ist in der Datenbank, aber ausserhalb jeder Transaktionskontrolle. 2.2. Was ist eine Sequenz? “Sequence” ist der offizielle SQL-Begriff für das, was Firebird einen Generator nennt. Da Firebird ständig 2 an den Begriff SEQUENCE als Synonym für GENERATOR benutzen. Es wird in der Tat empfohlen, in neuem SQL-Code die SEQUENCE-Syntax zu verwenden. Auch wenn das Schlüsselwort “SEQUENCE” die Betonung auf Erzeugung der Werte zu deuten scheint, gibt es keinerlei Unterschied in Firebird zwischen einer SEQUENCE und einem GENERATOR. Es sind einfach zwei Namen für das gleiche Datenbankobjekt. Man kann einen
