Falsche Syntax in der Nähe des Schlüsselwortes

Question

Mein Code scheint korrekt. Aber wenn ich die Group Schlüsselwort in der Abfrage hinzufügen erzeugt er eine Nachricht an:

falsche Syntax nahe dem Schlüsselwort ‚Gruppe‘

aber wenn ich entfernen Sie das Group Schlüsselwort das Programm erfolgreich ausgeführt wird.

Answer 1

Sein Sie einen Fehler geben, weil Group ist ein Schlüsselwort (Wörter, die eine besondere Bedeutung in SQL wie Select und from haben). Dieser Group steht in Konflikt mit Group By und Sie verwenden es als Spaltenname. Sie sollten Ihren Spaltennamen in der Tabelle in etwas wie Groupname oder GroupType alles ändern, das kein Schlüsselwort in SQL ist. Dies wird den Fehler beheben.

Answer 2

Sieht aus, als ob Sie eine Spalte mit dem Namen Group haben, aber es ist ein Schlüsselwort Ich schlage also vor, dass Sie den Spaltennamen ändern (wenn er keine strengen Codierungsänderungen benötigt) oder einfach in ein Paar [] einfügen [Group]. Denken Sie daran, es ist keine gute Übung, solche Keywords für andere Zwecke zu verwenden, sie sind bereits für andere Zwecke reserviert.
