我有一個錯誤關鍵字「‘聲明’附近有語法錯誤。」當時創建視圖Plz給我一個解決方案如何創建此視圖

Answer 1

視圖必須是單個SELECT語句。您可以在CREATE VIEW for SQL Server 2008的定義中閱讀此內容。

更正式的語法是：

CREATE VIEW [ schema_name . ] view_name [ (column [ ,...n ]) ] 
[ WITH <view_attribute> [ ,...n ] ] 
AS select_statement 
[ WITH CHECK OPTION ] [ ; ] 

你可以看到你創建視圖的select_statement中。您可以提供任何選擇語句，而不再提供。

如果您需要動態SQL來生成該語句，唯一的選擇是使用存儲過程。
