保留關鍵字 (Transact-SQL)

Microsoft SQL Server 利用保留的關鍵字來定義、操作和存取資料庫。 保留的關鍵字是 SQL Server 用來剖析及了解 Transact-SQL 陳述式和批次之 Transact-SQL 語言文法的一部分。 雖然在語意上可以利用 SQL Server 保留關鍵字做為 Transact-SQL 指令碼中的識別碼及物件名稱,但您必須分隔這些識別碼。

下表列出 SQL Server 保留關鍵字。

另外,ISO 標準也定義了一份保留關鍵字的清單。 請避免在物件名稱和識別碼上使用 ISO 保留關鍵字。 下表所顯示的 ODBC 保留關鍵字清單與 ISO 保留關鍵字清單相同。

[!附註]

ISO 標準保留關鍵字清單有時限制性大於 SQL Server,有時比較小。 例如,ISO 保留關鍵字清單包含 INT。 SQL Server 並不需要將它視為保留關鍵字。

Transact-SQL 保留關鍵字可用來作為資料庫或資料庫物件 (如資料表、資料行、檢視等) 的識別碼或名稱。 請使用附加引號的識別字或分隔的識別碼。 利用保留關鍵字作為變數和預存程序參數的名稱,並不會受到限制。

ODBC 保留關鍵字

以下是 ODBC 函數呼叫所用的保留字。 這些字並不會限制最基礎的 SQL 文法;不過,為了確保與支援核心 SQL 文法的驅動程式相容,應用程式應該避免使用這些關鍵字。

這是目前的 ODBC 保留關鍵字清單。
