Java连接数据库

Java连接数据库

 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
odbc 连接
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection("jdbc:odbc:数据源","用户名","密码");
调用存储过程
CallableStatement st = conn.prepareCall({call inertTable(?,?)}); // 嵌入SQL
st.setInt(1,224);
st.setInt(2,43);
st.executeUpdate();

  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);
