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();

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、JDBC-ODBC桥

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

Connection con=DriverManager.getConnection("jdbc:odbc:jsp");

jsp为建立的odbc数据源名，事先要先将SQL server的表设置为数据源。在“管理工具”-“数据源odbc”里用系统DNS添加。

 

8.Oracle8/8i/9i数据库（thin模式）

//import java.sql.*;

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); 

Statement stmtNew=conn.createStatement();

9.DB2数据库

//import java.sql.*;

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); 

Statement stmtNew=conn.createStatement();

10.Sql Server7.0/2000数据库

//import java.sql.*;

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

//String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=db2"; //7.0、2000

String url="jdbc:sqlserver://localhost:1433;DatabaseName=db2"; //2005

//db2为数据库名

String user="sa";

String password="";

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

Statement stmtNew=conn.createStatement();

11.Sybase数据库

//import java.sql.*;

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); 

Statement stmtNew=conn.createStatement();

12.Informix数据库

//import java.sql.*;

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); 

Statement stmtNew=conn.createStatement();

13.MySQL数据库

//import java.sql.*;

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

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

//String url ="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicode=true&characterEncoding=8859_1";

String url ="jdbc:mysql://localhost:3306/myDB";

//myDB为数据库名

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

Statement stmtNew=conn.createStatement();

14.PostgreSQL数据库

//import java.sql.*;

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);

Statement stmtNew=conn.createStatement();

15.access数据库直连用ODBC的

//import java.sql.*;

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,"sa","");

Statement stmtNew=conn.createStatement();

16.程序计时

long time1=System.currentTimeMillis();

long time2=System.currentTimeMillis();

long interval=time2-time1;

17.延时

try {

Thread.sleep(Integer.Parse(%%1));

} catch(InterruptedException e) {

e.printStackTrace();

}

18.连接Excel文件

//import java.sql.*;

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

String url = "jdbc:odbc:driver={Microsoft Excel Driver (*.xls)};DBQ=D:\\myDB.xls"; // 不设置数据源

String user="myuser";

String password="mypassword";

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

Statement stmtNew=conn.createStatement();
