java连接数据库驱动和url

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"
Class.forName("com.mysql.jdbc.Driver").newInstance();
String url ="jdbc:mysql://localhost:3306/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();
