淺談JDBC連接數據庫

      JDBC怎麼連接數據庫？Java數據庫連接（JDBC）由一組用Java編程語言編寫的類和接口組成。JDBC 爲工具/數據庫開發人員提供了一個標準的 API，使他們能夠用純Java API 來編寫數據庫應用程序。本文主要集合了不同數據庫的連接方式。　　

1、Oracle8/8i/9i數據庫(thin模式)

      1. Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();  

      2. Stringurl="jdbcracle:thinlocalhost:1521rcl";                                                                  //orcl爲數據庫的SID

      3. Stringuser="test";  

      4. Stringpassword="test";  

      5.Connectionconn=DriverManager.getConnection(url,user,password); 

 

2、DB2數據庫

      1. Class.forName("com.ibm.db2.jdbc.app.DB2Driver").newInstance();        

      2. Stringurl="jdbc:db2://localhost:5000/sample";                                                             //sample爲你的數據庫名  

      3. Stringuser="admin";  

      4. Stringpassword = "";

      5. Connectionconn=DriverManager.getConnection(url,user,password); 

 

3、SqlServer7.0/2000數據庫

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

      2. Stringurl="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb";              //mydb爲數據庫

      3. Stringuser="sa";  

      4. Stringpassword="";  

      5. Connectionconn=DriverManager.getConnection(url,user,password); 

 

4、Sybase數據庫

      1. Class.forName("com.sybase.jdbc.SybDriver").newInstance();  

      2. Stringurl="jdbc:sybase:Tds:localhost:5007/myDB";                                                      //myDB爲你的數據庫名

      3. PropertiessysProps=System.getProperties();  

      4. SysProps.put("user","userid");  

      5. SysProps.put("password","user_password");  

      6. Connectionconn=DriverManager.getConnection(url,SysProps); 

 

5、Informix數據庫

      1. Class.forName("com.informix.jdbc.IfxDriver").newInstance();  

      2. Stringurl="jdbc:informix-sqli://123.45.67.89:1533/myDB:INFORMIXSERVER=myserver;  

      3. user=testuser;password=testpassword";                                                                   //myDB爲數據庫名  

      4. Connectionconn=DriverManager.getConnection(url); 

 

6、MySQL數據庫

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

      2. Stringurl="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicode=true&characterEncoding=8859_1"                  //myDB爲數據庫名

      3. Connectionconn=DriverManager.getConnection(url); 

 

7、PostgreSQL數據庫

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

      2. Stringurl="jdbc:postgresql://localhost/myDB"                                                               //myDB爲數據庫名

      3. Stringuser="myuser";  

      4. Stringpassword="mypassword";  

      5. Connectionconn=DriverManager.getConnection(url,user,password); 

 

8、access數據庫直連用ODBC

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

      2. Stringurl="jdbcdbcriver={MicroSoftAccessDriver(*.mdb)};DBQ="+application.getRealPath("/Data/ReportDemo.mdb");   

      3. Connectionconn=DriverManager.getConnection(url,"","");  

      4. StatementstmtNew=conn.createStatement();
