JAVA连接数据库综合篇：Java连接各种数据库的实例
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 "
//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);
