各種數據庫的連接代碼

各種數據庫的連接代碼

1、Sql Server2000數據庫
Class.forName('com.microsoft.jdbc.sqlserver.SQLServerDriver').newInstance();
String url='jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb';
//mydb爲數據庫
String user='sa';
String password='';
Connection conn= DriverManager.getConnection(url,user,password);
2、MySQL數據庫
Class.forName('org.gjt.mm.mysql.Driver').newInstance(); //或者Class.forName('com.mysql.jdbc.Driver');
String url ='jdbc:mysql://localhost:3306/myDB?user=soft&password=soft1234&useUnicode=true&characterEncoding=8859_1'
//myDB爲數據庫名
Connection conn= DriverManager.getConnection(url);
3、Oracle8/8i/9i數據庫（thin模式）
Class.forName('oracle.jdbc.driver.OracleDriver').newInstance();
String url='jdbc: oracle:thin: @localhost:1521:test'; //test爲數據庫的SID
String user='test';
String password='test';
Connection conn= DriverManager.getConnection(url,user,password);
4、access數據庫直連用ODBC的
Class.forName('sun.jdbc.odbc.JdbcOdbcDriver') ;
String url='jdbc: odbc: oriver={MicroSoft Access Driver (*.mdb)};DBQ='+application.getRealPath('/Data/ReportDemo.mdb');
Connection conn = DriverManager.getConnection(url,'','');
Statement stmtNew=conn.createStatement() ;

5、Informix數據庫
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爲數據庫名
Connection conn= DriverManager.getConnection(url);
6、DB2數據庫
Class.forName('com.ibm.db2.jdbc.app.DB2Driver ').newInstance();
String url='jdbc:db2://localhost:5000/sample'; //sample爲你的數據庫名
String user='admin';
String password='';
Connection conn= DriverManager.getConnection(url,user,password);
7、PostgreSQL數據庫
Class.forName('org.postgresql.Driver').newInstance();
String url ='jdbc:postgresql://localhost/myDB' //myDB爲數據庫名
String user='myuser';
String password='mypassword';
Connection conn= DriverManager.getConnection(url,user,password);
8、Sybase數據庫
Class.forName('com.sybase.jdbc.SybDriver').newInstance();
String url =' jdbc:sybase:Tds:localhost:5007/myDB';//myDB爲你的數據庫名
Properties sysProps = System.getProperties();
SysProps.put('user','userid');
SysProps.put('password','user_password');
Connection conn= DriverManager.getConnection(url, SysProps);
