使用JDBC连接mysql,db2等数据库

JDBC连接数据库的方法:


1 .连接Oracle 8/8i/9i/10g/11g(thin模式)

Class.forName("oracle.JDBC.driver.OracleDriver").newInstance();


String url="JDBC:oracle:thin:@localhost:1521:orcl"       //orcl为Oracle数据库的SID


String user="test";


String password="test";


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

2.连接DB2数据库

Class.forName("com.ibm.db2.jcc.DB2Driver");


String url="JDBC:db2://localhost:5000/testDb";


String user="test"; String password="test";


Connection con=DriverManager.getConnection(url,user,password);
3.连接MySQL数据库

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


String url="JDBC:mysql://localhost:8080/testDB";


String user="test"; String password="test";


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

4.连接SQL Server2000数据库


Class.forName("com.microsoft.JDBC.sqlserver.SQLServerDriver");


String url="JDBC:microsoft:sqlserver://localhost:1433;DatabaseName=testDb";


String user="test"; String password="test";


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


5.连接PostgreSQL数据库

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


String url="JDBC:postgresql://localhost/testDb";


String user="test"; String password="test";


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

6.连接Access数据库


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


String url="JDBC:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ="+application.getRealPath("/Data/testDb/mdb");


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


7.连接Sybase数据库


Class.forName("com.sybase.JDBC.SybDriver");


String url="JDBC:sybase:Tds:localhost:5007/testDb";


Properties pro=System.getProperties();


pro.put("user","userId");


pro.put("password","user_password");


Connection con=DriverManager.getConnection(url,pro);

8.连接informix数据库

Class.forName("com.informix.JDBC.ifxDriver");


String url="JDBC:informix-sqli:localhost:1533/testDb:INFORMIXSERVER=myserver"user=testUser;password=testpassword"; 
Connection con=DriverManager.getConnection(url);
