passWord);

3、SQL Server7.0/2000數據庫

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();

String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb";

//mydb為數據庫

String user="sa";

String passWord="";

Connection conn= DriverManager.getConnection(url,user,passWord);

4、Sybase數據庫

Class.forName("com.Sybase.jdbc.SybDriver").newInstance();

String url =" jdbc:Sybase:Tds:localhost:5007/myDB";//myDB為你的數據庫名

Properties sysProps = System.getPropertIEs();

SysProps.put("user","userid");

SysProps.put("password","user_passWord");

Connection conn= DriverManager.getConnection(url, SysProps);

5、Informix數據庫

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為數據庫名

Connection conn= DriverManager.getConnection(url);

6、MySQL數據庫

Class.forName("org.gjt.mm.MySQL.Driver").newInstance();

//或者Class.forName("com.MySQL.jdbc.Driver");

String url ="jdbc:MySQL://localhost/myDB?

user=soft&passWord=soft1234&useUnicode=true&characterEncoding=8859_1"

//myDB為數據庫名

Connection conn= DriverManager.getConnection(url);

7、PostgreSQL數據庫

Class.forName("org.postgresql.Driver").newInstance();

String url ="jdbc:postgresql://localhost/myDB" //myDB為數據庫名

String user="myuser";

String password="mypassWord";

Connection conn= DriverManager.getConnection(url,user,passWord);

8、Access數據庫直連用ODBC的

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") ;

String url="jdbc:odbc:Driver={MicroSoft Access Driver

(*.mdb)};DBQ="+application.getRealPath("/Data/ReportDemo.mdb");

Connection conn = DriverManager.getConnection(url,"","");

Statement stmtNew=conn.createStatement() ;
