JAVA连接数据库大全

Java连接数各种据库的方式总结：

1．Oracle8/8i/9i数据库（thin模式）

Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
String url="jdbc:oracle:thin:@localhost:1521:ts"; //ts为数据库的SID
String user="sa"; 
String password=""; 
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/stu"; //stu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);

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("/Accesstest.mdb");
Connection conn = DriverManager.getConnection(url,"","");
Statement stmtNew=conn.createStatement() ;
