“…This paper concludes the research conducted in the field of providing a programmer with benefits of recursive queries. Other research topics dealt with Oracle's Connect by constructs [7], enhancing different ORMs with RCTE supports [9,10], unrolling of recursive queries to support DBMSs without RCTE support [8], and benefits of utilizing Pobrane z czasopisma Annales AI-Informatica http://ai.annales.umcs.pl Data: 17/09/2020 19:33:03 U M C S recursion in different cases [11,12] and with different data sets. We have also studied efficiency of execution of recursive queries in different DBMSs [1].…”

<p class="artSummaryshort">Object Relational Mappings reduce a gap between Relational Databases and programming languages. However, only the simplest operations are covered by the ORM frameworks. Most facilities provided by DBMSs are not usable via ORM. Among such features are recursive queries, introduced in SQL:99 standard. This paper presents integration of Recursive Common Table Expressions with Doctrine Query Language - a part of Doctrine ORM framework for PHP.</p>

“…Moreover, as we have already mentioned, various implementations may differ significantly from each other. The initial prototype introducing the concept of server-side recursion into a HQL language was presented in [7]. It added support for recursive Connect By queries available in the Oracle database.…”
