Question

在我的学校项目上工作，当我在ORDER BY方面添加到我的sql中时，我遇到了这个丢失的操作符错误，尽管其余的代码运行正常。

Set rs_fav = db_kwickfix.OpenRecordset("
    SELECT Recipe.Rec_Name 
    FROM Recipe,Favourites 
    WHERE (Recipe.RecipeID = Favourites.RecipeID) 
        AND (Favourites.UserID = " & frm_login.user_id & ") 
    ORDER BY Recipe.Rec_Name DESCENDING
    ")

Answer 1

尝试 DESC 而非 DESCENDING ，请检查ORDER BY Clause (Transact-SQL)：

ORDER BY order_by_expression
  [COLLATE collation_name]
  [ASC | DESC]
  [，... n]
  [＆lt; offset_fetch＆gt; ]

因此：

Set rs_fav = db_kwickfix.OpenRecordset("
    SELECT Recipe.Rec_Name 
    FROM Recipe,Favourites 
    WHERE (Recipe.RecipeID = Favourites.RecipeID) 
        AND (Favourites.UserID = " & frm_login.user_id & ") 
    ORDER BY Recipe.Rec_Name DESC
    ")

Answer 2

您是否考虑过使用明确的JOIN？

Set rs_fav = db_kwickfix.OpenRecordset("
        SELECT Recipe.Rec_Name 
        FROM Recipe
        JOIN Favourites
        ON Recipe.RecipeID = Favourites.RecipeID
        AND Favourites.UserID = " & frm_login.user_id & " 
        ORDER BY Recipe.Rec_Name DESC
    ")

另外，我强烈建议您查看参数化查询，以便开始养成使用它们的习惯。阅读更多相关信息here。
