The programming language XQuery defines FLWOR (pronounced 'flower') as an expression that supports iteration and binding of variables to intermediate results. FLWOR is an acronym: FOR, LET, WHERE, ORDER BY, RETURN. FLWOR is loosely analogous to SQL's SELECT-FROM-WHERE and can be used to provide join-like functionality to XML documents. * for creates a sequence of nodes * let binds a sequence to a variable * where filters the nodes on a boolean expression * order by sorts the nodes * return gets evaluated once for every node

  • Мова програмування XQuery визначає FLWOR (вимовляється як «flower») як вирази, які підтримують ітерацію та прив’язування змінних до проміжних результатів. FLWOR — це абревіатура: FOR, LET, WHERE, ORDER BY, RETURN. FLWOR майже аналогічний SELECT-FROM-WHERE SQL і може використовуватися для надання функціональних можливостей, подібних до XML-документів.

  • Il linguaggio di programmazione XQuery definisce FLWOR (pronunciato flower - in italiano fiore - anche abbreviato FLWR) come un'espressione che supporta iterazione e binding sulle variabili dei risultati intermedi. FLWOR è un acronimo, dove ogni lettera è l'iniziale di una clausola: * FOR - crea una sequenza di nodi * LET - collega una sequenza di nodi ad una variabile * WHERE - filtra i nodi che soddisfano una condizione booleana * ORDER BY - ordina i nodi * RETURN - viene valutata una volta per ogni nodo (it)
