Delete query not working sqlite

I am creating a app in which i have used sqlite db.I have successfully created the table and inserted data into it.But when i try to delete the data , the query doesn't seems to be working.

Code

public void deleteSubject(int Id) {
        String query = "DELETE  FROM " + TABLE_NAME + " WHERE " + DataBaseColumns.SUBJECT_ID + "=" + Id;
//        String whereClause = DataBaseColumns.SUBJECT_ID + "=?";
        database = openDb();
        Cursor cursor = null;
        try {
//            result = database.delete(TABLE_NAME, whereClause, new String[Id]);
            cursor = database.rawQuery(query, null);
        } catch (SQLiteException e) {
            Log.e("Error in delete Subjects", e.getMessage());
        }
        database = closeDb();
        cursor.close();


    }

Use execSQL() and not rawQuery() for DELETE queries.

rawQuery() only compiles the SQL but does not run it until the cursor is moved. execSQL() both compiles and runs the SQL.
