JDBC連接各種數據庫方法

JDBC連接各種數據庫的方法如下：

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爲數據庫的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爲數據庫名稱

String user="admin";

String password="admin";

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

3、Sql Server 7.0/2000數據庫

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

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

String user="sa";

String password="sa";

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爲數據庫名

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://localhost:1533

/myDB:INFORMIXSERVER=myserver;user=test;password=test";  //myDB爲數據庫名

Connection conn = DriverManager.getConnection(url);

6、MySQL數據庫

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

//或Class.forName("com.mysql.jdbc.Driver").newInstance();

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

user=soft&password=soft123&useUnicode=true&characterEncoding=8859_1";   //myDB爲數據庫名

Connection conn = DriverManager.getConnection(url);

7、PostgreSQL數據庫

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

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

String user="myuser";

String password="mypassword";

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

8、access數據庫直接連用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 stmNew = conn.createStatement();
