    2004-9-27 · Previous semantic definitions typically agree in the nonrecursive case, but the picture is less clear for recursion. Some proposals explicitly avoid recursive aggregates, most others differ, and many of them do not satisfy desirable criteria, such as minimality or coincidence with answer sets in the aggregate-free case.

    2013-3-24 · 1 Answer1. Show activity on this post. You really have to approach this sort of problem in two phases. The first is to create a data set you can aggregate across (recursion, the CTE) and the second is the aggregation. The approach for the aggregation would seem to me to be a window function.

  • Recursive and Nonrecursive CTE (Common Table

    Recursive Common Table Expression : A recursive CTE is one that references itself within that CTE. The recursive CTE is useful when working with hierarchical data because the CTE continues to execute until the query returns the entire hierarchy. A typical example of hierarchical data is a table that includes a list of employees.

Consequently, our approach is applicable to grounding based on semi-naive database evaluation techniques. In particular, we provide a series of algorithms detailing the treatment of recursive aggregates and illustrate this by a running example.
