java 连接各种数据库 总结

 

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、SqlServer7.0/2000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);

 

驱动：

msbase.jar

mssqlserver.jar

msutil.jar

 

 

sqlserver 2005

 

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance(); String url="jdbc:sqlserver://localhost:1433;DatabaseName=mydb"; //mydb为数据库 String user="sa"; String password=""; Connection conn= DriverManager.getConnection(url,user,password);

 

驱动：sqljdbc.jar

 

 

 

 

 

 

 

 

4、Sybase数据库

Java连接Sybase数据库
第一步：工欲善其事，必先利其器。（下载驱动）
下载JDBC驱动：
网址：http://www.sybase.com/detail?id=1009726
有jConnect6.0和jConnect5.5两种，我们下载6.0版本。

第二步：得到驱动
释放下载的jConnect-6_0.zip文件，其中有文件夹：devclasses，其下有一jar文件jconn3d。我们将jconn3d.jar也释放，其实可以不释放，为了说明简便，我们将它释放到任意文件夹，比如：c:/Driver.

第三步：设置环境变量
将上述所释放的位置目录，如c:/Driver追加到环境变量classpath的尾部。

第四步：万事俱备，只欠东风
所有的准备工作都已完成，下面就可以开始编程。我们以一个简单的数据库查询为例：
import com.sybase.jdbc3.jdbc.SybDriver; 
import java.sql.*; 
import java.io.*; 
import java.util.*;
public class ConnTest{
 public static void main(String[] args){
  try{
  Class.forName("com.sybase.jdbc3.jdbc.SybDriver").newInstance(); 
  String url ="jdbc:sybase:Tds:192.168.100.252:4500/myDB";//myDB为你的数据库名 
  Properties sysProps = System.getProperties(); 
  sysProps.put("user","user_id");  //设置数据库访问用户名
  sysProps.put("password","user_pwd");  //密码
  Connection conn= DriverManager.getConnection(url, sysProps); 
    Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
    String sql="select * from userInfo";  //userInfo为其中的一个表
    ResultSet rs=stmt.executeQuery(sql);
    while(rs.next()) {
     System.out.println(rs.getString(2));   //取得第二列的值 
    }
  }catch(Exception e)
  {
   out.println(e.getMessage());
  }
 }
}

 

 

 

 

 

 

 

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

驱动为mysql.jar
  String url ="jdbc:mysql://localhost/jpt?user=root&password=root&useUnicode=true&characterEncoding=8859_1" ;
   //myDB为数据库名 Connection conn= DriverManager.getConnection(url);
  Connection dbConn=null;
  try {
   Class.forName("com.mysql.jdbc.Driver").newInstance();
  } catch (ClassNotFoundException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } catch (InstantiationException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } catch (IllegalAccessException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  try {
   dbConn = DriverManager.getConnection(url);
   
    Statement stmt = null;         //数据库表达式
          ResultSet rs = null;             //结果集
       stmt = dbConn.createStatement();
      
          //4. 执行SQL
         // rs = stmt.executeQuery("SELECT 序号 AS ID , 车号 AS CH,日期 AS RQ, 时间 AS SJ,毛重 AS MZ,皮重 AS PZ,净重 JZ, 发货 AS FZ,收货 AS DZ, 货名 AS RLCP, 扣杂 AS KGL ,台号 AS HQH FROM SAVER  where 序号>'300026876' ");
       rs = stmt.executeQuery("SELECT * FROM zz_userlist ");
       SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
          //5. 现实结果集里面的数据
       java.sql.ResultSetMetaData md = rs.getMetaData();
          while(rs.next()) {
            System.out.print("\n");
            for(int i=1; i<= md.getColumnCount(); i++) {
              System.out.print(rs.getString(i) + " | ");
            }
          }
          rs.close();
    
  } catch (SQLException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  System.out.println("Connection Successful!");
   

 

 

 

 

 

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：paradox 数据库

它有很多种连接方式，ftp,共享，IP，本机连接

HXTT Paradox provides a type 4 JDBC driver for Paradox version from 3.0, 3.5, 4.x, 5.x, 7.x to 11.x. It supports JDBC1.2, JDBC2.0, JDBC3.0, and JDBC4.0. It supports Personal Java, JDK1.0.X, JDK1.1.X, JDK1.2.X, JDK1.3.X, JDK1.4.X, JDK1.5.X, and JDK1.6.X. It supports JBuilder's Database Pilot, Oracle's JVM, JDeveloper 10G, Dreamweaver UltraDev, Dreamweaver ColdFusion, ObJectRelationalBridge, DBVisualizer, iSQL-Viewer, AquaDataStudio, Sunopsis, MySQL Migration Toolkit, Tomcat, vqServer, Hibernate, SQuirreL SQL Client, Crystal Reports, Jisql, and DbEdit Database Utilites for Eclipse Platform. It supports transaction, XOPEN SQLState, RMI, Jini, JNDI, and serialization. It supports { UNION | INTERSECT | EXCEPT | MINUS } [ ALL ] query , INNER JOIN, FULL JOIN, LEFT JOIN, RIGHT JOIN, NATURAL JOIN, CROSS JOIN, self join, GROUP_CONCAT, multiple-row VALUES table, PIVOT table, UNPIVOT table, and subquery which includes single-row subquery, multirow subquery, multiple-column subquery, inline views, and correlated subquery. The current version of the HXTT Paradox packages are available here:

Follow Me

First, you need to download JDK1.6.X from www.javasoft.com if you use Paradox JDBC 4.0 package(Paradox_JDBC40.jar). You can download JDK 1.3.X, 1.4.X, JDK1.5.X, or JDK1.6.X if you use Paradox JDBC 3.0 package(Paradox_JDBC30.jar) . You can download JDK1.2.X too if you use Paradox JDBC 2.0 package(Paradox_JDBC20.jar). You can download JDK1.1.X too if you use Paradox JDBC 1.2 package(Paradox_JDBC12.jar).

Secondly, please add Paradox_JDBC30.jar, Paradox_JDBC20.jar or Paradox_JDBC12.jar to your Java class path, for instance, "SET CLASSPATH=c:\javalib\Paradox_JDBC20.jar;%classpath%". You can also use "java -classpath c:\javalib\Paradox_JDBC20.jar yourParadoxclass" to run your class. More information about classpath, please read the "Setting the Classpath" topic in file:///yourdriver|/jdk1.2/docs/tooldocs/tools.html . You can use "java -classpath c:\javalib\Paradox_JDBC20.jar yourParadoxclass" too.

Thirdly, you can use 'Class.forName("com.hxtt.sql.paradox.ParadoxDriver").newInstance();' or Class.forName("com.hxtt.sql.paradox.ParadoxDriver");' to load this driver.

Fourth, if you have used other JDBC driver, you only need to know the correct URL format for DriverManager.getConnection(url,"",""); You can find the Paradox URL format below. If you were a Java novice, please read also other Java examples code in Paradox_JDBC30demo.zip, Paradox_JDBC20demo.zip or Paradox_JDBC12demo.zip.
Paradox URL format:

        Embedded:

 

 

 

 

 

 

                jdbc:paradox:[//]/[DatabasePath][?prop1=value1[;prop2=value2]] (You can omit that "//" characters sometimes)

 

 

 

 

 

 

                        For example:

 

 

 

 

 

 

                                "jdbc:paradox:/."

 

 

 

 

 

 

                                "jdbc:paradox:/c:/data" for Windows driver

 

 

 

 

 

 

                                "jdbc:paradox:///c:/data" for Windows driver

 

 

 

 

 

 

                                "jdbc:paradox:////usr/data" for unix or linux

 

 

 

 

 

 

                                "jdbc:paradox://///192.168.10.2/sharedir" for UNC path

 

 

 

 

 

 

                                "jdbc:paradox:/./data"

 

 

 

 

 

 

        Remote Access (client/server mode):

 

 

 

 

 

 

                jdbc:paradox://host:port/[DatabasePath]

 

 

 

 

 

 

                        For example: "jdbc:paradox://domain.com:3099/c:/data" if one ParadoxServer is run on the 3099 port of domain.com

 

 

 

 

 

 

        Compressed Database:(.ZIP, .JAR, .GZ, .TAR, .BZ2, .TGZ, .TAR.GZ, .TAR.BZ2)

 

 

 

 

 

 

                jdbc url format is the same as embedded url and remote url.

 

 

 

 

 

 

                        For example:

 

 

 

 

 

 

                                "jdbc:paradox:/c:/test/testparadox.zip

 

 

 

 

 

 

        Memory-only Database:

 

 

 

 

 

 

                jdbc:paradox:/_memory_/

 

 

 

 

 

 

        URL Database:(http protocol, https protocol, ftp protocol)

 

 

 

 

 

 

                jdbc:paradox:http://httpURL

 

 

 

 

 

 

                jdbc:paradox:https://httpsURL

 

 

 

 

 

 

                jdbc:paradox:ftp://ftpURL

 

 

 

 

 

 

                        For example:

 

 

 

 

 

 

                                "jdbc:paradox:http://www.hxtt.com/test" ////Note: FTP site's user/password should be set in ftpURL, and cannot be set in JDBC connection property because user/password JDBC connection property belongs to server/client connection.

 

 

 

 

 

 

        SAMBA Database:(smb protocol)

 

 

 

 

 

 

                jdbc:paradox:smb://[[[domain;]username[:password]@]server[:port]/[[share/[dir/]file]]][?[param=value]]

 

 

 

 

 

 

                        For example:

 

 

 

 

 

 

                                "jdbc:paradox:smb://test1:[email protected]/paradoxfiles".zone" ////Note: SAMBA user/password should be set in SMB URL, and cannot be set in JDBC connection property because user/password JDBC connection property belongs to server/client connection.

 

 

 

 

 

 

        Free JDBC url:(Warning: only use it for special project)

 

 

 

 

 

 

                jdbc:paradox:/" or "jdbc:paradox:///". Then you can use some full UNC path names in SQL to visit anywhere where your Java VM has right to access.

 

 

 

 

 

 

                        For instance:

 

 

 

 

 

 

                                select * from \\amd2500\e$\paradoxfiles\test;

 

 

 

 

 

 

                                elect * from "\\amd2500\d$\paradoxiles".test;

 

 

 

 

 

 

                                select * from ".".test;

 

 

 

 

 

 

 

 

 

 

 

 

 

         HXTT Paradox supports seamlessly data mining on memory-only table, physical table, url table, compressed table, SAMBA table in a sql. More details

 

 

 

 

 

 

         is in Advanced Programming chapter.

 

 

 

 

 

 

 

 

 

 

 

 

 

Last, Paradox driver is a standard JDBC driver so that you will find most of valuable information at file:///yourdrive|/jdk1.2/docs/api/java/sql/package-frame.html .

Paradox supports SQL-92. It supports { UNION | INTERSECT | EXCEPT | MINUS } [ ALL ] query , INNER JOIN, FULL JOIN, LEFT JOIN, RIGHT JOIN, NATURAL JOIN, CROSS JOIN, self join, GROUP_CONCAT, and subquery which includes single-row subquery, multirow subquery, multiple-column subquery, inline views, and correlated subquery. The major syntax is listed at here.

Paradox driver will use index to speed up the query which contains some indexed expressions. Paradox supports utilizing index file for LIKE, BETWEEN, IN, DISTINCT, ORDER, and some OR operations.

9:access数据库

转载：http://blog.csdn.net/qwerasdf123/archive/2009/06/30/4309383.aspx

 

 

 

 

  直接在JAVA代码内部与Access数据库连接

 

注意:jdbc:odbc:driver={Microsoft Access Driver (*.mdb)};这里的空格,不能少!否则会有异常

try{ 

             

        String url = "jdbc:odbc:driver={Microsoft Access Driver (*.mdb)};PWD=123;DBQ=F:\\ge\\123.MDB";   //如果 没有密码可以不用写pwd

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

        Connection conn = DriverManager.getConnection(url); 

        System.out.println(conn); 

        Statement sta = conn.createStatement(); 

        ResultSet resu = sta.executeQuery("select * from Roche_position"); 

        if(resu.next()){ 

            System.out.println(resu.getString("cname")); 

        } 

        System.out.println("exit"); 

        }catch(Exception e){ 

            e.printStackTrace(); 

        } 

 

 

2：远程访问数据库

 

2:使用ODBC建立WINDOW数据源的方法:

 

开始

 

>>控制面板

 

>>管理工具

 

>>数据源(ODBC)

 

>>用户DSN或系统DSN

 

>>点添加

 

>>找到"Microsoft Access Driver (*.mdb)",选中,再点完成>>自定义数据源名称,可创建一个新的或选择已经有的Access数据库(.mdb)其它可以不选

 

>>确定>>确定

 

到此数据源已经建立成功

下一步

 

1、  从http://forge.ow2.org/project/showfiles.php?group_id=8&release_id=623下载RmiJdbc.jar包。

2、  配置系统环境变量。右键”计算机”——“高级”——“环境变量”，在“系统变量”中，新建变量名为CLASSPATH的系统变量，被配置其值。

CLASSPATH=%CLASSPATH%; E:\RmiJdbc\dist\lib\RmiJdbc.jar;

注意：E:\RmiJdbc\dist\lib\RmiJdbc.jar为Rmijdbc.jar放置的目录

3、  使用”win”+r组合键，输入”cmd”，调出命令提示行对话框，输入：

java org.objectweb.rmijdbc.RJJdbcServer
