Reservierte Schlüsselwörter (Setup)
SQL Server verwendet reservierte Schlüsselwörter, um Datenbanken zu definieren, zu bearbeiten und hinzuzufügen. Reservierte Schlüsselwörter sind Teil der Transact-SQL-Grammatik, die von SQL Server verwendet wird, um Transact-SQL-Anweisungen und -Batches zu analysieren und zu verstehen.
SQL Server-Instanznamen dürfen nicht mit einem reservierten Schlüsselwort übereinstimmen. Verwenden Sie die folgende Tabelle, um sicherzustellen, dass reservierte Schlüsselwörter nicht in SQL Server-Instanznamen verwendet werden.

Darüber hinaus definiert der ISO-Standard eine Liste mit reservierten Schlüsselwörtern. Sie sollten keine dieser in ISO reservierten Schlüsselwörter für Objektnamen und -bezeichner verwenden. Die Liste der reservierten ODBC-Schlüsselwörter, die in der folgenden Tabelle aufgeführt werden, stimmt mit der Liste der reservierten ISO-Schlüsselwörter überein.
Hinweis
|
|---|
|
Die Liste der reservierten ISO-Schlüsselwörter kann in einigen Fällen stärker eingeschränkt sein als die von SQL Server, in anderen Fällen dagegen weniger. Beispielsweise enthält die Liste der reservierten ISO-Schlüsselwörter INT. SQL Server behandelt INT nicht als reserviertes Schlüsselwort. |
Die folgenden Wörter sind für die Verwendung in ODBC-Funktionsaufrufen reserviert. Diese Wörter schränken die minimale (minimum) SQL-Grammatik nicht ein. Damit jedoch die Kompatibilität mit Treibern sichergestellt ist, die die zentrale (core) SQL-Grammatik unterstützen, sollten Sie diese Schlüsselwörter nach Möglichkeit nicht in SQL Server-Instanznamen verwenden.
