Not Like Operator 无法使用 ACCESS/SQL 查询

Question

我目前正在尝试排除带有“Not Issue”字样的评论，但由于某种原因它部分有效。 当我删除下面的代码时，我得到了 100 个值，但是当我在下面添加语法时它返回 50，但是在这 50 个字段中，仍然有一些行包含“Not Issue”。

INSERT INTO Combined_Comments ( [ID], [Comment] ) 
SELECT [Comments_001].[ID], IIf([Comments]<>" ","BR
#" & [Branch Number] & " - " & [Comments],[Comments]) AS [Dup Comment] 
FROM [Comments_001] 
WHERE ((Not (IIf([Comments]<>" ","BR #" & [Branch Number] & " - " & [Comments],[Comments]))<>"%not issue%") AND (([Dup Vin Comments_085].[Dup Ind])<>" "));

Answer 1

在 MS Access 中，类似的通配符是“*”，而在 SQL 服务器中是“%”，因此查询中的 sql 应该是：

INSERT INTO Combined_Comments ( [ID], [Comment] ) 
SELECT [Comments_001].[ID], IIf([Comments]<>" ","BR
#" & [Branch Number] & " - " & [Comments],[Comments]) AS [Dup Comment] 
FROM [Comments_001] 
WHERE ((Not (IIf([Comments]<>" ","BR #" & [Branch Number] & " - " & [Comments],[Comments])) not like "*not issue*") AND (([Dup Vin Comments_085].[Dup Ind])<>" "));

我看到很多“非”运算符，并假设双重否定可以满足您的需求。
