Question

database returns a null, despite there being records in the database

     private static final String DATABASE_NAME="PlayGamesdb";
     private static final String DATABASE_TABLE="peopleTable";

   public int fetchPlacesCount() {
        int count = 0;
        //String[] columns = new String[] {KEY_ROWID, KEY_NAME, KEY_HITS };
        Cursor c = ourDatabase.rawQuery("SELECT COUNT(*) from DATABASE_TABLE", null);
        c.moveToFirst();
        count = c.getInt(0);    
        return count;
    }

any ideas on what is wrong?

01-24 19:30:23.050: E/AndroidRuntime(1761): FATAL EXCEPTION: main

here is the onclick that in the other class used to call the fetchPlacesCount method

 case R.id.bSQLnumberofrows:
        int x = 0;
        PlayGame ec = new PlayGame(this);
        ec.open();
        x = ec.fetchPlacesCount();
        ec.close();
        sqlRow.setText(x);
        break;

EDIT:

after fixing the problems the code below is now working and shows the correct number of rows as a Toast message, so now one problem fixed and one more to go, still error with the setText method for putting the number in the EditText. that is what I will work on next, to see what is wrong with this textView.

using the Toast message was a good way to find out that the method was returning the correct number.

public int fetchPlacesCount() {
        int count = 0;
        Cursor q = ourDatabase.rawQuery("SELECT COUNT(*) from " + DATABASE_TABLE, null);
        q.moveToFirst();
       count = q.getInt(0);
        return count;
    }

int the other class

    case R.id.bSQLnumberofrows:
        PlayGame ec = new PlayGame(this);
        ec.open();
        int x = ec.fetchPlacesCount();
        ec.close();
      //  sqlRow.setText(x);
        Toast.makeText(SQLiteExample.this, "value of x " + x , Toast.LENGTH_SHORT).show();
        break;

Answer 1

I think you should return the cont variable instead of count as you are not assigning any value to count variable.

int cont = c.getInt(0); 
    return cont;

EDITED:

Fire your query as below:

Cursor c = ourDatabase.rawQuery(“SELECT COUNT(*) from ” + DATABASE_TABLE, null);
