Android's SQLite, how to turn Cursors into strings?

Say I have such helper:

public class SqlHelper extends SQLiteOpenHelper {

    public SqlHelper(Context context, String name, CursorFactory factory, int version) {
        super(context, name, factory, version);
        // TODO Auto-generated开发者_JAVA百科 constructor stub
    }

    @Override
    public void onCreate(SQLiteDatabase db) {

        db.execSQL("CREATE TABLE MyTable (ID INTEGER PRIMARY KEY, NAME TEXT, PLACE TEXT)");
        db.execSQL("INSERT INTO MyTable (NAME, PLACE) VALUES('ANTHONY','USA')");
        db.execSQL("INSERT INTO MyTable (NAME, PLACE) VALUES('BERIMOR','UK')");
        db.execSQL("INSERT INTO MyTable (NAME, PLACE) VALUES('IVAN','RUSSIA')");
    }


    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // TODO Auto-generated method stub
    }


}

and in my main code I execute a query

    SqlHelper sqlHelper = new SqlHelper(this, "MyDataBase.db", null, 1);
    SQLiteDatabase DB = sqlHelper.getReadableDatabase();

    Cursor c = DB.query(
            "MyTable" /* table */,
            new String[] { "PLACE" } /* columns */,
            "id = ?" /* where or selection */,
            new String[] { "RUSSIA" } /* selectionArgs */,
            null /* groupBy */,
            null /* having */,
            null /* orderBy */
        );

    DB.close();

But I'm not sure what that cursor thing is? Shouldn't it be something like an array? And if so, how do I get original values ( strings ) out of it? Like this query should return 'IVAN'.

Thanks!

EDIT2 :

This ( c.getCount() ) still returns 0, i.e. no results... hmm... maybe then there's something with the helper?

     Cursor c = DB.query(
                "MyTable" /* table */,
                new String[] { "NAME" } /* columns */,
                "PLACE = 'RUSSIA'" /* where or selection */,
                null /* selectionArgs */,
                null /* groupBy */,
                null /* having */,
                null /* orderBy */
            );



    Log.e("DB RETURNS", String.valueOf( c.getCount() ) );

The Cursor object returned by a query provides access to a recordset of results.

Once you have the Cursor, you have to iterate through it to get the values. In your case, you would do it like so --

if (cur.moveToFirst()) {
    int placeColumn = cur.getColumnIndex("PLACE"); 
    String place = cur.getString(placeColumn);
}

To get the NAME out based on a query by PLACE, you should do PLACE = ?

 Cursor c = DB.query(
            "MyTable" /* table */,
            new String[] { "NAME" } /* columns */,
            "PLACE = ?" /* where or selection */,
            new String[] { "RUSSIA" } /* selectionArgs */,
            null /* groupBy */,
            null /* having */,
            null /* orderBy */
        );

A cursor is a pointer to the results set of your query. Read the Cursor documentation here: http://developer.android.com/reference/android/database/Cursor.html

Basically, you'll do something like:

String place;
if (c.moveToFirst){
    place = c.getString( c.getColumnIndex("PLACE"));
}
