JDBC数据库连接

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(数据库的SID)  或者 为mes
String user="system"; 
String password="saas"; 
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="123456"; 

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

3.1、Sql Server2005数据库 
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="123456"; 
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();       //com.mysql.jdbc.Driver
String url ="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicode=true&characterEncoding=UTF-8" 
//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、access数据库直连用ODBC的
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,"","");
Statement stmtNew=conn.createStatement() ;




Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") ;
String sConnStr="jdbc:odbc:mydb";
//String url="jdbc:odbc:Driver={MicroSoft Access Driver (*.mdb)};DBQ="+"mydb.mdb";
Connection conn = DriverManager.getConnection(sConnStr);
Statement st=conn.createStatement();
String sql="select * from user_info";
ResultSet rs=st.executeQuery(sql);
while(rs.next()){
System.out.println(rs.getString("name"));
}
