数据库连接

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();

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

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);

8、access数据库直连用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() ;
