Java连接各种数据库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(); //或者Class.forName("com.mysql.jdbc.Driver"); 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); 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() ;
