Want to retrieve SQlite data and set it to map markers[ForceClose]

I have an SQLite DB that's storing all coordinates + description to show them when taping on markers. I'm using this code to retreive all descriptions:

protected boolean onTap(int index) {
            db = openHelper.getWritableDatabase();
           String[] result_columns = new String[] {COL_DESCRI};
            Cursor cur = db.query(true, TABLE_COORD, result_columns,
             null, null, null, null, null, null);
             cur.moveToFirst();
             while (cur.isAfterLast() == false) {
                String description = cur.getString(cur.getColumnIndexOrThrow("Description"));

                AlertDialog.Builder dialog = new AlertDialog.Builder(Geo.this);
                dialog.setTitle("Infos.");
                dialog.setMessage(description);
                dialog.setPositiveButton("OK", new OnClickListener() {    
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                });
                dialog.show();

                cur.moveToNext();
             }
             cur.close();
             db.close();

            return true;

However, i'm having a weird problem that indicates that i'm not having Description column and i'm pretty sure that i have it.

What could be the problem please? Thanks for helping.

Please check your create statements and queries. I would use lower case everywhere. In an edit you write coordoonnees and table_coordoonnees. Both don't match.

SQLites error messages are very helpful always. If SQLite tells you about a missing table or column this item is definetely missing or mis-spelled.

It looks like "no such column: Description" and so you have to check your database once and also you are going in a wrong direction.

You are fetching co-ordinates in onTap() method and after getting cursor you are fetching loop and in loop you have write a code for display dialog.

So your code will give you description of only last record.

You have to create array of description for all co-ordinates and then in onTap(int index) you have to get co-ordinates using index variable of onTap(int index) method
