Java Web連接各種數據庫方式匯總

1.Oracle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";simple 為你的數據庫名

String user="admin";

String password="";

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

 

3.Sql Server 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="123456";

Connnection 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://ip地址/myDB:INFORMIXSERVER=myserver;user=testuser;password=testpassword";

Connection conn=DriverManager.getConnection(url);

 

6.MySQL數據庫

Class.forName('org.git.mm.mysql..Driver').newInstance();

String url="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicode=truecharacterEncoding=8859_1";//myDB為數據庫名

Connection conn=DriverManager.getConnection(url);

 

7.access數據庫

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

String url="jdbc:odbc:Driver={Microsoft Access Driver(*.mdb)};DBQ="+application.getRealPath("/Data/ReportDemo.mdb");

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

 

操作數據庫方法

String sql=" ";

Statement st=conn.createStatement();

ReusltSet rs=st.executeQuery(sql);
