Un exemple vaut parfois mieux que de longues explications :
SELECT biblio.datecreated AS Date_creation, biblio.title AS Titre, biblio.author AS Auteur, items.itemcallnumber AS Cote FROM items , biblio, biblioitems WHERE biblio.datecreated BETWEEN <<date de creation BETWEEN (yyyy-mm-dd)|date>> AND <<and (yyyy-mm-dd)|date>> AND biblio.biblionumber = items.biblionumber AND biblioitems.biblionumber = items.biblionumber
Résultat :
