我有一个计算列，用于检查＆＃34;上次付款＆＃34;退出日期不到90天。＆＃34; withdrawdate＆＃34;。表达：
IIf(DateDiff('d',[Last Payment],[withdrawaldate])<=90,'1')
如果我在sql视图中编辑它，它可以很好地工作。但是，如果我使用查询构建器编辑它，它会中断并说“＃34;语法无效＆＃34;突出显示＆＃39; 1＆＃39;作为无效部分。
＆＃34;上次付款＆＃34;如果有任何差异，也是一个计算字段？
我错过了什么？
请帮忙
提前致谢！

SQL视图如下：
SELECT
Book.Cause_Date,
Book.Is_Archived,
Book.Status, Book.Handover_Status,
Max(Payments.[Capture Date]) AS [Last Payment],
Withdrawaltest.ACCOUNTNO,
Withdrawaltest.WITHDRAWALDATE,
Withdrawaltest.WITHDRAWALREASON,
IIf(Abs(DateDiff('d',[Last Payment], [WITHDRAWALDATE])<=90)='1',"Yes","No") AS [Paid in 90Days],
IIf((Abs(DateDiff('m',[Cause_Date],[WITHDRAWALDATE])<=14)='1' And [Handover_Status]='3') Or (Abs(DateDiff('m',[Cause_Date], [WITHDRAWALDATE])<=9)='1' And [Handover_Status]='1'),'No','Yes') AS [Out Of Term],
IIf([Paid in 90Days]="Yes" Or [Out Of Term]="No","KEEP","DontBother") AS [Keep?]
FROM
Payments RIGHT JOIN (Book INNER JOIN Withdrawaltest ON Book.Case_Reference = Withdrawaltest.ACCOUNTNO) ON Payments.[Case Reference] = Withdrawaltest.ACCOUNTNO
GROUP BY
Book.Cause_Date, Book.Is_Archived,
Book.Status, Book.Handover_Status, Withdrawaltest.ACCOUNTNO,
Withdrawaltest.WITHDRAWALDATE, Withdrawaltest.WITHDRAWALREASON,
IIf((Abs(DateDiff('m',[Cause_Date],[WITHDRAWALDATE])<=14)='1' And [Handover_Status]='3') Or (Abs(DateDiff('m',[Cause_Date],
[WITHDRAWALDATE])<=9)='1' And [Handover_Status]='1'),'No','Yes')
ORDER BY
Max(Payments.[Capture Date]) DESC;
答案 0 :(得分：0)
首先，你的表达式缺少＆＃34; False＆＃34; IIf的一部分：
IIf(DateDiff('d',[Last Payment],[withdrawaldate])<=90, '1', <FALSE-PART>)
其次，如果您使用德语访问，则必须使用;代替,来查询查询设计视图中的功能。
IIf(DateDiff('d';[Last Payment];[withdrawaldate])<=90; '1'; <FALSE-PART>)
但是在SQL视图中（＆＃39; s＆＃34; international＆＃34;）它是,。
