extends SqlWindowingPagingQueryProvider
```
Derby implementation of a PagingQueryProvider using standard SQL:2003 windowing functions. These features are supported starting with Apache Derby version 10.4.1.3. As the OVER() function does not support the ORDER BY clause a sub query is instead used to order the results before the ROW_NUM restriction is applied
