「保留字」是對 Microsoft Access 有特殊意義的字與符號。 如果您使用保留字或符號為桌面資料庫或 Web 應用程式表格中的欄位命名,Access 會警告您該字已保留,且當您參照該欄位時可能會遇到錯誤。

如果使用保留字為控制項、物件或變數命名,也可能會遇到錯誤。 您收到的錯誤訊息不一定會告訴您問題的原因是保留字。 因此,可能難以確定應該變更的是什麼。 例如,Access 可能顯示類似以下的訊息:

精靈無法預覽您的報表,可能是因為報表所需的表格被獨佔鎖定。

如果保留字已在使用中,可以在該字出現的每個地方括上方括號 ([ ]) 以避免錯誤訊息。 不過,最好的解決方案是將名稱改為未保留的字。

附註:  提供所有保留字的清單不太務實,例如內建函數名稱或使用者定義名稱。 如果您設定指向類型程式庫、物件程式庫或 ActiveX 控制項的參照,該程式庫的保留字也會是您資料庫中的保留字。

Access 資料庫引擎保留字

Access 資料庫引擎會以不同模式執行,取決於呼叫它的是 Access、資料存取物件、Access 資料庫引擎的 Microsoft OLE 提供者或 Microsoft Access ODBC 驅動程式。 它可以 ANSI 模式或非 ANSI (傳統) 模式執行。

由於使用這兩個模式會產生兩組稍微不同的保留字,因此使用保留字的的查詢可能會在其中一個模式成功,卻在另一個模式中失敗。

下列為選擇識別碼名稱時應避免的保留字清單。
