How to connect java to Ms Access 2010?

问题

Does anyone have any ideas of how to connect Access 2010 to java jdbc. I use this method, but when I call it, it doesn't work:

public void loadDb(){
   try{
       Class.forName("sun.jdbc.JdbcOdbcDriver");
       File f = new File(System.getProperty("user.dir"))       
       con = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Acess Driver (*.mdb, *.accdb)}; DBQ="+ f.getPath() + "//db//JavaAccess.accd","","");
       st = con. createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
   }catch(ClassNotFoundException e){e.printStackTrace();
   }catch(SQLException e){e.printStackTrace();}
}

//con and st are already defined

回答1:

According to msdn it should be sun.jdbc.odbc.JdbcOdbcDriver. So replace this line of code:

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

Spelling error? Perhaps this line:

con = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Acess Driver (*.mdb, *.accdb)}; DBQ="+ f.getPath() + "//db//JavaAccess.accd","","");

should be

con = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)}; DBQ="+ f.getPath() + "//db//JavaAccess.accd","","");

Access has 2 C's

Create connection

public static Connection getConnection() {
     String driver = "sun.jdbc.odbc.JdbcOdbcDriver";
        String url = "jdbc:odbc:anime"; //anime is the database
        String username = "ipieluser"; //leave blank if none
        String password = "ipielpassword"; //leave blank if none
        try {
      Class.forName(driver);
     } catch (ClassNotFoundException e) {
      e.printStackTrace();
     }
        try {
      return DriverManager.getConnection(url, username, password);
     } catch (SQLException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
     }
     return null;
    }

How to call:

public static void main(String args[]) {
 try {
  Connection conn = getConnection();
     Statement st = conn.createStatement();
     st = conn.createStatement();
     ResultSet rs = st.executeQuery("SELECT * FROM localTable");     

  //get and displays the number of columns
     ResultSetMetaData rsMetaData = rs.getMetaData();
  int numberOfColumns = rsMetaData.getColumnCount();
     System.out.println("resultSet MetaData column Count=" + numberOfColumns);

     st.close();
     conn.close();
 } catch(Exception e) {
  System.out.println(e.getMessage());
 }
}

回答4:

Use UCanAccess JDBC Driver :

Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");  // can be omitted in most cases
Connection conn=DriverManager.getConnection("jdbc:ucanaccess://<mdb or accdb file path>",user, password);

e.g.:

Connection conn=DriverManager.getConnection("jdbc:ucanaccess://c:/pippo.mdb");

So for your example it will be

con = DriverManager.getConnection("jdbc:ucanaccess://"+f.getPath()+"/db/JavaAccess.accd")

Rishab's reply helped me to connect to my access database.

I did following correction in the code:

Instead of

String url = "jdbc:odbc:anime"; //anime is the database

I did

String url = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)}; DBQ=" + "d://institute//institutedata.accdb";

I explicitly defined driver and full database name with path and extension.

As today only we face the same problem and found that to check the version of java if your version of java if the version of the java is above 7 then the sun.jdbc.odbc.JdbcOdbcDriver will not be supported so just check the version of the java.
