FLWOR (original) (raw)
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

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 FLWOR è vagamente analogo al costrutto SELECT-FROM-WHERE del linguaggio SQL e può essere usato per fornire funzionalità analoghe al join ai documenti XML. (it) 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.
