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();
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() ;
