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:mydb"; //mydb为数据库的SID
String user="XXX";
String password="XXXX";
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/mydb"; //mydb为你的数据库名
String user="XXXX";
String password="XXXX";
Connection conn= DriverManager.getConnection(url,user,password);

3、Sql Server7.0/2000/2005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="XXX";
String password="XXX";
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","XXX");

SysProps.put("password","XXXX");
Connection conn= DriverManager.getConnection(url, SysProps);

5、Informix数据库

Class.forName("com.informix.jdbc.IfxDriver").newInstance();
String url = "jdbc:informix-sqli://localhost:1533/myDB:INFORMIXSERVER=mydb;
user=XXX;password=XXXX"; //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=XXX&password=XXX&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="XXX";
String password="XXXXX";
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/mydb.mdb");
Connection conn = DriverManager.getConnection(url,"","");
Statement stmtNew=conn.createStatement() ;
